    Large-scale population cohort studies that collect genomic information are tasked with returning an assessment of genetic risk for hereditary cancers to participants. While several studies have applied to return identified genetic risks to participants, comprehensive surveys of participants' understanding, feelings, and behaviors toward cancer risk remain to be conducted. Here, we report our experience and surveys of returning genetic risks to 100 carriers of pathogenic variants for hereditary cancers identified through whole genome sequencing of 50 000 individuals from the Tohoku Medical Megabank project, a population cohort study. The participants were carriers of pathogenic variants associated with either hereditary breast and ovarian cancer (n = 79, median age=41) or Lynch syndrome (n = 21, median age=62). Of these, 28% and 38% had a history of cancer, respectively. We provided information on cancer risk, heritability, and clinical actionability to the participants in person. The comprehension assessment revealed that the information was better understood by younger (under 60 years) females than by older males. Scores on the cancer worry scale were positively related to cancer experiences and general psychological distress. Seventy-one participants were followed up at Tohoku University Hospital; six females underwent risk-reducing surgery triggered by study participation and three were newly diagnosed with cancer during surveillance. Among first-degree relatives of hereditary breast and ovarian cancer carriers, participants most commonly shared the information with daughters. This study showed the benefits of returning genetic risks to the general population and will provide insights into returning genetic risks to asymptomatic pathogenic variant carriers in both clinical and research settings.

    PURPOSE: To examine the prevalence of epiretinal membrane (ERM) according to the OCT-based severity scales, and to describe associations focusing on the impact of smoking and axial length of the globe. DESIGN: Cross-sectional study. PARTICIPANTS: The baseline examination cohort comprised participants from the Tohoku Medical Megabank community cohort recruited from 2013 to 2017. METHODS: In total, 38 118 eyes of 19 486 participants were classified with ERM staging. The characteristics of ERM severity were analyzed, and the association between the prevalence of ERM and ocular and systemic parameters was investigated using logistic regression models. Cubic spline models were constructed to visualize the relationships with lifetime smoking exposure and axial lengths. Regarding ERM severity, the associations between stage 1 and stage 2 or more were analyzed with multivariate analysis. MAIN OUTCOME MEASURES: Epiretinal membrane prevalence at each stage determined via OCT and factors associated with ERM presence and severity. RESULTS: The prevalence of ERM was 2.3% per eye (3.6% per person), with a predominance at stage 1. The presence of severe ERM stages was higher in older individuals. The multivariate logistic analysis revealed that older age, female sex, and long axial length were associated with a higher prevalence of ERM. In a multivariate analysis stratified by sex, glaucoma was also identified as a significant factor associated with the prevalence of ERM in women. In the cubic spline model, no consistent trend was observed between smoking and ERM prevalence. However, a U-shaped relationship was indicated between axial length and ERM prevalence. Epiretinal membrane severity highlighted older age, alcohol consumption, and very long axial length as significantly associated compared with stage 1. CONCLUSIONS: Epiretinal membrane prevalence was significantly associated with older age, female sex, and long axial length.

    BACKGROUND: The Tohoku Medical Megabank Project has initiated the Birth and Three-Generation Cohort Study (TMM BirThree Cohort Study) including genomic and omics investigations, and conducted a self-administered food frequency questionnaire with the response option "constitutionally unable to eat or drink it" for individual food items (TMM-FFQ) for pregnant women. This study evaluated the validity of the TMM-FFQ among pregnant women. METHODS: Participants comprised 122 pregnant women aged ≥20 years residing in Miyagi Prefecture who completed weighed food records (WFRs) for 3 days as reference intake and the TMM-FFQ during mid-pregnancy. Correlations between nutrient or food group intakes based on the WFR and the TMM-FFQ were calculated using Spearman's rank correlation coefficients (CCs), adjusting for energy intake and correcting for random within-individual variation of WFR. Cross-classification was also conducted according to quintiles using the WFR and TMM-FFQ data. RESULTS: The percentages of participants who chose the "constitutionally unable to eat or drink it" option were >3% for seven food and drink items. CCs were >0.30 for 31 nutrients; the median across energy and 44 nutrients was 0.41. CCs were >0.30 for 14 food groups; the median across 20 food groups was 0.35. The median percentages of cross-classification into exact plus adjacent quintiles and extreme quintiles were 63.1% and 3.3% for energy and nutrients and 61.9% and 4.1% for food groups, respectively. CONCLUSIONS: The validity of the TMM-FFQ compared with the WFR was reasonable for certain nutrients and food groups among pregnant women in the TMM BirThree Cohort Study.

    BACKGROUND: Dementia is age-related with a significant genetic contribution, yet genome-wide association studies have not fully accounted for heritability. This discrepancy may in part be due to reliance on SNPs and small indels. Whole-genome sequencing (WGS) data in the Japanese population may reveal population-specific susceptibility loci for dementia. Retinal imaging with optical coherence tomography (OCT) is noninvasive, reproducible, and can detect thinning associated with progressive neurodegeneration. Association of population-specific genetic susceptibility loci with retinal thinning and cognitive decline may reveal novel aspects of dementia risk and pathophysiology. METHOD: Among participants with WGS data from the Tohoku Medical Megabank Organization (ToMMo) Ophthalmology Study ("ToMMo Eye Study"), individuals with adequate quality data on retinal nerve fiber layer and ganglion cell layer thickness from spectral-domain optical coherence tomography (SD-OCT) scans were selected. Since retinal thinning also occurs in glaucoma, we performed a GWAS using age, sex, and 10 principal components as covariates using SAGE1.2 to obtain a set of genes responsible for glaucoma and confirm that the genotyping was successful. We then attempted to identify susceptibility loci for cognitive decline by using (1) the Mini-Mental State Examination, Japanese version (MMSE-J), (2) the Montreal Cognitive Assessment, Japanese version (MoCA-J), and (3) the Mini-COG© (a simple screening for early detection of dementia, Japanese version) scores as associated factors, respectively. Furthermore, these validation results were also compared with those obtained from GWAS using imputation data performed on custom arrays (Japonica ArrayTM, v2 or NEO) for Japanese. RESULT: 84 significant (p < 5.0E-8) genome-wide susceptibility loci (hg38) of RNFL were detected on 14K WGS-based study (the top hit locus: Chr14, SIX6 gene, P = 4.50E-46). There were many genetic loci that have already been reported to be associated with glaucoma susceptibility, including the above locus. Among the results of GWAS for cognitive decline combining the three cognitive scores after normalization to z-scores, several loci have shown significant susceptibility in both of RNFL and cognitive rating scale. Some loci suggested more than a high or moderate effect of altering protein efficacy. CONCLUSION: We present an initial WGS-based genetic study of retinal thickness and cognitive decline in the Japanese population.

    <jats:title>Abstract</jats:title><jats:p>The KEAP1–NRF2 system induces the expression of antioxidant genes in response to various types of oxidative stress. Some cancer cells activate this system, which increases their malignancy through genetic mutations. We performed a retrospective cohort study using the C‐CAT database, which contains the gene‐panel sequence data from 60,056 cases of diagnosed solid tumors. We analyzed somatic mutations in <jats:italic>NRF2</jats:italic> and <jats:italic>KEAP1</jats:italic> genes and their associations with clinical outcomes. Variants in the <jats:italic>NRF2</jats:italic> gene were clustered in exon 2, which encodes the DLG and ETGE motifs essential for KEAP1 interaction. The <jats:italic>NRF2</jats:italic> variants were frequently observed in esophageal and lung squamous cell carcinoma with frequencies of 35.9% and 19.6%, respectively. Among these mutations, the <jats:italic>NRF2</jats:italic> variants in the ETGE motif were indicators of a worse prognosis. <jats:italic>KEAP1</jats:italic> variants were found in 2.5% of all cases. The variants were frequent in lung cancer and showed a worse prognosis in lung and other types of adenocarcinomas. We then conducted gene expression analysis using TCGA data. While cancers with DLG and ETGE variants were similar in terms of gene expression profiles, there were significant differences between cancers with <jats:italic>KEAP1</jats:italic> and <jats:italic>NRF2</jats:italic> variants. Our results indicate that genetic alteration of the KEAP1–NRF2 pathway is a major factor in patient prognosis for each cancer type and its genetic variant. Variants in <jats:italic>NRF2</jats:italic> and <jats:italic>KEAP1</jats:italic> genes can characterize the biological basis of each cancer type and are involved in carcinogenesis, resistance to therapy, and other biological differences.</jats:p>

    In this study, we aimed to investigate the effects of the deficient antioxidative gene, nuclear factor-erythroid 2-related factor 2 (Nrf2), on 17β-estradiol (E2)-mediated oxidative stress response, with a specific focus on growth factor production and cell death in Müller cells and retinal tissue. Administration of hydrogen peroxide (H2O2) reduced the viability of Müller cells derived from Nrf2 wild-type (WT) and knockout (KO) mice. However, this effect was more significant in the KO cells than in the WT cells. Pretreatment with E2 inhibited H2O2-induced cell death in both Nrf2 WT and KO Müller cell genotypes. Small interfering RNA-mediated gene silencing of estrogen receptor 2 (Esr2) attenuated the cell survival-promoting activity of E2 in Nrf2 KO Müller cells, while other identified estrogen receptors, Esr1 or G protein-coupled estrogen receptor 1 (Gper1), had no effect. Western blotting revealed higher ESR2 expression levels in Nrf2 KO cells than in WT Müller cells. Conditioned media from E2-and H2O2-treated Nrf2 WT or KO Müller cells enhanced the dissociated retinal cell viability compared with H2O2-treated cells. Both quantitative reverse-transcription polymerase chain reaction assay (qRT-PCR) and enzyme-linked immunosorbent assay exhibited a significant increase in fibroblast growth factor 2 (FGF2) expression levels in E2-and H2O2-treated Nrf2 WT and KO Müller cells compared to those in E2-treated cells. In vivo, administration of N-methyl-N-nitrosourea (MNU) reduced the thickness and cell density of the outer nuclear layer (ONL) in Nrf2 KO mice and enhanced the number of terminal deoxynucleotidyl transferase dUTP nick-end labeling-positive cells in the ONL. However, E2 administration attenuated these defects in MNU-treated mice. Concomitant administration of MNU and E2 enhanced FGF2 protein levels in retinal lysates of Nrf2 KO mice. In conclusion, E2 demonstrated a significant role in preventing oxidative stress-induced retinal cell death by stimulating FGF2 production in Müller cells, independent of the Nrf2 gene. Based on these findings, we anticipate that exogenous administration of estrogens or ESR2-selective agonists could aid in treating patients with oxidative stress-related retinal degenerative diseases such as age-related macular degeneration and retinitis pigmentosa.

    OBJECTIVE: To investigate the inter-relationships among genetic risk, healthy lifestyle adherence, and hyperuricaemia susceptibility. METHODS: This prospective cohort study was conducted with 7,241 hyperuricaemia-free individuals aged ≥ 20 years from the Tohoku Medical Megabank Community-based cohort study. A comprehensive lifestyle score included body mass index, smoking, drinking, and physical activity, and a polygenic risk score (PRS) was constructed based on uric acid loci from a previous genome-wide association study meta-analysis. A multiple logistic regression model was used to estimate the association between genetic risk, healthy lifestyle, and hyperuricaemia incidence and calculate the area under the receiver operating characteristic curve (AUROC). Hyperuricaemia was defined as a uric acid level ≥7.0 mg/dl or a self-reported history of hyperuricaemia. RESULTS: Of the 7,241 adults (80.7% females; mean [SD] age: 57.7 [12.6] years), 217 (3.0%) developed hyperuricaemia during 3.5 years of follow-up. Genetic risk correlated with hyperuricaemia development (P for interaction = 0.287), and lifestyle risks were independently associated. Those with a high genetic risk and poor lifestyle had the highest risk (odds ratio: 5.34; 95% confidence interval [CI]: 2.61-12.10). Although not statistically significant, incorporating the PRS in the model with lifestyle information improved predictive ability (AUROC = 0.771, 95% CI: 0.736-0.806 for lifestyle; AUROC = 0.785, 95% CI: 0.751-0.819 for lifestyle and PRS; p = 0.07). CONCLUSION: : A healthy lifestyle to prevent hyperuricaemia, irrespective of genetic risk, may mitigate the genetic risk. Genetic risk may complement lifestyle factors in identifying individuals at a heightened hyperuricaemia risk.

    Alzheimer's disease (AD) is the most common etiology of dementia. The transcription factor NF-E2-related factor 2 (NRF2) induces the expression of genes encoding phase II detoxification and antioxidant genes. NRF2 is regulated by Kelch-like ECH-associated protein 1 (KEAP1), and the KEAP1-NRF2 system is the key regulatory system involved in cytoprotection. To examine whether pharmacological induction of NRF2 expression alleviates AD phenotypes in vivo, we employed two AD mouse models, i.e., App  NL-G-F/NL-G-F (AppNLGF) and APPV717I::TAUP301L (APP/TAU) mice. As the synthetic oleanane triterpenoid 1-[2-cyano-3,12-dioxooleana-1,9(11-dien-28-oyl)] (CDDO)-4(-pyridin-2-yl)-imidazole (CDDO-2P-Im) exhibits strong NRF2-inducing activity, we treated AD model mice with CDDO-2P-Im. We found that Aβ42 levels were markedly greater in the brains of AppNLGF mice than in those of APP/TAU mice. CDDO-2P-Im treatment significantly decreased Aβ42 levels, but not Aβ40 levels, in APP/TAU mice. Consequently, CDDO-2P-Im also decreased the ratio of Aβ42/Aβ40, a vital marker of amyloid plaque formation. LC-MS/MS analyses revealed that CDDO-2P-Im was delivered to the brains of the APP/TAU mice. CDDO-2P-Im induced the expression of detoxification and antioxidant gene targets of NRF2 and elevated reduced glutathione (GSH) levels in the mouse brain. These results support the notion that CDDO-2P-Im ameliorates AD-related pathologic changes.

    PURPOSE: To explore the frequency and positions of genetic mutations in CYP1B1 and FOXC1 in a Japanese population. STUDY DESIGN: Molecular genetic analysis. METHODS: Genomic DNA was extracted from 31 Japanese patients with childhood glaucoma (CG) from 29 families. We examined the CYP1B, FOXC1, and MYOC genes using Sanger sequencing and whole-exome sequencing (WES). RESULTS: For CYP1B1, we identified 9 families that harbored novel mutations, p.A202T, p.D274E, p.Q340*, and p.V420G; the remaining mutations had been previously reported. When mapped to the CYP1B1 protein structure, all mutations appeared to influence the enzymatic activity of CYP1B1 by provoking structural deformity. Five patients were homozygotes or compound heterozygotes, supporting the recessive inheritance of the CYP1B1 mutations in CG. In contrast, four patients were heterozygous for the CYP1B1 mutation, suggesting the presence of regulatory region mutations or strong modifiers. For the FOXC1 gene, we identified 3 novel mutations, p.Q23fs, p.Q70R, and p.E163*, all of which were identified in a heterozygous state. No mutation was found in the MYOC gene in these CG patients. All individuals with CYP1B1 and FOXC1 mutations were severely affected by early-onset CG. In the CYP1B1-, FOXC1-, and MYOC-negative families, we also searched for variants in the other candidate genes reported for CG through WES, but could not find any mutations in these genes. CONCLUSIONS: Our analyses of 29 CG families revealed 9 families with point mutations in the CYP1B1 gene, and four of those patients appeared to be heterozygotes, suggesting the presence of complex pathogenic mechanisms. FOXC1 appears to be another major causal gene of CG, indicating that panel sequencing of CYP1B1 and FOXC1 will be useful for diagnosis of CG in Japanese individuals.

    INTRODUCTION: To examine the interaction between lifestyle habits and the COVID-19 vaccinations for preventing SARS-CoV-2 infection, we analyzed 11,016 adult participants registered in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. METHODS: Lifestyle variables, including regular exercise, smoking and drinking habits, sleep status, body mass index, and daily breakfast consumption, were assessed from 2014 to 2019 using baseline questionnaires. Information on SARS-CoV-2 infection and the COVID-19 vaccination were also collected from March 2020 to May 2023. The study period was divided into two in the postvaccination phase: the first period (the beginning of the vaccination program) and the second period (the fourth shot onward). RESULTS: In the Cox proportional-hazards model analysis, the five-time vaccinations group showed a significantly lower risk of SARS-CoV-2 infection adjusted age, sex, underlying health condition, and lifestyle variables (hazard ratio [HR] 0.81, 95% confidence interval [CI] 0.76-0.86). Logistic regression analysis revealed that a higher number of vaccinations was significantly associated with a low risk of SARS-CoV-2 infection regardless of lifestyle habits (three times in the first period: odds ratio [OR] 0.19, 95% CI 0.15-0.24; five times in the second period: OR 0.07, 95% CI 0.05-0.11 vs. none). Regarding lifestyle habits, the risk reduction in those who had sleep satisfaction (OR 0.12, 95% CI 0.08-0.18) was slightly larger than in those who had sleep dissatisfaction (OR 0.23, 95% CI 0.17-0.32) in the group with the highest number of vaccinations in the first period; however, this interaction was hardly confirmed in the second period when the number of infected cases significantly increased. CONCLUSIONS: Our findings indicated that a higher number of COVID-19 vaccinations was associated with reduced risk of SARS-CoV-2 infection; otherwise, we may need to understand the advantages and limitations of a healthy lifestyle for preventing infection depending on the situation with vaccinations and infection spreading.

    INTRODUCTION: The Tohoku Medical Megabank (TMM) was established for creative reconstruction from the Great East Japan Earthquake and tsunami in 2011. Two prospective genome cohort studies in Miyagi prefecture have successfully recruited approximately 127,000 participants. The health status of these individuals was evaluated at the initial recruitment, and follow-up health checkups have been conducted every 5 years. During these health checkups, unexpected critical values were encountered, which prompted us to develop an urgent notification system. METHODS: We analyzed the frequency of critical values observed in home blood pressure (HBP) test in an urgent notification office (UNO). We returned the critical values by urgent notification before the notifications of regular results. In addition, the impact of the TMM urgent notification on the participants was evaluated. RESULTS: We issued urgent notifications of the critical values of extremely high HBP. Of the 21,061 participants who underwent HBP measurements, 256 (1.2%) met the criteria for urgent notification. It was found that abnormalities in blood sugar levels, renal function, and lipid values were frequently concurrent with the abnormal HBP readings. Annual questionnaires administered after the urgent notification, approximately 60% of those went to hospitals or clinics. CONCLUSIONS: The urgent notification system for hypertensive emergency with HBP in the TMM was well accepted by the participants and encouraged them to seek medical care. The system has been useful in addressing the prolonged healthcare problems and in promoting health care in large-scale disaster damaged areas.

    Understanding the physiological changes associated with aging and the associated disease risks is essential to establish biomarkers as indicators of biological aging. This study used the NMR-measured plasma metabolome to calculate age-specific metabolite indices. In doing so, the scope of the study was deliberately simplified to capture general trends and insights into age-related changes in metabolic patterns. In addition, changes in metabolite concentrations with age were examined in detail, with the period from 55-59 to 60-64 years being a period of significant metabolic change, particularly in men, and from 45-49 to 50-54 years in females. These results illustrate the different variations in metabolite concentrations by sex and provide new insights into the relationship between age and metabolic diseases.

    No study, to our knowledge, has constructed a polygenic risk score based on clinical blood pressure and investigated the association of genetic and lifestyle risks with home hypertension. We examined the associations of combined genetic and lifestyle risks with hypertension and home hypertension. In a cross-sectional study of 7027 Japanese individuals aged ≥20 years, we developed a lifestyle score based on body mass index, alcohol consumption, physical activity, and sodium-to-potassium ratio, categorized into ideal, intermediate, and poor lifestyles. A polygenic risk score was constructed with the target data (n = 1405) using publicly available genome-wide association study summary statistics from BioBank Japan. Using the test data (n = 5622), we evaluated polygenic risk score performance and examined the associations of combined genetic and lifestyle risks with hypertension and home hypertension. Hypertension and home hypertension were defined as blood pressure measured at a community-support center ≥140/90 mmHg or at home ≥135/85 mmHg, respectively, or self-reported treatment for hypertension. In the test data, 2294 and 2322 participants had hypertension and home hypertension, respectively. Both polygenic risk and lifestyle scores were independently associated with hypertension and home hypertension. Compared with those of participants with low genetic risk and an ideal lifestyle, the odds ratios for hypertension and home hypertension in the low genetic risk and poor lifestyle group were 1.94 (95% confidence interval, 1.34-2.80) and 2.15 (1.60-2.90), respectively. In summary, lifestyle is important to prevent hypertension; nevertheless, participants with high genetic risk should carefully monitor their blood pressure despite a healthy lifestyle.

    AIM: This study examined the relationship between genetic risk, healthy lifestyle, and risk of developing diabetes. METHODS: This prospective cohort study included 11,014 diabetes-free individuals ≥ 20 years old from the Tohoku Medical Megabank Community-based cohort study. Lifestyle scores, including the body mass index, smoking, physical activity, and gamma-glutamyl transferase (marker of alcohol consumption), were assigned, and participants were categorized into ideal, intermediate, and poor lifestyles. A polygenic risk score (PRS) was constructed based on the type 2 diabetes loci from the BioBank Japan study. A multiple logistic regression model was used to estimate the association between genetic risk, healthy lifestyle, and diabetes incidence and to calculate the area under the receiver operating characteristic curve (AUROC). RESULT: Of the 11,014 adults included (67.8% women; mean age [standard deviation], 59.1 [11.3] years old), 297 (2.7%) developed diabetes during a mean 4.3 (0.8) years of follow-up. Genetic and lifestyle score is independently associated with the development of diabetes. Compared with the low genetic risk and ideal lifestyle groups, the odds ratio was 3.31 for the low genetic risk and poor lifestyle group. When the PRS was integrated into a model including the lifestyle and family history, the AUROC significantly improved to 0.719 (95% confidence interval [95% CI]: 0.692-0.747) compared to a model including only the lifestyle and family history (0.703 [95% CI, 0.674-0.732]). CONCLUSION: Our findings indicate that adherence to a healthy lifestyle is important for preventing diabetes, regardless of genetic risk. In addition, genetic risk might provide information beyond lifestyle and family history to stratify individuals at high risk of developing diabetes.

    Bcl2-associated athanogene-1 protein (Bag1) acts as a co-chaperone of heat shock protein 70 and heat shock cognate 70 and regulates multiple cellular processes, including cell proliferation, apoptosis, environmental stress response, and drug resistance. Since Bag1 knockout mice exhibited fetal lethality, the in vivo function of Bag1 remains unclear. In this study, we established a mouse line expressing Bag1 gene missing exon 5, which corresponds to an encoding region for the interface of heat shock protein 70/heat shock cognate 70. Despite mice carrying homoalleles of the Bag1 mutant (Bag1Δex5) expressing undetectable levels of Bag1, Bag1Δex5 homozygous mice developed without abnormalities. Bag1Δex5 protein was found to be highly unstable in cells and in vitro. We found that the growth of mouse embryonic fibroblasts derived from Bag1Δex5-homo mice was attenuated by doxorubicin and a glutathione (GSH) synthesis inhibitor, buthionine sulfoximine. In response to buthionine sulfoximine, Bag1Δex5-mouse embryonic fibroblasts exhibited a higher dropping rate of GSH relative to the oxidized glutathione level. In addition, Bag1 might mitigate cellular hydrogen peroxide levels. Taken together, our results demonstrate that the loss of Bag1 did not affect mouse development and that Bag1 is involved in intracellular GSH homeostasis, namely redox homeostasis.

    Genetic maps are fundamental resources for linkage and association studies. A fine-scale genetic map can be constructed by inferring historical recombination events from the genome-wide structure of linkage disequilibrium-a non-random association of alleles among loci-by using population-scale sequencing data. We constructed a fine-scale genetic map and identified recombination hotspots from 10 092 551 bi-allelic high-quality autosomal markers segregating among 150 unrelated Japanese individuals whose genotypes were determined by high-coverage (30×) whole-genome sequencing, and the genotype quality was carefully controlled by using their parents' and offspring's genotypes. The pedigree information was also utilized for haplotype phasing. The resulting genome-wide recombination rate profiles were concordant with those of the worldwide population on a broad scale, and the resolution was much improved. We identified 9487 recombination hotspots and confirmed the enrichment of previously known motifs in the hotspots. Moreover, we demonstrated that the Japanese genetic map improved the haplotype phasing and genotype imputation accuracy for the Japanese population. The construction of a population-specific genetic map will help make genetics research more accurate.

    BACKGROUND: Genetic epidemiological evidence for the kidney function traits in East Asian population including Japanese remain still relatively unclarified. Especially, the number of GWASs for kidney traits reported still remains limited, and the sample size of each independent study is relatively small. Given the genetic variability between ancestries/ethnicities, implementation of GWAS with sufficiently large sample sizes in specific population of Japanese is considered meaningful. METHODS: We conducted the GWAS meta-analyses of kidney traits by leveraging the GWAS summary data of the representative large genome cohort studies with about 200,000 Japanese participants (n = 202,406 for estimated glomerular filtration rate [eGFR] and n = 200,845 for serum creatinine [SCr]). RESULTS: In the present GWAS meta-analysis, we identified 110 loci with 169 variants significantly associated with eGFR (on chromosomes 1-13 and 15-22; p < 5×10-8), whereas we also identified 112 loci with 176 variants significantly associated with SCr (on chromosomes 1-22; p < 5×10-8), of which one locus (more than 1Mb distant from known loci) with one variant (CD36 rs146148222 on chromosome 7) for SCr was considered as the truly novel finding. CONCLUSIONS: The present GWAS meta-analysis of largest genome cohort studies in Japanese provided some original genomic loci associated with kidney function in Japanese, which may contribute to the possible development of personalized prevention of kidney diseases based on genomic information in the near future.

    Recently, many phenotyping algorithms for high-throughput cohort identification have been developed. Prospective genome cohort studies are critical resources for precision medicine, but there are many hurdles in the precise cohort identification. Consequently, it is important to develop phenotyping algorithms for cohort data collection. Hypertensive disorders of pregnancy (HDP) is a leading cause of maternal morbidity and mortality. In this study, we developed, applied, and validated rule-based phenotyping algorithms of HDP. Two phenotyping algorithms, algorithms 1 and 2, were developed according to American and Japanese guidelines, and applied into 22,452 pregnant women in the Birth and Three-Generation Cohort Study of the Tohoku Medical Megabank project. To precise cohort identification, we analyzed both structured data (e.g., laboratory and physiological tests) and unstructured clinical notes. The identified subtypes of HDP were validated against reference standards. Algorithms 1 and 2 identified 7.93% and 8.08% of the subjects as having HDP, respectively, along with their HDP subtypes. Our algorithms were high performing with high positive predictive values (0.96 and 0.90 for algorithms 1 and 2, respectively). Overcoming the hurdle of precise cohort identification from large-scale cohort data collection, we achieved both developed and implemented phenotyping algorithms, and precisely identified HDP patients and their subtypes from large-scale cohort data collection.

    INTRODUCTION: Accumulating data on the associations between food consumption and lipid composition in the body is essential for understanding the effects of dietary habits on health. OBJECTIVES: As part of omics research in the Tohoku Medical Megabank Community-Based Cohort Study, this study sought to reveal the dietary impact on plasma lipid concentration in a Japanese population. METHODS: We conducted a correlation analysis of food consumption and plasma lipid concentrations measured using mass spectrometry, for 4032 participants in Miyagi Prefecture, Japan. RESULTS: Our analysis revealed 83 marked correlations between six food categories and the concentrations of plasma lipids in nine subclasses. Previously reported associations, including those between seafood consumption and omega-3 fatty acids, were validated, while those between dairy product consumption and odd-carbon-number fatty acids (odd-FAs) were validated for the first time in an Asian population. Further analysis suggested that dairy product consumption is associated with odd-FAs via sphingomyelin (SM), which suggests that SM is a carrier of odd-FAs. These results are important for understanding odd-FA metabolism with regards to dairy product consumption. CONCLUSION: This study provides insight into the dietary impact on plasma lipid concentration in a Japanese population.

    GATA1 plays a critical role in differentiation, proliferation, and apoptosis during erythropoiesis. We developed a Gata1 knock-down allele (Gata1.05) that results in GATA1 expression at 5% of endogenous level. In female mice heterozygous for both the Gata1.05 and wild-type alleles, we observed a predisposition to erythroblastic leukemia three to six months after birth. Since no male Gata1.05 progeny survive gestation, we originally maintained heterozygous females in a mixed genetic background of C57BL/6J and DBA/2 strains. Around 30% of these mice reproducibly develop leukemia, but the other subset did not develop leukemia, even though they harbor a high number of preleukemic erythroblasts. These observations prompted us to hypothesize that there may be potential influence of genetic determinants on the progression of Gata1.05-driven hematopoietic precursors to full-blown leukemia. In an initial examination of Gata1.05/X mice backcrossed into C3H/He, BALB/c, DBA/2, C57BL/6J and 129X1/SvJ strains, we discerned that the backgrounds of C57BL/6J and 129X1/SvJ significantly expedited leukemia onset in Gata1.05/X mice. Conversely, backgrounds of C3H/He, BALB/c and DBA/2 did not substantially modify the effect of the Gata1 mutation. This indicates the existence of genetic modifiers that accentuate Gata1.05 leukemogenesis. Subsequent cohort studies evaluated Gata1.05/X mice within mix backgrounds of BALB/c:129X1/SvJ and BALB/c:C57BL/6J. In these settings, Gata1.05-driven leukemia manifested in autosomal dominant patterns within the 129X1/SvJ background and in autosomal recessive patterns within C57BL/6J background. To the best of our knowledge, this study provides the inaugural evidence of genetic modifiers that can reshape the outcome based on leukemia-associated gene signatures.

    Transcription factor GATA1 controls the delicate balance between proliferation, differentiation and apoptosis in both the erythroid and megakaryocytic lineages. In addition to full-length GATA1, there is an GATA1 isoform, GATA1s, that lacks the amino-terminal transactivation domain. Somatic GATA1 mutations that lead to the exclusive production of GATA1s appear to be necessary and sufficient for the development of a preleukemic condition called transient myeloproliferative disorder (TMD) in Down syndrome newborns. Subsequent clonal evolution among latent TMD blasts leads to the development of acute megakaryoblastic leukemia (AMKL). We originally established transgenic mice that express only GATA1s, which exhibit hyperproliferation of immature megakaryocytes, thus mimicking human TMD; however, these mice never developed AMKL. Here, we report that transgenic mice expressing moderate levels of GATA1s, i.e., roughly comparable levels to endogenous GATA1, were prone to develop AMKL in young adults. However, when GATA1s is expressed at levels significantly exceeding that of endogenous GATA1, the development of leukemia was restrained in a dose dependent manner. If the transgenic increase of GATA1s in progenitors remains small, GATA1s supports the terminal maturation of megakaryocyte progenitors insufficiently, and consequently the progenitors persisted, leading to an increased probability for acquisition of additional genetic modifications. In contrast, more abundant GATA1s expression compensates for this maturation block, enabling megakaryocytic progenitors to fully differentiate. This study provides evidence for the clinical observation that the abundance of GATA1s correlates well with the progression to AMKL in Down syndrome.

    BACKGROUND: The purpose of this study was to report the basic profile of the Miyagi Prefecture part of a repeated center-based survey during the second period (2nd period survey) of the Tohoku Medical Megabank Community-Based Cohort Study (TMM CommCohort Study), as well as the participants' characteristics based on their participation type in the baseline survey. METHODS: The 2nd period survey, conducted from June 2017 to March 2021, included participants of the TMM CommCohort Study (May 2013 to March 2016). In addition to the questionnaire, blood, urine, and physiological function tests were performed during the 2nd period survey. There were three main ways of participation in the baseline survey: Type 1, Type 1 additional, or Type 2 survey. The 2nd period survey was conducted in the same manner as the Type 2 survey, which was based on the community support center (CSC). RESULTS: In Miyagi Prefecture, 29,383 (57.7%) of 50,967 participants participated in the 2nd period survey. The participation rate among individuals who had visited the CSC was approximately 80%. Although some factors differed depending on the participation type in the baseline survey, the 2nd period survey respondents in the Type 1 and Type 2 survey groups at baseline had similar traits.

    Whole blood transcriptome analysis is a valuable approach in medical research, primarily due to the ease of sample collection and the richness of the information obtained. Since the expression profile of individual genes in the analysis is influenced by medical traits and demographic attributes such as age and gender, there has been a growing demand for a comprehensive database for blood transcriptome analysis. Here, we performed whole blood RNA sequencing (RNA-seq) analysis on 576 participants stratified by age (20-30s and 60-70s) and gender from cohorts of the Tohoku Medical Megabank (TMM). A part of female segment included pregnant women. We did not exclude the globin gene family in our RNA-seq study, which enabled us to identify instances of hereditary persistence of fetal hemoglobin based on the HBG1 and HBG2 expression information. Comparing stratified populations allowed us to identify groups of genes associated with age-related changes and gender differences. We also found that the immune response status, particularly measured by neutrophil-to-lymphocyte ratio (NLR), strongly influences the diversity of individual gene expression profiles in whole blood transcriptome analysis. This stratification has resulted in a dataset that will be highly beneficial for future whole blood transcriptome analysis in the Japanese population.

    With the number of samples increasing in many biobanks, one of the most pressing tasks is recording the correct relationships between information and the specimens. Genomic information is useful in determining the identity of these specimens. The Tohoku Medical Megabank Organization is running one of the largest biobanks in Japan. Here, we introduce a management system, which includes the development of a new probe set for the MassARRAY system for use during the production of proliferating T cells (T cells) and lymphoblastoid cell lines (LCLs). We selected single nucleotide variants that could be detected by next-generation sequencing and showed high resolution with ∼0.5 minor allele frequencies. After checking the set of probes against 96 samples from 48 people, we obtained no contradictory results in comparison with our genome sequence information. When we applied the set to our 3035 LCLs and 2256 T cells, the result showed 98.93% consistency with the corresponding genomic information. We surveyed the handling records of the 1.07% of samples that showed inconsistencies, and found that most had resulted from human errors (ID swapping between samples) during manual operations. After improving a few error-prone protocols, the error rate dropped to 0.47% for LCLs and 0% for T cells. Overall, the system that we developed shows high accuracy with easy and fast operability, and provides a good opportunity to improve the validation procedure to facilitate high-quality banking, especially in cases involving genomic information.

    Glaucoma is a leading cause of blindness worldwide in older people. Profiling the aqueous humor, including the metabolites it contains, is useful to understand physiological and pathological conditions in the eye. In the current study, we used mass spectrometry (MS) to characterize the aqueous humor metabolomic profile and biological features of patients with glaucoma. Aqueous humor samples were collected during trabeculectomy surgery or cataract surgery and analyzed with global metabolomics. We included 40 patients with glaucoma (32 with POAG, 8 with NTG) and 37 control subjects in a discovery study. VIP analysis revealed five metabolites that were elevated and three metabolites that were reduced in the glaucoma patients. The identified metabolomic profile had an area under the receiver operating characteristic curve of 0.953. Among eight selected metabolites, the glutathione level was significantly decreased in association with visual field defects. Moreover, in a validation study to confirm the reproducibility of our findings, the glutathione level was reduced in NTG and POAG patients compared with a cataract control group. Our findings demonstrate that aqueous humor profiling can help to diagnose glaucoma and that various aqueous humor metabolites are correlated with clinical parameters in glaucoma patients. In addition, glutathione is clearly reduced in the aqueous humor of glaucoma patients with both IOP-dependent and IOP-independent disease subtypes. These findings indicate that antioxidant agents in the aqueous humor reflect glaucomatous optic nerve damage and that excessive oxidative stress may be involved in the pathogenesis of glaucoma.

    Modern medicine is increasingly focused on personalized medicine, and multi-omics data is crucial in understanding biological phenomena and disease mechanisms. Each ethnic group has its unique genetic background with specific genomic variations influencing disease risk and drug response. Therefore, multi-omics data from specific ethnic populations are essential for the effective implementation of personalized medicine. Various prospective cohort studies, such as the UK Biobank, All of Us and Lifelines, have been conducted worldwide. The Tohoku Medical Megabank project was initiated after the Great East Japan Earthquake in 2011. It collects biological specimens and conducts genome and omics analyses to build a basis for personalized medicine. Summary statistical data from these analyses are available in the jMorp web database (https://jmorp.megabank.tohoku.ac.jp), which provides a multidimensional approach to the diversity of the Japanese population. jMorp was launched in 2015 as a public database for plasma metabolome and proteome analyses and has been continuously updated. The current update will significantly expand the scale of the data (metabolome, genome, transcriptome, and metagenome). In addition, the user interface and backend server implementations were rewritten to improve the connectivity between the items stored in jMorp. This paper provides an overview of the new version of the jMorp.

    Abstract Selenoprotein P (SeP) is a major selenoprotein in serum predominantly produced in the liver. Excess SeP impairs insulin secretion from the pancreas and insulin sensitivity in skeletal muscle, thus inhibition of SeP could be a therapeutic strategy for type 2 diabetes. In this study, we examine the effect of sulforaphane (SFN), a phytochemical of broccoli sprouts and an Nrf2 activator, on SeP expression in vitro and in vivo. Treatment of HepG2 cells with SFN decreases inter- and intra-cellular SeP levels. SFN enhances lysosomal acidification and expression of V-ATPase, and inhibition of this process cancels the decrease of SeP by SFN. SFN activates Nrf2 in the cells, while Nrf2 siRNA does not affect the decrease of SeP by SFN or lysosomal acidification. These results indicate that SFN decreases SeP by enhancing lysosomal degradation, independent of Nrf2. Injection of SFN to mice results in induction of cathepsin and a decrease of SeP in serum. The findings from this study are expected to contribute to developing SeP inhibitors in the future, thereby contributing to treating and preventing diseases related to increased SeP.

    AIM: The influence of family history of diabetes, probably reflecting genetic and lifestyle factors, on the association of combined genetic and lifestyle risks with diabetes is unknown. We examined these associations. METHODS: This cross-sectional study included 9,681 participants in the Tohoku Medical Megabank Community-based Cohort Study. A lifestyle score, which was categorized into ideal, intermediate, and poor lifestyles, was given. Family history was obtained through a self-reported questionnaire. A polygenic risk score (PRS) was constructed in the target data (n=1,936) using publicly available genome-wide association study summary statistics from BioBank Japan. For test data (n=7,745), we evaluated PRS performance and examined the associations of combined family history and genetic and lifestyle risks with diabetes. Diabetes was defined as non-fasting blood glucose ≥ 200 mmHg, HbA1c ≥ 6.5%, and/or self-reported diabetes treatment. RESULTS: In test data, 467 (6.0%) participants had diabetes. Compared with a low genetic risk and an ideal lifestyle without a family history, the odds ratio (OR) was 3.73 (95% confidence interval [CI], 1.92-7.00) for a lower genetic risk and a poor lifestyle without a family history. Family history was significantly associated with diabetes (OR, 3.58 [95% CI, 1.73-6.98]), even in those with a low genetic risk and an ideal lifestyle. Even among participants who had an ideal lifestyle without a family history, a high genetic risk was associated with diabetes (OR, 2.49 [95% CI, 1.65-3.85]). Adding PRS to family history and conventional lifestyle risk factors improved the prediction ability for diabetes. CONCLUSIONS: Our findings support the notion that a healthy lifestyle is important to prevent diabetes regardless of genetic risk.

    BACKGROUND: Low birth weight (LBW) is a leading cause of neonatal morbidity and mortality, and increases various disease risks across life stages. Prediction models of LBW have been developed before, but have limitations including small sample sizes, absence of genetic factors and no stratification of neonate into preterm and term birth groups. In this study, we challenged the development of early prediction models of LBW based on environmental and genetic factors in preterm and term birth groups, and clarified influential variables for LBW prediction. METHODS: We selected 22,711 neonates, their 21,581 mothers and 8,593 fathers from the Tohoku Medical Megabank Project Birth and Three-Generation cohort study. To establish early prediction models of LBW for preterm birth and term birth groups, we trained AI-based models using genetic and environmental factors of lifestyles. We then clarified influential environmental and genetic factors for predicting LBW in the term and preterm groups. RESULTS: We identified 2,327 (10.22%) LBW neonates consisting of 1,077 preterm births and 1,248 term births. Our early prediction models archived the area under curve 0.96 and 0.95 for term LBW and preterm LBW models, respectively. We revealed that environmental factors regarding eating habits and genetic features related to fetal growth were influential for predicting LBW in the term LBW model. On the other hand, we identified that genomic features related to toll-like receptor regulations and infection reactions are influential genetic factors for prediction in the preterm LBW model. CONCLUSIONS: We developed precise early prediction models of LBW based on lifestyle factors in the term birth group and genetic factors in the preterm birth group. Because of its accuracy and generalisability, our prediction model could contribute to risk assessment of LBW in the early stage of pregnancy and control LBW risk in the term birth group. Our prediction model could also contribute to precise prediction of LBW based on genetic factors in the preterm birth group. We then identified parental genetic and maternal environmental factors during pregnancy influencing LBW prediction, which are major targets for understanding the LBW to address serious burdens on newborns' health throughout life.

    BACKGROUND AIMS: Cancer cells reprogram their metabolic pathways to support bioenergetic and biosynthetic needs and to maintain their redox balance. In several human tumors the Keap1-Nrf2 system controls proliferation and metabolic reprogramming by regulating the pentose phosphate pathway (PPP). However, whether this metabolic reprogramming also occurs in normal proliferating cells is unclear. APPROACH AND RESULTS: To define the metabolic phenotype in normal proliferating hepatocytes, we induced cell proliferation in the liver by three distinct stimuli: liver regeneration by partial hepatectomy (PH) and hepatic hyperplasia induced by two direct mitogens, lead nitrate (LN) or triiodothyronine (T3). Following LN treatment, well-established features of cancer metabolic reprogramming including enhanced glycolysis, oxidative PPP, nucleic acid synthesis, NAD+/NADH synthesis and altered amino acid content as well as downregulated oxidative phosphorylation (OXPHOS) occurred in normal proliferating hepatocytes displaying Nrf2 activation. Genetic deletion of Nrf2 blunted LN-induced PPP activation and suppressed hepatocyte proliferation. Moreover, Nrf2 activation and following metabolic reprogramming did not occur when hepatocyte proliferation was induced by PH or T3. CONCLUSION: Many metabolic changes in cancer cells are shared by proliferating normal hepatocytes in response to a hostile environment. Nrf2 activation is essential for bridging metabolic changes with crucial components of cancer metabolic reprogramming including the activation of oxidative PPP. Our study demonstrates that matured hepatocytes exposed to LN undergo a cancer-like metabolic reprogramming and offers a rapid and useful in vivo model to study the molecular alterations underpinning the differences/similarities of metabolic changes in normal and neoplastic hepatocytes.

    BACKGROUND: Birth weight, as a measure of intrauterine growth, is commonly used in epidemiological studies and is reported to be associated with adult lung function. However, findings regarding this association in previous studies have been inconsistent. Furthermore, no studies have reported associations stratified by age or smoking status, or adjusted for eosinophil count or other parameters related to type 2 airway inflammation. METHODS: This cross-sectional study included 2632 men and 7237 women aged ≥20 years living in Miyagi Prefecture, Japan. Lung function was assessed based on spirometry. Birth weight data were obtained through a questionnaire survey. Analysis of covariance was used to evaluate the associations between birth weight and lung function, adjusting for potential confounders. Stratified analyses by age and smoking status were also conducted, together with a sub-analysis for low birth-weight participants. RESULTS: Birth weight was positively associated with forced expiratory volume in 1 s (FEV1) for both sexes and with vital capacity in women, after adjusting for height, age, smoking status, and parameters related to type 2 airway inflammation. The stratified analysis for smoking status revealed associations in never-smokers and ex-smokers. When stratified by age, the associations were confirmed in middle-aged participants. The effect of smoking status on the FEV1 of low birth-weight participants was not significant. CONCLUSIONS: Our analysis of a large, Japanese adult population showed that birth weight was independently and positively associated with adult lung function, even after adjustment for age, height, smoking status, and parameters related to type 2 airway inflammation.

    1,2-Dichloropropane (1,2-DCP) is recognized as the causative chemical of occupational cholangiocarcinoma in printing workers in Japan. However, the cellular and molecular mechanisms of 1,2-DCP-induced carcinogenesis remains elusive. The present study investigated cellular proliferation, DNA damage, apoptosis and expression of antioxidant and proinflammatory genes in the liver of mice exposed daily to 1,2-DCP for 5 weeks, and the role of Nrf2 in these responses. Wild-type and Nrf2-knockout (Nrf2-/-) mice were administered 1,2-DCP by gastric gavage, and then the livers were collected for analysis. Immunohistochemistry for BrdU or KI67 and TUNEL assay revealed that exposure to 1,2-DCP dose-dependently increased proliferative cholangiocytes, while decreased apoptotic cholangiocytes in wild-type mice but not in Nrf2-/- mice. Western blot and quantitative real time PCR showed that exposure to 1,2-DCP increased the levels of DNA double-strand break marker γ-H2AX and mRNA expression levels of NQO1, xCT, GSTM1, and G6PD in the livers of wild-type mice in a dose-dependent manner, but no such changes were noted in Nrf2-/- mice. 1,2-DCP increased glutathione levels in the liver of both the wild-type and Nrf2-/- mice, suggesting that a Nrf2-independent mechanism contributes to 1,2-DCP-induced increase in glutathione level. In conclusion, the study demonstrated that exposure to 1,2-DCP induced proliferation but reduced apoptosis in cholangiocytes, and induced double-strand DNA breaks and upregulation of antioxidant genes in the liver in an Nrf2-dependent manner. The study suggests a role of Nrf2 in 1,2-DCP-induced cell proliferation, antiapoptotic effect and DNA damage which are recognized as key characteristics of carcinogens.

    Introduction Perinatal women tend to have difficulties with sleep along with autonomic characteristics. This study aimed to identify a machine learning algorithm capable of achieving high accuracy in predicting sleep–wake conditions and differentiating between the wake conditions before and after sleep during pregnancy based on heart rate variability (HRV). Methods Nine HRV indicators (features) and sleep–wake conditions of 154 pregnant women were measured for 1 week, from the 23rd to the 32nd weeks of pregnancy. Ten machine learning and three deep learning methods were applied to predict three types of sleep–wake conditions (wake, shallow sleep, and deep sleep). In addition, the prediction of four conditions, in which the wake conditions before and after sleep were differentiated—shallow sleep, deep sleep, and the two types of wake conditions—was also tested. Results and Discussion In the test for predicting three types of sleep–wake conditions, most of the algorithms, except for Naïve Bayes, showed higher areas under the curve (AUCs; 0.82–0.88) and accuracy (0.78–0.81). The test using four types of sleep–wake conditions with differentiation between the wake conditions before and after sleep also resulted in successful prediction by the gated recurrent unit with the highest AUC (0.86) and accuracy (0.79). Among the nine features, seven made major contributions to predicting sleep–wake conditions. Among the seven features, “the number of interval differences of successive RR intervals greater than 50 ms (NN50)” and “the proportion dividing NN50 by the total number of RR intervals (pNN50)” were useful to predict sleep–wake conditions unique to pregnancy. These findings suggest alterations in the vagal tone system specific to pregnancy.

    <h4>Background</h4>Literature data suggest that the activation of the Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway increases glomerular filtration rate (GFR) in patients with type 2 diabetes and chronic kidney disease. However, the mechanisms whereby the Keap1-Nrf2 pathway regulates GFR are unknown. Methods: Various renal physiological parameters were assessed in C57BL/6 mice (WT), Nrf2-deficient mice, and Nrf2-activated Keap1-knockdown mice. Also, these parameters were assessed following the administration of RTA dh404 (CDDO-dhTFEA), a Nrf2 activator.<h4>Results</h4>Pharmacological and genetic Keap1-Nrf2 activation increased renal blood flow (p <0.05), glomerular volume (p <0.05) and GFR (p <0.05), but did not alter the afferent-to-efferent arteriolar diameter ratio or glomerular permeability. Calcium influx into the podocytes through TRPC channels in response to H2O2 was suppressed by Keap1-Nrf2 activation and TRPCs inhibition. Treatment with a TRPC6 and TRPC5 inhibitors increased single-nephron GFR in WT mice.<h4>Conclusion</h4>In conclusion, the Keap1-Nrf2 pathway regulates GFR through changes in ultrafiltration by modulating redox-sensitive intracellular calcium signaling and cellular contractility, mediated through TRPC activity, in glomerular cells, in particular the podocytes.

    Bardoxolone methyl (CDDO-Me) is an oleanane triterpenoid in late-stage clinical development for the treatment of patients with diabetic kidney disease. Preclinical studies in rodents demonstrate the efficacy of triterpenoids against carcinogenesis and other diseases, including renal ischemia-reperfusion injury, hyperoxia-induced acute lung injury, and immune hepatitis. Genetic disruption of Nrf2 abrogates protection by triterpenoids, suggesting that induction of the NRF2 pathway may drive this protection. Herein, we examined the effect of a point mutation (C151S) in KEAP1, a repressor of NRF2 signaling, at cysteine 151 in mouse embryo fibroblasts and mouse liver. Induction of target gene transcripts and enzyme activity by CDDO-Me was lost in C151S mutant fibroblasts compared with wild-type. Protection against menadione toxicity was also nullified in the mutant fibroblasts. In mouse liver, CDDO-Me evoked the nuclear translocation of NRF2, followed by increased transcript and activity levels of a prototypic target gene, Nqo1, in wild-type, but not C151S mutant, mice. To test the role of KEAP1 Cys151 in governing the broader pharmacodynamic action of CDDO-Me, wild-type and C151S mutant mice were challenged with concanavalin A to induce immune hepatitis. Strong protection was seen in wild-type but not C151S mutant mice. RNA-seq analysis of mouse liver from wild-type, C151S mutant, and Nrf2-knockout mice revealed a vigorous response of the NRF2 transcriptome in wild-type, but in neither C151S mutant nor Nrf2-knockout, mice. Activation of "off-target" pathways by CDDO were not observed. These data highlight the singular importance of the KEAP1 cysteine 151 sensor for activation of NRF2 signaling by CDDO-Me. SIGNIFICANCE STATEMENT: KEAP1 serves as a key sensor for induction of the cytoprotective signaling pathway driven by the transcription factor NRF2. Mutation of a single cysteine (C151) in KEAP1 abrogates the induction of NRF2 signaling and its downstream cytoprotective actions in vitro and in vivo by bardoxolone methyl (CDDO-Me), a drug in late-stage clinical development. Further, at these bioeffective concentrations/doses, activation of "off-target" pathways by CDDO-Me are not observed, highlighting the singular importance of NRF2 in its mode of action.

    AIM: Previous studies based on a relatively limited number of subjects have indicated potential associations between plasma cytokine concentrations in perinatal women and postpartum depression (PPD). This report aimed to examine alterations in cytokine levels during pregnancy and after delivery by measuring nine cytokines in prenatal and postnatal plasma samples in a large cohort. METHODS: A nested, case-control study was conducted using plasma samples from 247 women with PPD (Edinburgh Postnatal Depression Scale: EPDS ≥9) and 243 age-matched control (EPDS ≤2) women from among perinatal women who participated in the Tohoku Medical Megabank three-generation cohort. Concentrations of nine plasma cytokines (IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12p40, IL-12p70, IL-13, and TNF-α) in plasma collected at the time of enrollment during pregnancy and one month after delivery were determined using an immunoassay kit. RESULTS: Cross-sectional comparisons of cytokine levels during pregnancy and after delivery indicated that the PPD group maintained significantly lower plasma IL-4 levels during pregnancy and after delivery than the control group, and that plasma IL-4 levels decreased significantly during pregnancy regardless of PPD status. Plasma IL-10 levels were significantly higher during pregnancy than after delivery only among healthy controls, and plasma IL-10 levels were significantly higher in the control group than in the PPD group. Moreover, IFN-γ, IL-6, IL-12p40, and TNF-α levels were significantly lower during pregnancy compared with after delivery regardless of PPD status. CONCLUSIONS AND RELEVANCE: These results suggest a potential protective effect of the anti-inflammatory cytokines IL-4 and IL-10 during pregnancy against the development of PPD.

    The erythroid growth factor erythropoietin (EPO) is mainly produced by the kidneys in adult mammals and induces expansion of erythroid cells and iron use for hemoglobin synthesis. The liver also produces EPO at a lower level than the kidneys. Renal and hepatic EPO production is fundamentally regulated by hypoxia-inducible transcription factors (HIFs) in a hypoxia/anemia-inducible manner. Recently, small compounds that activate HIFs and EPO production in the kidneys by inhibiting HIF-prolyl hydroxylases (HIF-PHIs) have been launched to treat EPO-deficiency anemia in patients suffering from kidney disease. However, the roles of the liver in the HIF-PHI-mediated induction of erythropoiesis and iron mobilization remain controversial. Here, to elucidate the liver contributions to the therapeutic effects of HIF-PHIs, genetically modified mouse lines lacking renal EPO-production ability were analyzed. In the mutant mice, HIF-PHI administration marginally increased plasma EPO concentrations and peripheral erythrocytes by inducing hepatic EPO production. The effects of HIF-PHIs on the mobilization of stored iron and on the suppression of hepatic hepcidin, an inhibitory molecule for iron release from iron-storage cells, were not observed in the mutant mice. These findings demonstrate that adequate induction of EPO mainly in the kidney is essential for achieving the full therapeutic effects of HIF-PHIs, which include hepcidin suppression. The data also show that HIF-PHIs directly induce the expression of duodenal genes related to dietary iron intake. Additionally, hepatic EPO induction is considered to partially contribute to the erythropoietic effects of HIF-PHIs but to be insufficient to compensate for the abundant EPO induction by the kidneys.

    GATA1 is an essential master regulator of erythropoiesis and megakaryopoiesis. Accumulating lines of evidence have shown that dynamic changes in GATA1 gene expression levels during erythropoiesis are crucial for proper erythroid differentiation. Since GATA1 is an X-chromosome gene, GATA1 knockout leads to embryonic lethal dyserythropoiesis in male mice, while heterozygous female mice can survive. In the past decade, it has become clear that germline GATA1 gene mutations leading to structural changes in the GATA1 protein are involved in congenital dyserythropoiesis in males. In contrast, decreased GATA1 expression levels, which cause embryonic lethal dyserythropoiesis in male mice, increase the risk of erythroleukemia development in female mice, while female GATA1-knockout mice do not show substantial phenotypic alterations in erythroid or megakaryocyte lineages. In this review, we summarize the recent progress in elucidating the roles of GATA1 in normal and pathogenetic erythropoiesis and discuss the possible mechanisms of pathogenesis of dyserythropoiesis and erythroleukemia.

    Observational studies suggest that abnormal glucose metabolism and insulin resistance contribute to colorectal cancer; however, the causal association remains unknown, particularly in Asian populations. A two-sample Mendelian randomisation analysis was performed to determine the causal association between genetic variants associated with elevated fasting glucose, haemoglobin A1c (HbA1c), and fasting C-peptide and colorectal cancer risk. In the single nucleotide polymorphism (SNP)-exposure analysis, we meta-analysed study-level genome-wide associations of fasting glucose (~ 17,289 individuals), HbA1c (~ 52,802 individuals), and fasting C-peptide (1,666 individuals) levels from the Japanese Consortium of Genetic Epidemiology studies. The odds ratios of colorectal cancer were 1.01 (95% confidence interval [CI], 0.99-1.04, P = 0.34) for fasting glucose (per 1 mg/dL increment), 1.02 (95% CI, 0.60-1.73, P = 0.95) for HbA1c (per 1% increment), and 1.47 (95% CI, 0.97-2.24, P = 0.06) for fasting C-peptide (per 1 log increment). Sensitivity analyses, including Mendelian randomisation-Egger and weighted-median approaches, revealed no significant association between glycaemic characteristics and colorectal cancer (P > 0.20). In this study, genetically predicted glycaemic characteristics were not significantly related to colorectal cancer risk. The potential association between insulin resistance and colorectal cancer should be validated in further studies.

    PURPOSE: To investigate the prevalence, associated factors, and inter-eye differences of myopia and astigmatism in an adult Japanese population-based cohort. METHODS: A total of 4282 participants from the Tohoku Medical Megabank Organization Eye Study (ToMMo Eye Study) underwent comprehensive ocular examinations as well as extensive physiological tests and a lifestyle questionnaire. The spherical equivalent (SE) and cylinder power were obtained as refractive parameters. The age- and gender-stratified prevalences of high myopia (SE < -5D), myopia (SE < -0.5D), hyperopia (SE > 0.5D), astigmatism (cylinder power < -0.5D), and anisometropia (SE difference >1D) were calculated. Multivariable analyses were performed to identify associated factors for refractive error (RE). Distribution and associated factors of the inter-eye difference in RE were also investigated. RESULTS: The age-adjusted prevalence of high myopia, myopia, hyperopia, astigmatism, and anisometropia was 15.9%, 63.5%, 14.7%, 51.1%, and 14.7%, respectively. Both myopia and high myopia were more prevalent in the younger age group, while astigmatism was more prevalent in the older age group. Age, education, blood pressure, intraocular pressure, and corneal thickness are significantly associated with myopic refraction. Age, gender, intraocular pressure, and corneal thickness are correlated with astigmatism. Older age was associated with against-the-rule astigmatism. Older age, myopia, and longer education showed a significant correlation with large inter-eye differences in SERE. CONCLUSIONS: This study demonstrated the high prevalence of myopia in young Japanese, which may be caused by a generational shift. This study also confirmed the influence of age and education on both the prevalence and inter-eye differences of RE.

    Abstract Atypical hemolytic uremic syndrome (aHUS) is a rare complement-mediated disease that manifests as the triad of thrombotic microangiopathy. We identified two aHUS patients with neither anti-complement factor H (CFH) antibodies nor causative variants of seven aHUS-related genes (CFH, CFI, CFB, C3, MCP, THBD, and DGKE); however, their plasma showed increased levels of hemolysis by hemolytic assay, which strongly suggests CFH-related abnormalities. Using a copy number variation (CNV) analysis of the CFH/CFHR gene cluster, we identified CFH-CFHR1 hybrid genes in these patients. We verified the absence of aHUS-related abnormal CNVs of the CFH gene in control genomes of 2036 individuals in the general population, which suggests that pathogenicity is related to these hybrid genes. Our study emphasizes that, for patients suspected of having aHUS, it is important to perform an integrated analysis based on a clinical examination, functional analysis, and detailed genetic investigation.

    Olanzapine is widely used as a treatment for schizophrenia and other psychiatric disorders. Its metabolic side effects, including weight gain and hyperglycemia, are a clinical problem; however, their full mechanism is not yet clearly understood. Recently, it was reported that the accumulation of oxidative stress in the hypothalamus may cause obesity and diabetes mellitus. Epidemiologically, metabolic side effects are known to be more likely to occur in women. In the present study, we investigated and tested the hypothesis that olanzapine induces oxidative stress in the hypothalamus and induces metabolic side effects. We also examined its association with sex differences. Olanzapine was administered intraperitoneally to male and female C57BL/6 mice, and the expression levels of oxidative stress-responsible genes in the hypothalamus and cerebral cortex were measured by qRT-PCR. In addition, olanzapine was administered intraperitoneally to C57BL/6 and Nrf2 KO mice, and the expression level of total glutathione was measured. Gene expressions induced by the Keap1-Nrf2-regulated system showed different responses to olanzapine for each gene. Under the conditions of this experiment, cystine-glutamate transporter was decreased although heme oxygenase-1 and γ-glutamylcysteine synthetase were increased. It was also clear that these responses were not hypothalamus-specific. Long-term feeding with olanzapine suppressed weight gain in males but not females. No glucose intolerance was observed at 13 weeks of administration. Furthermore, deaths occurred only in females. In conclusion, this study failed to provide evidence that olanzapine induces oxidative stress in a hypothalamic-specific manner. Instead, sex differences were observed in response to long-term and high-dose olanzapine administration, suggesting that individual susceptibility to olanzapine toxicity occurred in female mice.

    A system for inputting and storing family information, named “BirThree Enrollment,” was developed to promote a birth and three-generation cohort study (BirThree Cohort Study). In this cohort study, it was necessary to satisfy many operational demands while constantly overwriting and changing input information. Complex kinship information must be quickly and accurately inputed and corrected, and information on those families not yet recruited must be retrieved. For these purposes, many devices are needed, from an input interface to the internal data structure. In the field of genetic statistics, a simple standard expressive form (describe father-child relation and mother-child relation) is used for describing family structure. However, this form doesn't have sufficient information. So we developed a new form in conducting the BirThree Cohort Study. Hence, we expanded the data structure, and constructed the Input control system. Family pedigree information is stored along with initial clinical information, and this enabled the input of all self-reported information to the data base. Operators are able to input this family information before the day is out. As a result, when recruitment is completed, family information will be completed concurrently. Therefore, operators can immediately know certain person's family structure. In this model data correction was improved dramatically, and the system was operated successfully. This study is the first report of the method for storing three generations of family data.

    Abstract Background Genetic variants within nearly 1000 loci are known to contribute to modulation of blood lipid levels. However, the biological pathways underlying these associations are frequently unknown, limiting understanding of these findings and hindering downstream translational efforts such as drug target discovery. Results To expand our understanding of the underlying biological pathways and mechanisms controlling blood lipid levels, we leverage a large multi-ancestry meta-analysis (N = 1,654,960) of blood lipids to prioritize putative causal genes for 2286 lipid associations using six gene prediction approaches. Using phenome-wide association (PheWAS) scans, we identify relationships of genetically predicted lipid levels to other diseases and conditions. We confirm known pleiotropic associations with cardiovascular phenotypes and determine novel associations, notably with cholelithiasis risk. We perform sex-stratified GWAS meta-analysis of lipid levels and show that 3–5% of autosomal lipid-associated loci demonstrate sex-biased effects. Finally, we report 21 novel lipid loci identified on the X chromosome. Many of the sex-biased autosomal and X chromosome lipid loci show pleiotropic associations with sex hormones, emphasizing the role of hormone regulation in lipid metabolism. Conclusions Taken together, our findings provide insights into the biological mechanisms through which associated variants lead to altered lipid levels and potentially cardiovascular disease risk.

    INTRODUCTION: Paget's disease of bone (PDB) is a skeletal disorder characterized by disorganized bone remodeling due to abnormal osteoclasts. Tumor necrosis factor receptor superfamily member 11A (TNFRSF11A) gene encodes the receptor activator of nuclear factor kappa B (RANK), which has a critical role in osteoclast function. There are five types of rare PDB and related osteolytic disorders due to TNFRSF11A tandem duplication variants so far, including familial expansile osteolysis (84dup18), expansile skeletal hyperphosphatasia (84dup15), early-onset familial PDB (77dup27), juvenile PDB (87dup15), and panostotic expansile bone disease (90dup12). MATERIALS AND METHODS: We reviewed a Japanese family with PDB, and performed whole-genome sequencing to identify a causative variant. RESULTS: This family had bone symptoms, hyperphosphatasia, hearing loss, tooth loss, and ocular manifestations such as angioid streaks or early-onset glaucoma. We identified a novel duplication variant of TNFRSF11A (72dup27). Angioid streaks were recognized in Juvenile Paget's disease due to loss-of-function variants in the gene TNFRSF11B, and thought to be specific for this disease. However, the novel recognition of angioid streaks in our family raised the possibility of occurrence even in bone disorders due to TNFRSF11A duplication variants and the association of RANKL-RANK signal pathway as the pathogenesis. Glaucoma has conversely not been reported in any case of Paget's disease. It is not certain whether glaucoma is coincidental or specific for PDB with 72dup27. CONCLUSION: Our new findings might suggest a broad spectrum of phenotypes in bone disorders with TNFRSF11A duplication variants.

    Abstract Several basic leucine zipper (bZIP) transcription factors have accessory motifs in their DNA-binding domains, such as the CNC motif of CNC family or the EHR motif of small Maf (sMaf) proteins. CNC family proteins heterodimerize with sMaf proteins to recognize CNC–sMaf binding DNA elements (CsMBEs) in competition with sMaf homodimers, but the functional role of the CNC motif remains elusive. In this study, we report the crystal structures of Nrf2/NFE2L2, a CNC family protein regulating anti-stress transcriptional responses, in a complex with MafG and CsMBE. The CNC motif restricts the conformations of crucial Arg residues in the basic region, which form extensive contact with the DNA backbone phosphates. Accordingly, the Nrf2–MafG heterodimer has approximately a 200-fold stronger affinity for CsMBE than canonical bZIP proteins, such as AP-1 proteins. The high DNA affinity of the CNC–sMaf heterodimer may allow it to compete with the sMaf homodimer on target genes without being perturbed by other low-affinity bZIP proteins with similar sequence specificity.

    The Tohoku Medical Megabank Project (TMM) has been conducting a birth and three-generation cohort study (the BirThree Cohort Study). We recruited 73,529 pregnant women and their family members for this cohort study, which included 23,143 newborns and 9,459 of their siblings. We designed and are in the process of conducting three-step health assessments for each newborn at approximately ages of 5, 10 and 16. These health assessments are administered at seven community support centers. Trained genome medical research coordinators conduct physical examinations of and collect biological specimens from each participant. The Sendai Children's Health Square has been established as the headquarters for these child health assessments and is utilized to accumulate knowledge that can facilitate the proper practice of child health assessments. We designed all the relevant health assessments facilities to allow parents and their children to participate in the health assessments concomitantly. Our centers serve as places where child participants and their parents can feel at ease as a result of the implementation of safety measures and child hospitality measures. The TMM BirThree Cohort Study is in the process of conducting strategically detailed health assessments and genome analysis, which can facilitate studies concerning the gene-environment interactions relevant to noncommunicable diseases. Through these operations, our study allows for a significant depth of data to be collected in terms of the number of biospecimens under study and the comprehensiveness of both basic and clinical data alongside relevant family information.

    Chronic kidney disease (CKD) is a syndrome characterized by a gradual loss of kidney function with decreased estimated glomerular filtration rate (eGFR), which may be accompanied by an increase in the urine albumin-to-creatinine ratio (UACR). Although trans-ethnic genome-wide association studies (GWASs) have been conducted for kidney-related traits, there have been few analyses in the Japanese population, especially for the UACR trait. In this study, we conducted a GWAS to identify loci related to multiple kidney-related traits in Japanese individuals. First, to detect loci associated with CKD, eGFR, and UACR, we performed separate GWASs with the following two datasets: 475 cases of CKD diagnosed at seven university hospitals and 3471 healthy subjects (dataset 1) and 3664 cases of CKD-suspected individuals with eGFR <60 ml/min/1.73 m2 or urinary protein ≥ 1+ and 5952 healthy subjects (dataset 2). Second, we performed a meta-analysis between these two datasets and detected the following associated loci: 10 loci for CKD, 9 loci for eGFR, and 22 loci for UACR. Among the loci detected, 22 have never been reported previously. Half of the significant loci for CKD were shared with those for eGFR, whereas most of the loci associated with UACR were different from those associated with CKD or eGFR. The GWAS of the Japanese population identified novel genetic components that were not previously detected. The results also suggest that the group primarily characterized by increased UACR possessed genetically different features from the group characterized by decreased eGFR.

    Glaucoma is one of the most common causes of blindness worldwide. It is thought to be a multifactorial disease with underlying mechanisms that include mitochondrial dysfunction and oxidative stress. Here, we used NF-E2 related factor 2 (Nrf2) knockout (KO) mice, which are vulnerable to oxidative stress, to examine a neuroprotective effect against oxidative stress due to rotenone, a mitochondrial complex I inhibitor. Wild-type (WT) and Nrf2 KO mice received an oral solution of rotenone for 30 days. We then extracted the retinas and performed immunohistochemistry and quantitative RT-PCR. We also prepared a primary Müller cell culture of samples from each mouse, added 30 μM rotenone, and then measured cell viability, cytotoxicity and CellRox absorbance. We also examined gene expression. We found a significant increase in the number of 8-OHdG-positive retinal ganglion cells (RGCs) after rotenone administration in both the WT and Nrf2 KO mice. There was no difference in the number of RNA-binding protein with multiple splicing (RBPMS)-positive RGCs in the WT and Nrf2 KO mice, but Nrf2 KO mice that were given rotenone had significantly less retinal gene expression of RBPMS than Nrf2 KO mice given a control. Moreover, there was significantly higher mRNA gene expression of vimentin and glial fibrillary acidic protein (GFAP) in Nrf2 KO mice that received rotenone than WT mice that received rotenone. A statistical analysis of the in vitro experiment showed that cell viability was lower, cytotoxicity was higher, and oxidative stress was higher in the Müller cells of the Nrf2 KO mice than the WT mice. Finally, brain-derived neurotrophic factor (BDNF) and basic fibroblast growth factor (bFGF) were significantly higher in the Müller cells of the Nrf2 KO mice than the WT mice. These findings suggest that in Nrf2 KO mice under oxidative stress caused by rotenone, temporary neurotrophic factors are secreted from the Müller cells, conferring neuroprotection in these cells.

    Cells are often exposed to exogenous and endogenous redox disturbances and exert their protective mechanisms in response to stimuli. The KEAP1-NRF2 system plays pivotal roles in counteracting oxidative damage. Due to the transient nature of NRF2 activation, the identification of cells in which NRF2 is activated in response to systemic stimuli is sometimes not easy. To examine the electrophilic stress response at a single-cell resolution, we aimed to develop a new reporter mouse in this study. A cell-tracing strategy exploiting Cre recombinase-mediated activation of a reporter gene was chosen for stable detection of reporter expression instead of real-time monitoring of the cellular response. We established a transgenic mouse line expressing the Neh2-Cre recombinase fusion protein. As Neh2 is an amino-terminal domain of NRF2 that serves as a degron and mediates KEAP1-dependent degradation and electrophile-inducible stabilization, Neh2-Cre was expected to be activated in response to electrophiles. The Neh2-Cre transgenic mouse was crossed with the ROSA26-loxP-stop-loxP-tdTomato reporter mouse (ROSA-LSL-tdTomato mouse). The compound mutant reporter mice exhibited accumulation of tdTomato-positive cells in various organs after repeated administration of CDDO-Im, one of the NRF2-inducing electrophiles. The mice were also successfully used for the detection of cells that experienced a cisplatin-induced electrophilic stress response.

    BACKGROUND: Zinc oxide nanoparticles (ZnO-NPs) are currently employed in various products such as rubber, paint, and cosmetics. Our group reported recently that Nrf2 protein provides protection against pulmonary inflammation induced by ZnO-NPs in male mice. The current study investigated the effect of Nrf2 deletion on the lung inflammatory response in female mice exposed to ZnO-NPs. METHODS: An equal number of female Nrf2-/- mice and female Nrf2+/+ mice (24 each) were allocated into three equal groups, and each was exposed to ZnO-NPs at either 0, 10 or 30 µg ZnO-NPs/mouse through pharyngeal aspiration. Bronchoalveolar lavage fluid (BALF) and lungs were examined 14 days later to determine the number of inflammatory cells, the protein level, and for scoring inflammation histopathologically. The mRNA levels of Nrf2-dependent antioxidant enzymes and proinflammatory cytokine in lung tissue were also measured. RESULTS: Exposure to ZnO-NPs increased all types of BALF cells and lung inflammation scores in both of female Nrf2-null (Nrf2-/-) and wild-type (Nrf2+/+) mice, and Nrf2 deletion enhanced ZnO-NPs-induced increase in the number of eosinophils in BALF. Exposure to ZnO-NPs dose-dependently increased the level of oxidized glutathione (GSSG), and mRNA levels of proinflammatory cytokines/chemokines; KC, MIP-2, IL-6, IL-1β and MCP-1 only in wild-type mice. Nrf2 deletion decreased total glutathione levels and basal mRNA levels of SOD1 and NQO1, and increased the basal mRNA level of above proinflammatory cytokines/chemokines. Nrf2 deletion enhanced ZnO-NPs-induced downregulation of GcLc, GR and TGF-β and upregulation of HO-1 and TNF-α. Taken together with our previous results in male mice, our results showed a lower susceptibility of females to lung tissue inflammation, relative to males, irrespective of Nrf2 deletion, and that enhancement of ZnO-NPs-induced upregulation of HO-1 and TNF-α and downregulation of GcLc, GR and TGF-β by deletion of Nrf2 is specific to female mice. CONCLUSION: We conclude that Nrf2 provides protection in female mice against increase in BALF eosinophils, probably through down-regulation of proinflammatory cytokines/chemokines and upregulation of oxidative stress-related genes. The study also suggests lower susceptibility to lung tissue inflammation in female mice relative to their male counterparts and the synergistic effects of Nrf2 and exposure to ZnO-NPs on mRNA expression of GcLc, GR, HO-1, TGF-β or TNF-α in female mice.

    Oxidative stress is an essential component in the progression of diabetic kidney disease (DKD), and the transcription factor NF-E2-related factor-2 (Nrf2) plays critical roles in protecting the body against oxidative stress. To clarify the roles of Nrf2 in protecting against DKD, in this study we prepared compound mutant mice with diabetes and loss of antioxidative defense. Specifically, we prepared compound Ins2Akita/+ (Akita) and Nrf2 knockout (Akita::Nrf2-/-) or Akita and Nrf2 induction (Akita::Keap1FA/FA) mutant mice. Eighteen-week-old Akita::Nrf2-/- mice showed more severe diabetic symptoms than Akita mice. In the Akita::Nrf2-/- mouse kidneys, the glomeruli showed distended capillary loops, suggesting enhanced mesangiolysis. Distal tubules showed dilation and an increase in 8-hydroxydeoxyguanosine-positive staining. In the Akita::Nrf2-/- mouse kidneys, the expression of glutathione (GSH) synthesis-related genes was decreased, and the actual GSH level was decreased in matrix-assisted laser desorption/ionization mass spectrometry imaging analysis. Akita::Nrf2-/- mice exhibited severe inflammation and enhancement of infiltrated macrophages in the kidney. To further examine the progression of DKD, we compared forty-week-old Akita mouse kidney compounds with Nrf2-knockout or Nrf2 mildly induced (Akita::Keap1FA/FA) mice. Nrf2-knockout Akita (Akita::Nrf2-/-) mice displayed severe medullary cast formation, but the formation was ameliorated in Akita::Keap1FA/FA mice. Moreover, in Akita::Keap1FA/FA mice, tubule injury and inflammation-related gene expression were significantly suppressed, which was evident in Akita::Nrf2-/- mouse kidneys. These results demonstrate that Nrf2 contributes to the protection of the kidneys against DKD by suppressing oxidative stress and inflammation.

    The KEAP1-NRF2 pathway regulates the main inducible cellular response to oxidative and electrophilic stresses. Activating mutations in the KEAP1-NRF2 pathway occur commonly in human cancer, where they contribute to the formation of aggressive tumours that are associated with a poor prognosis for patients. An important clinical feature of these tumours is their defiance to all current anti-cancer treatment regimens, highlighting the need for the development of new therapeutic strategies to target NRF2-activated cancers. In this review, we discuss the mechanisms through which acquired NRF2 hyperactivation can result in resistance of tumours to immune checkpoint inhibitor therapies in addition to classical chemotherapeutics, and propose with examples that using a synthetic lethal strategy mediated by NRF2-target gene-dependent bioactivation of prodrugs represents a promising strategy to specifically enhance toxicity to heretofore untreatable NRF2-hyperactivated human tumours.

    Disorders of sex development (DSD) comprises a congenital condition in which chromosomal, gonadal, or anatomical sex development is atypical. In this study, we screened for pathogenic variants in 32 genes associated with DSDs and central causes of hypogonadism (CHG) in a whole-genome reference panel including 8380 Japanese individuals constructed by Tohoku Medical Megabank Organization. Candidate pathogenic (P) or likely pathogenic (LP) variants were extracted from the ClinVar, InterVar, and Human Gene Mutation databases. Ninety-one candidate pathological variants were found in 25 genes; 28 novel candidate variants were identified. Nearly 1 in 40 (either ClinVar or InterVar P or LP) to 157 (both ClinVar and InterVar P or LP) individuals were found to be carriers of recessive DSD and CHG alleles. In these data, genes implicated in gonadal dysfunction did not show loss-of-function variants, with a relatively high tendency of intolerance for haploinsufficiency based on pLI and Episcore, both of which can be used for estimating haploinsufficiency. We report the types and frequencies of causative variants for DSD and CHG in the general Japanese population. This study furthers our understanding of the genetic causes and helps to refine genetic counseling of DSD and CHG.

    NRF2 (nuclear factor erythroid 2-related factor 2) is a transcription factor that regulates the expression of many cytoprotective genes. NRF2 activation is mainly regulated by KEAP1 (kelch-like ECH-associated protein 1) through ubiquitination and proteasome degradation. Esophageal cancer is classified histologically into two major types: esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). ESCC harbors more genetic alterations in the KEAP-NRF2 system than EAC does, which results in NRF2 activation in these cancers. NRF2-addicted ESCC exhibits increased malignancy and acquisition of resistance to chemoradiotherapy. Therefore, it has been recognized that the development of drugs targeting the KEAP1-NRF2 system based on the molecular dissection of NRF2 function is important and urgent for the treatment of ESCC, along with efficient clinical screening for NRF2-addicted ESCC patients. Recently, the fate of NRF2-activated cells in esophageal tissues, which was under the influence of strong cell competition, and its relationship to the pathogenesis of ESCC, was clarified. In this review, we will summarize the current knowledge of the KEAP1-NRF2 system and the treatment of ESCC. We propose three main strategies for the treatment of NRF2-addicted cancer: (1) NRF2 inhibitors, (2) synthetic lethal drugs for NRF2-addicted cancers, and (3) NRF2 inducers of the host defense system.

    BACKGROUND: Recent advances in human genome research have provided evidence for genotype-phenotype associations, pathogenicity, and clinical actionability of variants and genomic risk prediction of disease. However, the return of individual genomic results to healthy individuals is fraught with ethical and practical complexity. METHODS: Individual genomic results were returned to BRCA1/2 pathogenic variant (PV) carriers of the Tohoku Medical Megabank cohort study participants with an information on hereditary breast and ovarian cancer syndrome (HBOC). One hundred and eighty participants, including 9 BRCA1/2 PV carriers, were asked about their willingness to receive individual genomic results, without revealing the gene name and related disorders, prior to the study. Of the 142 participants who responded, 103 showed willingness to know their genomic information. Each of the six BRCA1/2 PV carriers who consented to participate in the study received information about HBOC in person and underwent validation testing with blood resampling. RESULTS: All participants were in their 60s or 70s; of the four females and two males, two had a history of breast cancer and five had a family history of HBOC-related cancers. All participants appreciated the information, without remarkable negative psychological impact of the return, and intended to undergo clinical risk surveillance. Five participants were accompanied by family members while receiving the results, and three first-degree female relatives wished to undergo genomic testing at the hospital. CONCLUSIONS: Our results suggest that returning actionable genomic information to participants in a population-based genome cohort study is beneficial for preventing or providing early-stage intervention for associated diseases.

    PURPOSE: A meta-analysis suggests a relationship between abnormal glucose metabolism and primary open-angle glaucoma (POAG); however, the causal association between them remains controversial. We therefore conducted a Mendelian randomization (MR) study to assess the causal association between genetically predicted glycemic traits and the risk of POAG. DESIGN: Two-sample MR design. METHODS: We examined the genetically predicted measures of fasting glucose, hemoglobin A1c (HbA1c), and fasting C-peptide, in relation to POAG. For the single nucleotide polymorphism (SNP)-exposure analyses, we meta-analyzed the study-level genome-wide associations of fasting glucose levels (n = 17,289; n of SNPs = 34), HbA1c (n = 52,802; n of SNPs = 43), and fasting C-peptide levels (n=1666; n of SNPs = 17) from the Japanese Consortium of Genetic Epidemiology studies. We used summary statistics from the BioBank Japan projects (n = 3980 POAG cases and 18,815 controls) for the SNP-outcome association. RESULTS: We observed no association of genetically predicted HbA1c and fasting C-peptide with POAG. The MR inverse-variance-weighted (IVW) odds ratios (ORs) were 1.44 (95% confidence interval [CI], 0.78-2.65; P = .25) for HbA1c (per 1% increment) and 0.92 (95% CI, 0.56-1.53; P = .76) for fasting C-peptide (per 2-fold increment). A significant association between fasting glucose (per 10 mg/dL-increment) and POAG was observed according to the MR IVW analysis (OR = 1.48 [95% CI, 1.10-1.79, P = .009]); however, sensitivity analyses, including MR-Egger and weighted-median methods, did not support this association (P > .10). CONCLUSIONS: We did not observe strong evidence to support the association between genetically predicted glycemic traits and POAG in the Japanese population.

    Long-read sequencing technology enable better characterization of structural variants (SVs). To adapt the technology to population-scale analyses, one critical issue is to obtain sufficient amount of high-molecular-weight genomic DNA. Here, we propose utilizing activated T lymphocytes, which can be established efficiently in a biobank to stably supply high-grade genomic DNA sufficiently. We conducted nanopore sequencing of 333 individuals constituting 111 trios with high-coverage long-read sequencing data (depth 22.2x, N50 of 25.8 kb) and identified 74,201 SVs. Our trio-based analysis revealed that more than 95% of the SVs were concordant with Mendelian inheritance. We also identified SVs associated with clinical phenotypes, all of which appear to be stably transmitted from parents to offspring. Our data provide a catalog of SVs in the general Japanese population, and the applied approach using the activated T-lymphocyte resource will contribute to biobank-based human genetic studies focusing on SVs at the population scale.

    BACKGROUND & AIMS: NF-E2-related factor 2 (NRF2) is a transcription factor that regulates cytoprotective gene expression in response to oxidative and electrophilic stresses. NRF2 activity is mainly controlled by Kelch-like ECH-associated protein 1 (KEAP1). Constitutive NRF2 activation by NRF2 mutations or KEAP1 dysfunction results in a poor prognosis for esophageal squamous cell carcinoma (ESCC) through the activation of cytoprotective functions. However, the detailed contributions of NRF2 to ESCC initiation or promotion have not been clarified. Here, we investigated the fate of NRF2-activated cells in the esophageal epithelium. METHODS: We generated tamoxifen-inducible, squamous epithelium-specific Keap1 conditional knockout (Keap1-cKO) mice in which NRF2 was inducibly activated in a subset of cells at the adult stage. Histological, quantitative reverse-transcription polymerase chain reaction (qRT‒PCR), single-cell RNA-sequencing (RNA-seq) and carcinogen experiments were conducted to analyze the Keap1-cKO esophagus. RESULTS: KEAP1-deleted/NRF2-activated cells and cells with normal NRF2 expression (KEAP1-normal cells) coexisted in the Keap1-cKO esophageal epithelium in approximately equal numbers, and NRF2-activated cells formed dysplastic lesions. NRF2-activated cells exhibited weaker attachment to the basement membrane and gradually disappeared from the epithelium. In contrast, neighboring KEAP1-normal cells exhibited accelerated proliferation and started dominating the epithelium but accumulated DNA damage that triggered carcinogenesis upon carcinogen exposure. CONCLUSIONS: Constitutive NRF2 activation promotes the selective elimination of epithelial cells via cell competition, but this competition induces DNA damage in neighboring KEAP1-normal cells, which predisposes them to chemical-induced ESCC.

    The associations between blood lipids, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides, and low-density lipoprotein cholesterol (LDL-C), and colorectal cancer risk are controversial. We evaluated potential causal relationships between blood lipids and colorectal cancer risk. Using the baseline data from the Japanese Consortium of Genetic Epidemiology studies, we estimated the single-nucleotide polymorphism (SNP)-exposure associations (n=34,546 for TC, n=50,290 for HDL-C, n=51,307 for triglycerides, and n=30,305 for LDL-C). We also estimated the SNP-outcome associations in another Japanese dataset (n=7,936 colorectal cancer cases and n=38,042 controls). We conducted Mendelian randomization analyses for the association between each blood lipid type and the risk of colorectal cancer using an inverse variance-weighted method. The total variances explained by the selected SNPs in TC (68 SNPs), HDL-C (50 SNPs), log-transformed triglycerides (26 SNPs), and LDL-C (35 SNPs) were 7.0%, 10.0%, 6.2%, and 5.7%, respectively. The odds ratios for colorectal cancer were 1.15 (95% confidence interval 1.01-1.32) per 1 standard deviation (SD) (33.3 mg/dL) increase in TC, 1.11 (0.98-1.26) per 1 SD (15.4 mg/dL) increase in HDL-C, 1.06 (0.90-1.26) per 1 SD (0.5 log-mg/dL) increase in log-transformed triglycerides, and 1.17 (0.91-1.50) per 1 SD (29.6 mg/dL) increase in LDL-C. Sensitivity analyses consistently suggested the positive association between TC and colorectal cancer, whereas results of each lipid component were inconsistent. In conclusion, this large Mendelian randomization study of a Japanese population showed a potentially causal association between high TC and colorectal cancer risk, although the association between each lipid component and colorectal cancer remained inconclusive.

    The transcription factor Nrf2 plays a crucial role in the anti-oxidative stress response, protection of DNA from injury, and DNA repair mechanisms. Nrf2 activity reduces cancer initiation, but how Nrf2 affects whole-genome alterations upon carcinogenic stimulus remains unexplored. Although recent genome-wide analysis using next-generation sequencing revealed landscapes of nucleotide mutations and copy number alterations in various human cancers, genomic changes in murine cancer models have not been thoroughly examined. We elucidated the relationship between Nrf2 expression levels and whole exon mutation patterns using an ethyl-carbamate (urethane)-induced lung carcinogenesis model employing Nrf2-deficient and Keap1-kd mice, the latter of which express high levels of Nrf2. Exome analysis demonstrated that single nucleotide and trinucleotide mutation patterns and the Kras mutational signature differed significantly and were dependent on the expression level of Nrf2. The Nrf2-deficient tumors exhibited fewer copy number alterations relative to the Nrf2-wt and Keap1-kd tumors. The observed trend in genomic alterations likely prevented the Nrf2-deficient tumors from progressing into malignancy. For the first time, we present whole-exome sequencing results for chemically-induced lung tumors in the Nrf2 gain or loss of function mouse models. Our results demonstrate that different Nrf2 expression levels lead to distinct gene mutation patterns that underly different oncogenic mechanisms in each tumor genotype.

    A major challenge of genome-wide association studies (GWASs) is to translate phenotypic associations into biological insights. Here, we integrate a large GWAS on blood lipids involving 1.6 million individuals from five ancestries with a wide array of functional genomic datasets to discover regulatory mechanisms underlying lipid associations. We first prioritize lipid-associated genes with expression quantitative trait locus (eQTL) colocalizations and then add chromatin interaction data to narrow the search for functional genes. Polygenic enrichment analysis across 697 annotations from a host of tissues and cell types confirms the central role of the liver in lipid levels and highlights the selective enrichment of adipose-specific chromatin marks in high-density lipoprotein cholesterol and triglycerides. Overlapping transcription factor (TF) binding sites with lipid-associated loci identifies TFs relevant in lipid biology. In addition, we present an integrative framework to prioritize causal variants at GWAS loci, producing a comprehensive list of candidate causal genes and variants with multiple layers of functional evidence. We highlight two of the prioritized genes, CREBRF and RRBP1, which show convergent evidence across functional datasets supporting their roles in lipid biology.

    Radiation-induced oral mucositis is one of the most common adverse events in radiation therapy for head and neck cancers, but treatments for oral mucositis are limited to palliative and supportive care. New approaches are required to prevent radiation-induced mucositis and to improve treatments. The Keap1-Nrf2 system regulates cytoprotection against oxidative and electrophilic stresses. Nrf2 also regulates keratin layer thickness in mouse tongues. Therefore, we hypothesized that Nrf2 may protect the tongue epithelium against radiation-induced mucositis via elimination of reactive oxygen species and induction of keratin layer thickening. To test this hypothesis, we prepared a system for γ-ray exposure of restricted areas and irradiated the tongues of model mice with Nrf2 and Keap1 loss-of-function. We discovered that loss of Nrf2 expression indeed sensitized the tongue epithelium to radiation-induced ulcer formation with inflammation. Constitutive Nrf2 activation by genetic Keap1 knockdown alleviated radiation-induced DNA damage by increasing antioxidation. In agreement with the genetic Nrf2 activation model, the Nrf2 inducer CDDO-Im prevented irradiation damage to the tongue epithelium. These results demonstrate that Nrf2 activation has the potential to prevent the development of radiation-induced mucositis and that Nrf2 inducers are an important therapeutic drug for protection of the upper aerodigestive tract from radiation-induced mucositis.

    Nrf2 activates cytoprotective gene expression, and Nrf2 activity is regulated through at least two protein degradation pathways: the Keap1-mediated and β-TrCP-mediated pathways. To address the relative contributions of these pathways, we generated knock-in mouse lines expressing an Nrf2SA mutant that harbored two substitution mutations of serine residues interacting with β-TrCP. The homozygous (Nrf2SA/SA) mice grew normally, with Nrf2 levels comparable to those of wild-type (WT) mice under unstressed conditions. However, when Keap1 activity was suppressed, high levels of Nrf2 accumulated in Nrf2SA/SA macrophages compared with that in WT macrophages. We crossed Nrf2SA/SA mice with mice in which Keap1 was knocked down to two different levels. We found that the Nrf2SA/SA mutation induced higher Nrf2 activity when the Keap1 level was strongly reduced, and these mice showed severe growth retardation. However, activation and growth retardation were not evident when Keap1 was moderately suppressed. These increases in Nrf2 activity induced by the Nrf2SA mutation caused severe hyperplasia and hyperkeratosis in the esophageal epithelium but did not cause abnormalities in the other tissues/organs examined. These results indicate that the β-TrCP-mediated pathway cooperates with the Keap1-mediated pathway to regulate Nrf2 activity, which is apparent when the Keap1-mediated pathway is profoundly suppressed.

    The Keap1-Nrf2 system is the master regulator of the cellular response against oxidative and xenobiotic stresses. Constitutive activation of Nrf2 is frequently observed in various types of cancers. Nrf2 hyperactivation induces metabolic reprogramming in cancer cells, which supports the increased energy demand required for rapid proliferation and confers high-level resistance against anticancer radio/chemotherapy. Hence, Nrf2 inhibition has emerged as an attractive therapeutic strategy to counter such acquired resistance in Nrf2-activated tumors. We previously identified Halofuginone (HF) as a promising Nrf2 inhibitor. In this study, we pursued preclinical characterization of HF and found that while HF markedly reduced the viability of cancer cells, it also caused severe hematopoietic and immune cell suppression in a dose-dependent manner. Hence, to overcome this toxicity, we decided to employ a nanomedicine approach to HF. We found that encapsulation of HF into a polymeric micelle (HF micelle; HFm) largely relieved the systemic toxicity exhibited by free HF while maintaining the tumor-suppressive properties of HF. LC-MS/MS analysis revealed that the reduction in the magnitude of adverse effects was the result of the ability to release HF from the HFm core in a slow and sustained manner. These results thus support the contention that HFm will potentially counteract Nrf2-activated cancers in the clinical settings.

    Although narrowband UVB (NB-UVB) has replaced broadband UVB (BB-UVB) because of its greater effectiveness in dermatological phototherapy, it is twice as carcinogenic as BB-UVB at an equivalent inflammatory dose. To clarify the basis of the different genotoxicities, we comparatively evaluated the mutagenicities in mouse skin of the two UVB types along with their efficiencies in the formation of cyclobutane pyrimidine dimer (CPD), which is a major mutagenic DNA photolesion specifically produced by UVR. We found that the mutagenicity averaged per single molecule of CPD was 2.5- and 1.8-fold higher in NB-UVB-exposed epidermis and dermis, respectively, which indicates that NB-UVB is more mutagenic for the skin than BB-UVB at doses producing an equimolar amount of CPD. Analysis of effective wavelengths for UV photolesion formation with each UVB source revealed a remarkable difference in the peak effective wavelengths for CPD formation: 15 nm longer for NB-UVB in the epidermis. Although the analysis of mutation profiles showed largely similar UV-specific signatures between the two UVB types, a relatively stronger preference for UVA-specific mutations was observed for NB-UVB. These results suggest that the difference in the effective wavelengths for CPD formation leads to the different mutagenicities and carcinogenicities between the UVB sources.

    'Reactive oxygen species' (ROS) is a generic term that defines a wide variety of oxidant molecules with vastly different properties and biological functions that range from signalling to causing cell damage. Consequently, the description of oxidants needs to be chemically precise to translate research on their biological effects into therapeutic benefit in redox medicine. This Expert Recommendation article pinpoints key issues associated with identifying the physiological roles of oxidants, focusing on H2O2 and O2.-. The generic term ROS should not be used to describe specific molecular agents. We also advocate for greater precision in measurement of H2O2, O2.- and other oxidants, along with more specific identification of their signalling targets. Future work should also consider inter-organellar communication and the interactions of redox-sensitive signalling targets within organs and whole organisms, including the contribution of environmental exposures. To achieve these goals, development of tools that enable site-specific and real-time detection and quantification of individual oxidants in cells and model organisms are needed. We also stress that physiological O2 levels should be maintained in cell culture to better mimic in vivo redox reactions associated with specific cell types. Use of precise definitions and analytical tools will help harmonize research among the many scientific disciplines working on the common goal of understanding redox biology.

    Abstract Accumulating lines of clinical evidence support the emerging hypothesis that loss-of-function mutations of GATA2 cause inherited hematopoietic diseases, including Emberger syndrome; dendritic cell, monocyte B and NK lymphoid (DCML) deficiency; and MonoMAC syndrome. Here, we show that mice heterozygous for an arginine-to-tryptophan substitution mutation in GATA2 (G2R398W/+), which was found in a patient with DCML deficiency, substantially phenocopy human DCML deficiency. Mice heterozygous for the GATA2-null mutation (G2-/+) do not show such phenotypes. The G2R398W protein possesses a decreased DNA-binding affinity but obstructs the function of coexpressed wild-type GATA2 through specific cis-regulatory regions, which contain two GATA motifs in direct-repeat arrangements. In contrast, G2R398W is innocuous in mice containing single GATA motifs. We conclude that the dominant-negative effect of mutant GATA2 on wild-type GATA2 through specific enhancer/silencer of GATA2 target genes perturbs the GATA2 transcriptional network, leading to the development of the DCML-like phenotype. The present mouse model provides an avenue for the understanding of molecular mechanisms underlying the pathogenesis of GATA2-related hematopoietic diseases.

    Introduction: Pharmacogenomic (PGx) testing results provide valuable information on drug selection and appropriate dosing, maximization of efficacy, and minimization of adverse effects. Although the number of large-scale, next-generation-sequencing-based PGx studies has recently increased, little is known about the risks and benefits of returning PGx results to ostensibly healthy individuals in research settings. Methods: Single-nucleotide variants of three actionable PGx genes, namely, MT-RNR1, CYP2C19, and NUDT15, were returned to 161 participants in a population-based Tohoku Medical Megabank project. Informed consent was obtained from the participants after a seminar on the outline of this study. The results were sent by mail alongside sealed information letter intended for clinicians. As an exception, genetic counseling was performed for the MT-RNR1 m.1555A > G variant carriers by a medical geneticist, and consultation with an otolaryngologist was encouraged. Questionnaire surveys (QSs) were conducted five times to evaluate the participants' understanding of the topic, psychological impact, and attitude toward the study. Results: Whereas the majority of participants were unfamiliar with the term PGx, and none had undergone PGx testing before the study, more than 80% of the participants felt that they could acquire basic PGx knowledge sufficient to understand their genomic results and were satisfied with their potential benefit and use in future prescriptions. On the other hand, some felt that the PGx concepts or terminology was difficult to fully understand and suggested that in-person return of the results was desirable. Conclusions: These results collectively suggest possible benefits of returning preemptive PGx information to ostensibly healthy cohort participants in a research setting.

    Members of the cap'n'collar (CNC) family of transcription factors, including Nrf1 and Nrf2, heterodimerize with small Maf (sMaf) proteins (MafF, MafG, and MafK) and regulate target gene expression through CNC-sMaf-binding elements (CsMBEs). We recently developed a unique tethered dimer assessment system combined with small Maf triple-knockout fibroblasts, which enabled the characterization of specific CNC-sMaf heterodimer functions. In this study, we evaluated the molecular function of the tethered Nrf1-MafG (T-N1G) heterodimer. We found that T-N1G activates the expression of proteasome subunit genes, well-known Nrf1 target genes, and binds specifically to CsMBEs in the proximity of these genes. T-N1G was also found to activate genes involved in proteostasis-related pathways, including endoplasmic reticulum-associated degradation, chaperone, and ubiquitin-mediated degradation pathways, indicating that the Nrf1-MafG heterodimer regulates a wide range of proteostatic stress response genes. By taking advantage of this assessment system, we found that Nrf1 has the potential to activate canonical Nrf2 target cytoprotective genes when strongly induced. Our results also revealed that transposable SINE B2 repeats harbor CsMBEs with high frequency and contribute to the target gene diversity of CNC-sMaf transcription factors.

    In a multicellular environment, many different types of cells interact with each other. The KEAP1-NRF2 system defends against electrophilic and oxidative stresses in various types of cells. However, the KEAP1-NRF2 system also regulates the expression of genes involved in cell proliferation and inflammation, indicating that the system plays cell type-specific roles. In this review, we introduce the multifarious roles of the KEAP1-NRF2 system in various types of cells, especially focusing on cancer and inflammatory diseases. Cancer cells frequently hijack the KEAP1-NRF2 system, and NRF2 activation confers cancer cells with a proliferative advantage and therapeutic resistance. In contrast, the activation of NRF2 in immune cells, especially in myeloid cells, suppresses tumor development. In chronic inflammatory diseases, such as sickle cell disease, NRF2 activation in myeloid and endothelial cells represses the expression of proinflammatory cytokine and adherent molecule genes, mitigating inflammation and organ damage. Based on these cell-specific roles played by the KEAP1-NRF2 system, NRF2 inducers have been utilized for the treatment of inflammatory diseases. In addition, the use of NRF2 inducers and/or inhibitors with canonical antineoplastic drugs is an emerging approach to cancer treatment.

    PURPOSE: To elucidate the differences in ocular biometric parameters by generation and gender and to identify axial length (AL)-associated genetic variants in Japanese individuals, we analyzed Tohoku Medical Megabank Organization (ToMMo) Eye Study data. DESIGN: We designed the ToMMo Eye Study, examined AL variations, and conducted genome-wide association studies (GWASs). PARTICIPANTS: In total, 33 483 participants aged > 18 years who were recruited into the community-based cohort (CommCohort) and the birth and three-generation cohort (BirThree Cohort) of the ToMMo Eye Study were examined. METHODS: Each participant was screened with an interview, ophthalmic examinations, and a microarray analysis. The GWASs were performed in 22 379 participants in the CommCohort (discovery stage) and 11 104 participants in the BirThree Cohort (replication stage). We evaluated the associations of single nucleotide polymorphisms (SNPs) with AL using a genome-wide significance threshold (5 × 10-8) in each stage of the study and in the subsequent meta-analysis. MAIN OUTCOME MEASURES: We identified the association of SNPs with AL and distributions of AL in right and left eyes and individuals of different sexes and ages. RESULTS: In the discovery stage, the mean AL of the right eye (23.99 mm) was significantly greater than that of the left eye (23.95 mm). This difference was reproducible across sexes and ages. The GWASs revealed 703 and 215 AL-associated SNPs with genome-wide significance in the discovery and validation stages, respectively, and many of the SNPs in the discovery stage were replicated in the validation stage. Validated SNPs and their associated loci were meta-analyzed for statistical significance (P < 5 × 10-8). This study identified 1478 SNPs spread over 31 loci. Of the 31 loci, 5 are known AL loci, 15 are known refractive-error loci, 4 are known corneal-curvature loci, and 7 loci are newly identified loci that are not known to be associated with AL. Of note, some of them shared functional relationships with previously identified loci. CONCLUSIONS: Our large-scale GWASs exploiting ToMMo Eye Study data identified 31 loci linked to variations in AL, 7 of which are newly reported in this article. The results revealed genetic heterogeneity and similarity in SNPs related to ethnic variations in AL.

    Kidney injury often causes anemia due to a lack of production of the erythroid growth factor erythropoietin (EPO) in the kidneys. Roxadustat is one of the first oral medicines inducing EPO production in patients with renal anemia by activating hypoxia-inducible factors (HIFs), which are activators of EPO gene expression. In this study, to develop prodrugs of roxadustat with improved permeability through cell membrane, we investigated the effects of 8 types of esterification on the pharmacokinetics and bioactivity of roxadustat using Hep3B hepatoma cells that HIF-dependently produce EPO. Mass spectrometry of cells incubated with the esterified roxadustat derivatives revealed that the designed compounds were deesterified after being taken up by cells and showed low cytotoxicity compared to the original compound. Esterification prolonged the effective duration of roxadustat with respect to EPO gene induction and HIF activation in cells transiently exposed to the compounds. In the kidneys and livers of mice, both of which are unique sites of EPO production, a majority of the methyl-esterified roxadustat was deesterified within 6 h after drug administration. The deesterified roxadustat derivative was continuously detectable in plasma and urine for at least 48 h after administration, while the administered compound became undetectable 24 h after administration. Additionally, we confirmed that methyl-esterified roxadustat activated erythropoiesis in mice by inducing Epo mRNA expression exclusively in renal interstitial cells, which have intrinsic EPO-producing potential. These data suggest that esterification could lead to the development of roxadustat prodrugs with improvements in cell membrane permeability, effective duration and cytotoxicity.

    Skin is constantly exposed to environmental insults, including toxic chemicals and oxidative stress. These insults often provoke perturbation of epidermal homeostasis and lead to characteristic skin diseases. AHR (aryl hydrocarbon receptor) and NRF2 (nuclear factor erythroid 2-related factor 2) are transcription factors that induce a battery of cytoprotective genes encoding detoxication and antioxidant enzymes in response to environmental insults. In addition to their basic functions as key regulators of xenobiotic and oxidant detoxification, recent investigations revealed that AHR and NRF2 also play critical roles in the maintenance of skin homeostasis. In fact, specific disruption of AHR function in the skin has been found to be associated with the pathogenesis of various skin diseases, most prevalently atopic dermatitis (AD). In this review, current knowledge on the roles that AHR and NRF2 play in epidermal homeostasis was summarized. Functional annotations of genetic variants, both regulatory and nonsynonymous SNPs, identified in the AHR and NRF2 loci in the human genome were also summarized. Finally, the possibility that AHR and NRF2 serve as therapeutic targets of AD was assessed.

    Transcription factor Nrf2 and its negative regulator Keap1 orchestrate a cytoprotective response against oxidative, metabolic, and inflammatory stress. Keap1 is a drug target, with several small molecules in drug development. Here, we show that the isoquinoline PRL-295 increased Keap1 thermostability in lysates from cells expressing fluorescently tagged Keap1. The thermostability of endogenous Keap1 also increased in intact cells and murine liver following PRL-295 treatment. Fluorescence Lifetime Imaging-Förster Resonance Energy Transfer (FLIM-FRET) experiments in cells co-expressing sfGFP-Nrf2 and Keap1-mCherry further showed that PRL-295 prolonged the donor fluorescence lifetime, indicating disruption of the Keap1-Nrf2 protein complex. Orally administered PRL-295 to mice activated the Nrf2transcriptional target NAD(P)H:quinone oxidoreductase 1 (NQO1) in liver and decreased the levels of plasma alanine aminotransferase and aspartate aminotransferase upon acetaminophen-induced hepatic injury. Thus, PRL-295 engages the Keap1 protein target in cells and in vivo, disrupting its interaction with Nrf2, leading to activation of Nrf2-dependent transcription and hepatocellular protection.

    BACKGROUND: This study was to systematically test whether previously reported risk factors for chronic kidney disease (CKD) are causally related to CKD in European and East Asian ancestries using Mendelian randomization. METHODS: A total of 45 risk factors with genetic data in European ancestry and 17 risk factors in East Asian participants were identified as exposures from PubMed. We defined the CKD by clinical diagnosis or by estimated glomerular filtration rate of <60 ml/min/1.73 m2. Ultimately, 51 672 CKD cases and 958 102 controls of European ancestry from CKDGen, UK Biobank and HUNT, and 13 093 CKD cases and 238 118 controls of East Asian ancestry from Biobank Japan, China Kadoorie Biobank and Japan-Kidney-Biobank/ToMMo were included. RESULTS: Eight risk factors showed reliable evidence of causal effects on CKD in Europeans, including genetically predicted body mass index (BMI), hypertension, systolic blood pressure, high-density lipoprotein cholesterol, apolipoprotein A-I, lipoprotein(a), type 2 diabetes (T2D) and nephrolithiasis. In East Asians, BMI, T2D and nephrolithiasis showed evidence of causality on CKD. In two independent replication analyses, we observed that increased hypertension risk showed reliable evidence of a causal effect on increasing CKD risk in Europeans but in contrast showed a null effect in East Asians. Although liability to T2D showed consistent effects on CKD, the effects of glycaemic phenotypes on CKD were weak. Non-linear Mendelian randomization indicated a threshold relationship between genetically predicted BMI and CKD, with increased risk at BMI of >25 kg/m2. CONCLUSIONS: Eight cardiometabolic risk factors showed causal effects on CKD in Europeans and three of them showed causality in East Asians, providing insights into the design of future interventions to reduce the burden of CKD.

    Deficiency of the small Maf proteins Mafg and Mafk cause multiple defects, namely, progressive neuronal degeneration, cataract, thrombocytopenia and mid-gestational/perinatal lethality. Previous data shows Mafg -/-:Mafk +/- compound knockout (KO) mice exhibit cataracts age 4-months onward. Strikingly, Mafg -/-:Mafk -/- double KO mice develop lens defects significantly early in life, during embryogenesis, but the pathobiology of these defects is unknown, and is addressed here. At embryonic day (E)16.5, the epithelium of lens in Mafg -/-:Mafk -/- animals appears abnormally multilayered as demonstrated by E-cadherin and nuclear staining. Additionally, Mafg -/-:Mafk -/- lenses exhibit abnormal distribution of F-actin near the "fulcrum" region where epithelial cells undergo apical constriction prior to elongation and reorientation as early differentiating fiber cells. To identify the underlying molecular changes, we performed high-throughput RNA-sequencing of E16.5 Mafg -/-:Mafk -/- lenses and identified a cohort of differentially expressed genes that were further prioritized using stringent filtering criteria and validated by RT-qPCR. Several key factors associated with the cytoskeleton, cell cycle or extracellular matrix (e.g., Cdk1, Cdkn1c, Camsap1, Col3a1, Map3k12, Sipa1l1) were mis-expressed in Mafg -/-:Mafk -/- lenses. Further, the congenital cataract-linked extracellular matrix peroxidase Pxdn was significantly overexpressed in Mafg -/-:Mafk -/- lenses, which may cause abnormal cell morphology. These data also identified the ephrin signaling receptor Epha5 to be reduced in Mafg -/-:Mafk -/- lenses. This likely contributes to the Mafg -/-:Mafk -/- multilayered lens epithelium pathology, as loss of an ephrin ligand, Efna5 (ephrin-A5), causes similar lens defects. Together, these findings uncover a novel early function of Mafg and Mafk in lens development and identify their new downstream regulatory relationships with key cellular factors.

    Space travel burdens health by imposing considerable environmental stress associated with radioactivity and microgravity. In particular, gravity change predominantly impacts blood pressure and bone homeostasis, both of which are controlled mainly by the kidneys. Nuclear factor erythroid-2-related transcription factor 2 (Nrf2) plays essential roles in protecting the kidneys from various environmental stresses and injuries. To elucidate the effects of space travel on mammals in preparation for the upcoming space era, our study investigated the contribution of Nrf2 to kidney function in mice two days after their return from a 31-day stay in the International Space Station using Nrf2 knockout mice. Meaningfully, expression levels of genes regulating bone mineralization, blood pressure and lipid metabolism were found to be significantly altered in the kidneys after space travel in an Nrf2-independent manner. In particular, uridine diphosphate-glucuronosyltransferase 1A (Ugt1a) isoform genes were found to be expressed in an Nrf2-dependent manner and induced exclusively in the kidneys after return to Earth. Since spaceflight elevated the concentrations of fatty acids in the mouse plasma, we suggest that Ugt1a isoform expression in the kidneys was induced to promote glucuronidation of excessively accumulated lipids and excrete them into urine after the return from space. Thus, the kidneys were proven to play central roles in adaptation to gravity changes caused by going to and returning from space by controlling blood pressure and bone mineralization. Additionally, kidney Ugt1a isoform induction after space travel implies a significant role of the kidneys for space travelers in the excretion of excessive lipids.

    To reveal gene-environment interactions underlying common diseases and estimate the risk for common diseases, the Tohoku Medical Megabank (TMM) project has conducted prospective cohort studies and genomic and multiomics analyses. To establish an integrated biobank, we developed an integrated database called "dbTMM" that incorporates both the individual cohort/clinical data and the genome/multiomics data of 157,191 participants in the Tohoku Medical Megabank project. To our knowledge, dbTMM is the first database to store individual whole-genome data on a variant-by-variant basis as well as cohort/clinical data for over one hundred thousand participants in a prospective cohort study. dbTMM enables us to stratify our cohort by both genome-wide genetic factors and environmental factors, and it provides a research and development platform that enables prospective analysis of large-scale data from genome cohorts.

    Space travel induces stresses that contribute to health problems, as well as inducing the expression of Nrf2 (NF-E2-related factor-2) target genes that mediate adaptive responses to oxidative and other stress responses. The volume of epididymal white adipose tissue (eWAT) in mice increases during spaceflight, a change that is attenuated by Nrf2 knockout. We conducted metabolome analyses of plasma from wild-type and Nrf2 knockout mice collected at pre-flight, in-flight and post-flight time points, as well as tissues collected post-flight to clarify the metabolic responses during and after spaceflight and the contribution of Nrf2 to these responses. Plasma glycerophospholipid and sphingolipid levels were elevated during spaceflight, whereas triacylglycerol levels were lower after spaceflight. In wild-type mouse eWAT, triacylglycerol levels were increased, but phosphatidylcholine levels were decreased, and these changes were attenuated in Nrf2 knockout mice. Transcriptome analyses revealed marked changes in the expression of lipid-related genes in the liver and eWAT after spaceflight and the effects of Nrf2 knockout on these changes. Based on these results, we concluded that space stress provokes significant responses in lipid metabolism during and after spaceflight; Nrf2 plays critical roles in these responses.

    Oxygen plays an important role in diverse biological processes. However, since quantitation of the partial pressure of cellular oxygen in vivo is challenging, the extent of oxygen perturbation in situ and its cellular response remains underexplored. Using two-photon phosphorescence lifetime imaging microscopy, we determine the physiological range of oxygen tension in osteoclasts of live mice. We find that oxygen tension ranges from 17.4 to 36.4 mmHg, under hypoxic and normoxic conditions, respectively. Physiological normoxia thus corresponds to 5% and hypoxia to 2% oxygen in osteoclasts. Hypoxia in this range severely limits osteoclastogenesis, independent of energy metabolism and hypoxia-inducible factor activity. We observe that hypoxia decreases ten-eleven translocation (TET) activity. Tet2/3 cooperatively induces Prdm1 expression via oxygen-dependent DNA demethylation, which in turn activates NFATc1 required for osteoclastogenesis. Taken together, our results reveal that TET enzymes, acting as functional oxygen sensors, regulate osteoclastogenesis within the physiological range of oxygen tension, thus opening new avenues for research on in vivo response to oxygen perturbation.

    Increased blood lipid levels are heritable risk factors of cardiovascular disease with varied prevalence worldwide owing to different dietary patterns and medication use1. Despite advances in prevention and treatment, in particular through reducing low-density lipoprotein cholesterol levels2, heart disease remains the leading cause of death worldwide3. Genome-wideassociation studies (GWAS) of blood lipid levels have led to important biological and clinical insights, as well as new drug targets, for cardiovascular disease. However, most previous GWAS4-23 have been conducted in European ancestry populations and may have missed genetic variants that contribute to lipid-level variation in other ancestry groups. These include differences in allele frequencies, effect sizes and linkage-disequilibrium patterns24. Here we conduct a multi-ancestry, genome-wide genetic discovery meta-analysis of lipid levels in approximately 1.65 million individuals, including 350,000 of non-European ancestries. We quantify the gain in studying non-European ancestries and provide evidence to support the expansion of recruitment of additional ancestries, even with relatively small sample sizes. We find that increasing diversity rather than studying additional individuals of European ancestry results in substantial improvements in fine-mapping functional variants and portability of polygenic prediction (evaluated in approximately 295,000 individuals from 7 ancestry groupings). Modest gains in the number of discovered loci and ancestry-specific variants were also achieved. As GWAS expand emphasis beyond the identification of genes and fundamental biology towards the use of genetic variants for preventive and precision medicine25, we anticipate that increased diversity of participants will lead to more accurate and equitable26 application of polygenic scores in clinical practice.

    BACKGROUND: Trajectories of postpartum depressive symptoms up to 1 year after childbirth and the related risk factors remain unclear. Accordingly, this study aimed to examine the 1-year trajectories of postpartum depressive symptoms and their associated risk factors. METHODS: A total of 22,493 pregnant women were recruited between July 2013 and September 2016 in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study in Japan. Among them, 11,668 women with no missing data were included in the analyses. Depressive symptoms were assessed at 1 month and 1 year postpartum using the Edinburgh Postnatal Depression Scale. Multinominal logistic regression analysis was conducted after adjusting for covariates. RESULTS: The prevalence of depression was 13.9% at 1 month and 12.9% at 1 year postpartum. We identified four depression trajectories, i.e., "persistent (depressed throughout the 1 year postpartum)" (6.0%), "recovered (depressed at 1 month postpartum and recovered within a year)" (7.9%), "late-onset (became depressed after 1 month postpartum)" (6.8%), and "resilient (not depressed throughout 1 year postpartum)" (79.2%). Psychological distress during pregnancy was significantly associated with all trajectories (persistent: odds ratio [OR]=10.24, 95% confidence interval (CI)=8.40-12.48; recovered: OR=3.78, 95%CI=3.28-4.36; and late-onset: OR=3.96, 95%CI=3.40-4.62). LIMITATIONS: Postpartum depression was evaluated only by a self-administered questionnaire and the dropout rate was not neglectable. CONCLUSIONS: This study highlighted the high prevalence of depressive symptoms at 1 year postpartum and found that half of the depressive symptoms at 1 year were late-onset. The findings suggest the necessity of long-term follow-up (up to 1 year) for perinatal mental health.

Because type 2 airway inflammation influences lung function, genome wide association studies (GWAS) for lung function would be improved by adjustment with an indicator of the inflammation. Here, we performed a GWAS for lung function with adjustment for exhaled nitric oxide (FeNO) levels in two independent Japanese populations. Our GWAS with genotype imputations revealed that the RNF5/AGER locus including AGER rs2070600 SNP, which introduces a G82S substitution of AGER, was the most significantly associated with FEV1/FVC. Three other rare missense variants of AGER were further identified. We also found genetic loci with three candidate genes (NOS2, SPSB2 and RIPOR2) associated with FeNO levels. Analyses with the BioBank-Japan GWAS resource revealed genetic links of FeNO and asthma-related traits, and existence of common genetic background for allergic diseases and their biomarkers. Our study identified the genetic locus most strongly associated with airway obstruction in the Japanese population and three genetic loci associated with FeNO, an indicator of type 2 airway inflammation in adults.

    Parkinson's disease (PD) is a progressive neurodegenerative movement disorder characterized by the loss of nigrostriatal dopaminergic neurons. Mounting evidence suggests that Nrf2 is a promising target for neuroprotective interventions in PD. However, electrophilic chemical properties of the canonical Nrf2-based drugs cause irreversible alkylation of cysteine residues on cellular proteins resulting in side effects. Bach1 is a known transcriptional repressor of the Nrf2 pathway. We report that Bach1 levels are up-regulated in PD postmortem brains and preclinical models. Bach1 knockout (KO) mice were protected against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic neurotoxicity and associated oxidative damage and neuroinflammation. Functional genomic analysis demonstrated that the neuroprotective effects in Bach1 KO mice was due to up-regulation of Bach1-targeted pathways that are associated with both Nrf2-dependent antioxidant response element (ARE) and Nrf2-independent non-ARE genes. Using a proprietary translational technology platform, a drug library screen identified a substituted benzimidazole as a Bach1 inhibitor that was validated as a nonelectrophile. Oral administration of the Bach1 inhibitor attenuated MPTP neurotoxicity in pre- and posttreatment paradigms. Bach1 inhibitor-induced neuroprotection was associated with the up-regulation of Bach1-targeted pathways in concurrence with the results from Bach1 KO mice. Our results suggest that genetic deletion as well as pharmacologic inhibition of Bach1 by a nonelectrophilic inhibitor is a promising therapeutic approach for PD.

    Fine-tuning of osteoclast differentiation (OD) and bone remodeling is crucial for bone homeostasis. Dissecting the mechanisms regulating osteoclastogenesis is fundamental to understanding the pathogenesis of various bone disorders including osteoporosis and arthritis. Nuclear factor erythroid 2-related factor 1 (NFE2L1, also known as NRF1), which belongs to the CNC-bZIP family of transcription factors, orchestrates a variety of physiological processes and stress responses. While Nfe2l1 gene may be transcribed into multiple alternatively spliced isoforms, the biological function of the different isoforms of NFE2L1 in bone metabolism, osteoclastogenesis in particular, has not been reported. Here we demonstrate that knockout of all isoforms of Nfe2l1 transcripts specifically in the myeloid lineage in mice [Nfe2l1(M)-KO] results in increased activity of osteoclasts, decreased bone mass and worsening of osteoporosis induced by ovariectomy and aging. In comparison, LysM-Cre-mediated Nfe2l1 deletion has no significant effect on the osteoblast and osteocytes. Mechanistic investigations using bone marrow cells and RAW 264.7 cells revealed that deficiency of Nfe2l1 leads to accelerated and elevated OD, which is attributed, at least in part, to enhanced accumulation of ROS in the early stage of OD and expression of nuclear factor of activated T cells, cytoplasmic, calcineurin dependent 1α (Nfatc1/α). In addition, NFE2L1 regulates the transcription of multiple antioxidant genes and Nfatc1/α and OD in an isoform-specific manner. While long isoforms of NFE2L1 function as accelerators of induction of Nfatc1/α and antioxidant genes and OD, the short isoform NFE2L1-453 serves as a brake that keeps the long isoforms' accelerator effects in check. These findings provide a novel insight into the regulatory roles of NFE2L1 in osteoclastogenesis and highlight that NFE2L1 is essential in regulating bone remodeling and thus may be a valuable therapeutic target for bone disorders.

    Histone H3 lysine 4 methylation (H3K4Me) is most often associated with chromatin activation, and removing H3K4 methyl groups has been shown to be coincident with gene repression. H3K4Me demethylase KDM1a/LSD1 is a therapeutic target for multiple diseases, including for the potential treatment of β-globinopathies (sickle cell disease and β-thalassemia), because it is a component of γ-globin repressor complexes, and LSD1 inactivation leads to robust induction of the fetal globin genes. The effects of LSD1 inhibition in definitive erythropoiesis are not well characterized, so we examined the consequences of conditional inactivation of Lsd1 in adult red blood cells using a new Gata1creERT2 bacterial artificial chromosome transgene. Erythroid-specific loss of Lsd1 activity in mice led to a block in erythroid progenitor differentiation and to the expansion of granulocyte-monocyte progenitor-like cells, converting hematopoietic differentiation potential from an erythroid fate to a myeloid fate. The analogous phenotype was also observed in human hematopoietic stem and progenitor cells, coincident with the induction of myeloid transcription factors (eg, PU.1 and CEBPα). Finally, blocking the activity of the transcription factor PU.1 or RUNX1 at the same time as LSD1 inhibition rescued myeloid lineage conversion to an erythroid phenotype. These data show that LSD1 promotes erythropoiesis by repressing myeloid cell fate in adult erythroid progenitors and that inhibition of the myeloid-differentiation pathway reverses the lineage switch induced by LSD1 inactivation.

    Heme oxygenase 1 (HO-1) is the key enzyme for heme catabolism and cytoprotection. Whereas HO-1 gene expression in response to various stresses has been investigated extensively, the precise mechanisms by which HO-1 gene expression is regulated by the HO-1 substrate heme remain elusive. To systematically examine whether stress-mediated induction and substrate-mediated induction of HO-1 utilize similar or distinct regulatory pathways, we developed an HO-1-DsRed-knock-in reporter mouse in which the HO-1 gene is floxed by loxP sites and the DsRed gene has been inserted. Myeloid lineage-specific recombination of the floxed locus led to fluorescence derived from expression of the HO-1-DsRed fusion protein in peritoneal macrophages. We also challenged general recombination of the locus and generated mice harboring heterozygous recombinant alleles, which enabled us to monitor HO-1-DsRed expression in the whole body in vivo and ex vivo. HO-1 inducers upregulated HO-1-DsRed expression in myeloid lineage cells isolated from the mice. Notably, analyses of peritoneal macrophages from HO-1-DsRed mice lacking NRF2, a major regulator of the oxidative/electrophilic stress response, led us to identify NRF2-dependent stress response-mediated HO-1 induction and NRF2-independent substrate-mediated HO-1 induction. Thus, the HO-1 gene is subjected to at least two distinct levels of regulation, and the available lines of evidence suggest that substrate induction in peritoneal macrophages is independent of CNC family-based regulation.

    Lipids, such as cholesterol and fatty acids, influence cell signaling, energy storage, and membrane formation. Cholesterol is biosynthesized through the mevalonate pathway, and aberrant metabolism causes metabolic diseases. The genetic association of a transcription factor NRF3 with obesity has been suggested, although the molecular mechanisms remain unknown. Here, we show that NRF3 upregulates gene expression in SREBP2-dependent mevalonate pathway. We further reveal that NRF3 overexpression not only reduces lanosterol, a cholesterol precursor, but also induces the expression of the GGPS1 gene encoding an enzyme in the production of GGPP from farnesyl pyrophosphate (FPP), a lanosterol precursor. NRF3 overexpression also enhances cholesterol uptake through RAB5-mediated macropinocytosis process, a bulk and fluid-phase endocytosis pathway. Moreover, we find that GGPP treatment abolishes NRF3 knockdown-mediated increase of neutral lipids. These results reveal the potential roles of NRF3 in the SREBP2-dependent mevalonate pathway for cholesterol uptake through macropinocytosis induction and for lipogenesis inhibition through GGPP production.

    BACKGROUND: This study was to systematically test whether previously reported risk factors for chronic kidney disease (CKD) are causally related to CKD in European and East Asian ancestries using Mendelian randomization. METHODS: A total of 45 risk factors with genetic data in European ancestry and 17 risk factors in East Asian participants were identified as exposures from PubMed. We defined the CKD by clinical diagnosis or by estimated glomerular filtration rate of <60 ml/min/1.73 m2. Ultimately, 51 672 CKD cases and 958 102 controls of European ancestry from CKDGen, UK Biobank and HUNT, and 13 093 CKD cases and 238 118 controls of East Asian ancestry from Biobank Japan, China Kadoorie Biobank and Japan-Kidney-Biobank/ToMMo were included. RESULTS: Eight risk factors showed reliable evidence of causal effects on CKD in Europeans, including genetically predicted body mass index (BMI), hypertension, systolic blood pressure, high-density lipoprotein cholesterol, apolipoprotein A-I, lipoprotein(a), type 2 diabetes (T2D) and nephrolithiasis. In East Asians, BMI, T2D and nephrolithiasis showed evidence of causality on CKD. In two independent replication analyses, we observed that increased hypertension risk showed reliable evidence of a causal effect on increasing CKD risk in Europeans but in contrast showed a null effect in East Asians. Although liability to T2D showed consistent effects on CKD, the effects of glycaemic phenotypes on CKD were weak. Non-linear Mendelian randomization indicated a threshold relationship between genetically predicted BMI and CKD, with increased risk at BMI of >25 kg/m2. CONCLUSIONS: Eight cardiometabolic risk factors showed causal effects on CKD in Europeans and three of them showed causality in East Asians, providing insights into the design of future interventions to reduce the burden of CKD.

    As the central regulator of the oxidative stress response, nuclear factor erythroid 2-related factor 2 (Nrf2) is attracting great interest as a therapeutic target for various cancers, and the possible clinical applications of novel Nrf2 inhibitors have been explored in Nrf2-activated cancers. In the present study, we specifically investigated halofuginone, which is derived from a natural plant alkaloid. We found that halofuginone administration decreased the number of pancreatic intraepithelial neoplasias in pancreas-specific Kras and p53 mutant (KPC) mice. In Nrf2-activated pancreatic cancer cell lines established from KPC mice, halofuginone rapidly depleted Nrf2 in Nrf2-activated cancer cells. Both in vitro and in vivo, it sensitized Nrf2-activated pancreatic cancer cells to gemcitabine, which is the first-line chemotherapy in clinical practice. In our mechanistic study, we found that halofuginone downregulated aldehyde dehydrogenase 3a1 (ALDH3A1) in mouse pancreatic cancer cells. The Nrf2 inducer diethyl maleate upregulated ALDH3A1, and knockdown of Aldh3a1 sensitized Nrf2-activated cancer cells to gemcitabine, strongly suggesting that ALDH3A1 is regulated by Nrf2 and that it contributes to gemcitabine resistance. The current study demonstrated the therapeutic benefits of halofuginone in Nrf2-activated pancreatic cancers. SIGNIFICANCE STATEMENT: We identified nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream target aldehyde dehydrogenase 3a1 (ALDH3A1) as novel therapeutic targets in pancreatic cancer. They negatively affect the efficacy of a conventional chemotherapeutic agent, gemcitabine. We confirmed that Nrf2 plays a pivotal role in the induction of ALDH3A1.

    It was previously identified that systemic Nrf2 deletion attenuates pancreatic cancer progression in a mutant K-ras/p53-expressing mouse model (KPC mouse). In this study, the type of cell that is responsible for the retarded cancer progression was elucidated. Human pancreatic cancers were first examined, and elevated expression of NRF2-target gene products in α-smooth muscle actin-positive cells was found, suggesting that pancreatic stellate cells (PSCs) are involved in this process. Closer examination of primary cultured PSCs from Nrf2-deleted mice revealed that the cells were less proliferative and retained a lower migration capacity. The conditioned medium of Nrf2-deleted PSCs exhibited reduced growth-stimulating effects in pancreatic cancer cells. KPC mouse-derived pancreatic cancer cells coinjected with wild-type PSCs developed significantly larger subcutaneous tumors in immunodeficient mice than those coinjected with Nrf2-deleted PSCs. These results demonstrate that Nrf2 actively contributes to the function of PSCs to sustain KPC cancer progression, thus, suggesting that Nrf2 inhibition in PSCs may be therapeutically important in pancreatic cancer.NEW & NOTEWORTHY This study identified that Nrf2 contributes to PSC activation. Nrf2 deletion in PSCs resulted in attenuation of cancer-promoting role. Nrf2 in PSCs could be an attractive therapeutic target in pancreatic cancer.

    Current genome-wide association studies do not yet capture sufficient diversity in populations and scope of phenotypes. To expand an atlas of genetic associations in non-European populations, we conducted 220 deep-phenotype genome-wide association studies (diseases, biomarkers and medication usage) in BioBank Japan (n = 179,000), by incorporating past medical history and text-mining of electronic medical records. Meta-analyses with the UK Biobank and FinnGen (ntotal = 628,000) identified ~5,000 new loci, which improved the resolution of the genomic map of human traits. This atlas elucidated the landscape of pleiotropy as represented by the major histocompatibility complex locus, where we conducted HLA fine-mapping. Finally, we performed statistical decomposition of matrices of phenome-wide summary statistics, and identified latent genetic components, which pinpointed responsible variants and biological mechanisms underlying current disease classifications across populations. The decomposed components enabled genetically informed subtyping of similar diseases (for example, allergic diseases). Our study suggests a potential avenue for hypothesis-free re-investigation of human diseases through genetics.

    Metabolic profiling is an omics approach that can be used to observe phenotypic changes, making it particularly attractive for biomarker discovery. Although several candidate metabolites biomarkers for disease expression have been identified in recent clinical studies, the reference values of healthy subjects have not been established. In particular, the accuracy of concentrations measured by mass spectrometry (MS) is unclear. Therefore, comprehensive metabolic profiling in large-scale cohorts by MS to create a database with reference ranges is essential for evaluating the quality of the discovered biomarkers. In this study, we tested 8700 plasma samples by commercial kit-based metabolomics and separated them into two groups of 6159 and 2541 analyses based on the different ultra-high-performance tandem mass spectrometry (UHPLC-MS/MS) systems. We evaluated the quality of the quantified values of the detected metabolites from the reference materials in the group of 2541 compared with the quantified values from other platforms, such as nuclear magnetic resonance (NMR), supercritical fluid chromatography tandem mass spectrometry (SFC-MS/MS) and UHPLC-Fourier transform mass spectrometry (FTMS). The values of the amino acids were highly correlated with the NMR results, and lipid species such as phosphatidylcholines and ceramides showed good correlation, while the values of triglycerides and cholesterol esters correlated less to the lipidomics analyses performed using SFC-MS/MS and UHPLC-FTMS. The evaluation of the quantified values by MS-based techniques is essential for metabolic profiling in a large-scale cohort.

    Air pollution is associated with significant adverse health effects. Recent studies support the idea that inhalation of fine particles can instigate extrapulmonary effects on the cardiovascular system through several pathways. The systemic transfer of ultrafine particles (UFPs) or soluble particle components (organic compounds and metals) is of particular concern. An integral role of reactive oxygen species (ROS)-dependent pathways has been suggested in systemic inflammatory responses and vascular dysfunction at the molecular level. Accumulating lines of evidence suggest that fine particles affect fetal development, giving rise to low birth weight and a reduction in fetal growth, and also affect the immune, cardiovascular, and central nervous systems. Oxidative stress plays an important role in fine particles toxicity; pre-treatment with antioxidants partially suppresses the developmental toxicity of fine particles. On the other hand, Nuclear factor erythroid-derived 2-like 2 (Nfe2l2), also known as NRF2, is a transcription factor essential for inducible and/or constitutive expression of phase II and antioxidant enzymes. Studies using <italic>Nrf2</italic>-knockout mice revealed that NRF2 dysfunction is intimately involved in the pathogenesis of various human diseases. Multiple single nucleotide polymorphisms (SNPs) have been detected in human <italic>NRF2</italic> locus. An <italic>NRF2</italic> gene SNP (−617C &amp;gt; A; rs6721961), located in the upstream promoter region, affects the transcriptional level of NRF2 and thereby the protein level and downstream gene expression. It has been reported that the SNP-617 is associated with various diseases. The onset and exacerbation of the diseases are regulated by genetic predisposition and environmental factors; some people live in the air-polluted environment but are not affected and remain healthy, suggesting the presence of individual differences in the susceptibility to air pollutants. NRF2 polymorphisms may also be associated with the fetal effects of fine particles exposure. Screening high-risk pregnant women genetically susceptible to oxidative stress and prevention by antioxidant interventions to protect fetal development in air-polluted areas should be considered. This article reviews the recent advances in our understanding of the fetal health effects of fine particles and describes potential chemoprevention <italic>via</italic> the NRF2 pathway to prevent the developmental and reproductive toxicity of fine particles.

    The elucidation of dynamic metabolomic changes during gestation is particularly important for the development of methods to evaluate pregnancy status or achieve earlier detection of pregnancy-related complications. Some studies have constructed models to evaluate pregnancy status and predict gestational age using omics data from blood biospecimens; however, less invasive methods are desired. Here we propose a model to predict gestational age, using urinary metabolite information. In our prospective cohort study, we collected 2741 urine samples from 187 healthy pregnant women, 23 patients with hypertensive disorders of pregnancy, and 14 patients with spontaneous preterm birth. Using gas chromatography-tandem mass spectrometry, we identified 184 urinary metabolites that showed dynamic systematic changes in healthy pregnant women according to gestational age. A model to predict gestational age during normal pregnancy progression was constructed; the correlation coefficient between actual and predicted weeks of gestation was 0.86. The predicted gestational ages of cases with hypertensive disorders of pregnancy exhibited significant progression, compared with actual gestational ages. This is the first study to predict gestational age in normal and complicated pregnancies by using urinary metabolite information. Minimally invasive urinary metabolomics might facilitate changes in the prediction of gestational age in various clinical settings.

    Glycyrrhizic acid (GA), a major constituent of the root of licorice (Glycyrrhiza glabra), and has various biological activities, including anti-obesity property. However, the molecular mechanism of anti-adipogenic effect of GA is still unclear. In this study, we investigated the anti-adipogenic effects of GA in mouse adipocytic 3T3-L1 cells and elucidated its underlying molecular mechanism. GA decreased the intracellular triglyceride level. The expression levels of the adipogenic and lipogenic genes were lowered by treatment with GA in a concertation-dependent manner. In contrast, GA did not affect the lipolytic gene expression and the released glycerol level. GA suppressed the early stage of adipogenesis when it was added for 0-3 h after initiation of adipogenesis. Moreover, GA reduced the mRNA levels of CCAAT/enhancer binding protein (C/EBP) β and C/EBPδ, both of which activate the early stage of adipogenesis. Furthermore, GA decreased phosphorylation of extracellular signal-regulated kinase [ERK: p44/42 mitogen-activated protein kinase (MAPK)] in the early stage of adipogenesis. In addition, a MAPK kinase (MEK) inhibitor, PD98059 reduced the C/EBPβ and C/EBPδ gene expression. These results indicate that GA suppressed the early stage of adipogenesis through repressing the MEK/ERK-mediated C/EBPβ and C/EBPδ expression in 3T3-L1 cells. Thus, GA has an anti-adipogenic ability and a possible agent for treatment of obesity.

    Bone morphogenetic protein-9 (BMP9), a member of the transforming growth factor β (TGFβ) superfamily, plays important roles in the development and maintenance of various cell lineages via complexes of type I and type II TGFβ receptors. Endoglin is a coreceptor for several TGFβ family members, including BMP9, which is highly expressed in a particular stage of differentiation in erythroid cells as well as in endothelial cells. Although the importance of the interaction between BMP9 and endoglin for endothelial development has been reported, the contribution of BMP9 to endoglin-expressing erythroid cells remains to be clarified. To address this point, we prepared an anti-BMP9 antibody that blocks the BMP9-endoglin interaction. Of note, challenge with the antibody promotes erythropoiesis in wild-type mice but not in a mouse model of renal anemia in which erythropoietin (EPO) production in the kidneys is genetically ablated. While endoglin-positive erythroid progenitors are mainly maintained as progenitors when bone marrow-derived lineage-negative and cKit-positive cells are cultured in the presence of EPO and stem cell factor, the erythroid-biased accumulation of progenitors is impeded by the presence of BMP9. Our findings uncover an unrecognized role for BMP9 in attenuating erythroid differentiation via its interaction with endoglin on erythroid progenitors.

    Pericytes play an important role in the recovery process after ischemic injury of many tissues. Brain pericytes in the peri-infarct area express macrophage markers in response to injury stimuli and are involved in neovascularization. In the kidney, nerve/glial antigen 2 (NG2)+ pericytes have been found to accumulate after renal injury. These accumulated NG2+ cells are not involved in scar formation. However, the role of accumulated NG2+ cells in injured kidneys remains unknown. Here, using a reversible ischemia-reperfusion (I/R) model, we found that renal NG2+ cells were increased in injured kidneys and expressed macrophage markers (CD11b or F4/80) on day 3 after reperfusion. Isolated NG2+ cells from I/R kidneys also had phagocytic activity and expressed anti-inflammatory cytokine genes, including mannose receptor and IL-10. These macrophage-like NG2+ cells did not likely differentiate into myofibroblasts because they did not increase α-smooth muscle actin expression. Intravenous transfusion of renal NG2+ cells isolated from donor mice on day 3 after reperfusion into recipient mice on day 1 after I/R surgery revealed that NG2+ cell-injected mice had lower plasma blood urea nitrogen, reduced kidney injury molecule-1 mRNA expression, ameliorated renal damage, and reduced cellular debris accumulation compared with PBS-injected mice on day 5 after reperfusion. In conclusion, these data suggest that renal NG2+ cells have an M2 macrophage-like ability and play a novel role in facilitating the recovery process after renal I/R injury.NEW & NOTEWORTHY Brain pericytes have macrophage-like activities after injury. However, such properties of pericytes in peripheral tissues have not been investigated. Here, we provide evidence that nerve/glial antigen 2-positive cells increase after renal injury. The population of nerve/glial antigen 2-positive cells, which does not increase expression of myofibroblast-associated gene, express macrophage markers and anti-inflammatory cytokine genes, have phagocytic activity, and play a role in renal recovery after kidney injury.

    Certain large genome cohort studies attempt to return the individual genomic results to the participants; however, the implementation process and psychosocial impacts remain largely unknown. The Tohoku Medical Megabank Project has conducted large genome cohort studies of general residents. To implement the disclosure of individual genomic results, we extracted the potential challenges and obstacles. Major challenges include the determination of genes/disorders based on the current medical system in Japan, the storage of results, prevention of misunderstanding, and collaboration of medical professionals. To overcome these challenges, we plan to conduct multilayer pilot studies, which deal with different disorders/genes. We finally chose familial hypercholesterolemia (FH) as a target disease for the first pilot study. Of the 665 eligible candidates, 33.5% were interested in the pilot study and provided consent after an educational "genetics workshop" on the basic genetics and medical facts of FH. The genetics professionals disclosed the results to the participants. All positive participants were referred to medical care, and a serial questionnaire revealed no significant psychosocial distress after the disclosure. Return of genomic results to research participants was implemented using a well-prepared protocol. To further elucidate the impact of different disorders, we will perform multilayer pilot studies with different disorders, including actionable pharmacogenomics and hereditary tumor syndromes.

    Epithelial ovarian cancer (EOC) is a fatal gynecologic cancer, and its poor prognosis is mainly due to delayed diagnosis. Therefore, biomarker identification and prognosis prediction are crucial in EOC. Altered cell metabolism is a characteristic feature of cancers, and metabolomics reflects an individual's current phenotype. In particular, plasma metabolome analyses can be useful for biomarker identification. In this study, we analyzed 624 metabolites, including uremic toxins (UTx) in plasma derived from 80 patients with EOC using ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Compared with the healthy control, we detected 77 significantly increased metabolites and 114 significantly decreased metabolites in EOC patients. Especially, decreased concentrations of lysophosphatidylcholines and phosphatidylcholines and increased concentrations of triglycerides were observed, indicating a metabolic profile characteristic of EOC patients. After calculating the parameters of each metabolic index, we found that higher ratios of kynurenine to tryptophan correlates with worse prognosis in EOC patients. Kynurenine, one of the UTx, can affect the prognosis of EOC. Our results demonstrated that plasma metabolome analysis is useful not only for the diagnosis of EOC, but also for predicting prognosis with the variation of UTx and evaluating response to chemotherapy.

    <title>Abstract</title>Microgravity induces skeletal muscle atrophy, particularly in the soleus muscle, which is predominantly composed of slow-twitch myofibre (type I) and is sensitive to disuse. Muscle atrophy is commonly known to be associated with increased production of reactive oxygen species. However, the role of NRF2, a master regulator of antioxidative response, in skeletal muscle plasticity during microgravity-induced atrophy, is not known. To investigate the role of NRF2 in skeletal muscle within a microgravity environment, wild-type and <italic>Nrf2-</italic>knockout (KO) mice were housed in the International Space Station for 31 days. Gene expression and histological analyses demonstrated that, under microgravity conditions, the transition of type I (oxidative) muscle fibres to type IIa (glycolytic) was accelerated in <italic>Nrf2</italic>-KO mice without affecting skeletal muscle mass. Therefore, our results suggest that NRF2 affects myofibre type transition during space flight.

    The Keap1-Nrf2 system is central for mammalian cytoprotection against various stresses and a drug target for disease prevention and treatment. One model for the molecular mechanisms leading to Nrf2 activation is the Hinge-Latch model, where the DLGex-binding motif of Nrf2 dissociates from Keap1 as a latch, while the ETGE motif remains attached to Keap1 as a hinge. To overcome the technical difficulties in examining the binding status of the two motifs during protein-protein interaction (PPI) simultaneously, we utilized NMR spectroscopy titration experiments. Our results revealed that latch dissociation is triggered by low-molecular-weight Keap1-Nrf2 PPI inhibitors and occurs during p62-mediated Nrf2 activation, but not by electrophilic Nrf2 inducers. This study demonstrates that Keap1 utilizes a unique Hinge-Latch mechanism for Nrf2 activation upon challenge by non-electrophilic PPI-inhibiting stimuli, and provides critical insight for the pharmacological development of next-generation Nrf2 activators targeting the Keap1-Nrf2 PPI.

    <title>Abstract</title> Ethnic-specific SNP arrays are becoming more important to increase the power of genome-wide association studies in diverse population. In the Tohoku Medical Megabank Project, we have been developing a series of Japonica Arrays (JPA) for genotyping participants based on reference panels constructed from whole-genome sequence data of the Japanese population. Here, we designed a novel version of the SNP array for the Japanese population, called Japonica Array NEO (JPA NEO), comprising a total of 666,883 markers. Among them, 654,246 tag SNPs of autosomes and X chromosome were selected from an expanded reference panel of 3,552 Japanese, 3.5KJPNv2, using pairwise r2 of linkage disequilibrium measures. Additionally, 28,298 markers were included for the evaluation of previously identified disease risk markers from the literature and databases, and those present in the Japanese population were extracted using the reference panel. Through genotyping 286 Japanese samples, we found that the imputation quality r2 and INFO score in the minor allele frequency bin &amp;gt;2.5–5% were &amp;gt;0.9 and &amp;gt;0.8, respectively, and &amp;gt;12 million markers were imputed with an INFO score &amp;gt;0.8. From these results, JPA NEO is a promising tool for genotyping the Japanese population with genome-wide coverage, contributing to the development of genetic risk scores.

    Clarification of the criteria for managing animal health is essential to increase the reliability of experiments and ensure transparency in animal welfare. For experiments performed in space, there is no consensus on how to care for animals owing to technical issues, launch mass limitation, and human resources. Some biological processes in mammals, such as musculoskeletal or immune processes, are altered in the space environment, and mice in space can be used to simulate morbid states, such as senescence acceleration. Thus, there is a need to establish a novel evaluation method and evaluation criteria to monitor animal health. Here, we report a novel method to evaluate the health of mice in space through a video downlink in a series of space experiments using the Multiple Artificial-gravity Research System (MARS). This method was found to be more useful in evaluating animal health in space than observations and body weight changes of the same live mice following their return to Earth. We also developed criteria to evaluate health status via a video downlink. These criteria, with "Fur condition" and "Respiratory" as key items, provided information on the daily changes in the health status of mice and helped to identify malfunctions at an early stage. Our method and criteria led to the success of our missions, and they will help establish appropriate rules for space experiments in the future.

    BACKGROUND: Coronary artery disease (CAD) is a multifactorial condition with both genetic and exogenous causes. The contribution of tissue-specific functional networks to the development of atherosclerosis remains largely unclear. The aim of this study was to identify and characterize central regulators and networks leading to atherosclerosis. METHODS: Based on several hundred genes known to affect atherosclerosis risk in mouse (as demonstrated in knockout models) and human (as shown by genome-wide association studies), liver gene regulatory networks were modeled. The hierarchical order and regulatory directions of genes within the network were based on Bayesian prediction models, as well as experimental studies including chromatin immunoprecipitation DNA-sequencing, chromatin immunoprecipitation mass spectrometry, overexpression, small interfering RNA knockdown in mouse and human liver cells, and knockout mouse experiments. Bioinformatics and correlation analyses were used to clarify associations between central genes and CAD phenotypes in both human and mouse. RESULTS: The transcription factor MAFF (MAF basic leucine zipper transcription factor F) interacted as a key driver of a liver network with 3 human genes at CAD genome-wide association studies loci and 11 atherosclerotic murine genes. Most importantly, expression levels of the low-density lipoprotein receptor (LDLR) gene correlated with MAFF in 600 CAD patients undergoing bypass surgery (STARNET [Stockholm-Tartu Atherosclerosis Reverse Network Engineering Task]) and a hybrid mouse diversity panel involving 105 different inbred mouse strains. Molecular mechanisms of MAFF were tested in noninflammatory conditions and showed positive correlation between MAFF and LDLR in vitro and in vivo. Interestingly, after lipopolysaccharide stimulation (inflammatory conditions), an inverse correlation between MAFF and LDLR in vitro and in vivo was observed. Chromatin immunoprecipitation mass spectrometry revealed that the human CAD genome-wide association studies candidate BACH1 (BTB domain and CNC homolog 1) assists MAFF in the presence of lipopolysaccharide stimulation with respective heterodimers binding at the MAF recognition element of the LDLR promoter to transcriptionally downregulate LDLR expression. CONCLUSIONS: The transcription factor MAFF was identified as a novel central regulator of an atherosclerosis/CAD-relevant liver network. MAFF triggered context-specific expression of LDLR and other genes known to affect CAD risk. Our results suggest that MAFF is a missing link between inflammation, lipid and lipoprotein metabolism, and a possible treatment target.

    Acrylamide (ACR), a recognized neurotoxicant in humans and experimental animals, is widely used in industry and in food generated through Maillard reaction. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a master regulator of the cellular defense system and activates antioxidants and cytoprotective genes. The exact roles of Nrf2 in environmental electrophile-induced neurotoxicity is poorly understood. The aim of this study was to determine the roles of Nrf2 in ACR-induced neurotoxicity including degeneration of monoaminergic axons and sensorimotor dysfunction. Male 10-week-old C57BL/6JJcl Nrf2-knockout mice and wild type (WT) counterparts were each divided into four groups of 12 and provided with drinking water containing acrylamide at 0, 67, 110 or 200 ppm for four weeks. The effects of acrylamide were examined by landing foot spread test, immunohistochemistry for noradrenaline (NA) and serotonin (5-HT)-containing axons and Iba1-positive microglia in the prefrontal cortex as well as quantitative real-time polymerase chain reaction (qRT-PCR) on antioxidant, proinflammatory and anti-inflammatory genes in the prefrontal cortex. Relative to the wild type, exposure of Nrf2-knockout mice to acrylamide increased hindlimb splay length, microglial area and process length as well as decreasing the density of NA and 5-HT-immunoreactive axons to a greater extent. Moreover, deletion of Nrf2 gene suppressed acrylamide-induced mRNA upregulation of Nrf2-antioxidants, NAD(P): quinone oxidoreductase 1 (NQO1), superoxide dismutase-1 (SOD-1) and heme oxygenase-1 (HO-1) as well as anti-inflammtory markers such as, arginase-1 (Arg1), found in the inflammatory zone-1 (Fizz1), chitinase-like 3 (Chi3l3), interleukin-4 receptor alpha (IL-4Rα), cluster of differentiation  206 (CD206) and tranforming growth factor beta-1 (TGFβ1) while enhancing acrylamide-induced upregulation of pro-inflammatory cytokines, interleukin-1 beta (IL-1β), tumor necrosis-alpha (TNF-α) and iducible nitric oxide synthase (iNOS) in the prefrontal cortex. The results demonstrate susceptibility of mice lacking the Nrf2 gene to acrylamide-induced neurotoxicity and neuroinflammation with the activation of microglia. Moreover, the results suggest the role of Nrf2 not only in induction of antioxidant gene expression, but also in suppression of proinflammatory cytokine gene expression.

    Traditional observational studies have reported a positive association between higher body mass index (BMI) and the risk of colorectal cancer (CRC). However, evidence from other approaches to pursue the causal relationship between BMI and CRC is sparse. A two-sample Mendelian randomization (MR) study was undertaken using 68 single nucleotide polymorphisms (SNPs) from the Japanese genome-wide association study (GWAS) and 654 SNPs from the GWAS catalogue for BMI as sets of instrumental variables. For the analysis of SNP-BMI associations, we undertook a meta-analysis with 36 303 participants in the Japanese Consortium of Genetic Epidemiology studies (J-CGE), comprising normal populations. For the analysis of SNP-CRC associations, we utilized 7636 CRC cases and 37 141 controls from five studies in Japan, and undertook a meta-analysis. Mendelian randomization analysis of inverse-variance weighted method indicated that a one-unit (kg/m2 ) increase in genetically predicted BMI was associated with an odds ratio of 1.13 (95% confidence interval, 1.06-1.20; P value <.001) for CRC using the set of 68 SNPs, and an odds ratio of 1.07 (1.03-1.11, 0.001) for CRC using the set of 654 SNPs. Sensitivity analyses robustly showed increased odds ratios for CRC for every one-unit increase in genetically predicted BMI. Our MR analyses strongly support the evidence that higher BMI influences the risk of CRC. Although Asians are generally leaner than Europeans and North Americans, avoiding higher BMI seems to be important for the prevention of CRC in Asian populations.

    The transcription nuclear factor-erythroid factor 2-related factor 2 (Nrf2) plays a key role in inflammation that is involved in depression. We previously reported that Nrf2 knock-out (KO) mice exhibit depression-like phenotypes through systemic inflammation. (R)-ketamine, an enantiomer of ketamine, has rapid-acting and long-lasting antidepressant-like effects in rodents. We investigated whether (R)-ketamine can produce antidepressant-like effects in Nrf2 KO mice. Effects of (R)-ketamine on the depression-like phenotypes in Nrf2 KO mice were examined. Furthermore, the role of TrkB in the antidepressant-like actions of (R)-ketamine was also examined. In the tail-suspension test (TST) and forced swimming test (FST), (R)-ketamine (10 mg/kg) significantly attenuated the increased immobility times of TST and FST in the Nrf2 KO mice. In the sucrose preference test (SPT), (R)-ketamine significantly ameliorated the reduced preference of SPT in Nrf2 KO mice. Decreased expression of synaptic proteins (i.e., GluA1 and PSD-95) in the medial prefrontal cortex (mPFC) of Nrf2 KO mice was significantly ameliorated after a single injection of (R)-ketamine. Furthermore, the pre-treatment with the TrkB antagonist ANA-12 (0.5 mg/kg) significantly blocked the rapid and long-lasting antidepressant-like effects of (R)-ketamine in Nrf2 KO mice. Furthermore, ANA-12 significantly antagonized the beneficial effects of (R)-ketamine on decreased expression of synaptic proteins in the mPFC of Nrf2 KO mice. These findings suggest that (R)-ketamine can produce rapid and long-lasting antidepressant-like actions in Nrf2 KO mice via TrkB signaling.

    <italic>FtsJ RNA 2′-O-methyltransferase 1</italic>(<italic>FTSJ1</italic>) gene has been implicated in X-linked intellectual disability (XLID), but the molecular pathogenesis is unknown. We show that Ftsj1 is responsible for 2′-<italic>O</italic>-methylation of 11 species of cytosolic transfer RNAs (tRNAs) at the anticodon region, and these modifications are abolished in Ftsj1 knockout (KO) mice and XLID patient–derived cells. Loss of 2′-<italic>O</italic>-methylation in Ftsj1 KO mouse selectively reduced the steady-state level of tRNAPhein the brain, resulting in a slow decoding at Phe codons. Ribosome profiling showed that translation efficiency is significantly reduced in a subset of genes that need to be efficiently translated to support synaptic organization and functions. Ftsj1 KO mice display immature synaptic morphology and aberrant synaptic plasticity, which are associated with anxiety-like and memory deficits. The data illuminate a fundamental role of tRNA modification in the brain through regulation of translation efficiency and provide mechanistic insights into FTSJ1-related XLID.

    Nuclear factor-erythroid 2-related factor 1 (NFE2L1) is a key transcription factor that regulates cellular adaptive responses to various stresses. Our previous studies revealed that adult adipocyte-specific Nfe2l1-knockout [Nfe2l1(f)-KO] mice show adipocyte hypertrophy and severe adipose inflammation, which can be worsened by rosiglitazone, a peroxisome proliferator-activated receptor γ agonist. To further assess the crucial roles of NFE2L1 in adipocytes, we investigated the effect of CL316243, a β3 adrenergic agonist that promotes lipolysis via a post-translational mechanism, on adipose inflammation in juvenile Nfe2l1(f)-KO mice. In contrast to adult mice, 4-week-old juvenile Nfe2l1(f)-KO mice displayed a normal fat distribution but reduced fasting plasma glycerol levels and elevated adipocyte hypertrophy and macrophage infiltration in inguinal and gonadal WAT. In addition, Nfe2l1(f)-KO mice had decreased expression of multiple lipolytic genes and reduced lipolytic activity in WAT. While 7 days of CL316243 treatment showed no significant effect on adipose inflammation in Nfe2l1-Floxed control mice, the same treatment dramatically alleviated macrophage infiltration and mRNA expression of inflammation and pyroptosis-related genes in WAT of Nfe2l1(f)-KO mice. Together with previous findings in adult mice, the current study highlights that NFE2L1 plays a fundamental regulatory role in lipolytic gene expression and thus might be an important target to improve adipose plasticity and lipid homeostasis.

    <title>Abstract</title>Primary open-angle glaucoma (POAG), is a heritable common cause of blindness world-wide. To identify risk loci, we conduct a large multi-ethnic meta-analysis of genome-wide association studies on a total of 34,179 cases and 349,321 controls, identifying 44 previously unreported risk loci and confirming 83 loci that were previously known. The majority of loci have broadly consistent effects across European, Asian and African ancestries. Cross-ancestry data improve fine-mapping of causal variants for several loci. Integration of multiple lines of genetic evidence support the functional relevance of the identified POAG risk loci and highlight potential contributions of several genes to POAG pathogenesis, including <italic>SVEP1, RERE, VCAM1, ZNF638</italic>, <italic>CLIC5, SLC2A12, YAP1, MXRA5</italic>, and <italic>SMAD6</italic>. Several drug compounds targeting POAG risk genes may be potential glaucoma therapeutic candidates.

    Pancreatic cancer remains intractable owing to the lack of effective therapy for unresectable cases. Activating mutations of K-ras are frequently found in pancreatic cancers, but these have not yet been targeted by cancer therapies. The Keap1-Nrf2 system plays a crucial role in mediating the oxidative stress response, which also contributes to cancer progression. Nrf2 activation reprograms the metabolic profile to promote the proliferation of cancer cells. A recent report suggested that K-ras- and Nrf2-active lung cancer cells are sensitive to glutamine depletion. This finding led to the recognition of glutaminase inhibitors as novel anticancer agents. In the current study, we used murine pancreatic cancer tissues driven by mutant K-ras and p53 to establish cell lines expressing constitutively activated Nrf2. Genetic or pharmacological Nrf2 activation in cells via Keap1 deletion or Nrf2 activation sensitized cells to glutaminase inhibition. This phenomenon was confirmed to be dependent on K-ras activation in human pancreatic cancer cell lines harboring mutant K-ras, i.e., Panc-1 and MiaPaCa-2 in response to DEM pretreatment. This phenomenon was not observed in BxPC3 cells harboring wildtype K-ras. These results indicate the possibility of employing Nrf2 activation and glutaminase inhibition as novel therapeutic interventions for K-ras mutant pancreatic cancers.

    Activating mutations in the KEAP1-NRF2 pathway are found in approximately 25% of lung tumors, where the hijacking of NRF2's cytoprotective functions results in aggressive tumor growth, chemoresistance, and a poor prognosis for patients. There are currently no approved drugs which target aberrant NRF2 activation, which means that there is an urgent clinical need to target this orphan oncogenic pathway in human tumors. In this study, we used an isogenic pair of wild-type and Keap1 knockout cells to screen a range of chemotherapeutic and pathway-targeted anticancer drugs in order to identify compounds which display enhanced toxicity toward cells with high levels of Nrf2 activity. Through this approach, complemented by validation across a panel of eight human cancer cell lines from a range of different tissues, we identified the DNA-damaging agent mitomycin C to be significantly more toxic in cells with aberrant Nrf2 activation. Mechanistically, we found that the NRF2 target genes for cytochrome P450 reductase, NQO1, and enzymes in the pentose phosphate pathway are all responsible for the NRF2-dependent enhanced bioactivation of mitomycin C. As mitomycin C is already approved for clinical use, it represents as excellent drug repositioning candidate to target the currently untreatable NRF2 activation in human tumors.

    Our body responds to environmental stress by changing the expression levels of a series of cytoprotective enzymes/proteins through multilayered regulatory mechanisms, including the KEAP1-NRF2 system. While NRF2 upregulates the expression of many cytoprotective genes, there are fundamental limitations in short-read RNA sequencing (RNA-Seq), resulting in confusion regarding interpreting the effectiveness of cytoprotective gene induction at the transcript level. To precisely delineate isoform usage in the stress response, we conducted independent full-length transcriptome profiling (isoform sequencing; Iso-Seq) analyses of lymphoblastoid cells from three volunteers under normal and electrophilic stress-induced conditions. We first determined the first exon usage in KEAP1 and NFE2L2 (encoding NRF2) and found the presence of transcript diversity. We then examined changes in isoform usage of NRF2 target genes under stress conditions and identified a few isoforms dominantly expressed in the majority of NRF2 target genes. The expression levels of isoforms determined by Iso-Seq analyses showed striking differences from those determined by short-read RNA-Seq; the latter could be misleading concerning the abundance of transcripts. These results support that transcript usage is tightly regulated to produce functional proteins under electrophilic stress. Our present study strongly argues that there are important benefits that can be achieved by long-read transcriptome sequencing.

    Nrf2 is essential for cytoprotection against carcinogens, and through systemic Nrf2 knockout mice, Nrf2-deficient cells were shown to be susceptible to chemical carcinogens and prone to developing cancers. However, the oncogenic potential of Nrf2-deficient epithelial cells surrounded by normal cells in the esophagus could not be assessed by previous models, and the fate of Nrf2-deficient cells in such situations remains elusive. In this study, therefore, we generated mice that harbor almost equal levels of cells with Nrf2 deleted and those with Nrf2 intact in the basal layer of the esophageal epithelium, utilizing inducible Cre-mediated recombination of Nrf2 alleles in adults through moderate use of tamoxifen. In this mouse model, epithelial cells with Nrf2 deleted were maintained with no obvious decrease or phenotypic changes for 12 weeks under unstressed conditions. Upon exposure to the carcinogen 4-nitroquinoline-1-oxide (4NQO), the cells with Nrf2 deleted accumulated DNA damage and selectively disappeared from the epithelium, so almost all 4NQO-induced tumors originated from cells with Nrf2 intact and not from those with Nrf2 deleted. We propose that cells with Nrf2 deleted do not undergo carcinogenesis due to selective elimination upon exposure to 4NQO, indicating that cellular Nrf2 abundance and the epithelial environment determine the cell fate or oncogenic potential of esophageal epithelial cells in 4NQO-induced carcinogenesis.

    Bone dysplasias are a group of rare hereditary diseases, with up to 436 disease types. Perinatal diagnosis is clinically important for adequate personalized management and counseling. There are no reports focused on pathogenic variants of bone dysplasias in the general population. In this study, we focused on autosomal recessive bone dysplasias. We identified pathogenic variants using whole-genome reference panel data from 3552 Japanese individuals. For the first time, we were able to estimate the carrier frequencies and the proportions of potential patients. For autosomal recessive bone dysplasias, we detected 198 pathogenic variants of 54 causative genes. We estimated the variant carrier frequencies and the proportions of potential patients with variants associated with four clinically important bone dysplasias: osteogenesis imperfecta (OI), hypophosphatasia (HPP), asphyxiating thoracic dysplasia (ATD), and Ellis-van Creveld syndrome (EvC). The proportions of potential patients with OI, ATD, and EvC based on pathogenic variants classified as "pathogenic" and "likely pathogenic" by InterVar were closer to the reported incidence rates in Japanese subjects. Furthermore, the proportions of potential patients with HPP variants classified as "pathogenic" and "likely pathogenic" in InterVar and "pathogenic" in ClinVar were closer to the reported incidence rates. For bone dysplasia, the findings of this study will provide a better understanding of the variant types and frequencies in the Japanese general population, and should be useful for clinical diagnosis, genetic counseling, and personalized medicine.

    <title>ABSTRACT</title>The complete sequence of the human genome is used as a reference for next-generation sequencing analyses. However, some ethnic ancestries are under-represented in the international human reference genome (e.g., GRCh37), especially Asian populations, due to a strong bias toward European and African ancestries in a single mosaic haploid genome consisting chiefly of a single donor. Here, we performed <italic>de novo</italic> assembly of the genomes from three Japanese male individuals using &gt;100× PacBio long reads and Bionano optical maps per sample. We integrated the genomes using the major allele for consensus, and anchored the scaffolds using sequence-tagged site markers from conventional genetic and radiation hybrid maps to reconstruct each chromosome sequence. The resulting genome sequence, designated JG1, is highly contiguous, accurate, and carries the major allele in the majority of single nucleotide variant sites for a Japanese population. We adopted JG1 as the reference for confirmatory exome re-analyses of seven Japanese families with rare diseases and found that re-analysis using JG1 reduced false-positive variant calls versus GRCh37 while retaining disease-causing variants. These results suggest that integrating multiple genome assemblies from a single ethnic population can aid next-generation sequencing analyses of individuals originated from the population.

    In the Tohoku Medical Megabank project, genome and omics analyses of participants in two cohort studies were performed. A part of the data is available at the Japanese Multi Omics Reference Panel (jMorp; https://jmorp.megabank.tohoku.ac.jp) as a web-based database, as reported in our previous manuscript published in Nucleic Acid Research in 2018. At that time, jMorp mainly consisted of metabolome data; however, now genome, methylome, and transcriptome data have been integrated in addition to the enhancement of the number of samples for the metabolome data. For genomic data, jMorp provides a Japanese reference sequence obtained using de novo assembly of sequences from three Japanese individuals and allele frequencies obtained using whole-genome sequencing of 8,380 Japanese individuals. In addition, the omics data include methylome and transcriptome data from ∼300 samples and distribution of concentrations of more than 755 metabolites obtained using high-throughput nuclear magnetic resonance and high-sensitivity mass spectrometry. In summary, jMorp now provides four different kinds of omics data (genome, methylome, transcriptome, and metabolome), with a user-friendly web interface. This will be a useful scientific data resource on the general population for the discovery of disease biomarkers and personalized disease prevention and early diagnosis.

    Novel antiviral agents for influenza, which poses a substantial threat to humans, are required. Cyclobakuchiols A and B have been isolated from Psoralea glandulosa, and cyclobakuchiol C has been isolated from P. corylifolia. The structural differences between cyclobakuchiol A and C arise due to the oxidation state of isopropyl group, and these compounds can be derived from (+)-(S)-bakuchiol, a phenolic isoprenoid compound present in P. corylifolia seeds. We previously reported that bakuchiol induces enantiospecific anti-influenza A virus activity involving nuclear factor erythroid 2-related factor 2 (Nrf2) activation. However, it remains unclear whether cyclobakuchiols A-C induce anti-influenza A virus activity. In this study, cyclobakuchiols A, B, and C along with cyclobakuchiol D, a new artificial compound derived from cyclobakuchiol B, were synthesized and examined for their anti-influenza A virus activities using Madin-Darby canine kidney cells. As a result, cyclobakuchiols A-D were found to inhibit influenza A viral infection, growth, and the reduction of expression of viral mRNAs and proteins in influenza A virus-infected cells. Additionally, these compounds markedly reduced the mRNA expression of the host cell influenza A virus-induced immune response genes, interferon-β and myxovirus-resistant protein 1. In addition, cyclobakuchiols A-D upregulated the mRNA levels of NAD(P)H quinone oxidoreductase 1, an Nrf2-induced gene, in influenza A virus-infected cells. Notably, cyclobakuchiols A, B, and C, but not D, induced the Nrf2 activation pathway. These findings demonstrate that cyclobakuchiols have anti-influenza viral activity involving host cell oxidative stress response. In addition, our results suggest that the suitably spatial configuration between oxidized isopropyl group and phenol moiety in the structure of cyclobakuchiols is required for their effect.

    In this study, the extent to which different emotions of pregnant women can be predicted based on heart rate-relevant information as indicators of autonomic nervous system functioning was explored using various machine learning algorithms. Nine heart rate-relevant autonomic system indicators, including the coefficient of variation R-R interval (CVRR), standard deviation of all NN intervals (SDNN), and square root of the mean squared differences of successive NN intervals (RMSSD), were measured using a heart rate monitor (MyBeat) and four different emotions including "happy," as a positive emotion and "anxiety," "sad," "frustrated," as negative emotions were self-recorded on a smartphone application, during 1 week starting from 23rd to 32nd weeks of pregnancy from 85 pregnant women. The k-nearest neighbor (k-NN), support vector machine (SVM), logistic regression (LR), random forest (RF), naïve bayes (NB), decision tree (DT), gradient boosting trees (GBT), stochastic gradient descent (SGD), extreme gradient boosting (XGBoost), and artificial neural network (ANN) machine learning methods were applied to predict the four different emotions based on the heart rate-relevant information. To predict four different emotions, RF also showed a modest area under the receiver operating characteristic curve (AUC-ROC) of 0.70. CVRR, RMSSD, SDNN, high frequency (HF), and low frequency (LF) mostly contributed to the predictions. GBT displayed the second highest AUC (0.69). Comprehensive analyses revealed the benefits of the prediction accuracy of the RF and GBT methods and were beneficial to establish models to predict emotions based on autonomic nervous system indicators. The results implicated SDNN, RMSSD, CVRR, LF, and HF as important parameters for the predictions.

    The purpose of the present study was to identify a plasma protein biomarker able to predict pre-eclampsia (PE). Comprehensive quantitative proteomics using mass spectrometry with sequential window acquisition of all theoretical fragment ion spectra (SWATH-MS) was applied to plasma samples of 7 PE and 14 healthy pregnant women (for PE subjects, plasma samples were taken before onset of PE), and 11 proteins were selected as candidates potentially able to differentiate the two groups. Plasmas collected at gestational weeks 14-24 from 36 PE and 120 healthy pregnant women (for PE subjects, plasma samples were taken before onset of PE) were used to conduct selected reaction monitoring quantification analysis, optimize protein combinations and conduct internal validation, which consisted of 30 iterations of 10-fold cross-validation using multivariate logistic regression and receiver operating characteristic (ROC) analysis. The combination of afamin, fibronectin, and sex-hormone-binding globulin was selected as the best candidate. The 3-protein combination predictive model (predictive equation and cut-off value) generated using the internal validation subjects was successfully validated in another group of validation subjects (36 PE and 54 healthy (for PE subjects, plasma samples were taken before onset of PE)) and showed good predictive performance, with the area under the curve (AUC) 0.835 and odds ratio 13.43. In conclusion, we newly identified a 3-protein combination biomarker and established a predictive equation and cut-off value that can predict the onset of PE based on analysis of plasma samples collected during gestational weeks 14-24.

    Identification of the population frequencies of definitely pathogenic germline variants in two major hereditary breast and ovarian cancer syndrome (HBOC) genes, BRCA1/2, is essential to estimate the number of HBOC patients. In addition, the identification of moderately penetrant HBOC gene variants that contribute to increasing the risk of breast and ovarian cancers in a population is critical to establish personalized health care. A prospective cohort subjected to genome analysis can provide both sets of information. Computational scoring and prospective cohort studies may help to identify such likely pathogenic variants in the general population. We annotated the variants in the BRCA1 and BRCA2 genes from a dataset of 3,552 whole-genome sequences obtained from members of a prospective cohorts with genome data in the Tohoku Medical Megabank Project (TMM) with InterVar software. Computational impact scores (CADD_phred and Eigen_raw) and minor allele frequencies (MAFs) of pathogenic (P) and likely pathogenic (LP) variants in ClinVar were used for filtration criteria. Familial predispositions to cancers among the 35,000 TMM genome cohort participants were analyzed to verify the identified pathogenicity. Seven potentially pathogenic variants were newly identified. The sisters of carriers of these moderately deleterious variants and definite P and LP variants among members of the TMM prospective cohort showed a statistically significant preponderance for cancer onset, from the self-reported cancer history. Filtering by computational scoring and MAF is useful to identify potentially pathogenic variants in BRCA genes in the Japanese population. These results should help to follow up the carriers of variants of uncertain significance in the HBOC genes in the longitudinal prospective cohort study.

    The Kelch-like ECH-associated protein (KEAP1)- Nuclear factor erythroid-derived 2-like 2 (encoded by the Nfe2l2 gene; NRF2) system attracts extensive interest from scientists in basic and clinical cancer research fields, as NRF2 exhibits activity as both an oncogene and tumor suppressor, depending on the context. Especially unique and malignant, NRF2-addicted cancers exhibit high levels of NRF2 expression. Somatic mutations identified in the NRF2 or KEAP1 genes of NRF2-addicted cancers cause the stabilization and accumulation of NRF2. NRF2-addicted cancers hijack the intrinsic roles that NRF2 plays in cytoprotection, including antioxidative and anti-electrophilic responses, as well as metabolic reprogramming, and acquire a marked advantage to survive under severe and limited microenvironments. Therefore, NRF2 inhibitors are expected to have therapeutic effects in patients with NRF2-addicted cancers. In contrast, NRF2 activation in host immune cells exerts significant suppression of cancer cell growth, indicating that NRF2 inducers also have the potential to be therapeutics for cancers. Thus, the KEAP1-NRF2 system makes a broad range of contributions to both cancer development and suppression. These observations thus demonstrate that both NRF2 inhibitors and inducers are useful for the treatment of cancers with high NRF2 activity.

    The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) regulates the expression of genes involved in antioxidant defenses to modulate fundamental cellular processes such as mitochondrial function and glutathione metabolism. Previous reports proposed that mitochondrial ROS production and disruption of the glutathione pool activate the Nrf2 pathway, suggesting that Nrf2 senses mitochondrial redox signals and/or oxidative damage and signals to the nucleus to respond appropriately. However, until now it has not been possible to disentangle the overlapping effects of mitochondrial superoxide/ hydrogen peroxide production as a redox signal from changes to mitochondrial thiol homeostasis on Nrf2. Recently, we developed mitochondria-targeted reagents that can independently induce mitochondrial superoxide and hydrogen peroxide production (MitoPQ), or selectively disrupt mitochondrial thiol homeostasis (MitoCDNB). Using these reagents, here we have determined how enhanced generation of mitochondrial superoxide and hydrogen peroxide, or disruption of mitochondrial thiol homeostasis affect activation of the Nrf2 system in cells, which was assessed by Nrf2 protein level, nuclear translocation and expression of its target genes. We found that selective disruption of the mitochondrial glutathione pool and inhibition of its thioredoxin system by MitoCDNB led to Nrf2 activation, while using MitoPQ to enhance production of mitochondrial superoxide and hydrogen peroxide alone did not. We further showed that Nrf2 activation by MitoCDNB requires cysteine sensors of Kelch-like ECH-associated protein 1 (Keap1). These findings provide important information on how disruption to mitochondrial redox homeostasis is sensed in the cytoplasm and signaled to the nucleus.

    The kidneys are the major organs for erythropoietin (EPO) production in adults, and thus, kidney damage results in reduced EPO levels and anemia. Inhibitors of Hypoxia-inducible factor-prolyl hydroxylase domain-containing protein (HIF-PHD) are awaited as new therapeutic options for renal anemia. It can be predicted that most patients who receive HIF-PHD inhibitors have renal dysfunction as a cause of anemia. Therefore, in the present study, we investigated the effects of the HIF-PHD inhibitor molidustat on anemia and renal dysfunction when initiated after the onset of renal anemia. Male C57BL/6J mice received adenine orally to induce nephropathy. After the onset of nephropathy, the mice were treated with either vehicle or molidustat. After 4 weeks of administration, vehicle-treated mice displayed significant anemia, and molidustat ameliorated this anemia. Vehicle-treated mice exhibited reduced creatinine clearance and body weight, increased blood urea nitrogen levels, histopathological changes, immune cell infiltration, and dehydration. Molidustat reversed immune cell infiltration, dehydration, and renal fibrosis without improving renal functional parameters. In conclusion, molidustat treatment initiated after the onset of nephropathy and renal anemia reversed anemia in mice. Molidustat improved some parameters of renal abnormality, but it did not restore renal function.

    <title>Abstract</title> We performed a metabolome genome-wide association study for the Japanese population in the prospective cohort study of Tohoku Medical Megabank. By combining whole-genome sequencing and nontarget metabolome analyses, we identified a large number of novel associations between genetic variants and plasma metabolites. Of the identified metabolite-associated genes, approximately half have already been shown to be involved in various diseases. We identified metabolite-associated genes involved in the metabolism of xenobiotics, some of which are from intestinal microorganisms, indicating that the identified genetic variants also markedly influence the interaction between the host and symbiotic bacteria. We also identified five associations that appeared to be female-specific. A number of rare variants that influence metabolite levels were also found, and combinations of common and rare variants influenced the metabolite levels more profoundly. These results support our contention that metabolic phenotyping provides important insights into how genetic and environmental factors provoke human diseases.

    Human lymphoblastoid cell lines (LCLs) are valuable for the functional analyses of diseases. We have established more than 4200 LCLs as one of the resources of an integrated biobank. While oxidative and inflammatory stresses play critical roles in the onset and progression of various diseases, the responsiveness of LCLs, especially that of biobank-made LCLs, to these stresses has not been established. To address how LCLs respond to these stresses, in this study, we performed RNA sequencing of eleven human LCLs that were treated with an electrophile, diethyl maleate (DEM) and/or an inflammatory mediator, lipopolysaccharide (LPS). We found that over two thousand genes, including those regulated by a master regulator of the electrophilic/oxidative stress response, NRF2, were upregulated in LCLs treated with DEM, while approximately three hundred genes, including inflammation-related genes, were upregulated in LPS-treated LCLs. Of the LPS-induced genes, a subset of proinflammatory genes was repressed by DEM, supporting the notion that DEM suppresses the expression of proinflammatory genes through NRF2 activation. Conversely, a part of DEM-induced gene was repressed by LPS, suggesting reciprocal interference between electrophilic and inflammatory stress-mediated pathways. These data clearly demonstrate that LCLs maintain, by and large, responsive pathways against oxidative and inflammatory stresses and further endorse the usefulness of the LCL supply from the biobank.

    Environmental pollution is one of the most serious challenges to health in the modern world. Pollutants alter immune responses and can provoke immunotoxicity. In this Review, we summarize the major environmental pollutants that are attracting wide-ranging concern and the molecular basis underlying their effects on the immune system. Xenobiotic receptors, including the aryl hydrocarbon receptor (AHR), sense and respond to a subset of environmental pollutants by activating the expression of detoxification enzymes to protect the body. However, chronic activation of the AHR leads to immunotoxicity. KEAP1-NRF2 is another important system that protects the body against environmental pollutants. KEAP1 is a sensor protein that detects environmental pollutants, leading to activation of the transcription factor NRF2. NRF2 protects the body from immunotoxicity by inducing the expression of genes involved in detoxification, antioxidant and anti-inflammatory activities. Intervening in these sensor-response systems could protect the body from the devastating immunotoxicity that can be induced by environmental pollutants.

    Research on astronaut health and model organisms have revealed six features of spaceflight biology that guide our current understanding of fundamental molecular changes that occur during space travel. The features include oxidative stress, DNA damage, mitochondrial dysregulation, epigenetic changes (including gene regulation), telomere length alterations, and microbiome shifts. Here we review the known hazards of human spaceflight, how spaceflight affects living systems through these six fundamental features, and the associated health risks of space exploration. We also discuss the essential issues related to the health and safety of astronauts involved in future missions, especially planned long-duration and Martian missions.

    Transcriptional dysregulation, which can be caused by genetic and epigenetic alterations, is a fundamental feature of many cancers. A key cytoprotective transcriptional activator, NRF2, is often aberrantly activated in non-small cell lung cancers (NSCLCs) and supports both aggressive tumorigenesis and therapeutic resistance. Herein, we find that persistently activated NRF2 in NSCLCs generates enhancers at gene loci that are not normally regulated by transiently activated NRF2 under physiological conditions. Elevated accumulation of CEBPB in NRF2-activated NSCLCs is found to be one of the prerequisites for establishment of the unique NRF2-dependent enhancers, among which the NOTCH3 enhancer is shown to be critical for promotion of tumor-initiating activity. Enhancer remodeling mediated by NRF2-CEBPB cooperativity promotes tumor-initiating activity and drives malignancy of NRF2-activated NSCLCs via establishment of the NRF2-NOTCH3 regulatory axis.

    Preeclampsia is a pregnancy-induced disorder that is characterized by hypertension and is a leading cause of perinatal and maternal-fetal morbidity and mortality. HLA-G is thought to play important roles in maternal-fetal immune tolerance, and the associations between HLA-G gene polymorphisms and the onset of pregnancy-related diseases have been explored extensively. Because contiguous genomic sequencing is difficult, the association between the HLA-G genotype and preeclampsia onset is controversial. In this study, genomic sequences of the HLA-G region (5.2 kb) from 31 pairs of mother-offspring genomic DNA samples (18 pairs from normal pregnancies/births and 13 from preeclampsia births) were obtained by single-molecule real-time sequencing using the PacBio RS II platform. The HLA-G alleles identified in our cohort matched seven known HLA-G alleles, but we also identified two new HLA-G alleles at the fourth-field resolution and compared them with nucleotide sequences from a public database that consisted of coding sequences that cover the 3.1-kb HLA-G gene span. Intriguingly, a potential association between preeclampsia onset and the poly T stretch within the downstream region of the HLA-G*01:01:01:01 allele was found. Our study suggests that long-read sequencing of HLA-G will provide clues for characterizing HLA-G variants that are involved in the pathophysiology of preeclampsia.

    Bronchopulmonary dysplasia (BPD) is a chronic disease of preterm babies with poor clinical outcomes. Nrf2 transcription factor is crucial for cytoprotective response, whereas Keap1-an endogenous inhibitor of Nrf2 signaling-dampens these protective responses. Nrf2-sufficient (wild type) newborn mice exposed to hyperoxia develop hypoalveolarization, which phenocopies human BPD, and Nrf2 deficiency worsens it. In this study, we used PND1 pups bearing bearing hypomorphic Keap1 floxed alleles (Keap1f/f) with increased levels of Nrf2 to test the hypothesis that constitutive levels of Nrf2 in the premature lung are insufficient to mitigate hyperoxia-induced hypoalveolarization. Both wildtype and Keap1f/f pups at PND1 were exposed to hyperoxia for 72 h and then allowed to recover at room air for two weeks (at PND18), sacrificed, and lung hypoalveolarization and inflammation assessed. Hyperoxia-induced lung hypoalveolarization was remarkably lower in Keap1f/f pups than in wildtype counterparts (28.9% vs 2.4%, wildtype vs Keap1f/f). Likewise, Keap1f/f pups were protected against prolonged (96 h) hyperoxia-induced hypoalveolarization. However, there were no differences in hyperoxia-induced lung inflammatory response immediately after exposure or at PND18. Lack of hypoalveolarization in Keap1f/f pups was accompanied by increased levels of expression of antioxidant genes and GSH as assessed immediately following hyperoxia. Keap1 knockdown resulted in upregulation of lung cell proliferation postnatally but had opposing effects following hyperoxia. Collectively, our study demonstrates that augmenting endogenous Nrf2 activation by targeting Keap1 may provide a physiological way to prevent hypoalveolarization associated with prematurity.

    Activating mutations in KEAP1-NRF2 are frequently found in tumors of the lung, esophagus, and liver, where they are associated with aggressive growth, resistance to cancer therapies, and low overall survival. Despite the fact that NRF2 is a validated driver of tumorigenesis and chemotherapeutic resistance, there are currently no approved drugs which can inhibit its activity. Therefore, there is an urgent clinical need to identify NRF2-selective cancer therapies. To this end, we developed a novel synthetic lethal assay, based on fluorescently labeled isogenic wild-type and Keap1 knockout cell lines, in order to screen for compounds which selectively kill cells in an NRF2-dependent manner. Through this approach, we identified three compounds based on the geldanamycin scaffold which display synthetic lethality with NRF2. Mechanistically, we show that products of NRF2 target genes metabolize the quinone-containing geldanamycin compounds into more potent HSP90 inhibitors, which enhances their cytotoxicity while simultaneously restricting the synthetic lethal effect to cells with aberrant NRF2 activity. As all three of the geldanamycin-derived compounds have been used in clinical trials, they represent ideal candidates for drug repositioning to target the currently untreatable NRF2 activity in cancer.

    In the present study, we investigated the role of Nrf2 in airway immune responses induced by diesel exhaust (DE) inhalation in mice. C57BL/6J Nrf2+/+ and Nrf2-/- mice were exposed to DE or clean air for 8 h/day and 6 days/week for 4 weeks. After DE exposure, the number of neutrophils and macrophage inflammatory protein (MIP)-2 level in bronchoalveolar lavage fluid (BALF) and interleukin (IL)-17 level in the lung tissue increased in Nrf2-/- mice compared with Nrf2+/+ mice; however, the lack of an increase in the level of tumor necrosis factor (TNF)-α in the lung tissue in Nrf2+/+ mice and mild suppression of the level of TNF-α in Nrf2-/- mice were observed; the level of granulocyte macrophage colony-stimulating factor (GM-CSF) in the lung tissue decreased in Nrf2-/- mice than in Nrf2+/+ mice; the number of DE particle-laden alveolar macrophages in BALF were larger in Nrf2-/- mice than in Nrf2+/+ mice. The results of electron microscope observations showed alveolar type II cell injury and degeneration of the lamellar body after DE exposure in Nrf2-/- mice. Antioxidant enzyme NAD(P)H quinone dehydrogenase (NQO)1 mRNA expression level was higher in Nrf2+/+ mice than in Nrf2-/- mice after DE exposure. Our results suggested that Nrf2 reduces the risk of pulmonary disease via modulating the airway innate immune response caused by DE in mice.

    BACKGROUND: The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study was launched in 2013 to evaluate the complex interactions of genetic and environmental factors in multifactorial diseases. The present study describes the maternal baseline profile and perinatal data of participating mothers and infants. METHODS: Expectant mothers living in Miyagi prefecture were recruited from obstetric facilities or affiliated centers between 2013 and 2017. Three sets of self-administered questionnaires were collected, and the medical records were reviewed to obtain precise information about each antenatal visit and each delivery. Biospecimens, including blood, urine, umbilical cord blood, and breast milk, were collected for the study biobank. The baseline maternal sociodemographic characteristics, results of screening tests, and obstetric outcomes were analyzed according to the maternal age group. RESULTS: A total of 23 406 pregnancies involving 23 730 fetuses resulted in 23 143 live births. Younger maternal participants had a tendency toward a higher incidence of threatened abortion and threatened premature labor, while older age groups exhibited a significantly higher rate of low lying placenta, placenta previa, gestational diabetes and hypertensive disorders of pregnancy. CONCLUSIONS: The present study clearly shows the distribution of maternal baseline characteristics and the range of perinatal outcomes according to maternal age group. This cohort study can provide strategic information for creating breakthroughs in the pathophysiology of perinatal, developmental, and noncommunicable diseases by collaborative data visiting or sharing.

    Space flight produces an extreme environment with unique stressors, but little is known about how our body responds to these stresses. While there are many intractable limitations for in-flight space research, some can be overcome by utilizing gene knockout-disease model mice. Here, we report how deletion of Nrf2, a master regulator of stress defense pathways, affects the health of mice transported for a stay in the International Space Station (ISS). After 31 days in the ISS, all flight mice returned safely to Earth. Transcriptome and metabolome analyses revealed that the stresses of space travel evoked ageing-like changes of plasma metabolites and activated the Nrf2 signaling pathway. Especially, Nrf2 was found to be important for maintaining homeostasis of white adipose tissues. This study opens approaches for future space research utilizing murine gene knockout-disease models, and provides insights into mitigating space-induced stresses that limit the further exploration of space by humans.

    The transcription factor Nrf2 activates transcription of cytoprotective genes during oxidative and electrophilic insults. Nrf2 activity is regulated by Keap1 in a stress-dependent manner in normal cells, and somatic loss-of-function mutations of Keap1 are known to induce constitutive Nrf2 activation, especially in lung adenocarcinomas, conferring survival and proliferative benefits to tumors. Therefore, several therapeutic strategies that aim to inhibit Nrf2 in tumors have been developed for the treatment of Nrf2-activated cancers. Here we addressed whether targeting Nrf2 activation in the microenvironment can suppress the progression of Nrf2-activated tumors. We combined two types of Keap1-flox mice expressing variable levels of Keap1 with a Kras-driven adenocarcinoma model to generate Keap1-deficient lung tumors surrounded by normal or Keap1-knockdown host cells. In this model system, activation of Nrf2 in the microenvironment prolonged the survival of Nrf2-activated tumor-bearing mice. The Nrf2-activated microenvironment suppressed tumor burden; in particular, preinvasive lesion formation was significantly suppressed. Notably, loss of Nrf2 in bone marrow-derived cells in Nrf2-activated host cells appeared to counteract the suppression of Nrf2-activated cancer progression. Thus, these results demonstrate that microenvironmental Nrf2 activation suppresses the progression of malignant Nrf2-activated tumors and that Nrf2 activation in immune cells at least partially contributes to these suppressive effects. SIGNIFICANCE: This study clarifies the importance of Nrf2 activation in the tumor microenvironment and in the host for the suppression of malignant Nrf2-activated cancers and proposes new cancer therapies utilizing inducers of Nrf2.

    Low birth weight is known to be associated with hypertension, cardiovascular disease and hypertensive disorders of pregnancy (HDP); however, this association might vary by race/ethnicity. This study aimed to clarify the association between women's own birth weight and their subsequent risk for HDP in a Japanese population, in combination with pre-pregnancy body mass index (BMI). We conducted a cohort study as part of the Tohoku Medical Megabank Birth and Three-Generation Cohort Study in Miyagi, Japan. Our study's population included 4810 women. A multivariate logistic regression analysis was performed to calculate the adjusted odds ratio (aOR) and the 95% confidence interval (CI) of the women's own birth weight for HDP, in the combination categories of birth weight and pre-pregnancy BMI. As a result, the group with a low birth weight of <2500 g had a significant association with HDP (the aOR, 1.50; 95% CI, 1.02-2.21). In the subtype analysis, the odds ratio for only preeclampsia was significantly increased in the low birth weight group (aOR, 3.37; 95% CI, 1.84-6.16). In the group with a low birth weight, the prevalence of HDP was higher in both the underweight and overweight groups. In conclusion, there was a significant association between low birth weight and subsequent HDP in Japanese women. Furthermore, a significant association with HDP was found for women born with a low birth weight who were underweight or overweight as adults. Maintaining a normal weight may be effective for preventing HDP even if a woman was born small.

    NF-E2-related factor 2 (Nrf2) is a transcriptional regulator of biologic defense proteins, such as antioxidant proteins and phase II detoxification enzymes. Cytochrome P450 (P450) enzymes have been shown to regulate phase I metabolism of various drugs and are partially regulated by Nrf2; however, the influence of Nrf2 on drug pharmacokinetics is not known. Here, we showed that Nrf2 depletion prolonged the effect of pentobarbital, a sleep-promoting drug. Pretreatment with phenobarbital, a P450 inducer, shortens the sleeping time associated with pentobarbital-induced sedation in wild-type (WT) mice; however, this effect was not observed in Nrf2-/- mice. Furthermore, the blood pentobarbital concentration was higher in Nrf2-/- mice than in WT mice at 30-60 minutes, and the phenobarbital-induced enhancement of its clearance was attenuated in Nrf2-/- mice compared with WT mice. Total P450 content was decreased in Nrf2-/- mouse livers, and the phenobarbital-induced increase in P450 content was lower in Nrf2-/- mice than WT mice. Cyp1a2, Cyp2a5, Cyp2c29, and Cyp2e1 gene expression levels under physiologic conditions and Cyp1a2, Cyp2a5, and Cyp2b10 gene expression levels under phenobarbital-treated conditions were lower in Nrf2-/- mice compared with WT mice. Additionally, pentobarbital metabolism in liver microsomes was attenuated by Nrf2 depletion. Taken together, these findings suggested that Nrf2 influenced pentobarbital pharmacokinetics through the regulation of drug metabolism and P450 gene expression. Thus, Nrf2-mediated regulation of P450 may contribute to the biologic defense against increased reactive oxygen species production. SIGNIFICANCE STATEMENT: NF-E2-related factor 2 (Nrf2) plays a critical role in the cellular defense against oxidative stress. Nrf2-/- mice with reduced ability to eliminate reactive oxygen species (ROS) showed a significant delay in emergence from pentobarbital-induced sleep, which was associated with decreased P450 activities and gene expression. Our findings provide that Nrf2 dysfunction or ROS that exceed a threshold level of the eliminating ability of the Nrf2 system may reduce P450 activity.

    <title>Abstract</title>Identification of pathogenic germline variants yet no clinical evidence in <italic>BRCA</italic> genes has become important in patient care of hereditary breast and ovarian cancer syndrome (HBOC). Computational scoring and prospective cohort studies may help to identify such pathogenic variants. We annotated the variants in the <italic>BRCA1</italic> and <italic>BRCA2</italic> genes from a dataset of 3,552 whole-genome sequences obtained from members of the genome cohorts by Tohoku Medical Megabank Project (TMM) with the InterVar software. Computational impact scores (CADD_phred and Eigen_raw) and minor allele frequencies (MAF) of pathogenic (P) and likely pathogenic (LP) variants in ClinVar are used for filtration criteria. Familial predispositions in cancers among the 35,000 TMM genome cohort participants are analyzed to verify the pathogenicity. Seven potentially pathogenic variants were newly identified. Carriers of these potential pathogenic variants and definite P and LP variants among participants of the TMM prospective cohort show a statistically significant preponderance in cancer onset in sisters in the self-reported cancer history. Filtering by computational scoring and MAF is useful to identify potential pathogenic variants in <italic>BRCA</italic> genes for Japanese population. These results will be helpful to follow up the carriers of variants of uncertain significance in the HBOC genes.

    The KEAP1-NRF2 pathway is the principal protective response to oxidative and electrophilic stresses. Under homeostatic conditions, KEAP1 forms part of an E3 ubiquitin ligase, which tightly regulates the activity of the transcription factor NRF2 by targeting it for ubiquitination and proteasome-dependent degradation. In response to stress, an intricate molecular mechanism facilitated by sensor cysteines within KEAP1 allows NRF2 to escape ubiquitination, accumulate within the cell, and translocate to the nucleus, where it can promote its antioxidant transcription program. Recent advances have revealed that KEAP1 contains multiple stress sensors and inactivation modalities, which together allow diverse cellular inputs, from oxidative stress and cellular metabolites to dysregulated autophagy, to regulate NRF2 activity. This integration of the KEAP1-NRF2 system into multiple cellular signaling and metabolic pathways places NRF2 activation as a critical regulatory node in many disease phenotypes and suggests that the pharmaceutical modulation of NRF2's cytoprotective activity will be beneficial for human health in a broad range of noncommunicable diseases.

    BACKGROUND: Genome-wide association studies provided many biological insights into coronary artery disease (CAD), but these studies were mainly performed in Europeans. Genome-wide association studies in diverse populations have the potential to advance our understanding of CAD. METHODS: We conducted 2 genome-wide association studies for CAD in the Japanese population, which included 12 494 cases and 28 879 controls and 2808 cases and 7261 controls, respectively. Then, we performed transethnic meta-analysis using the results of the coronary artery disease genome-wide replication and meta-analysis plus the coronary artery disease 1000 Genomes meta-analysis with UK Biobank. We then explored the pathophysiological significance of these novel loci and examined the differences in CAD-susceptibility loci between Japanese and Europeans. RESULTS: We identified 3 new loci on chromosome 1q21 (CTSS), 10q26 (WDR11-FGFR2), and 11q22 (RDX-FDX1). Quantitative trait locus analyses suggested the association of CTSS and RDX-FDX1 with atherosclerotic immune cells. Tissue/cell type enrichment analysis showed the involvement of arteries, adrenal glands, and fat tissues in the development of CAD. We next compared the odds ratios of lead variants for myocardial infarction at 76 genome-wide significant loci in the transethnic meta-analysis and a moderate correlation between Japanese and Europeans, where 8 loci showed a difference. Finally, we performed tissue/cell type enrichment analysis using East Asian-frequent and European-frequent variants according to the risk allele frequencies and identified significant enrichment of adrenal glands in the East Asian-frequent group while the enrichment of arteries and fat tissues was found in the European-frequent group. These findings indicate biological differences in CAD susceptibility between Japanese and Europeans. CONCLUSIONS: We identified 3 new loci for CAD and highlighted the genetic differences between the Japanese and European populations. Moreover, our transethnic analyses showed both shared and unique genetic architectures between the Japanese and Europeans. While most of the underlying genetic bases for CAD are shared, further analyses in diverse populations will be needed to elucidate variations fully.

    Chromosomal rearrangements between 3q21 and 3q26 elicit high-risk acute myeloid leukemia (AML), which is often associated with elevated platelet and megakaryocyte (Mk) numbers. The 3q rearrangements reposition a GATA2 enhancer near the EVI1 (or MECOM) locus, which results in both EVI1 overexpression and GATA2 haploinsufficiency. However, the mechanisms explaining how the misexpression of these 2 genes individually contribute to leukemogenesis are unknown. To clarify the characteristics of differentiation defects caused by EVI1 and GATA2 misexpression and to identify the cellular origin of leukemic cells, we generated a system to monitor both inv(3) allele-driven EVI1 and Gata2 expression in 3q-rearranged AML model mice. A cell population in which both EVI1 and Gata2 were highly induced appeared in the bone marrows before the onset of frank leukemia. This population had acquired serial colony-forming potential. Because hematopoietic stem/progenitor cells (HSPCs) and Mks were enriched in this peculiar population, we analyzed the independent EVI1 and GATA2 contributions to HSPC and Mk. We found that inv(3)-driven EVI1 promotes accumulation of Mk-biased and myeloid-biased progenitors, Mks, and platelets, and that Gata2 heterozygous deletion enhanced Mk-lineage skewing of EVI1-expressing progenitors. Notably, inv(3)-directed EVI1 expression and Gata2 haploinsufficient expression cooperatively provoke a leukemia characterized by abundant Mks and platelets. These hematological features of the mouse model phenocopy those observed in human 3q AML. On the basis of these results, we conclude that inv(3)-driven EVI1 expression in HSPCs and Mks collaborates with Gata2 haploinsufficiency to provoke Mk-lineage skewing and leukemogenesis with excessive platelets, thus mimicking an important feature of human AML.

    Understanding the root causes of neuronal vulnerability to ischemia is paramount to the development of new therapies for stroke. Transient global cerebral ischemia (tGCI) leads to selective neuronal cell death in the CA1 sub-region of the hippocampus, while the neighboring CA3 sub-region is left largely intact. By studying factors pertaining to such selective vulnerability, we can develop therapies to enhance outcome after stroke. Using untargeted liquid chromatography-mass spectrometry, we analyzed temporal metabolomic changes in CA1 and CA3 hippocampal areas following tGCI in rats till the setting of neuronal apoptosis. 64 compounds in CA1 and 74 in CA3 were found to be enriched and statistically significant following tGCI. Pathway analysis showed that pyrimidine and purine metabolism pathways amongst several others to be enriched after tGCI in CA1 and CA3. Metabolomics analysis was able to capture very early changes following ischemia. We detected 6 metabolites to be upregulated and 6 to be downregulated 1 hour after tGCI in CA1 versus CA3. Several metabolites related to apoptosis and inflammation were differentially expressed in both regions after tGCI. We offer a new insight into the process of neuronal apoptosis, guided by metabolomic profiling that was not performed to such an extent previously.

    Amino acids exert many biological functions, serving as allosteric regulators and neurotransmitters, as constituents in proteins and as nutrients. GCN2-mediated phosphorylation of eukaryotic initiation factor 2 alpha (elF2α) restores homeostasis in response to amino acid starvation (AAS) through the inhibition of the general translation and upregulation of amino acid biosynthetic enzymes and transporters by activating the translation of Gcn4 and ATF4 in yeast and mammals, respectively. GCN1 is a GCN2-binding protein that possesses an RWD binding domain (RWDBD) in its C-terminus. In yeast, Gcn1 is essential for Gcn2 activation by AAS; however, the roles of GCN1 in mammals need to be established. Here, we revealed a novel role of GCN1 that does not depend on AAS by generating two Gcn1 mutant mouse lines: Gcn1-knockout mice (Gcn1 KO mice (Gcn1-/-)) and RWDBD-deleted mutant mice (Gcn1ΔRWDBD mice). Both mutant mice showed growth retardation, which was not observed in the Gcn2 KO mice, such that the Gcn1 KO mice died at the intermediate stage of embryonic development because of severe growth retardation, while the Gcn1ΔRWDBD embryos showed mild growth retardation and died soon after birth, most likely due to respiratory failure. Extension of pregnancy by 24 h through the administration of progesterone to the pregnant mothers rescued the expression of differentiation markers in the lungs and prevented lethality of the Gcn1ΔRWDBD pups, indicating that perinatal lethality of the Gcn1ΔRWDBD embryos was due to simple growth retardation. Similar to the yeast Gcn2/Gcn1 system, AAS- or UV irradiation-induced elF2α phosphorylation was diminished in the Gcn1ΔRWDBD mouse embryonic fibroblasts (MEFs), suggesting that GCN1 RWDBD is responsible for GCN2 activity. In addition, we found reduced cell proliferation and G2/M arrest accompanying a decrease in Cdk1 and Cyclin B1 in the Gcn1ΔRWDBD MEFs. Our results demonstrated, for the first time, that GCN1 is essential for both GCN2-dependent stress response and GCN2-independent cell cycle regulation.

    The Tohoku Medical Megabank Project was designed as part of the national reconstruction project for addressing the damage from the 2011 Great East Japan Earthquake. It is an integrated project involving the genome cohort study of 150,000 participants, integrated biobank construction, and multi-omics analyses. Public relations and communication activities emerged to be extremely important in the successful development of this project. To gain insights into the contributions of these activities, we divided the public relations and communication activities for the project into three phases based on the situations surrounding the project. Prior to the start of the cohort study (Phase I), a cooperative relationship was established with a focus on concluding cooperation agreements with local governments. Until the participants reached the target number (Phase II), we actively communicated with the media to publicize the project. During the phase in which use of the constructed biobank is promoted (Phase III), for ensuring the industrial utilization of the biobank, visits from the industry are promoted. Throughout the execution of these activities, we explored the best strategies for building relationships with multiple stakeholders like local government, media and industry. By paying attention to these phases that have been changing according to the project's progress, we were able to adapt the strategies and methods of public relations and communication. The success of these activities has enabled the overall project to progress smoothly. We hope that the process of designing our project's public relations and communication activities will be useful for other similar initiatives.

    Cellular detoxication is essential for health because it provides protection against various chemicals and xenobiotics. The KEAP1-NRF2 system is important for cellular defense against oxidative and electrophilic stresses as NRF2 activates the transcription of an array of cytoprotective genes, including drug-metabolizing and antioxidant enzymes, in a stress-dependent manner. The CNC family of transcription factors, including NRF2, form heterodimers with small Maf (sMaf) proteins and bind to consensus DNA sequences that have been referred to as antioxidant response element, electrophile response element, or NF-E2-binding element. These sequences are now collectively called CNC-sMaf binding element (CsMBE). In addition to forming a heterodimer with CNC proteins, sMaf proteins can form homodimers and recognize regulatory motifs called Maf recognition element (MARE). Although the CsMBE sequence substantially overlaps with that of MARE, the sequences differ. NRF2 selectively recognizes CsMBE, which is critical for cytoprotection. Recent advances in high-throughput sequencing and population-scale genome analysis provide new insights into the transcriptional regulation involved in the stress response. The integration of a genome-wide map of NRF2 occupancy with disease-susceptibility loci reveals the associations between polymorphisms in CsMBE and disease risk, information useful for the personalized medicine of the future.

    The activation of the Kelch-like ECH-associated protein 1 (Keap1)-NF-E2-related factor 2 (Nrf2) pathway contributes to cancer progression in addition to oxidative stress responses. Loss-of-function Keap1 mutations were reported to activate Nrf2, leading to cancer progression. We examined the effects of Keap1 deletion in a cholangiocarcinoma mouse model using a mutant K-ras/p53 mouse. Introduction of the Keap1 deletion into liver-specific mutant K-ras/p53 expression resulted in the formation of invasive cholangiocarcinoma. Comprehensive analyses of the gene expression profiles identified broad upregulation of Nrf2-target genes such as Nqo1 and Gstm1 in the Keap1-deleted mutant K-ras/p53 expressing livers, accompanied by upregulation of cholangiocyte-related genes. Among these genes, the transcriptional factor Sox9 was highly expressed in the dysplastic bile duct. The Keap-Nrf2-Sox9 axis might serve as a novel therapeutic target for cholangiocarcinoma.NEW & NOTEWORTHY The Keap1-Nrf2 system has a wide variety of effects in addition to the oxidative stress response in cancer cells. Addition of the liver-specific Keap1 deletion to mice harboring mutant K-ras and p53 accelerated cholangiocarcinoma formation, together with the hallmarks of Nrf2 activation. This process involved the expansion of Sox9-positive cells, indicating increased differentiation toward the cholangiocyte phenotype.

    Nrf2 (NF-E2-related-factor 2) is a stress-responsive transcription factor that protects cells against oxidative stresses. To clarify whether Nrf2 prevents Alzheimer's disease (AD), AD model AppNL-G-F/NL-G-F knock-in (AppNLGF ) mice were studied in combination with genetic Nrf2 induction model Keap1FA/FA mice. While AppNLGF mice displayed shorter latency to escape than wild-type mice in the passive-avoidance task, the impairment was improved in AppNLGF ::Keap1FA/FA mice. Matrix-assisted laser desorption ionization-mass spectrometry imaging revealed that reduced glutathione levels were elevated by Nrf2 induction in AppNLGF ::Keap1FA/FA mouse brains compared to AppNLGF mouse brains. Genetic Nrf2 induction in AppNLGF mice markedly suppressed the elevation of the oxidative stress marker 8-OHdG and Iba1-positive microglial cell number. We also determined the plasmalogen-phosphatidylethanolamine (PlsPE) level as an AD biomarker. PlsPE containing polyunsaturated fatty acids was decreased in the AppNLGF mouse brain, but Nrf2 induction attenuated this decline. To evaluate whether pharmacological induction of Nrf2 elicits beneficial effects for AD treatment, we tested the natural compound 6-MSITC [6-(methylsulfinyl)hexyl isothiocyanate]. Administration of 6-MSITC improved the impaired cognition of AppNLGF mice in the passive-avoidance task. These results demonstrate that the induction of Nrf2 ameliorates cognitive impairment in the AD model mouse by suppressing oxidative stress and neuroinflammation, suggesting that Nrf2 is an important therapeutic target of AD.

    Aberrant activation of NRF2 is as a critical prognostic factor that drives the malignant progression of various cancers. Cancer cells with persistent NRF2 activation heavily rely on NRF2 activity for therapeutic resistance and aggressive tumorigenic capacity. To clarify the metabolic features of NRF2-activated lung cancers, we conducted targeted metabolomic (T-Met) and global metabolomic (G-Met) analyses of non-small-cell lung cancer (NSCLC) cell lines in combination with exome and transcriptome analyses. Exome analysis of 88 cell lines (49 adenocarcinoma, 14 large cell carcinoma, 15 squamous cell carcinoma and 10 others) identified non-synonymous mutations in the KEAP1, NRF2 and CUL3 genes. Judging from the elevated expression of NRF2 target genes, these mutations are expected to result in the constitutive stabilization of NRF2. Out of the 88 cell lines, 52 NSCLC cell lines (29 adenocarcinoma, 10 large cell carcinoma, 9 squamous cell carcinoma and 4 others) were subjected to T-Met analysis. Classification of the 52 cell lines into three groups according to the NRF2 target gene expression enabled us to draw typical metabolomic signatures induced by NRF2 activation. From the 52 cell lines, 18 NSCLC cell lines (14 adenocarcinoma, 2 large cell carcinoma, 1 squamous cell carcinoma and 1 others) were further chosen for G-Met and detailed transcriptome analyses. G-Met analysis of their culture supernatants revealed novel metabolites associated with NRF2 activity, which may be potential diagnostic biomarkers of NRF2 activation. This study also provides useful information for the exploration of new metabolic nodes for selective toxicity towards NRF2-activated NSCLC.

    Aryl hydrocarbon receptor (AhR) provides a deeper insight into the pathogenesis of cutaneous squamous cell carcinoma (cSCC). AhR ligands, such as 6-formylindolo[3,2-b] carbazole (FICZ), and 7,12-Dimethylbenz[a]anthracene (DMBA), constitute major substrates for the cytochrome P450 (CYP) family, and influence the expression of various cytokine genes, including IL-17 and IL-23-related genes via the AhR. On the other hand, proinflammatory cytokines could drive tumor progression through the TRAF-ERK5 signaling pathway in cSCC. From the above findings, we hypothesized that AhR ligands might enhance the mRNA expression of proinflammatory cytokines via the AhR, leading to the development of cSCC. The purpose of this study was to investigate (1) the immunomodulatory effects of FICZ and DMBA on normal human keratinocytes (NHKCs), focusing on IL-17, and related cytokines/chemokines (IL-23, IL-36γ, and CCL20), (2) the expression of these factors in AhR-dependent pathways using a two-stage chemically induced skin carcinogenesis mouse model, and (3) the expression of these factors in lesion-affected skin in cSCC. Both FICZ and DMBA augmented the expression of CYP1A1, p19, CCL20, and IL-36γ mRNA in NHKCs in vitro. Moreover, the mRNA expression of these proinflammatory factors, as well as IL-17, in mouse cSCC is significantly decreased in the AhR-(fl/fl) Krt5-(Cre) mice compared to wild type mice, leading to a decrease in the number of developed cSCC lesions. Furthermore, CCL20, IL-23, as well as IL-17, are detected in the lesion-affected skin of cSCC patients. Our study demonstrates a possible mechanism for the development of cSCC involving AhR-mediated signaling by epidermal keratinocytes and recruitment of Th17 cells.

    A baseline oral microbiome study of the Tohoku Medical Megabank Organization (TMM) was planned to characterize the profile of the oral microbiome in the Japanese population. The study also aimed to clarify risk factors for multifactorial diseases by integrated analysis of the oral microbiome and host genome/omics information. From 2013 to 2016, we collected three types of oral biospecimens, saliva, supragingival plaque, and tongue swab, from a total of 25,101 participants who had a dental examination in TMM. In this study, we used two independent cohorts; the Community-Based Cohort and Birth and Three-Generation Cohort as discovery and validation cohorts, respectively, and we selected participants examined by a single dentist. We found through the 16S ribosomal RNA gene sequencing analysis of 834 participants of the Community-Based Cohort Study that there are differences in the microbial composition and community structure between saliva and plaque. The species diversities in both saliva and plaque were increased in correlation with the severity of periodontal disease. These results were nicely reproduced in the analysis of 455 participants of the Birth and Three-Generation Cohort Study. In addition, strong positive and negative associations of microbial taxa in both plaque and saliva with periodontitis-associated biofilm formation were detected by co-occurrence network analysis. The classes Actinobacteria and Bacilli, including oral health-associated bacterial species, showed a positive correlation in saliva. These results revealed differences in microbial composition and community structure between saliva and plaque and a correlation between microbial species and the severity of periodontal disease. We expect that the large database of the oral microbiome in the TMM biobank will help in the discovery of novel targets for the treatment and prevention of oral diseases, as well as for the discovery of therapeutic and/or preventive targets of systemic diseases.

    PURPOSE: Pulse wave velocity (PWV), an indicator of vascular stiffness, increases with age and is increasingly recognized as an independent risk factor for cardiovascular disease (CVD). Although many mechanical and chemical factors underlie the stiffness of the elastic artery, genetic risk factors related to age-dependent increases in PWV in apparently healthy people are largely unknown. The transcription factor nuclear factor E2 (NF-E2)-related factor 2 (Nrf2), which is activated by unidirectional vascular pulsatile shear stress or oxidative stress, regulates vascular redox homeostasis. Previous reports have shown that a SNP in the NRF2 gene regulatory region (-617C>A; hereafter called SNP-617) affects NRF2 gene expression such that the minor A allele confers lower gene expression compared to the C allele, and it is associated with various diseases, including CVD. We aimed to investigate whether SNP-617 affects vascular stiffness with aging in apparently healthy people. METHODS: Analyzing wide-ranging data obtained from a public health survey performed in Japan, we evaluated whether SNP-617 affected brachial-ankle PWV (baPWV) in never-smoking healthy subjects (n = 642). We also evaluated the effects of SNP-617 on other cardiovascular and blood test measurements. RESULTS: We have shown that not only AA carriers (n = 55) but also CA carriers (n = 247) show arterial stiffness compared to CC carriers (n = 340). Furthermore, SNP-617 also affected blood pressure indexes such as systolic blood pressure and mean arterial pressure but not the ankle brachial pressure index, an indicator of atherosclerosis. Multivariate analysis showed that SNP-617 accelerates the incremental ratio of baPWV with age. CONCLUSIONS: This study is the first to show that SNP-617 affects the age-dependent increase in vascular stiffness. Our results indicate that low NRF2 activity induces premature vascular aging and could be targeted for the prevention of cardiovascular diseases associated with aging.

    The autophagy-endolysosomal pathway is an evolutionally conserved degradation system that is tightly linked to a wide variety of physiological processes. Dysfunction of this system is associated with many pathological conditions such as cancer, inflammation and neurodegenerative diseases. Therefore, monitoring the cellular autophagy-endolysosomal activity is crucial for studies on the pathogenesis as well as therapeutics of such disorders. To this end, we here sought to create a novel means exploiting Keima, an acid-stable fluorescent protein possessing pH-dependent fluorescence excitation spectra, for precisely monitoring the autophagy-endolysosomal system. First, we generated three lines of transgenic (tg) mouse expressing monomeric Keima-fused MAP1LC3B (mKeima-LC3B). Then, these tg mice were subjected to starvation by food-restriction, and also challenged to neurodegeneration by genetically crossing with a mouse model of amyotrophic lateral sclerosis; i.e., SOD1H46R transgenic mouse. Unexpectedly, despite that a lipidated-form of endogenous LC3 (LC3-II) was significantly increased, those of mKeima-LC3B (mKeima-LC3B-II) were not changed under both stressed conditions. It was also noted that mKeima-LC3B-positive aggregates were progressively accumulated in the spinal cord of SOD1H46R;mKeima-LC3B double-tg mice, suggestive of acid-resistance and aggregate-prone natures of long-term overexpressed mKeima-LC3B in vivo. Next, we characterized mouse embryonic fibroblasts (MEFs) derived from mKeima-LC3B-tg mice. In contrast with in vivo, levels of mKeima-LC3B-I were decreased under starved conditions. Furthermore, when starved MEFs were treated with chloroquine (CQ), the abundance of mKeima-LC3B-II was significantly increased. Remarkably, when cultured medium was repeatedly changed between DMEM (nutrient-rich) and EBSS (starvation), acidic/neutral signal ratios of mKeima-LC3B-positive compartments were rapidly and reversibly shifted, which were suppressed by the CQ treatment, indicating that intraluminal pH of mKeima-LC3B-positive vesicles was changeable upon nutritional conditions of culture media. Taken together, although mKeima-LC3B-tg mice may not be an appropriate tool to monitor the autophagy-endolysosomal system in vivo, mKeima-LC3B must be one of the most sensitive reporter molecules for monitoring this system under in vitro cultured conditions.

    Chromosomal inversion and translocation between 3q21 and 3q26 [inv (3)(q21.3q26.2) and t(3;3)(q21.3;q26.2), respectively] give rise to acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), which have poor prognoses. The chromosomal rearrangements reposition a GATA2 distal hematopoietic enhancer from the original 3q21 locus to the EVI1 (also known as MECOM) locus on 3q26. Therefore, the GATA2 enhancer from one of two GATA2 alleles drives EVI1 gene expression in hematopoietic stem and progenitor cells, which promotes the accumulation of abnormal progenitors and induces leukemogenesis. On the other hand, one allele of the GATA2 gene loses its enhancer, which results in reduced GATA2 expression. The GATA2 gene encodes a transcription factor critical for the generation and maintenance of hematopoietic stem and progenitor cells. GATA2 haploinsufficiency has been known to cause immunodeficiency and myeloid leukemia. Notably, reduced GATA2 expression suppresses the differentiation but promotes the proliferation of EVI1-expressing leukemic cells, which accelerates EVI1-driven leukemogenesis. A series of studies have shown that the GATA2 enhancer repositioning caused by the chromosomal rearrangements between 3q21 and 3q26 provokes misexpression of both the EVI1 and GATA2 genes and that these two effects coordinately elicit high-risk leukemia.

    BACKGROUND: Zinc oxide nanoparticles (ZnO-NPs) are widely used in many industrial sectors and previous studies have reported that exposure of the lungs to ZnO-NPs induces both acute and/or chronic pulmonary inflammation, but the exact mechanism underlying such response remains elusive. This study investigated the role of nuclear factor-erythroid 2-related factor (Nrf2) in pulmonary inflammation induced by exposure to ZnO-NPs using Nrf2 null (Nrf2-/-) mice. METHODS: Twenty-four male Nrf2-/- mice and thirty male wild type C57BL/6 J mice were divided into three groups of eight and ten each respectively, and exposed once to ZnO-NPs at 0, 10, 30 μg/mouse by pharyngeal aspiration. At 14 days after the exposure to ZnO-NPs, bronchoalveolar lavage fluid (BALF) and lungs were collected to quantify protein level and the number of inflammatory cells. The mRNA levels of Nrf2-dependent antioxidant enzymes and inflammatory cytokines in lung tissue were measured. RESULTS: Exposure to ZnO-NPs dose-dependently increased the number of total cells, macrophages, lymphocytes and eosinophils in BALF both in Nrf2-/- mice and wild type mice, but the magnitude of increase was significantly higher in Nrf2-/- mice than wild type mice. The number of neutrophils in BALF increased in Nrf2-/- mice, being accompanied by marginal trend of increase in mRNA expression of MIP-2, neutrophil chemoattractant, but such changes were not observed in wild type mice. Exposure to ZnO-NPs did not dose-dependently increase mRNA level of Nrf2-dependent antioxidant enzymes both in Nrf2-/- mice and wild type mice. CONCLUSION: Pharyngeal aspiration of ZnO-NPs induced infiltration of inflammatory cells in the lung of mice, but minimally induced Nrf2-dependent antioxidant enzymes. The results suggest that Nrf2 play a role in negative regulation on ZnO-NP exposure-induced neutrophil migration, but does not demonstrate that the regulation is through suppression of oxidative stress.

    Histamine is a biogenic amine that is chiefly produced in mast cells and basophils and elicits an allergic response upon stimulation. Histidine decarboxylase (HDC) is a unique enzyme that catalyzes the synthesis of histamine. Therefore, the spatiotemporally specific Hdc gene expression profile could represent the localization of histamine-producing cells under various pathophysiological conditions. Although the bioactivity of histamine is well defined, the regulatory mechanism of Hdc gene expression and the distribution of histamine-producing cell populations in various disease contexts remains unexplored. To address these issues, we generated a histidine decarboxylase BAC (bacterial artificial chromosome) DNA-directed GFP reporter transgenic mouse employing a 293-kb BAC clone containing the entire Hdc gene locus and extended flanking sequences (Hdc-GFP). We found that the GFP expression pattern in the Hdc-GFP mice faithfully recapitulated that of conventional histamine-producing cells and that the GFP expression level mirrored the increased Hdc expression in lipopolysaccharide (LPS)-induced septic lungs. Notably, a CD11b+Ly6G+Ly6Clow myeloid cell population accumulated in the lung during sepsis, and most of these cells expressed high levels of GFP and indeed contain histamine. This study reveals the accumulation of a histamine-producing myeloid cell population during sepsis, which likely participates in the immune process of sepsis.

    Transgenic mice expressing a constitutively active form of the aryl hydrocarbon receptor in keratinocytes (AhR-CA mice) develop severe dermatitis that substantially recapitulates the pathology of human atopic dermatitis. The neurotrophic factor artemin (Artn) is highly expressed in the epidermis of AhR-CA mice and causes hypersensitivity to itch (alloknesis) by elongating nerves into the epidermis. However, whether the Artn gene is regulated directly by AhR or indirectly through complex regulation associated with AhR remains unclear. To this end, we previously conducted chromatin immunoprecipitation-sequencing analyses of the Artn locus and found a xenobiotic response element (XRE) motif located far upstream (52 kb) of the gene. Therefore, in this study, we addressed whether the XRE actually regulates the Artn gene expression by deleting the region containing the motif. We generated two lines of ArtnΔXRE mice. In the mouse epidermis, inducible expression of the Artn gene by the AhR agonist 3-methylcholanthrene was substantially suppressed compared to that in wild-type mice. Importantly, in AhR-CA::ArtnΔXRE mice, Artn expression was significantly suppressed, and alloknesis was improved. These results demonstrate that the Artn gene is indeed regulated by the distal XRE-containing enhancer, and alloknesis in AhR-CA mice is provoked by the AhR-mediated direct induction of the Artn gene.

    Fanconi anemia is a rare recessive disease characterized by multiple congenital abnormalities, progressive bone marrow failure, and a predisposition to malignancies. It results from mutations in one of the 22 known FANC genes. The number of Japanese Fanconi anemia patients with a defined genetic diagnosis was relatively limited. In this study, we reveal the genetic subtyping and the characteristics of mutated FANC genes in Japan and clarify the genotype-phenotype correlations. We studied 117 Japanese patients and successfully subtyped 97% of the cases. FANCA and FANCG pathogenic variants accounted for the disease in 58% and 25% of Fanconi anemia patients, respectively. We identified one FANCA and two FANCG hot spot mutations, which are found at low percentages (0.04-0.1%) in the whole-genome reference panel of 3,554 Japanese individuals (Tohoku Medical Megabank). FANCB was the third most common complementation group and only one FANCC case was identified in our series. Based on the data from the Tohoku Medical Megabank, we estimate that approximately 2.6% of Japanese are carriers of disease-causing FANC gene variants, excluding missense mutations. This is the largest series of subtyped Japanese Fanconi anemia patients to date and the results will be useful for future clinical management.

    BACKGROUND: Genome cohort studies are used to analyze interactions between genetic and environmental factors, providing valuable information for personalized healthcare. Large-scale and long-term cohort studies require a number of specially trained personnel, of whom those involved in obtaining informed consent play a vital role, especially during the initial phase of such studies. The Japanese Society of Human Genetics (JSHG) previously established a certification system for genome medical research coordinators (GMRCs) responsible for obtaining written consent via face-to-face explanation. Meanwhile, in the Tohoku Medical Megabank Organization (ToMMo), GMRCs are expected to play important roles not only in obtaining informed consent and conducting various assessments, but also in communicating with participants throughout the long-term follow-up. Based on the JSHG program, we therefore developed a specific education and training program for ToMMo GMRCs consisting of 17 lectures, one practical training session on the informed consent procedure, and written and interview examinations. Re-education workshops aimed at self-improvement are also carried out following certification. In this study, we evaluated the education and training program in terms of overall understanding, usefulness, and satisfaction using an anonymous questionnaire. METHODS: An anonymous questionnaire addressing each aspect of the education and training program (understanding, usefulness, and satisfaction) was distributed among 152 qualified ToMMo GMRCs. Responses were received from 94 participants (61.8%). RESULTS: There was a significant association between the level of overall understanding of lectures and medical qualification (nurse or clinical laboratory technologist), but not with age or educational background. The level of understanding and overall usefulness were lower in sessions related to genetics and epidemiology than those dealing with ToMMo practices. In the re-education workshops, GMRCs showed a preference for and hoped to learn more about both background knowledge and research progress in the ToMMo. CONCLUSIONS: The results of our questionnaire suggest that not all ToMMo GMRCs are able to understand everything during the initial education and training program, especially in terms of genomic medicine. Continuous re-education is therefore vital in improving knowledge, skills and motivation, and preparing GMRCs for a specialist role in community-based personalized healthcare.

    The erythroid growth factor erythropoietin (Epo) is produced by renal interstitial fibroblasts, called REP (renal Epo-producing) cells, in a hypoxia-inducible manner. In chronic kidney disease (CKD), REP cells lose their Epo-production ability, leading to renal anaemia. Concurrently, REP cells are suggested to be transformed into myofibroblasts, which are the major player of renal fibrosis. Although establishment of cultured cell lines derived from REP cells has been a long-term challenge, we here successfully established a REP-cell-derived immortalized and cultivable cell line (Replic cells) by using a genetically modified mouse line. Replic cells exhibited myofibroblastic phenotypes and lost their Epo-production ability, reflecting the situation in renal fibrosis. Additionally, we found that cell-autonomous TGFβ signalling contributes to maintenance of the myofibroblastic features of Replic cells. Furthermore, the promoters of genes for Epo and HIF2α, a major activator of Epo gene expression, were highly methylated in Replic cells. Thus, these results strongly support our contention that REP cells are the origin of myofibroblasts in fibrotic kidneys and demonstrate that cell-autonomous TGFβ signalling and epigenetic silencing are involved in renal fibrosis and renal anaemia, respectively, in CKD. The Replic cell line is a useful tool to further investigate the molecular mechanisms underlying renal fibrosis.

    Zinc-finger transcription factors GATA2 and GATA3 are both expressed in the developing inner ear, although their overlapping versus distinct activities in adult definitive inner ear are not well understood. We show here that GATA2 and GATA3 are co-expressed in cochlear spiral ganglion cells and redundantly function in the maintenance of spiral ganglion cells and auditory neural circuitry. Notably, Gata2 and Gata3 compound heterozygous mutant mice had a diminished number of spiral ganglion cells due to enhanced apoptosis, which resulted in progressive hearing loss. The decrease in spiral ganglion cellularity was associated with lowered expression of neurotrophin receptor TrkC that is an essential factor for spiral ganglion cell survival. We further show that Gata2 null mutants that additionally bear a Gata2 YAC (yeast artificial chromosome) that counteracts the lethal hematopoietic deficiency due to complete Gata2 loss nonetheless failed to complement the deficiency in neonatal spiral ganglion neurons. Furthermore, cochlea-specific Gata2 deletion mice also had fewer spiral ganglion cells and resultant hearing impairment. These results show that GATA2 and GATA3 redundantly function t

    RATIONALE: Pulmonary arterial hypertension (PAH) is characterized by enhanced proliferation of pulmonary artery smooth muscle cells (PASMCs) accompanying increased production of inflammatory factors and adaptation of the mitochondrial metabolism to a hyperproliferative state. However, all the drugs in clinical use target pulmonary vascular dilatation, which may not be effective for patients with advanced PAH. OBJECTIVE: We aimed to discover a novel drug for PAH that inhibits PASMC proliferation. METHODS AND RESULTS: We screened 5562 compounds from original library using high-throughput screening system to discover compounds which inhibit proliferation of PASMCs from patients with PAH (PAH-PASMCs). We found that celastramycin, a benzoyl pyrrole-type compound originally found in a bacteria extract, inhibited the proliferation of PAH-PASMCs in a dose-dependent manner with relatively small effects on PASMCs from healthy donors. Then, we made 25 analogs of celastramycin and selected the lead compound, which significantly inhibited cell proliferation of PAH-PASMCs and reduced cytosolic reactive oxygen species levels. Mechanistic analysis demonstrated that celastramycin reduced the protein levels of HIF-1α (hypoxia-inducible factor 1α), which impairs aerobic metabolism, and κB (nuclear factor-κB), which induces proinflammatory signals, in PAH-PASMCs, leading to reduced secretion of inflammatory cytokine. Importantly, celastramycin treatment reduced reactive oxygen species levels in PAH-PASMCs with increased protein levels of Nrf2 (nuclear factor erythroid 2-related factor 2), a master regulator of cellular response against oxidative stress. Furthermore, celastramycin treatment improved mitochondrial energy metabolism with recovered mitochondrial network formation in PAH-PASMCs. Moreover, these celastramycin-mediated effects were regulated by ZFC3H1 (zinc finger C3H1 domain-containing protein), a binding partner of celastramycin. Finally, celastramycin treatment ameliorated pulmonary hypertension in 3 experimental animal models, accompanied by reduced inflammatory changes in the lungs. CONCLUSIONS: These results indicate that celastramycin ameliorates pulmonary hypertension, reducing excessive proliferation of PAH-PASMCs with less inflammation and reactive oxygen species levels, and recovered mitochondrial energy metabolism. Thus, celastramycin is a novel drug for PAH that targets antiproliferative effects on PAH-PASMCs.

    The Keap1-Nrf2 system plays a central role in the oxidative stress response; however, the identity of the reactive oxygen species sensor within Keap1 remains poorly understood. Here, we show that a Keap1 mutant lacking 11 cysteine residues retains the ability to target Nrf2 for degradation, but it is unable to respond to cysteine-reactive Nrf2 inducers. Of the 11 mutated cysteine residues, we find that 4 (Cys226/613/622/624) are important for sensing hydrogen peroxide. Our analyses of multiple mutant mice lines, complemented by MEFs expressing a series of Keap1 mutants, reveal that Keap1 uses the cysteine residues redundantly to set up an elaborate fail-safe mechanism in which specific combinations of these four cysteine residues can form a disulfide bond to sense hydrogen peroxide. This sensing mechanism is distinct from that used for electrophilic Nrf2 inducers, demonstrating that Keap1 is equipped with multiple cysteine-based sensors to detect various endogenous and exogenous stresses.

    Usual sleep duration has substantial heritability and is associated with various physical and psychiatric conditions as well as mortality. However, for its genetic locus, only PAX8 and VRK2 have been replicated in previous genome-wide association studies (GWAS). We conducted a GWAS meta-analysis of self-reported usual sleep duration using three population-based cohorts totaling 31 230 Japanese individuals. A genome-wide significant locus was identified at 12q24 (p-value < 5.0 × 10-8). Subsequently, a functional variant in the ALDH2 locus, rs671, was replicated in an independent sample of 5140 Japanese individuals (p-value = 0.004). The association signal, however, disappeared after adjusting for alcohol consumption, indicating the possibility that the rs671 genotype modifies sleep duration via alcohol consumption. This hypothesis explained a modest genetic correlation observed between sleep duration and alcohol consumption (rG = 0.23). A Mendelian randomization analysis using rs671 and other variants as instrumental variables confirmed this by showing a causal effect of alcohol consumption, but not of coffee consumption on sleep duration. Another genome-wide significant locus was identified at 5q33 after adjusting for drinking frequency. However, this locus was not replicated, nor was the PAX8 and VRK2. Our study has confirmed that a functional ALDH2 variant, rs671, most strongly influences on usual sleep duration possibly via alcohol consumption in the Japanese population, and presumably in East Asian populations. This highlights the importance of considering the involvement of alcohol consumption in future GWAS of usual sleep duration, even in non-East Asian populations, where rs671 is monomorphic.

    PURPOSE: Galactosemia is caused by metabolic disturbances at various stages of galactose metabolism, including deficiencies in enzymes involved in the Leloir pathway (GALT, GALK1, and GALE). Nevertheless, the etiology of galactosemia has not been identified in a subset of patients. This study aimed to explore the causes of unexplained galactosemia. METHODS: Trio-based exome sequencing and/or Sanger sequencing was performed in eight patients with unexplained congenital galactosemia. In vitro enzymatic assays and immunoblot assays were performed to confirm the pathogenicity of the variants. RESULTS: The highest blood galactose levels observed in each patient were 17.3-41.9 mg/dl. Bilateral cataracts were observed in two patients. In all eight patients, we identified biallelic variants (p.Arg82*, p.Ile99Leufs*46, p.Gly142Arg, p.Arg267Gly, and p.Trp311*) in the GALM encoding galactose mutarotase, which catalyzes epimerization between β- and α-D-galactose in the first step of the Leloir pathway. GALM enzyme activities were undetectable in lymphoblastoid cell lines established from two patients. Immunoblot analysis showed the absence of the GALM protein in the patients' peripheral blood mononuclear cells. In vitro GALM expression and protein stability assays revealed altered stabilities of the variant GALM proteins. CONCLUSION: Biallelic GALM pathogenic variants cause galactosemia, suggesting the existence of type IV galactosemia.

    Diabetic kidney disease is a major cause of renal failure that urgently necessitates a breakthrough in disease management. Here we show using untargeted metabolomics that levels of phenyl sulfate, a gut microbiota-derived metabolite, increase with the progression of diabetes in rats overexpressing human uremic toxin transporter SLCO4C1 in the kidney, and are decreased in rats with limited proteinuria. In experimental models of diabetes, phenyl sulfate administration induces albuminuria and podocyte damage. In a diabetic patient cohort, phenyl sulfate levels significantly correlate with basal and predicted 2-year progression of albuminuria in patients with microalbuminuria. Inhibition of tyrosine phenol-lyase, a bacterial enzyme responsible for the synthesis of phenol from dietary tyrosine before it is metabolized into phenyl sulfate in the liver, reduces albuminuria in diabetic mice. Together, our results suggest that phenyl sulfate contributes to albuminuria and could be used as a disease marker and future therapeutic target in diabetic kidney disease.

    BACKGROUND: Extramammary Paget disease (EMPD) is a rare cutaneous malignant neoplasm, and the genomic alterations underlying its pathogenesis are unknown. OBJECTIVE: To identify tumor-specific genomic alterations in EMPD. METHODS: Exome analysis was performed in specimens from three EMPD patients, and target amplicon sequencing was done for genes frequently mutated in other adenocarcinomas. RESULTS: Exome analysis revealed recurrent somatic mutations in several genes, includingTP53, PIK3CA, and ERBB2. We identified additional candidate exons by searching the COSMIC database for exons that are frequently mutated in other adenocarcinomas. We obtained 19 exons in 12 genes as candidate exons, and performed target amplicon sequencing in samples obtained from EMPD patients. New somatic mutations in the TP53 gene were identified in six EMPD patients. Single nucleotide polymorphism analysis revealed multiple chromosomal alterations in three EMPD specimens, and two specimens exhibited amplification of chromosome 12p13 and losses of 3p21-24, 7q22 and 13q12-21. CONCLUSION: Our comprehensive genetic analysis identified novel genomic alterations, and will inform treatment options for EMPD.

    PURPOSE: A prospective cohort study for pregnant women, the Maternity Log study, was designed to construct a time-course high-resolution reference catalogue of bioinformatic data in pregnancy and explore the associations between genomic and environmental factors and the onset of pregnancy complications, such as hypertensive disorders of pregnancy, gestational diabetes mellitus and preterm labour, using continuous lifestyle monitoring combined with multiomics data on the genome, transcriptome, proteome, metabolome and microbiome. PARTICIPANTS: Pregnant women were recruited at the timing of first routine antenatal visits at Tohoku University Hospital, Sendai, Japan, between September 2015 and November 2016. Of the eligible women who were invited, 65.4% agreed to participate, and a total of 302 women were enrolled. The inclusion criteria were age ≥20 years and the ability to access the internet using a smartphone in the Japanese language. FINDINGS TO DATE: Study participants uploaded daily general health information including quality of sleep, condition of bowel movements and the presence of nausea, pain and uterine contractions. Participants also collected physiological data, such as body weight, blood pressure, heart rate and body temperature, using multiple home healthcare devices. The mean upload rate for each lifelog item was ranging from 67.4% (fetal movement) to 85.3% (physical activity), and the total number of data points was over 6 million. Biospecimens, including maternal plasma, serum, urine, saliva, dental plaque and cord blood, were collected for multiomics analysis. FUTURE PLANS: Lifelog and multiomics data will be used to construct a time-course high-resolution reference catalogue of pregnancy. The reference catalogue will allow us to discover relationships among multidimensional phenotypes and novel risk markers in pregnancy for the future personalised early prediction of pregnancy complications.

    Personalized healthcare (PHC) based on an individual's genetic make-up is one of the most advanced, yet feasible, forms of medical care. The Tohoku Medical Megabank (TMM) Project aims to combine population genomics, medical genetics and prospective cohort studies to develop a critical infrastructure for the establishment of PHC. To date, a TMM CommCohort (adult general population) and a TMM BirThree Cohort (birth+three-generation families) have conducted recruitments and baseline surveys. Genome analyses as part of the TMM Project will aid in the development of a high-fidelity whole-genome Japanese reference panel, in designing custom single-nucleotide polymorphism (SNP) arrays specific to Japanese, and in estimation of the biological significance of genetic variations through linked investigations of the cohorts. Whole-genome sequencing from >3,500 unrelated Japanese and establishment of a Japanese reference genome sequence from long-read data have been done. We next aim to obtain genotype data for all TMM cohort participants (>150,000) using our custom SNP arrays. These data will help identify disease-associated genomic signatures in the Japanese population, while genomic data from TMM BirThree Cohort participants will be used to improve the reference genome panel. Follow-up of the cohort participants will allow us to test the genetic markers and, consequently, contribute to the realization of PHC.

    【背景と目的】環境中親電子物質は、タンパク質の求核基に共有結合することで親電子ストレスを惹起する。これら親電子ストレスに対する生体防御として、転写因子NF-E2-related factor 2 (Nrf2)が重要な役割を担っている。一方、我々は活性イオウ分子(Reactive Sulfur Species, RSS)が環境中親電子物質と反応することで、イオウ付加体を形成し、不活性化する新たな仕組みを見出した。さらに、生体内RSS産生酵素であるcystathionine gamma-lyase (CSE)が欠損するとイオウ付加体は殆ど生成されないことから、イオウ付加体形成にCSEが重要な役割を演じていることも報告した。つまり、親電子ストレスに対する生体防御にはNrf2のみならず、CSEが鍵分子であることを示唆している。本研究ではCSE/Nrf2両欠損マウスを作製し、親電子ストレスにおけるNrf2とCSEの役割を評価した。 【結果と考察】CSE/Nrf2の両欠損はそれぞれの単独欠損に比べ、親電子ストレスに対する脆弱性が高くなることが明らかとなった。このことは、従来のGSHによる抱合反応を介した解毒・排出機構とは別に、RSSによるイオウ付加体形成を介した不活性化機構が親電子物質毒性の抑制に重要であることを示している。興味深いことに、Nrf2の発現量およびGSH量は胎児期から成人期にかけて有意な変化は認められなかったのに対し、CSEの発現量およびRSS量は成人期と比べ胎児期で有意に低かった。本研究成果は、胎児期でのCSEの低発現とそれに起因するRSS量の低さが、胎児がメチル水銀のような胎盤通過性の高い親電子物質に対する虚弱性との関連性を示唆している。

    In recent genome analyses, population-specific reference panels have indicated important. However, reference panels based on short-read sequencing data do not sufficiently cover long insertions. Therefore, the nature of long insertions has not been well documented. Here, we assembled a Japanese genome using single-molecule real-time sequencing data and characterized insertions found in the assembled genome. We identified 3691 insertions ranging from 100 bps to ~10,000 bps in the assembled genome relative to the international reference sequence (GRCh38). To validate and characterize these insertions, we mapped short-reads from 1070 Japanese individuals and 728 individuals from eight other populations to insertions integrated into GRCh38. With this result, we constructed JRGv1 (Japanese Reference Genome version 1) by integrating the 903 verified insertions, totaling 1,086,173 bases, shared by at least two Japanese individuals into GRCh38. We also constructed decoyJRGv1 by concatenating 3559 verified insertions, totaling 2,536,870 bases, shared by at least two Japanese individuals or by six other assemblies. This assembly improved the alignment ratio by 0.4% on average. These results demonstrate the importance of refining the reference assembly and creating a population-specific reference genome. JRGv1 and decoyJRGv1 are available at the JRG website.

    The first step towards realizing personalized healthcare is to catalog the genetic variations in a population. Since the dissemination of individual-level genomic information is strictly controlled, it will be useful to construct population-level allele frequency panels with easy-to-use interfaces. In the Tohoku Medical Megabank Project, we sequenced nearly 4000 individuals from a Japanese population and constructed an allele frequency panel of 3552 individuals after removing related samples. The panel is called the 3.5KJPNv2. It was constructed by using a standard pipeline including the 1KGP and gnomAD algorithms to reduce technical biases and to allow comparisons to other populations. Our database is the first large-scale panel providing the frequencies of variants present on the X chromosome and on the mitochondria in the Japanese population. All the data are available on our original database at https://jmorp.megabank.tohoku.ac.jp.

    Blood pressure (BP) is a major risk factor for cardiovascular disease and more than 200 genetic loci associated with BP are known. Here, we perform a multi-stage genome-wide association study for BP (max N = 289,038) principally in East Asians and meta-analysis in East Asians and Europeans. We report 19 new genetic loci and ancestry-specific BP variants, conforming to a common ancestry-specific variant association model. At 10 unique loci, distinct non-rare ancestry-specific variants colocalize within the same linkage disequilibrium block despite the significantly discordant effects for the proxy shared variants between the ethnic groups. The genome-wide transethnic correlation of causal-variant effect-sizes is 0.898 and 0.851 for systolic and diastolic BP, respectively. Some of the ancestry-specific association signals are also influenced by a selective sweep. Our results provide new evidence for the role of common ancestry-specific variants and natural selection in ethnic differences in complex traits such as BP.

    BACKGROUND: The association between eczema and mental health problems in schoolchildren has been underexplored. We aimed to investigate this association with the validated questionnaires. METHODS: Of 46,648 invited children, we analyzed 9954 (21.3%) in the 2nd to the 8th grades from the ToMMo Child Health Study conducted in 2014 and 2015, a cross-sectional survey in Miyagi Prefecture, Japan. We defined eczema status as "normal," "mild/moderate," or "severe," based on the presence of persistent flexural eczema and sleep disturbance, according to the International Study of Asthma and Allergies in Childhood (ISAAC) Eczema Symptom Questionnaire. Clinical ranges of Strengths and Difficulties Questionnaire (SDQ) total difficulties scores and four SDQ subcategories of emotional symptoms, conduct problems, hyperactivity/inattention, and peer problems were defined as scores ≥16, ≥5, ≥5, ≥7, and ≥5, respectively. RESULTS: The mean SDQ total difficulties score significantly increased as eczema status worsened (all P ≤ 0.004 for trend). The OR of scores in the clinical range for SDQ total difficulties were 1.51 (95% CI, 1.31-1.74) for mild/moderate eczema and 2.63 (95% CI, 1.91-3.63) for severe eczema (P < 0.001 for trend), adjusted for sex, school grade, current wheeze, and disaster-related factors, using normal eczema as a reference. The association between severity of eczema and four SDQ subcategories showed a similar trend (all P ≤ 0.017 for trend). CONCLUSIONS: We found a significant association between severity of eczema and mental health problems. The presence of eczema was associated with four SDQ subcategories.

    Cancer cells often heavily depend on the ubiquitin-proteasome system (UPS) for their growth and survival. Irrespective of their strong dependence on the proteasome activity, cancer cells, except for multiple myeloma, are mostly resistant to proteasome inhibitors. A major cause of this resistance is the proteasome bounce-back response mediated by NRF1, a transcription factor that coordinately activates proteasome subunit genes. To identify new targets for efficient suppression of UPS, we explored, using immunoprecipitation and mass spectrometry, the possible existence of nuclear proteins that cooperate with NRF1 and identified O-linked N-acetylglucosamine transferase (OGT) and host cell factor C1 (HCF-1) as two proteins capable of forming a complex with NRF1. O-GlcNAcylation catalyzed by OGT was essential for NRF1 stabilization and consequent upregulation of proteasome subunit genes. Meta-analysis of breast and colorectal cancers revealed positive correlations in the relative protein abundance of OGT and proteasome subunits. OGT inhibition was effective at sensitizing cancer cells to a proteasome inhibitor both in culture cells and a xenograft mouse model. Since active O-GlcNAcylation is a feature of cancer metabolism, our study has clarified a novel linkage between cancer metabolism and UPS function and added a new regulatory axis to the regulation of the proteasome activity.

    In glaucoma, although axonal injury drives retinal ganglion cell (RGC) death, little is known about the underlying pathomechanisms. To provide new mechanistic insights and identify new biomarkers, we combined latest non-targeting metabolomics analyses to profile altered metabolites in the mouse whole retina 2, 4, and 7 days after optic nerve crush (NC). Ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry and liquid chromatography Fourier transform mass spectrometry covering wide spectrum of metabolites in combination highlighted 30 metabolites that changed its concentration after NC. The analysis displayed similar changes for purine nucleotide and glutathione as reported previously in another animal model of axonal injury and detected multiple metabolites that increased after the injury. After studying the specificity of the identified metabolites to RGCs in histological sections using imaging mass spectrometry, two metabolites, i.e., L-acetylcarnitine and phosphatidylcholine were increased not only preceding the peak of RGC death in the whole retina but also at the RGC layer (2.3-fold and 1.2-fold, respectively). These phospholipids propose novel mechanisms of RGC death and may serve as early biomarkers of axonal injury. The combinatory metabolomics analyses promise to illuminate pathomechanisms, reveal biomarkers, and allow the discovery of new therapeutic targets of glaucoma.

    BACKGROUND: Genotype imputation from single-nucleotide polymorphism (SNP) genotype data using a haplotype reference panel consisting of thousands of unrelated individuals from populations of interest can help to identify strongly associated variants in genome-wide association studies. The Tohoku Medical Megabank (TMM) project was established to support the development of precision medicine, together with the whole-genome sequencing of 1070 human genomes from individuals in the Miyagi region (Northeast Japan) and the construction of the 1070 Japanese genome reference panel (1KJPN). Here, we investigated the performance of 1KJPN for genotype imputation of Japanese samples not included in the TMM project and compared it with other population reference panels. RESULTS: We found that the 1KJPN population was more similar to other Japanese populations, Nagahama (south-central Japan) and Aki (Shikoku Island), than to East Asian populations in the 1000 Genomes Project other than JPT, suggesting that the large-scale collection (more than 1000) of Japanese genomes from the Miyagi region covered many of the genetic variations of Japanese in mainland Japan. Moreover, 1KJPN outperformed the phase 3 reference panel of the 1000 Genomes Project (1KGPp3) for Japanese samples, and IKJPN showed similar imputation rates for the TMM and other Japanese samples for SNPs with minor allele frequencies (MAFs) higher than 1%. CONCLUSIONS: 1KJPN covered most of the variants found in the samples from areas of the Japanese mainland outside the Miyagi region, implying 1KJPN is representative of the Japanese population's genomes. 1KJPN and successive reference panels are useful genome reference panels for the mainland Japanese population. Importantly, the addition of whole genome sequences not included in the 1KJPN panel improved imputation efficiencies for SNPs with MAFs under 1% for samples from most regions of the Japanese archipelago.

    Macrophages manifest distinct phenotype according to the organs in which they reside. In addition, they flexibly switch their character in adaptation to the changing environment. However, the molecular basis that explains the conversion of the macrophage phenotype has so far been unexplored. We find that CD169+ macrophages change their phenotype by regulating the level of a transcription factor Maf both in vitro and in vivo in C57BL/6J mice. When CD169+ macrophages were exposed to bacterial components, they expressed an array of acute inflammatory response genes in Maf-dependent manner and simultaneously start to downregulate Maf. This Maf suppression is dependent on accelerated degradation through proteasome pathway and microRNA-mediated silencing. The downregulation of Maf unlocks the NF-E2-related factor 2-dominant, cytoprotective/antioxidative program in the same macrophages. The present study provides new insights into the previously unanswered question of how macrophages initiate proinflammatory responses while retaining their capacity to repair injured tissues during inflammation.

    Population-based prospective cohort studies are indispensable for modern medical research as they provide important knowledge on the influences of many kinds of genetic and environmental factors on the cause of disease. Although traditional cohort studies are mainly conducted using questionnaires and physical examinations, modern cohort studies incorporate omics and genomic approaches to obtain comprehensive physical information, including genetic information. Here, we report the design and midterm results of multi-omics analysis on population-based prospective cohort studies from the Tohoku Medical Megabank (TMM) Project. We have incorporated genomic and metabolomic studies in the TMM cohort study as both metabolome and genome analyses are suitable for high-throughput analysis of large-scale cohort samples. Moreover, an association study between the metabolome and genome show that metabolites are an important intermediate phenotype connecting genetic and lifestyle factors to physical and pathologic phenotypes. We apply our metabolome and genome analyses to large-scale cohort samples in the following studies.

    Nrf2 plays critical roles in animals' defense against electrophiles and oxidative stress by orchestrating the induction of cytoprotective genes. We previously isolated the zebrafish mutant it768, which displays up-regulated expression of Nrf2 target genes in an uninduced state. In this paper, we determine that the gene responsible for it768 was the zebrafish homolog of phosphomannomutase 2 (Pmm2), which is a key enzyme in the initial steps of N-glycosylation, and its mutation in humans leads to PMM2-CDG (congenital disorders of glycosylation), the most frequent type of CDG. The pmm2 it768 larvae exhibited mild defects in N-glycosylation, indicating that the pmm2 it768 mutation is a hypomorph, as in human PMM2-CDG patients. A gene expression analysis showed that pmm2 it768 larvae display up-regulation of endoplasmic reticulum (ER) stress, suggesting that the activation of Nrf2 was induced by the ER stress. Indeed, the treatment with the ER stress-inducing compounds up-regulated the gstp1 expression in an Nrf2-dependent manner. Furthermore, the up-regulation of gstp1 by the pmm2 inactivation was diminished by knocking down or out double-stranded RNA-activated protein kinase (PKR)-like ER kinase (PERK), one of the main ER stress sensors, suggesting that Nrf2 was activated in response to the ER stress via the PERK pathway. ER stress-induced activation of Nrf2 was reported previously, but the results have been controversial. Our present study clearly demonstrated that ER stress can indeed activate Nrf2 and this regulation is evolutionarily conserved among vertebrates. Moreover, ER stress induced in pmm2 it768 mutants was ameliorated by the treatment of the Nrf2-activator sulforaphane, indicating that Nrf2 plays significant roles in the reduction of ER stress.

    Clarifying allele frequencies of disease-related genetic variants in a population is important in genomic medicine; however, such data is not yet available for the Japanese population. To estimate frequencies of actionable pathogenic variants in the Japanese population, we examined the reported pathological variants in genes recommended by the American College of Medical Genetics and Genomics (ACMG) in our reference panel of genomic variations, 2KJPN, which was created by whole-genome sequencing of 2049 individuals of the resident cohort of the Tohoku Medical Megabank Project. We searched for pathogenic variants in 2KJPN for 57 autosomal ACMG-recommended genes responsible for 26 diseases and then examined their frequencies. By referring to public databases of pathogenic variations, we identified 143 reported pathogenic variants in 2KJPN for the 57 ACMG recommended genes based on a classification system. At the individual level, 21% of the individuals were found to have at least one reported pathogenic allele. We then conducted a literature survey to review the variants and to check for evidence of pathogenicity. Our results suggest that a substantial number of people have reported pathogenic alleles for the ACMG genes, and reviewing variants is indispensable for constructing the information infrastructure of genomic medicine for the Japanese population.

    We developed jMorp, a new database containing metabolome and proteome data for plasma obtained from >5000 healthy Japanese volunteers from the Tohoku Medical Megabank Cohort Study, which is available at https://jmorp.megabank.tohoku.ac.jp. Metabolome data were measured by proton nuclear magnetic resonance (NMR) and liquid chromatography-mass spectrometry (LC-MS), while proteome data were obtained by nanoLC-MS. We released the concentration distributions of 37 metabolites identified by NMR, distributions of peak intensities of 257 characterized metabolites by LC-MS, and observed frequencies of 256 abundant proteins. Additionally, correlation networks for the metabolites can be observed using an interactive network viewer. Compared with some existing databases, jMorp has some unique features: (i) Metabolome data were obtained using a single protocol in a single institute, ensuring that measurement biases were significantly minimized; (ii) The database contains large-scale data for healthy volunteers with various health records and genome data and (iii) Correlations between metabolites can be easily observed using the graphical viewer. Metabolites data are becoming important intermediate markers for evaluating the health states of humans, and thus jMorp is an outstanding resource for a wide range of researchers, particularly those in the fields of medical science, applied molecular biology, and biochemistry.

    In the FANTOM5 project, transcription initiation events across the human and mouse genomes were mapped at a single base-pair resolution and their frequencies were monitored by CAGE (Cap Analysis of Gene Expression) coupled with single-molecule sequencing. Approximately three thousands of samples, consisting of a variety of primary cells, tissues, cell lines, and time series samples during cell activation and development, were subjected to a uniform pipeline of CAGE data production. The analysis pipeline started by measuring RNA extracts to assess their quality, and continued to CAGE library production by using a robotic or a manual workflow, single molecule sequencing, and computational processing to generate frequencies of transcription initiation. Resulting data represents the consequence of transcriptional regulation in each analyzed state of mammalian cells. Non-overlapping peaks over the CAGE profiles, approximately 200,000 and 150,000 peaks for the human and mouse genomes, were identified and annotated to provide precise location of known promoters as well as novel ones, and to quantify their activities.

    Lung cancer accompanied by somatic activating mutations in the epidermal growth factor receptor (EGFR) gene, which is associated with a significant clinical response to the targeted therapy, is frequently found in never-smoking Asian women with adenocarcinoma. Although this implies genetic factors underlying the carcinogenesis, the etiology remains unclear. To gain insight into the pathogenic mechanisms, we sequenced the exomes in the peripheral-blood DNA from six siblings, four affected and two unaffected siblings, of a family with familial EGFR-mutant lung adenocarcinoma. We identified a heterozygous missense mutation in MET proto-oncogene, p.Asn375Lys, in all four affected siblings. Combined with somatic loss of heterozygosity for MET, the higher allele frequency in a Japanese sequencing database supports a causative role of the MET mutation in EGFR-mutant lung cancer. Functional assays showed that the mutation reduces the binding affinity of MET for its ligand, hepatocyte growth factor, and damages the subsequent cellular processes, including proliferation, clonogenicity, motility and tumorigenicity. The MET mutation was further observed to abrogate the ERBB3-mediated AKT signal transduction, which is shared downstream by EGFR. These findings provide an etiological view that the MET mutation is involved in the pathogenesis of EGFR-mutant lung cancer because it generates oncogenic stress that induces compensatory EGFR activation. The identification of MET in a family with familial EGFR-mutant lung cancer is insightful to explore the pathogenic mechanism of not only familial, but also sporadic EGFR-mutant lung cancer by underscoring MET-related signaling molecules.

    Placental activation of the renin-angiotensin system (RAS) plays a key role in the pathogenesis of preeclampsia. Reactive oxygen species (ROS) are thought to affect placental angiogenesis, which is critical for preventing preeclampsia pathology. We examined the role of ROS in preeclampsia by genetically modifying the Keap1-Nrf2 pathway, a cellular antioxidant defense system, in a mouse model of RAS-induced preeclampsia. Nrf2 deficiency would be expected to impair cellular antioxidant responses; however, Nrf2 deficiency in preeclamptic mice improved maternal and fetal survival, ameliorated intra-uterine growth retardation, and augmented oxidative DNA damage. Furthermore, the placentas of Nrf2-deficient mice had increased endothelial cell proliferation with dense vascular networks. In contrast, the placentas of preeclamptic mice with overactive Nrf2 showed repressed angiogenesis, which was associated with decreased expression of genes encoding angiogenic chemokines and cytokines. Our findings support the notion that ROS-mediated signaling is essential for maintaining placental angiogenesis in preeclampsia and may provide mechanistic insight into the negative results of clinical trials for antioxidants in preeclampsia.

    The erythropoietin (Epo) gene is under tissue-specific inducible regulation. Because the kidney is the primary EPO-producing tissue in adults, impaired EPO production in chronic kidney disorders results in serious renal anemia. The Epo gene contains a liver-specific enhancer in the 3' region, but the kidney-specific enhancer for gene expression in renal EPO-producing (REP) cells remains elusive. Here, we examined a conserved upstream element for renal Epo regulation (CURE) region that spans 17.4 kb to 3.6 kb upstream of the Epo gene and harbors several phylogenetically conserved elements. We prepared various Epo gene-reporter constructs utilizing a bacterial artificial chromosome and generated a number of transgenic-mouse lines. We observed that deletion of the CURE region (δCURE) abrogated Epo gene expression in REP cells. Although transgenic expression of the δCURE construct rescued Epo-deficient mice from embryonic lethality, the rescued mice had severe EPO-dependent anemia. These mouse lines serve as an elaborate model for the search for erythroid stimulatory activity and are referred to as AnRED (anemic model with renal EPO deficiency) mice. We also dissected the CURE region by exploiting a minigene harboring four phylogenetically conserved elements in reporter transgenic-mouse analyses. Our analyses revealed that Epo gene regulation in REP cells is a complex process that utilizes multiple regulatory influences.

    Nrf2 (NF-E2-related factor-2) transcription factor regulates oxidative/xenobiotic stress response and also represses inflammation. However, the mechanisms how Nrf2 alleviates inflammation are still unclear. Here, we demonstrate that Nrf2 interferes with lipopolysaccharide-induced transcriptional upregulation of proinflammatory cytokines, including IL-6 and IL-1β. Chromatin immunoprecipitation (ChIP)-seq and ChIP-qPCR analyses revealed that Nrf2 binds to the proximity of these genes in macrophages and inhibits RNA Pol II recruitment. Further, we found that Nrf2-mediated inhibition is independent of the Nrf2-binding motif and reactive oxygen species level. Murine inflammatory models further demonstrated that Nrf2 interferes with IL6 induction and inflammatory phenotypes in vivo. Thus, contrary to the widely accepted view that Nrf2 suppresses inflammation through redox control, we demonstrate here that Nrf2 opposes transcriptional upregulation of proinflammatory cytokine genes. This study identifies Nrf2 as the upstream regulator of cytokine production and establishes a molecular basis for an Nrf2-mediated anti-inflammation approach.

    The KEAP1-NRF2 system plays a central role in cytoprotection. NRF2 is stabilized in response to electrophiles and activates transcription of antioxidant genes. Although robust induction of NRF2 target genes confers resistance to oxidative insults, how NRF2 triggers transcriptional activation after binding to DNA has not been elucidated. To decipher the molecular mechanisms underlying NRF2-dependent transcriptional activation, we purified the NRF2 nuclear protein complex and identified the Mediator subunits as NRF2 cofactors. Among them, MED16 directly associated with NRF2. Disruption of Med16 significantly attenuated the electrophile-induced expression of NRF2 target genes but did not affect hypoxia-induced gene expression, suggesting a specific requirement for MED16 in NRF2-dependent transcription. Importantly, we found that 75% of NRF2-activated genes exhibited blunted inductions by electrophiles in Med16-deficient cells compared to wild-type cells, which strongly argues that MED16 is a major contributor supporting NRF2-dependent transcriptional activation. NRF2-dependent phosphorylation of the RNA polymerase II C-terminal domain was absent in Med16-deficient cells, suggesting that MED16 serves as a conduit to transmit NRF2-activating signals to RNA polymerase II. MED16 indeed turned out to be essential for cytoprotection against oxidative insults. Thus, the KEAP1-NRF2-MED16 axis has emerged as a new regulatory pathway mediating the antioxidant response through the robust activation of NRF2 target genes.

    Erythropoietin (Epo) is produced by renal Epo-producing cells (REPs) in a hypoxia-inducible manner. The conversion of REPs into myofibroblasts and coincident loss of Epo-producing ability are the major cause of renal fibrosis and anemia. However, the hypoxic response of these transformed myofibroblasts remains unclear. Here, we used complementary in vivo transgenic and live imaging approaches to better understand the importance of hypoxia signaling in Epo production. Live imaging of REPs in transgenic mice expressing green fluorescent protein from a modified Epo-gene locus revealed that healthy REPs tightly associated with endothelium by wrapping processes around capillaries. However, this association was hampered in states of renal injury-induced inflammation previously shown to correlate with the transition to myofibroblast-transformed renal Epo-producing cells (MF-REPs). Furthermore, activation of hypoxia-inducible factors (HIFs) by genetic inactivation of HIF-prolyl hydroxylases (PHD1, PHD2, and PHD3) selectively in Epo-producing cells reactivated Epo production in MF-REPs. Loss of PHD2 in REPs restored Epo-gene expression in injured kidneys but caused polycythemia. Notably, combined deletions of PHD1 and PHD3 prevented loss of Epo expression without provoking polycythemia. Mice with PHD-deficient REPs also showed resistance to LPS-induced Epo repression in kidneys, suggesting that augmented HIF signaling counterbalances inflammatory stimuli in regulation of Epo production. Thus, augmentation of HIF signaling may be an attractive therapeutic strategy for treating renal anemia by reactivating Epo synthesis in MF-REPs.

    Nrf2は生体防御に働く遺伝子の発現を制御する転写因子である。DDC(3,5-diethoxycarbonyl-1, 4-dihydro-collidine)は、ヘム生合成経路を阻害して肝障害を引き起こす肝毒性物質である。我々はDDCによる肝障害に対してNrf2が防御に働くのではないかと考え、Nrf2活性化能が異なる遺伝子改変マウスに0.1%DDC混餌食を給餌した。すべての遺伝子型の体重はDDC投与後に減少したが、Nrf2が恒常的に活性化している肝臓特異的Keap1欠失(Keap1–/–)マウスは1週後から回復した。このような体重の回復は肝臓特異的Keap1:Nrf2二重欠失(Keap1–/–:Nrf2–/–)マウスでは観察されなかったので、Keap1–/–の体重回復はNrf2に依存することが示された。体重の回復に一致して、Keap1–/–マウスではDDCによる血中肝障害マーカーやビリルビンの上昇が著しく抑制された。DDCはヘム前駆体プロトポルフィリンIX(PPIX)を蓄積するが、Keap1–/–マウスでは野生型に比べて肝中ポルフィリンの蓄積が軽減した。PPIXの肝外排泄は、ABCトランスポーターであるABCG2が、ビリルビンの排泄はMRP2(胆管側)とMRP3(血管側)が担っている。Abcg2Abcc4などのトランスポーターはNrf2の標的遺伝子であり、特にMRP4はNrf2活性化能に依存した発現上昇が見られた。また、Keap1–/–マウスはDDCにより肝重量比が著しく増加し、DDC投与1週後に増殖マーカーであるKi67の発現の上昇もmRNAおよびタンパク質レベルで確認された。以上より、Keap1–/–マウスにおける恒常的なNrf2の活性化は、ポルフィリン排泄、ビリルビン代謝、そして細胞増殖を促進することによって、PPIXによる肝障害を著しく抑制することが示された。

    近年の科学技術の発展は、私たちの生活を豊かなものにした一方で、多くの化学物質を産出し、それらの生体に対する有害作用が時として社会問題をひき起こしていることも否めない。高齢化社会の進展に伴い、生活習慣病の罹患者数が急増しているが、加齢に伴う生体防御の衰えがこうした病態の基盤をなしていることも理解され始めている。すなわち、環境中の毒性化学物質や私たちの体に内在するストレスの処理能力の維持が、私たちの生存と健康保持に極めて重要である。これらのストレスへの応答のためにも、生体防御機能の深い理解が必須である。<br> 赤血球分化や機能発現制御過程の解明に取り組む過程で、転写因子NF-E2の分子実態がp45と小Maf(sMaf)因子の形成する2量体であることに気がついた。この発見は、CNC因子群とsMaf因子群の2量体からなる転写因子群が存在することを明らかにしたパラダイムシフトであった。ところで、毒性学の分野において、以前から化学物質(特に、親電子性毒物)による発がんが抗酸化剤の前投与により抑制できること(化学発がん予防)、また、本事象は第2相解毒酵素群の誘導発現を基盤としていることが知られていた。第2相解毒酵素の遺伝子群には、共通して抗酸化剤応答配列(ARE)と呼ばれる制御配列が存在していることから、AREにある種の転写因子が結合して遺伝子発現が誘導され、化学発がん予防が惹起されるものと予想されたが、実際にはその実態解明はたいへん難航した。<br> 私たちは、ARE結合転写因子は赤血球系NF-E2と同様のメカニズムを採用している可能性に気がつき、この仮説を検証した。この過程で、CNC群因子Nrf2を同定し、また、Nrf2遺伝子欠失マウスを作成・解析して、Nrf2とsMafの2量体が実際にAREに結合して第2相酵素群遺伝子を活性化する転写因子の本体であることを突き止めた。さらに、長い間謎であった親電子性毒物と酸化ストレスのセンサーであるKeap1を発見し、Keap1-Nrf2制御系が生体防御において中心的な役割を果たしていることを明らかにした。また、Keap1-Nrf2制御系の解析を進め、本系の機能障害がさまざまな疾患の分子基盤を形成していることを見出した。さらに、Nrf2活性制御が疾患の予防と治療に有効であることを実証した。この成果をうけて、現在、Nrf2活性化剤が多発性硬化症の治療薬として承認されており、糖尿病性腎症の治療薬も実用化にも近づきつつある。<br> Keap1-Nrf2制御系の分子メカニズム解明は、基礎生命科学において極めて重要な概念の確立をもたらした。平常時には、Nrf2はKeap1により迅速に分解されているが、細胞が酸化ストレスや親電子性毒物に曝露されると、Keap1が失活してNrf2分解が停止する。その結果、Nrf2は細胞内に蓄積し、様々な生体防御遺伝子群の発現を活性化する。これにより細胞はストレスに対する抵抗力を増大させる。すなわち、環境ストレス応答の実態はKeap1によるNrf2の恒常的分解による抑制からの「脱抑制」である。そして、Keap1の反応性システイン残基がこれらの環境ストレスを鋭敏に感知する。ストレスセンサーの分子基盤は「システインコード」(システイン残基修飾による遺伝子発現制御)である。<br> このように、本研究は環境ストレスに対する生体応答メカニズム研究領域におけるフロンティアを開拓しており、その成果は毒性学の発展に大きく貢献するものと確信している。

    Our body has ability to sense environmental insults and to activate cellular defense enzyme genes. Transcription factor Nrf2 is essential for the coordinated induction of cellular defense enzymes and protection of lung tissues through association with CNC-sMaf binding element (CsMBE or ARE/EpRE). This notion has been supported by experiments using animal models, showing that Nrf2-null mice are sensitive to a wide variety of toxic electrophiles and ROS. Keap1 acts as a subunit of ubiquitin-E3 ligase that degrades Nrf2 constitutively and as sensors for electrophilic and oxidative stresses, and covalent modifications of the cysteine residues abrogate the ubiquitin ligase activity. This system has been referred to as the Cysteine Code. The two-site recognition / hinge and latch model proposed for the Keap1-Nrf2 system describes the mechanism of nuclear accumulation of Nrf2 in a Cul3-Keap1 E3 ubiquitin ligase-dependent manner. We have verified this model through structure biology, mouse genetics, and human disease analyses. Many missense mutations have been identified in KEAP1 and NRF2 genes of human lung cancers. These mutations disrupt the KEAP1-NRF2 complex and result in constitutive activation of NRF2. Subsequently, elevated expression of NRF2 target genes confers advantages on the growth of cancer cells through the metabolic reprogramming. Thus, the Keap1-Nrf2 system opens a new avenue to the understanding of the signal transduction and regulatory processes underlying the stress response and cancer progression.

    Erythropoietin (Epo) is produced in the kidney and liver in a hypoxia-inducible manner via the activation of hypoxia-inducible transcription factors (HIFs) to maintain oxygen homeostasis. Accelerating Epo production in hepatocytes is one plausible therapeutic strategy for treating anemia caused by kidney diseases. To elucidate the regulatory mechanisms of hepatic Epo production, we analyzed mouse lines harboring liver-specific deletions of genes encoding HIF-prolyl-hydroxylase isoforms (PHD1, PHD2, and PHD3) that mediate the inactivation of HIF1α and HIF2α under normal oxygen conditions. The loss of all PHD isoforms results in both polycythemia, which is caused by Epo overproduction, and fatty livers. We found that deleting any combination of two PHD isoforms induces polycythemia without steatosis complications, whereas the deletion of a single isoform induces no apparent phenotype. Polycythemia is prevented by the loss of either HIF2α or the hepatocyte-specific Epo gene enhancer (EpoHE). Chromatin analyses show that the histones around EpoHE dissociate from the nucleosome structure after HIF2α activation. HIF2α also induces the expression of HIF3α, which is involved in the attenuation of Epo production. These results demonstrate that the total amount of PHD activity is more important than the specific function of each isoform for hepatic Epo expression regulated by a PHD-HIF2α-EpoHE cascade in vivo.

    Nrf2は毒物代謝や抗酸化に関わる酵素群の遺伝子発現を統一的に制御する転写因子である。Nrf2欠失マウスを用いた解析から、毒物代謝におけるNrf2の重要性が示されてきたが、一方、マウス特有の解毒代謝酵素の発現によりマウスが毒性評価に適さない場合もあった。その一例がアフラトキシンB1(AFB1)である。AFB1はピーナッツなどの食品に付着するカビ毒で、肝臓がんの原因物質である。マウスではAFB1の解毒代謝に関わるグルタチオンS-転移酵素A3(GSTA3)の発現が高く、AFB1毒性に対して耐性を示す。そこで、我々は新たな毒性評価モデル動物としてNrf2欠失ラットを作製し、AFB1毒性に対するNrf2の防御効果を調べた。Nrf2欠失ラットの肝臓では、Nrf2活性化剤CDDO-Im投与によってNrf2の核蓄積が起こらず、Nrf2下流遺伝子の発現応答も消失した。AFB1の解毒代謝に重要なGSTA3およびアルドケト還元酵素7A3(AKR7A3)は、Nrf2欠失ラット肝臓において、通常時およびCDDO-Im誘導時のいずれにおいても抑制されていた。AFB1を連続投与するとNrf2欠失ラットでは体重増加が抑制され、50%は死亡した。また、CDDO-Im投与によって、Nrf2欠失ラットにおけるAFB1による死亡は防御できなかった。遺伝子およびタンパク質の発現解析から、Nrf2はAFB1の解毒代謝に関わるGSTA3、GSTA5、AKR7A3の発現を誘導していた。そのため、Nrf2欠失ラットでは、AFB1の解毒代謝中間体によるDNA付加体が野生型ラットより多く形成され、遺伝子変異を起こしやすいことが予想される。毒性学では古くよりラットが用いられてきた背景があるので、今回我々が作製したNrf2欠失ラットは、AFB1のみならず多くの毒性評価に新しいツールとなることが期待される。

    The human POLH gene is responsible for the variant form of xeroderma pigmentosum (XP-V), a genetic disease highly susceptible to cancer on sun-exposed skin areas, and encodes DNA polymerase η (polη), which is specialized for translesion DNA synthesis (TLS) of UV-induced DNA photolesions. We constructed polη-deficient mice transgenic with lacZ mutational reporter genes to study the effect of Polh null mutation (Polh(-/-)) on mutagenesis in the skin after UVB irradiation. UVB induced lacZ mutations with remarkably higher frequency in the Polh(-/-) epidermis and dermis than in the wild-type (Polh(+/+)) and heterozygote. DNA sequences of a hundred lacZ mutants isolated from the epidermis of four UVB-exposed Polh(-/-) mice were determined and compared with mutant sequences from irradiated Polh(+)(/)(+) mice. The spectra of the mutations in the two genotypes were both highly UV-specific and dominated by C→T transitions at dipyrimidines, namely UV-signature mutations. However, sequence preferences of the occurrence of UV-signature mutations were quite different between the two genotypes: the mutations occurred at a higher frequency preferentially at the 5'-TCG-3' sequence context than at the other dipyrimidine contexts in the Polh(+/+) epidermis, whereas the mutations were induced remarkably and exclusively at the 3'-cytosine of almost all dipyrimidine contexts with no preference for 5'-TCG-3' in the Polh(-/-) epidermis. In addition, in Polh(-/-) mice, a small but remarkable fraction of G→T transversions was also observed exclusively at the 3'-cytosine of dipyrimidine sites, strongly suggesting that these transversions resulted not from oxidative damage but from UV photolesions. These results would reflect the characteristics of the error-prone TLS functioning in the bypass of UV photolesions in the absence of polη, which would be mediated by mechanisms based on the two-step model of TLS. On the other hand, the deamination model would explain well the mutation spectrum in the Polh(+/+) genotype.

    Using methodology developed herein, it is found that reactive persulfides and polysulfides are formed endogenously from both small molecule species and proteins in high amounts in mammalian cells and tissues. These reactive sulfur species were biosynthesized by two major sulfurtransferases: cystathionine β-synthase and cystathionine γ-lyase. Quantitation of these species indicates that high concentrations of glutathione persulfide (perhydropersulfide >100 μM) and other cysteine persulfide and polysulfide derivatives in peptides/proteins were endogenously produced and maintained in the plasma, cells, and tissues of mammals (rodent and human). It is expected that persulfides are especially nucleophilic and reducing. This view was found to be the case, because they quickly react with H2O2 and a recently described biologically generated electrophile 8-nitroguanosine 3',5'-cyclic monophosphate. These results indicate that persulfides are potentially important signaling/effector species, and because H2S can be generated from persulfide degradation, much of the reported biological activity associated with H2S may actually be that of persulfides. That is, H2S may act primarily as a marker for the biologically active of persulfide species.

    Regulated transcription controls the diversity, developmental pathways and spatial organization of the hundreds of cell types that make up a mammal. Using single-molecule cDNA sequencing, we mapped transcription start sites (TSSs) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of mammalian gene expression across the human body. We find that few genes are truly 'housekeeping', whereas many mammalian promoters are composite entities composed of several closely separated TSSs, with independent cell-type-specific expression profiles. TSSs specific to different cell types evolve at different rates, whereas promoters of broadly expressed genes are the most conserved. Promoter-based expression analysis reveals key transcription factors defining cell states and links them to binding-site motifs. The functions of identified novel transcripts can be predicted by coexpression and sample ontology enrichment analyses. The functional annotation of the mammalian genome 5 (FANTOM5) project provides comprehensive expression profiles and functional annotation of mammalian cell-type-specific transcriptomes with wide applications in biomedical research.

    The Keap1-Nrf2 system protects animals from oxidative and electrophilic stresses. Nrf2 is a transcription factor that induces the expression of genes essential for detoxifying reactive oxygen species (ROS) and cytotoxic electrophiles. Keap1 is a stress sensor protein that binds to and ubiquitinates Nrf2 under unstressed conditions, leading to the rapid proteasomal degradation of Nrf2. Upon exposure to stress, Keap1 is modified and inactivated, which allows Nrf2 to accumulate and activate the transcription of a battery of cytoprotective genes. Antioxidative and detoxification activities are important for many types of cells to avoid DNA damage and cell death. Accumulating lines of recent evidence suggest that Nrf2 is also required for the primary functions of myeloid cells, which include phagocytosis, inflammation regulation, and ROS generation for bactericidal activities. In fact, results from several mouse models have shown that Nrf2 expression in myeloid cells is required for the proper regulation of inflammation, antitumor immunity, and atherosclerosis. Moreover, several molecules generated upon inflammation activate Nrf2. Although ROS detoxification mediated by Nrf2 is assumed to be required for anti-inflammation, the entire picture of the Nrf2-mediated regulation of myeloid cell primary functions has yet to be elucidated. In this review, we describe the Nrf2 inducers characteristic of myeloid cells and the contributions of Nrf2 to diseases.

    Our bodies must counteract insults originating from the environment. Toxic chemicals (electrophiles) and reactive oxygen species (ROS) activate expression of detoxifying and antioxidant genes through antioxidant responsive element (ARE). Transcription factor Nrf2 is essential for the coordinated induction of cellular defense enzymes through ARE. This notion is best demonstrated in animal models, showing that Nrf2-null mice are sensitive to a wide variety of electrophiles and ROS. Keap1 is identified as a negative regulator of Nrf2. Electrophiles liberate Nrf2 from the repression by Keap1 and provoke nuclear accumulation of Nrf2. Keap1 possesses multiple reactive cysteine residues that covalently bound with electrophiles, indicating that Keap1 acts as a sensor for xenobiotic stresses and we refer this system to as the Cysteine Code. Mouse and zebrafish models demonstrate that multiple sensor functions reside within Keap1. The hinge and latch model proposed for the Keap1-Nrf2 system describes the regulation of nuclear accumulation of Nrf2 by a Cul3- Keap1 E3 ubiquitin ligase-dependent mechanism. We have verified this model through structure biology, mouse/zebrafish genetics and human cancer analyses. In human cancers, missense mutations have been identified in KEAP1 and NRF2 genes. These mutations disrupt the KEAP1-NRF2 complex and result in constitutive activation of NRF2. Elevated expression of NRF2 target genes confers advantages on cancer cells. Transgenic mouse models provide evidence that mutated form of Keap1 analogous to cancer genotypes lose the ability to repress Nrf2 in vivo. Thus, the Keap1-Nrf2 system opens a new avenue to the understanding of the signal transduction and regulatory processes underlying the stress response and cancer progression.

    The Keap1-Nrf2 system plays a central role in cytoprotection against oxidative and electrophilic insults. Under normal conditions Keap1 serves as a substrate adaptor for Cullin3-based ubiquitin E3 ligase and promotes proteasomal degradation of Nrf2. Keap1 is inactivated upon the exposure to environmental stimuli such as electrophiles, and in this situation Nrf2 is stabilized and activates transcription of cytoprotective genes. Nrf2 knockout mouse (Nrf2–/–) is very sensitive to toxicants like acetaminophen. On the other hand, Keap1 knockdown mouse (Keap1flox/flox) in which Nrf2 is activated is resistant to toxicants. Whereas the turnover of Nrf2 has been well analyzed, little is known about the Keap1 turnover or recovery of the Keap1 activity after the electrophilic insults. We found that Keap1 is accumulated when autophagy is impaired in the liver of mice. Treatment of cells with an autophagy inhibitor or inducer markedly increased or decreased the Keap1 level, respectively. The Keap1 degradation was accelerated upon the exposure to certain type of electrophiles, implying that inactivated Keap1 after modification with electrophiles becomes a preferred substrate of autophagy. We also found that the electrophilic challenge enhances the transcription of Keap1 gene, suggesting that the Keap1 activity is recovered by de novo synthesis of Keap1. Consequently, Keap1 protein was kept in constant level even in the presence of electrophiles. These results thus demonstrate that Keap1 is degraded through autophagy and that this degradation machinery in concert with the de novo synthesis of Keap1 maintains the active Keap1 level and the redox homeostasis regulated by Nrf2.

    OBJECTIVE: To investigate the potential role of nuclear factor-erythroid 2-related factor 2 (Nrf2) in neovascularization with a murine surgical model of ischemia. METHODS AND RESULTS: The transcription factor Nrf2 protects against oxidative stress by increasing the transcription of genes, including those for several antioxidant enzymes that contain an antioxidant response element. Ischemia was induced by femoral artery ligation in Nrf2-deficient (Nrf2(-/-)) and wild-type mice. Ischemia-induced neovascularization was enhanced in Nrf2(-/-) mice compared with that in wild-type mice. The expression of Nrf2 target genes for heme oxygenase 1 and thioredoxin 1 and the concentration of total glutathione in the ischemic hindlimb were reduced for Nrf2(-/-) mice compared with wild-type mice. The infiltration of inflammatory cells and the abundance of adhesion molecule mRNA were greater in the ischemic hindlimb of Nrf2(-/-) mice than in wild-type mice. The expression of monocyte chemoattractant protein-1, tumor necrosis factor-alpha, cyclooxygenase 2, and angiogenic factors in the ischemic hindlimb was also greater for Nrf2(-/-) mice than for wild-type mice. CONCLUSIONS: The ablation of Nrf2 promoted ischemia-induced neovascularization. This effect likely resulted from impaired antioxidant defense and increased accumulation of reactive oxygen species in endothelial cells; consequently, there was an enhanced inflammatory response.

    1-Bromopropane (1-BP) was introduced as an alternative to ozone-depleting solvents. However, it was found to exhibit neurotoxicity, reproductive toxicity, and hepatotoxicity in rodents and neurotoxicity in human. However, the mechanisms underlying the toxicities of 1-BP remain elusive. The present study investigated the role of oxidative stress in 1-BP-induced hepatotoxicity using nuclear factor erythroid 2-related factor 2 (Nrf2)-null mice. Groups of 24 male Nrf2-null mice and 24 male wild-type (WT) C57BL/6J mice were each divided into three groups of eight and exposed to 1-BP at 0, 100, or 300 ppm for 8 h/day for 28 days by inhalation. Liver histopathology showed significantly larger area of necrosis in Nrf2-null mice relative to WT mice at the same exposure level. Nrf2-null mice also had greater malondialdehyde (MDA) levels, higher ratio of oxidized glutathione/reduced form of glutathione, and lower total glutathione content. The constitutive level and the increase in ratio per exposure level of glutathione S-transferase (GST) activity were lower in the liver of Nrf2-null mice than WT mice. Exposure to 1-BP at 300 ppm increased the messenger RNA levels of heme oxygenase-1 (HO-1), glutamate-cysteine ligase modifier subunit (GcLm), glutamate-cysteine synthetase (GcLc), glutathione reductase, and NAD(P)H: quinone oxidoreductase 1 (NQO1) in WT mice but not in Nrf2-null mice except for GST Yc2. Nrf2-null mice were more susceptible to 1-BP-induced hepatotoxicity. That oxidative stress plays a role in 1-BP hepatotoxicity is deduced from the low expression levels and activities of antioxidant enzymes and high MDA levels in Nrf2-null mice.

    The transcription factor Nrf2 is a key regulator for hepatic induction of detoxifying enzymes, antioxidative stress genes and Mrp efflux transporters. We aimed to investigate whether Nrf2 activation counteracts liver injury associated with cholestasis. The role of Nrf2 activation in counteracting cholestatic liver injury was studied using a bile duct-ligation (BDL) model of Keap1 gene-knockdown (Keap1-kd) mice that represent the sustained activation of Nrf2 in the liver. Upon Nrf2 activation, Keap1-kd mice showed large increases in Mrp efflux transporters, detoxifying enzymes and antioxidative stress genes in the livers. After BDL, the number of hepatic parenchymal necrosis and the reactive oxygen species content were significantly smaller in the livers of the Keap1-kd mice than in those of the WT mice. Moreover, the increase in serum bilirubin levels was attenuated in the Keap1-kd mice. In conclusion, the results suggest a hepatoprotective role of sustained Nrf2 activation against liver injury associated with cholestasis.

    A straightforward mechanism for eliciting transcriptional repression would be to simply block the DNA binding site for activators. Such passive repression is often mediated by transcription factors that lack an intrinsic repressor activity. MafG is a bidirectional regulator of transcription, a repressor in its homodimeric state but an activator when heterodimerized with p45. Here, we report that MafG is conjugated to SUMO-2/3 in vivo. To clarify the possible physiological role(s) for sumoylation in regulating MafG activity, we evaluated mutant and wild-type MafG in transgenic mice and cultured cells. Whereas sumoylation-deficient MafG activated p45-dependent transcription normally and did not affect heterodimer activity, repression by the sumoylation-deficient MafG mutant was severely compromised in vivo. Furthermore, the SUMO-dependent repression activity of MafG was sensitive to histone deacetylase inhibition. Thus, repression by MafG is not achieved through simple passive repression by competing for the activator binding site but requires sumoylation, which then mediates transcriptional repression through recruitment of a repressor complex containing histone deacetylase activity.

    炭素質コンドライトに含まれる低分子量の可溶性有機物は、初期太陽系の環境を推定するための指標となる可能性がある。このような有機分子の研究は、ほとんどの場合が抽出液の分析によって行われてきた。本研究では表面支援レーザー脱離イオン化質量分析(SALDI)法により高空間分解能で炭素質コンドライト中の多種の有機物の空間分布を測定した。検出された多様なCHN化合物は同族体であり、類似した不均質な分布を示した。このことは、逐次反応が隕石構成微粒子ごとに起こっていること示しており、CHN化合物の生成が母天体集積前に起こったことを示唆している。

    Acrylamide (ACR) is an electrophile which has been used extensively in industry and is also formed unintentionally in food substances cooked or processed at high temperatures, such as potato chips or coffee through Maillard reaction. Acrylamide has been recognized as a potent neurotoxin which is known to cause neuropathy or encephalopathy in humans and experimental animals. As a measure of protection against neurotoxicity, the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) has been identified to be a master regulator of the cellular defense system which activates antioxidant and cytoprotective genes. However, knowledge about mechanistic roles of Nrf2 in acrylamide-induced neurotoxicity remains poorly understood. This study therefore sought to investigate and clarify the roles of Nrf2 in ACR-induced neurotoxicity. Forty-eight male Nrf2-knockout (Nrf2-KO) mice from the C57BL/6JJcl background, aged 10-weeks together with their age and sex-matched wild-type (WT) counterparts were each divided into four groups of twelve and daily exposed to ACR at 0, 67, 110 or 200 ppm in drinking water for 28 days. Following exposure of mice to ACR, Landing Foot spread test, an assessment of motor function and a major endpoint marker of neurotoxicity as well as immunohistochemistry for noradrenaline transporter (NAT) and serotonin transporter (SERT) antibody in the dorsal and ventral medial prefrontal cortex were performed. Nrf2-KO mice showed exacerbated impairment of motor functions evidenced by the increased hindlimb splay relative to WT mice at the same exposure levels. Immunohistochemistry results showed severe degeneration of both noradrenergic and serotonergic axons characterized by a dose-dependent decrease in the density of immunoreactive axons in Nrf2-KO mice relative to WT mice. Moreover, body weight, whole brain weight and cerebellum weight were significantly reduced in Nrf2-KO mice compared to the WT mice. The results suggest increased susceptibility to ACR-induced neurotoxicity in mice lacking the Nrf2 gene. In conclusion, Nrf2 is able to attenuate the effects of ACR-induced neurotoxicity in mice and thus remains a crucial target for the preventive modulation of neurotoxicity.

    Kidney has ability to adapt its size and function against partial nephron loss to maintain total renal function, for example, in both donor and recipient in renal transplantation. However, the factors that regulate this compensation have not been fully clarified yet. Hereby we examined the effects of erythropoietin (EPO)/anemia on the compensatory renal hypertrophy in the mice lacking EPO production. The anemic mice showed similar compensatory renal hypertrophy compared to normoxemic mice at week 1 after unilateral nephrectomy (UNX). However, the compensation was disrupted only in anemic mice at week 4 after UNX, which was accompanied by the decreased phosphorylation of ribosomal protein S6, a marker of mTOR activation. In the renal interstitium of anemic mice at week 4 of UNX, the number of cells promoting epo gene transcription (but disable to produce EPO protein in the mice) was reduced even under the anemia, and the number of α-smooth muscle actin-positive cells was increased, suggesting the transdifferentiation of EPO-producing cells into myofibroblast. These changes were restored by the supplementation of recombinant EPO. In conclusion, EPO is not essential for the onset of compensatory renal hypertrophy after UNX, but is essential to maintain the compensation persistently.

    The Keap1-Nrf2 system protects animals from oxidative and electrophilic stresses. Nrf2 is a transcription factor that induces the expression of genes essential for detoxifying reactive oxygen species (ROS) and cytotoxic electrophiles. Keap1 is a stress sensor protein that binds to and ubiquitinates Nrf2 under unstressed conditions, leading to the rapid proteasomal degradation of Nrf2. Upon exposure to stress, Keap1 is modified and inactivated, which allows Nrf2 to accumulate and activate the transcription of a battery of cytoprotective genes. Antioxidative and detoxification activities are important for many types of cells to avoid DNA damage and cell death. Accumulating lines of recent evidence suggest that Nrf2 is also required for the primary functions of myeloid cells, which include phagocytosis, inflammation regulation, and ROS generation for bactericidal activities. In fact, results from several mouse models have shown that Nrf2 expression in myeloid cells is required for the proper regulation of inflammation, antitumor immunity, and atherosclerosis. Moreover, several molecules generated upon inflammation activate Nrf2. Although ROS detoxification mediated by Nrf2 is assumed to be required for anti-inflammation, the entire picture of the Nrf2-mediated regulation of myeloid cell primary functions has yet to be elucidated. In this review, we describe the Nrf2 inducers characteristic of myeloid cells and the contributions of Nrf2 to diseases.

    【目的】ヘムオキシゲナーゼ-1(HO-1)はヘム分解の律速酵素であり、その酵素反応の代謝物の抗酸化作用から、酸化ストレスに対する防御作用を示すことが知られている。また、HO-1は様々な物質により誘導されることが報告されている。その中には天然化合物も含まれており、イソチオシアネート関連化合物やクルクミンなどもin vitroにおいてHO-1を誘導することが報告されている。しかし、これらの化合物のin vivoにおける作用は明らかではない。そこで本研究では、HO-1の転写因子として重要な役割を担っているNrf2のノックアウト(KO)マウスを用い、in vivoにおけるイソチオシアネート関連化合物によるHO-1誘導を検討した。【方法】C57BL/6系雄性の野生型(WT)及びNrf2 KOマウスにアリルイソチオシアネート(AITC)を腹腔内投与し、経時的に肝臓を摘出した。肝臓より常法に従いmRNAを抽出し、またミクロソーム画分を調製し、HO-1のmRNAとタンパク質をそれぞれノーザンブロット法とウエスタンブロット法を用いて測定した。【結果及び考察】WT及びNrf2 KOマウスにAITC(25mg/kg, i.p.)を処置し、HO-1タンパク量を検討したところ、両マウスにおいて有意な増加が認められた。その後用量依存性について検討した結果、WTマウスにおいては、HO-1のmRNA量及びタンパク量は用量依存的に増加した。以上のことから、AITCはin vivoにおいてもHO-1を誘導することが分かった。また、AITCは、Nrf2 KOマウスにおいてもHO-1誘導を引き起こすことから、in vitroの誘導機構とされているNrf2を介する以外の経路の関与が示唆された。現在、他の類縁化合物についても検討を進めているところである。

    【目的】転写因子Nrf2は抗酸化タンパク質群や薬物代謝第二相酵素群など生体防御関連遺伝子発現を統合的に制御し、酸化ストレス、発がん物質、環境汚染物質などから生体を保護する。シトクロムP450(P450)は、薬物代謝第一相反応において酸化反応を触媒する酵素群であり、薬物によるP450の誘導は、PXRやCAR等の分子種特異的な転写因子の存在が明らかとなっている。本研究では生体防御という一連の観点から、Nrf2がP450の遺伝子発現調節にも関与するという仮説を立て検討を行った。【方法】C57BL/6系雄性、8週齢のwild-type(WT)および Nrf2 ノックアウト(KO)マウスにブチルヒドロキシアニソール(BHA)、ホロン、フェノバルビタール(PB)を処置し、経時的に肝臓を摘出した。Cyp2b10のmRNAとタンパク質はそれぞれノーザンブロット法とウェスタンブロット法より測定した。肝におけるPBREM転写活性化はPBREM-Lucリポーターベクターを、CARの核移行はCAR-GFP発現ベクターをトランスフェクトすることにより検討した。【結果及び考察】BHA、ホロンおよびOPZ処置によるP450各分子種のmRNA量の変動を検討したところ、特にCyp2b10 mRNAで強い増加が認められた。さらに、Nrf2 KOマウスを用いてホロンによるCyp2b10の mRNA量、タンパク量の変動を検討したところWT比較して両者とも有意に低下していた。次にNrf2活性化物質によるCyp2b10誘導が、Nrf2による制御なのか、転写因子CARによるものなのかを詳細に検討する目的でPBを用いて検討した。WTマウスと比較してNrf2 KOマウスでは、PBのCyp2b10 mRNA誘導能が有意に減弱した。さらに、BHA処置12時間後にCARの核集積が確認され、BHA処置よるCARの核移行が明らかとなった。また、PBREM転写活性がホロン処置24時間後で上昇した。しかし、Nrf2 KOマウスではこれらのことが認められなかった。以上のことから、Nrf2のCyp2bの遺伝子発現への関与が示唆された。

    私たちは常に外界からのストレスに曝されており、それに対する応答は生体の恒常性維持に必須である。酸素、紫外線、大気や食物中の化学物質などが重要な環境由来ストレスとなっているが、これらのストレス因子の増加は生体内レドックスバランスの撹乱を招来し、多くの疾患の共通基盤を形成している。超高齢化社会での健康長寿を実現するためには、生体の酸化ストレス応答機構全容の理解とその制御メカニズムの詳細な解明が極めて重要である。本研究では、生体の酸化ストレス応答機構において中心的な役割を果たしているKEAP1-NRF2制御系の機能メカニズムの解明に挑むとともに、ストレス関連疾患の予防・治療に対する同制御系の貢献を明らかにする。特に、生体がKEAP1を利用して過剰な酸素によるストレスを感知するメカニズムとそのストレス感知が生体防御遺伝子群の発現の変化を惹起するメカニズムの解明に挑戦する。 当該年度は、国際宇宙ステーション長期滞在から帰還したマウスの詳細な解析を行った結果、NRF2が宇宙環境における代謝変化に重要な役割を果たしていることが明らかになった。特に、宇宙滞在がリン脂質やコレステロールの濃度を上昇させる一方で、中性脂肪濃度を低下させることが明らかとなった。また、各種組織の遺伝子発現量を調べたところ、それぞれの組織で脂質を調節する遺伝子の発現量が変化していることが明らかになった。本研究成果は、Commun Biol誌に報告した。 また、核磁気共鳴法によりKEAP1とNRF2の2つのモチーフの結合状態を同時に観測することに成功した。KEAP1-NRF2タンパク質間相互作用を阻害する低分子の添加によりNRF2のLatchに相当する結合モチーフがKEAP1から解離することが観測され、Hinge & Latchモデルの証明に成功した。本研究成果は、Commun Biol誌に報告した。

    Nrf2は環境ストレスに応答して活性化する。Nrf2は通常Keap1により抑制されているが、Keap1を欠失した場合にはストレスがない状態でもNrf2は常に活性化する。Keap1欠失マウスは、食道閉塞による母乳摂取不全のため生後間もなく死亡してしまい、詳細に調べることが困難であった。そこで、食道におけるNrf2の発現を欠失することで、成獣まで生育できるKeap1欠失マウスを作製し、食道以外の全身組織でのNrf2過剰活性化による影響を検討した。その結果、腎臓発生期のNrf2活性化は尿崩症を呈することを発見した。今後、腎性尿崩症の発症機序の理解およびその治療や予防に役立つと期待される。

    GATA1は赤血球・巨核球分化に重要な転写因子であり、アミノ末端とカルボキシル末端に二つの転写活性化領域(N-TAD、C-TAD)をもつ。N-TADの欠失が、ダウン症患児における急性巨核芽球性白血病にかかわっていることがわかっている。N-TADとC-TADをそれぞれ欠失したトランスジェニックマウス系統の解析から、N-TADおよびC-TADの両方が胎児肝造血に重要であるが、一方の転写活性化領域の機能欠失が他方の転写活性化領域の機能増強により代償できること、この代償機構は赤血球系と巨核球系で異なっており、TMDの発症には転写活性化領域欠失による転写不均衡が一因となっている可能性を見いだした。

    転写因子であるNrf2は酸化ストレスなどにより活性化され、数多くの抗酸化酵素を増加させることで、ストレス防御に重要な役割を果たしている。Keap1はストレスセンサーを感知してNrf2の機能を制御しており、Keap1-Nrf2システムとして生体の環境維持に重要な役割を果たしている。本研究では、Keap1-Nrf2システムの膵β細胞における役割について解析を行った。膵ランゲルハンス島において、Nrf2標的遺伝子群は、酸化ストレス等によって誘導され、Nrf2遺伝子ノックアウトマウスの膵ランゲルハンス島ではNrf2標的遺伝子の発現は低下していた。さらに、膵β細胞障害モデルマウスにおけるNrf2遺伝子ヘテロノックアウトは、膵ランゲルハンス島の障害を悪化させ、血糖値を上昇させた。以上より、Keap1-Nrf2システムは膵β細胞におけるストレスに対する防御機構に重要な役割を果たしており、その破綻は糖尿病発症に結びつくことが明らかとなった。

    アルツハイマー病、パーキンソン氏病などに代表される神経変性疾患は、高齢化社会において、生活の質を脅かす疾患の一つである。そかし、その病態の発症・進行の機構は不明な点が多い。bZIP型転写因子のNrf1の欠失マウスは、異常タンパク質の蓄積を伴ったヒトの進行性神経変性疾患に極めて類似した症状を示す。本計画では、Nrf1欠失マウスの解析を通して、その破綻・異常タンパク質の蓄積に至る分子機構を理解することで、ヒトの神経変性疾患に対する新たな知見を得ることを目的とする。 Nrf1欠失マウス由来の神経初代培養細胞を用いたマイクロアレイ解析を実施した。その結果、Nrf1の欠失で発現に影響を受ける遺伝子は、これまでに報告されてきたNrf2が制御する生体防御関連の標的遺伝子とは異なる事が示された。また、Nrf1欠失マウス脳組織においての遺伝子発現解析を実施し、同様の結果を得ている。したがって、Nrf1は、Nrf2とは異なる標的遺伝子の発現制御を介して、神経細胞の恒常性の維持に寄与していると考えられた。Nrf1が直接制御する標的遺伝子の同定を試みるために、Nrf1のクロマチン免疫沈降解析(ChIP)を計画した。ChIP解析に用いる抗体の検討を行ったが特異性の高い抗体は得られなかったので、申請計画に記したように、Nrf1のパートナー因子である小Maf群因子に対する抗体を用いて、ChIPシークエンス解析を実施した。その結果、小Mafの結合部位は、Ataxin-1などの神経変性と関連した遺伝子の制御領域に結合していることが明らかなり、病態発症との関連が示唆された。上記の結果の一部は、学会発表として報告し、また、誌上発表の予定である。

    申請者らは,GATA-1と構造的に高い相同性を有する転写因子であるGATA-2が,GATA-1との機能的相補性を有することを鑑み,GATA-1とGATA-2の機能分担、ネットワーク制御、さらに、それらの合計発現量が血球細胞の運命決定に与える影響を解析する必要があると考える。そこで、これら両者の発現量を個体レベルで明らかにするために、申請書らが既に樹立した、Gata1遺伝子発現制御領域下で赤色蛍光蛋白質(dsRed2)を発現するトランスジェニックマウスとGata2遺伝子座に相同組換え法で緑色蛍光蛋白質(GFP)をノックインしたマウス、及びそれらを交配した複合改変マウスを用いて、以下の解析をおこなった。これらのマウスの造血細胞における蛍光蛋白質発現を、フローサイトメーター(FACS)を用いて定量的かつ定性的に測定し、FACSにより分取した後に、コロニー法などでin vitro分化誘導することにより、その分化能を調べた。また、GATA-1とGATA-2を共発現する細胞の同定と解析を行い、細胞の増殖・分化・アポトーシスにおける2つのGATA因子の発現量を単一細胞レベルで明らかにすることを試みた。さらに、既に樹立されているGata1およびGata2遺伝子の部分破壊マウスや条件付き遺伝子破壊マウス、及びそれらを交配した複合改変マウスをの血液細胞の解析を行い、2つの転写因子の発現量変化が細胞運命に与える影響を調べた。また、レトロウイルス遺伝子導入系を用いて、GATA-1とGATA-2を高中低の様々な発現量で未分化前駆細胞に導入することにより、細胞運命決定に与える影響を検討した。これらの結果、GATA-1、GATA-2の発現量がその機能に大きく影響することが示唆された。

    近年一般的に認知されるに至った活性酸素種や食物に含まれる親電子性物質によりもたらされる酸化ストレスは、DNAやタンパク質、脂質などの生体高分子を酸化することで傷害を与えるため、ガンや糖尿病などの生活習慣病を引き起こす素因になると考えられている。一方、生体内に存在するプロスタグランジンJ_2(PGJ_2)などの生理活性物質もまた、内因性の親電子性物質として作用し炎症の終焉に貢献する。すなわち、酸化ストレスは外来物質や代謝副生成物だけではなく、細胞内情報伝達におけるセカンドメッセンジャーとしても機能している.このような酸化ストレスに対し,細胞はすみやかに生体応答を発動することで、その恒常性維持と適応に努めている.この生体応答の制御機構において重要な機能を担っているのが,Keap1-Nrf2システムである。Nrf2欠損マウスあるいは、Keap1欠損マウスと高脂血症モデルマウスとして、apoE欠損マウスを交配し、それぞれの複合変異マウスにおける動脈硬化の進行について検討している。あるいは、生化学・分子生物学的な解析とマウス発生工学的手法による個体レベルの解析、さらには構造生物学的なアプローチも取り入れて、多角的にKeap1-Nrf2システムによる分子レベルの制御機構を解析した。その結果、動脈硬化におけるNrfr2-Keap1制御系の重要性が明らかになりつつある。

    本研究では,以下の実験を実施した. 1.Nrf2に相互作用する因子の同定:Nrf2に特異的に相互作用する因子として,TIF1β,TIF1γ,BAF53,TRRAPを同定した.また,免疫沈降実験により,BAF53を含むクロマチン構造変換複合体の中心サブユニットであるBRG1とNrf2が相互作用することを見いだした.BRG1のノックダウンおよび一過性過剰発現実験から,BRGIはHO-1遺伝子の発現を選択的に増強することを発見した.さらに,HO-1遺伝子の発現増強には,BRGIによるHO-1遺伝子プロモーター近傍のZ-DNA形成が重要であることを解明した.Nrf2転写制御メカニズムを解析するため,FLAG標識したNrf2,転写活性化ドメインNeh4およびNeh5の欠損変異体,各種アミノ酸変異体をテトラサイクリン誘導性に発現する細胞株を構築し,これらの細胞株を用いて,Nrf2と上記の相互作用因子との結合能,その転写活性化への影響を解析した. 2.Nrf2が転写応答する場の同定および解析:Nrf2転写応答における相互作用因子の影響を調べるために,TRRAPおよびBRG1のノックダウン細胞を作成し,Nrf2標的遺伝子座へのリクルートをクロマチン免疫沈降法により検討した.TRRAPノックダウン細胞では,Nrf2のARE配列へのリクルートが増強していたが,BRG1ノックダウン細胞では,Nrf2への影響は認められなかった.一方,Nrf2ノックダウンによりBRG1のリクルートは消失した.上記のテトラサイクリン誘導性Nrf2発現細胞を用いて,Nrf2標的遺伝子座へのNrf2と相互作用因子のリクルートを検討している.さらに,Nrf2およびFLAGに対する抗体を用いて,Nrf2変異体の核内局在を検討しているところである. 3.DEMに応答するレポーター遺伝子の作製:RNAiライブラリーを用いて,Nrf2の親電子性物質応答に関与する因子をスクリーニングするために,ヒトとマウスNQO1およびHO-1遺伝子のARE配列を含むプロモーター領域に緑色蛍光タンパク質遺伝子またはチミジンキナーゼ遺伝子を連結したレポーター構築を作製した.これらレポーター構築を安定導入した細胞を作製した後に,スクリーニングを開始する予定である.

    1)AHSP遺伝子の5'上流領域プロモーター領域の解析から、赤芽球系分化誘導時には、翻訳開始点上流-328〜-286bpに位置する3カ所の転写因子GATA結合モチーフがAHSPの転写活性化に必要な最小要素であることが明らかになった。EMSA解析等の結果を加え、赤芽球系前駆細胞におけるAHSPの転写にはGATA-1の作用が必須なことが明らかになった。同時に、PrP^<Sc>侵襲によるAHSPの発現抑制には、GATA-1による転写制御が関連することが推定された。 2)プリオン感染マウス由来脳乳剤、あるいはPrP^<Sc>持続感染神経細胞株ScN2a存在下にMELhide8細胞を培養し、AHSP等の発現を解析した。しかし、赤芽球系分化誘導時、AHSPをはじめ、α-グロビン、β-グロビン、GATA-1、EKLF、NF-E2などの転写にはいずれも何ら影響が認められず、また、長期継代後にもMELhide8細胞にはPrP^<Sc>の蓄積が全くみられなかった。これらの結果から、PrP^<Sc>はMELhide8細胞に対する直接作用をもたないことが明らかになった。 3)MELhide8細胞におけるAHSP mRNA発現量、ならびに上記GATA依存性のAHSPプロモーターレポーター遺伝子発現は、IL-6の添加で濃度依存性に抑制された。IL-1βにも類似作用が認められたが、その効果はIL-6に比して低かった。これらの作用は、STAT3経路の抑制により明確に減少した。したがって、赤芽球系細胞におけるAHSPの転写抑制は、プリオン病で増加する炎症性サイトカインによるGATA依存性転写のSTAT3系による抑制を介することが示された。 4)牛末梢血赤血球の細胞質にAHSPが存在することが明らかになった。BSE感染個体由来脳を接種した牛群の末梢赤血球AHSP含量は、健康個体のそれと有意差は認められず、早期診断マーカーとすることは困難なことが判明した。

    エリスロポエチン(Epo)遺伝子発現はhypoxia inducible factor-1(HIF-1)による正の促進とGATAによる負の抑制のバランスにより調節されている。従って、GATA阻害とHIF-1促進の両作用を持つ薬剤が新規Epo促進薬として使用されることが期待される。慢性貧血はinterleukin-1β(IL-1β)およびtumor necrosis factor-α(TNF-α)が増加し、GATA結合活性を増加させることによりEpo産生が抑制される機序が解明された。そこで前回我々はGATA特異的阻害薬(K-7174)の腹腔内投与により慢性貧血のモデルマウスに対する有効性を報告した(FASEB J 17:1742;2003)。さらにGATA結合活性阻害作用かつHIF-1結合活性亢進作用を持つK-11706を見い出しこれを経口投与することで慢性貧血のモデルマウスに有効であることを確認した。K-11706をHep3B細胞に添加することでGATA結合活性を抑制し、HIF-1結合活性を亢進させた。IL-1β,TNF-αによりGATA結合活性は亢進したが、K-11706添加により亢進したGATA結合活性は低下した。またIL-1β,TNF-αによりHIF-1結合活性は亢進したが、K-11706添加によりHIF-1結合活性はさらに亢進した。IL-1β,TNF-αによりHep3B細胞のEpo蛋白産生は抑制された。しかし、K-11706添加によりEpo蛋白産生は回復した。IL-1β,TNF-αによりEpo promoter・enhancer活性を抑制した。しかし、この系にK-11706を添加するとEpo promoter・enhancer活性を亢進させた。ICRマウスにIL-1β,TNF-αを腹腔内投与することにより、Epo産生を抑制し、ICFU-E、網状赤血球数、Hbを低下させた。しかしこの系に同化合物を経口投与するとEpo産生抑制が解除され、1上記パラメーターの改善が認められた。以上よりGATA結合活性阻害かつHIF-1結合活性亢進作用を有するK-11706の経口投与での慢性貧血改善の可能性が示唆された(Blood 104:4300;2004)。 固形腫瘍は、中心部が低酸素になるため、低酸素に反応するhypoxia inducible factor-1(HIF-1)が増加することでHIF-1結合部位(HRE)を5'プロモーターに持つvascular endothelial growth factor(VEGF)が増加し、腫瘍血管が増生する。HIF-1α鎖は大気中では402番目と564番目プロリンが、2-oxoglutarate(2-OX)を補酵素として水酸化されるために、von hippel lindau(VHL)と結合してプロテアゾームでユビキチン化され分解される。しかし低酸素下ではプロリンは水酸化されないため、α鎖は分解されずに、β鎖と結合して核内へ移行し、HREと結合してVEGFあるいはEpo遺伝子発現が亢進する。そこで低酸素下でも2-OXを投与することでHIF-1α鎖を分解してVEGF産生を抑制させることが可能かどうかを、低酸素でVEGFおよびEpoを生産するHep3B細胞を用いて解析した。低酸素での細胞の産生するVEGF蛋白におよぼす2-OXの効果をELISA法で測定した。この結果、2-OXの用量依存性にVEGF産生が抑制された。また、VEGFプロモーター・Epoエンハンサー活性をルシフェラーゼを用いて測定した所、2-OXの用量依存性にVEGFプロモーター活性が抑制された。しかし、VEGFプロモーターのHRE変異体では、2-OXによる抑制は認められなかった。細胞抽出物を用いたゲル・シフト法により、2-OXの用量依存性にHIF-1結合活性が抑制された。またwesternblot法により、細胞の産生するHIF-1蛋白も2-OXの用量依存性に抑制された。さらに、血管新生キットを用い、VEGF添加あるいは低酸素による血管形成を2-OXが用量依存性に抑制した。また、ICRマウス背部にメラノーマ細胞を接種した局所に2-OXを連日注射することで、著明な腫瘍増殖抑制効果を認めた。以上の結果より、HIF-1α鎖のプロリン水酸化の基質となる2-OXは、VEGFプロモーターを介して、VEGF蛋白産生を用量依存性に抑制することを認めた。よって2-OXは新たなVEGF inhibitorであり、今後2-OX抗腫瘍効果が期待される。

    GATA-2遺伝子の血球特異的なプロモーター・第1エクソンの下流に緑色蛍光蛋白質(GFP)遺伝子を挿入したマウス(ノックインノックアウトマウス:G2-GFP)を樹立し,骨髄におけるGATA-2発現細胞の同定および解析を行なった.ヘテロマウスの骨髄では、全細胞の約0.5%の割合でGFP陽性細胞が存在し,これらの細胞は血球分化マーカー陰性(Lin^-),c-Kit^+の造血前駆細胞およびLin^-/c-Kit^+/Sca1^+の造血幹細胞であった.GFP陽性細胞をOP9ストローマ細胞と共培養したところ,30日以上にわたり多系統の血球細胞を産生したことから,この細胞は未分化で増殖能の高い細胞であることが示唆された.このGFP陽性細胞では,c-Myc, Cyclin A2,Cyclin B1等の増殖中の細胞で発現する遺伝子が,GFP陰性細胞に比べて多く発現していた.さらに,Lin^-/c-Kit^+/GFP^+分画には,30%以上の高い割合でS/G2/M期の細胞が含まれていた.これらの結果から,GATA-2は骨髄造血幹細胞および前駆細胞の細胞周期進行に関与する遺伝子発現を制御していることが示唆される. このようなGATA-2の造血前駆細胞の増殖における機能をより詳細に解析するために,loxP配列を両端に有するGATA-2 cDNAをGATA-2遺伝子の翻訳開始部位にノックインする条件付きノックアウトマウスの作成した(G2-CKO).GATA-2ノックアウトマウスは胎生致死となるため,本マウスによってのみ成獣骨髄でのGATA-2の機能を検討することができる.すでに,同マウスをインターフェロン投与により誘導的にCreリコンビナーゼを発現するMx1-Creトランスジェニックマウス,および,上述のGFPノックインマウスと交配し,三重複合体(G2^<GFP/CKO>::Mx1-Cre)を確立している.現在,骨髄移植法を用いた骨髄造血前駆細胞におけるGATA-2の機能関与をGFPを指標として検討する系を立ち上げている.

    細胞癌化とその抑制における転写因子の役割の解明に,血球系転写因子と白血病をモデル系として選択して取り組んだ.転写因子GATA-1による細胞増殖抑制・分化誘導・細胞死抑制の3つの作用は,赤血球前駆細胞から成熟赤血球への分化に必須の貢献を行っている.私たちは,胚幹細胞の解析から,GATA-1発現が野生型の5%レベルに低下した際には,赤血球系への分化誘導能や細胞増殖抑制能は不十分であったが,細胞死抑制能については,同レベルのGATA-1発現で十分であることを見出した.さらに,GATA-1発現を野生型の5%にまで減弱させたノックダウンヘテロマウスは2種類の白血病を発症すること,しかし,GATA-1完全欠失ヘテロマウスはそのような白血病を発症しないことを見出した.GATA-1はX染色体上に位置するため、X染色体の不活化により,GATA-1ノックダウンヘテロマウスには変異アリルが活性化した赤血球前駆細胞と野生型アリルが活性化した赤血球前駆細胞の2種類が存在するが,同マウスでは,前者が分化も細胞死もできないまま増殖蓄積し,高率に白血病を発症する母地となっている.さらに,ダウン症候群患児に好発する巨核芽球性白血病にはN末端領域を欠失したGATA-1がほぼ全例で発現しているが,同白血病を発症した患児より樹立した細胞株に,野生型GATA-1を遺伝子導入すると赤血球系細胞に分化する.一方,N末端領域欠失変異GATA-1(ΔNT-GATA-1)を導入しても同細胞は分化しなかった.すなわち,変異GATA-1の赤血球形質への分化誘導機能の欠失が白血病発症の病因の一つであることが強く示唆される.

    転写因子Nrf2は第2相薬物代謝酵素と抗酸化酵素の誘導に必須であり、変異原物資などの生体異物に対する防御システムに関与している。我々はNrf2欠損状態で突然変異体頻度がどの程度上昇するかを明らかにしようとした。我々は体内突然変異を検出するモデル動物としてgpt deltaマウスを用い、肺中で変異原物質により発生する突然変異の性質を調べた。gpt deltaマウスの気管内に大気中の代表的な変異原物質であるベンゾ[a]ピレン(B[a]P)と1,6-ジニトロピレン(1.6-DNP)をgpt deltaマウスの気管内に投与した結果、投与量に依存して突然変異体頻度は上昇した。1,6-DNPが体内で示す単位重量あたりの突然変異体頻度は31x10^<-5>/mgでB[a]P (1.7x10^<-5>/mg)より高かった。B[a]Pと1,6-DNPによる主要な塩基置換は、それぞれG>TおよびG>Aであり、gpt遺伝子上の突然変異ホットスポットの位置も異なっていた。ディーゼル排気暴露を3mg/m^3の濃度で曝露した結果、対照群の肺中の突然変異体頻度が0.6±0.1x10^<-5>であるのに対して、曝露群では12週間まで突然変異体頻度は直線的に増加した。また、ディーゼル粒子とその抽出物を気管内投与した結果、ディーゼル粒子の変異原性のほとんどが抽出物に由来することが判った。ディーゼル排気曝露とディーゼル粒子による主要な塩基置換はG>Aであり、ホットスポットも1,6-DNPとよく一致したことから、ディーゼル排気の主要な変異原物質はニトロピレンおよびその類似物質であることが示唆された。Nrf2欠損gpt deltaマウスを作製し、Nrf2(+/-)およびNrf2(-/-)マウスの肺にベンゾ[a]ピレン(B[a]P)を気管内投与したところ、Nrf2(-/-)のマウス肺の突然変異体頻度は、Nrf2(+/-)のマウス肺の突然変異体頻度はNrf2(+/-)マウスの2倍に増加した。

    瀬戸は、粘膜関連リンパ組織(MALT)リンパ腫に特異的に認められる染色体転座、t(11,18)(q21,q21)に関与する遺伝子API2-MALT1について、造血器細胞における機能の解析をするために細胞株や骨髄幹細胞にAPI2-MALT1遺伝子を導入した。Hela細胞株や増殖因子依存性の細胞株ではUV刺激、抗がん剤などによるアポトーシスを抑制する能力があることが明らかとなった。また、API2-MALT1と相互作用する蛋白としてTRAF2、smac、HtrA2などアポトーシスを制御する蛋白を明らかにした。また、悪性リンパ腫のゲノム異常をアレイCGHで検索したところ、病型特異的なゲノム異常が存在することが明らかとなった。 森下は、Evi1転座関連遺伝子の機能を明らかにするためにEvi1遺伝子欠損マウスの造血発生異常を検討し、造血幹細胞の維持・増殖異常及び、血管発生異常を同定した。遺伝子発現解析にてGATA-2遺伝子の転写低下、プロモーター解析によりEvi1はGATA-2の直接の転写調節に係わることがわかった。Evi1は白血病細胞内にてGATA-2転写を亢進させ、白血病幹細胞の増殖維持に関係していることが示唆され白血病発症機構の一端を解明した。t(1,3)転座関連遺伝子としてEVI1遺伝子ファミリーであるMEL1遺伝子を単離し、機能解析によりEVI1と同様の転写因子機能を持っていることがわかり白血病発症機構も類似することが示唆された。

    分化方向性の制御を維持するモデルとして,造血幹細胞を選び,以下の解析を行った. (1)造血幹細胞の自己複製能維持に必要な転写因子を同定することを目指し,幹細胞の維持に重要と考えられる転写因子GATA-2の発現制御機構を解析した.GATA-2遺伝子の発現をGFPレポータータンパク質で解析できるトランスジェニックマウスを作製し,9.5日胚のpara-aortic splan chnopleura,同13.5日胚の胎児肝でのGATA-2遺伝子の発現を解析した.その結果,GATA-2遺伝子の転写制御に必須なシスエレメントを含む領域を同定することに成功した.現在,さらに結合領域を絞り込むために,同トランスジェニック法とin vivo footprint法による解析を行っている.今後は,その結合配列に対するトランス因子を同定するために,One-Hybrid法を行うことを予定しており,フローサイトメトリーにて分取したGFP陽性細胞からcDNAライブラリーを作成中である. (2)造血幹細胞の性質を有した細胞株を作成することは,幹細胞自体の稀少性の点から,今後の解析にたいへん有用である.そこで温度感受性T抗原を,胎児造血幹細胞に発現しているトランスジェニックマウスの作製に取り組み,成功した.今後,同トランスジェニックマウスから得られる血液幹細胞を用いて,血液細胞系の分化に重要な転写因子群の発現プロファイルを網羅的に解析し,分化の方向に働く転写因子群とその拮抗因子群を同定する予定である.同定後,分化に拮抗する因子群を,レトロウイルス系を用いて,分化抑制状態にある各種培養細胞や,分化抗原を発現する骨髄細胞に導入し,分化/脱分化の制御を試みる.

    本研究は、赤芽球系細胞における赤血球膜骨格組み込みの"ユニット工法仮説"実証を目的とする。骨髄赤芽球系細胞、赤芽球系培養細胞を用い、遺伝子導入とタンパク質の生化学的・形態学的解析で以下の成果を得た。 ●赤芽球系培養細胞K562を用いて、膜骨格と相互作用する主要膜タンパク質、バンド3、グライコフォリンC、アンキリン、プロテイン4.1、ならびにそれらの変異体の安定発現系を構築し、細胞内局在と赤芽球分化誘導時の挙動や細胞分化・増殖に及ぼす影響を検討した。膜内在性であるバンド3とグライコフォリンCはともにER/Golgiを経て細胞膜に移行した。これらと膜骨格を連結すると考えられるアンキリンとプロテイン4.1も同様にERとGolgiに局在が認められ、これは赤芽球系分化誘導後にも変化しなかった。また、内因性のアンキリンやプロテイン4.1、さらにスペクトリンも主にER/Golgiに分布が認められた。したがって、膜骨格組み込みは赤芽球系細胞の細胞膜ではなく、ERで生じる現象であることが明らかになった。 ●同様の解析で、K562細胞におけるバンド3分子の恒常的発現により細胞増殖速度が約70%に低下すること、誘導剤による赤芽球系分化速度も低下する現象が見出された。しかし、誘導可能な赤芽球までのステージでは、細胞骨格タンパク質の局在や細胞形態に対する影響は認められなかった。 ●骨髄赤芽球系前駆細胞ではスペクトリン等の膜骨格タンパク質の合成とER/Golgiと思われる膜画分への移行がまず生じ、次いでバンド3等の合成と細胞膜での発現が観察された。膜骨格タンパク質の分布は脱核前後で急激に変化した。 以上のように、本研究からは、膜骨格タンパク質の組み込みが細胞内小器官の膜上で既に生じることが明らかになった。ただし、その細胞膜への移行がいわゆる小胞輸送による"ユニット"としてか否かの検証には、新たな手段を講じる必要がある。

    本研究は、赤血球の増殖・分化・アポトーシスの制御とその破綻がもたらす造血器腫瘍の形成過程において,血球系GATA転写因子が果たす役割を解明することを目的として行っている.本年度は,GATA-1遺伝子ノックダウンマウス雌ヘテロ接合体(GATA-1.05/X)に発症する白血病の病態について,GATA-1.05/X574例と野生型225例について検討した.その結果,GATA-1.05/Xは平均寿命388日であり,野生型と比較して有意に短命であった.死亡マウスのうち,観察し得た98例全てに脾腫大が観察された.死亡時期は100日前後と350日以降の2峰性のピークを呈し,前者はc-kit陽性の赤芽球細胞系列の,後者はCD19陽性のBリンパ球系列の異常増殖が観察された.c-kit陽性白血病細胞は形態的に未分化であり,in vitro培養系で分化誘導が可能であった.一方CD19陽性細胞に伴う白血病は脾臓のほか全身のリンパ節腫大を伴っており,ヒト骨髄異形成症侯群類似の表現型を呈していた.また,トランスジェニックレポーターマウスを用い,GATA-1,GATA-2遺伝子の時期・細胞系列特異的な発現制御機構の解析を進めた.GATA-1遺伝子については赤血球への発現を再現性良く示す人工的なGATA-1 minigeneを開発し,GATA-1 hematopoietic enhancer(G1HE)のコア配列と,IEの5'側にそれぞれ存在するdoubleGATA配列とCACCC配列が,いずれもG1HRDの機能に必須であることを見出した.また,GATA-2の造血組織における発現を再現性よく示すレポーターマウスを解析し,GATA-2遺伝子の発現制御機構が,para-aortic splanchnopleuraや卵黄嚢を中心とする初期造血の時期と,胎児肝の時期とで異なっていることを明らかにした.

    ヒトErythropoietin(Epo)遺伝子のプロモーター領域に存在するGATA配列にGATAが結合してEpo遺伝子発現を負に制御している。また、エンハンサー領域にHIF-1が結合してEpo遺伝子発現を促進している。この事実のもとに以下の研究結果を得た。 1)腎不全で著増するN^G-monomethyl-L-arginine(L-NMMA)に着目し、Hep3B細胞の実験系を用いて解析した。この結果、NOS拮抗阻害薬であるL-NMMAによりNO・cGMP産生は阻害され、さらにGATA結合活性・mRNA発現レベルが亢進することによりEpo遺伝子発現が抑制されて腎性貧血が発症することを認めた(Blood 96:1716-1722,2000)。この系にL-arginineを前処理することで腎性貧血が改善されることを認めた(Kidney Int 61:396-404,2002)。 2)H_2O_2はEpo遺伝子発現を抑制するが、HIF-1α鎖の不安定化させると共にGATA結合活性を亢進させることの両機序によることを認めた(J Cell Physiol 186:260-267,2001)。 3)カドミウムによるEpo産生抑制の機序は、HIF-1結合活性の低下によるためであり、GATAの関与は認めなかった(Arch Toxicol 77:267-273,2003)。 4)マウスEpo遺伝子のプロモーターは解明されていなかったが、ヒトEpo同様にプロモーター領域のGATA配列にGATAが結合してマウスEpo遺伝子発現を抑制していることを認めた(Int J Hematol 74:376-381,2002)。 5)睡眠時無呼吸症候群の重症例を用い、一過性の低酸素刺激による生体のEPO・VEGF反応を解析した結果、重症化するにつれHbが増加するとともにVEGFは約5倍増加したが、Epoは1.6倍と低く一過性の低酸素刺激による反応様式の相違を認めた(Blood 98:1255-1257,2001,Blood 99:393-394,2002,Respiration 71:24-29,2004)。 6)慢性貧血モデルマウスにGATA特異的阻害薬であるK-7174を静脈注射することにより慢性貧血が改善されることを認めた(FASEB J 17:172-1741,2003)。 Epo遺伝子の発現に関わるkidney inducible element(KIE)を解明する目的で、BACを用いたトランスジェニックマウスでの解析により、Epo発現細胞は腎臓の近位尿細管周囲間質細胞であり、KIEは-22Kbpから-8Kbp上流域に存在することを確認した(In preparation)。

    (目的)thioredoxin(TRX)遺伝子の活性化機構の情報を利用してTRXの機能解祈を行う。 (成果)1.TRX遺伝子のヘミンやtertial butylhydroquinone(tBHQ)などのeletrophilesによる活性化機構にはantioxidant responsive element(ARE)を介した転写因子Nrf2による調節が重要であることを示した。また、AREの活性化調節にTRXによるredox調節機構が重要な役割を果たすことを明らかにした(JBC,2001;Oncogene,2003)。これらの知見は、赤血球分化、虚血再還流障害や化学発癌に対する生体防御におけるTRXの役割を示唆し、ヘムや化学物質によるシグナル伝達機構の解明につながると考えられる。 2.TRX遺伝子の神経成長因子NGFによる発現誘導機構へのcyclic AMP responsive elementおよびCREBの関与を明らかにした。さらに、NGFによるPC12細胞の神経突起伸長およびシグナル伝達にTRXが必須の役割を果たすことを明らかにした(J. of Neuroscience, 2003)。 3.マウスTRXゲノムをクローニングしてこれらのpromoter制御情報をもとにしてTRXノックダウンマウス作成準備を継続している。また、TRX遺伝子の発現を抑制するRNAiベクターを作成した。さらにTRXのnegative regulatorであるTRX binding protein-2(TBP-2)の解析を行い、transgenic,knock out miceの作成を開始した。 4.酸化ストレスによる細胞死の機構を明らかにした(EMBO J., 2002.)。また、多環芳香族化合物メチルコランスレンによるアポトーシスの機構を初めて明らかにした(JBC, 2002)。

    血小板形成における小Maf群因子の機能を明らかにするために,以下の実験を行った. (1)小Maf群因子の下流で機能する血小板形成機構を担う分子の同定.巨核球からの胞体突起形成に異常が認められる小Maf群因子欠損マウスの巨核球と,野生型巨核球の間で発現に差がある遺伝子を明らかにするために,サブトラクション法を行った.その結果,アクチンや,チュブリンなどの細胞骨格に関係した遺伝子が,変異巨核球において減少していた.また,新規分子として,クローン#325を同定した.同因子は,未分化幹細胞や赤血球系細胞では発現が低いが,巨核球への分化に伴い発現が上昇することが明らかになった. (2)巨核球を利用した小Maf群因子の構造・機能連関の解析.小Maf群因子は,ヒト,マウス,トリ,カエル,フグに至る多くの脊椎動物におて存在しており,bZip構造以外にも,そのアミノ末端側領域,カルボキシル末端側領域が良く保存されている.そこで,MafGのカルボキシル末端側の欠失変異分子を作製し,その性質を,in vitro, in transfecto,そして,トランスジェニックマウスを用いたin vivoの実験系で解析した.これまでにin transfectoの結果として293T細胞に対する一過性遺伝子導入実験から,C末端欠失分子は,野生型分子に比べて,転写活性化をしやすい傾向があることが明らかになった.また,巨核球における過剰発現マウスでは,野生型分子も欠失分子も巨核球からの胞体突起形成を抑制したが,その抑制の程度は,欠失分子では軽度であることが示された.

    マウスのBTEBとBTEB2は亜鉛フィンガーモチーフを3回繰り返しもつ、GCbox結合性の転写因子である。これらの生体における機能を明らかにするために遺伝子を単離しての第一エクソンをβ-galとneo遺伝子に置き換えたターゲティングベクターを作成し、常法に従いBTEBとBTEB2遺伝子の欠失マウスを作製した。BTEB(^-/_-)マウスは雌、雄共にメンデルの法則に従って正常に生まれて来て、生育も野性型と見かけ上変わらなかったが、BTEB2(^-/_-)マウスは雌、雄共に生まれて来ないことが分かった。従って、胎児の解析を行った結果、受精後3.5日までは見かけ上正常に発生するが、着床後に致死になることが分かった。その原因を検討した結果、FGF4の発現が低下していることが分かった。FGF4は胎児の発生で重要な役割を果たしており、FGF4の遺伝子欠失マウスは胎児発生の初期に致死になることが報告されているので、少なくともこの遺伝子の発現低下が、BTEB2欠失マウスの致死の原因であると考えられた。FGF4遺伝子の上流のプロモーター領域にはBTEB2結合配列のGCbox配列があり、chromosome immunoprecipl itation法によって、発生初期マウス胎児のFGF4のGCbox配列にはBTEB2が結合していることが明らかになった。BTEB欠失マウスは正常に生まれて来て見かけ上、野性マウスと変わらないが、BTEBは小脳のプルキンエ細胞と海馬に特徴的な発現パターンを示したので、マウスの行動と記憶の解析を行った。その結果、小脳の働きに関連していると考えられる回転棒テストと海馬の状態に関連する記憶を調べるcontextual fear conditioning testで野性型マウスと比較して明らかに機能の低下が観察された。

    (1)AhR及びNrf2遺伝子機能を増強したトランスジェニックマウスの作製 AhRをkeratin14のプロモーターにより発現させたトランスジェニックマウスを作製した.高発現ライン2ラインにおいて,皮膚の炎症と角化の亢進が観察された.(2)ヒト型ダイオキシン受容体マウスの作製 ダイオキシン類に対する感受性とその生体に対する影響は,動物種により著しく異なることが知られている.ヒトにおける感受性と影響のモニタリングを可能にする動物モデルを作製する目的で,マウスダイオキシン受容体の代わりに,ヒトダイオキシン受容体を有する,ヒトダイオキシン受容体(hAHR)ノックインマウスを作製し,その薬剤に対する反応性を調べた.3-メチルコラントレンに対する反応は,hAHRノックインマウスもコントロールマウスも同程度であったが,TCDDに対する反応は前者の方が弱いという結果であった.この結果は,ダイオキシン受容体のリガンドによる反応の特異性が,種により異なること,そして,hAHRノックインマウスがヒトの反応の特異性を再現できる有用なモニター動物として利用可能であることを示唆するものである.(3)AhRおよびNrf2遺伝子欠失マウスの環境異物に対する反応の解析 Nrf2欠失マウスでは,異物代謝系第2相酵素群の誘導が欠落していることから,様々な外来の化学物質により障害を受けやすいことが予測された.解熱鎮痛消炎剤として頻用されているアセトアミノフェン.を投与したところ,Nrf2欠失マウスでは急性肝障害が高頻度に誘発された.また,ディーゼルエンジンの排気ガスに曝露したところ,Nrf2欠失マウスではDNAの塩基の修飾(DNAアダクト)が高頻度に生成されていることが明らかになった.さらに,ベンツピレンの胃内投与によりNrf2欠失マウスではより高頻度に胃癌が発生することが示された.以上の結果から,Nrf2が,実際に生体において,外来の化学物質の代謝に重要な役割を果たしていることが証明された.

    毒性化学物質のバイオモニター系開発を目的に,外来異物に対する生体の応答機構を利用したモデル動物の作製を試みた.利用したのは,化学発癌の主因である親電子性物質に応答した生体防御遺伝子群の転写誘導機構である.これらの遺伝子の転写制御領域又はその制御を司る転写因子Nrf2の活性化機構の活用し,マウスとゼブラフィッシュを用いたモニター系構築を目指した.親電子性物質センサーからのシグナルは,Nrf2のN末に存在するNeh2ドメインに伝わり,何らかの機構によりNrf2の蛋白質安定化と核移行に促し,標的遺伝子の転写活性化に帰結する.Nrf2のN末半分にLacZ遺伝子を融合した構築をNrf2遺伝子座に挿入したマウス(Nrf2-LacZマウス)を作出したところ,親電子性物質を混ぜた餌の供与で通常検出できない小腸吸収上皮におけるLacZ発現が著名に誘導された.このことは,食物や医薬に混入する有害化学物質の検出に当該マウスが有用であることを示すとともに,Nrf2のN末に蛋白質安定性に関わる領域があることを指摘した.この領域をGFP融合蛋白質を利用して探索したところ,Neh2ドメインが浮かび上がった.一方,生体防御遺伝子であるNQO-1,GSTP, HO-1の転写制御領域を単離し,これにGFP遺伝子を融合した構築をもつトランスジェニックマウス及びゼブラフィッシュの系統化を試みた.一過性のレポーター解析により,各構築の親電子性物質に対する応答能は確認できた.現在,ゲノムに同構築を安定にもつ系統の作製を試みている.計画遂行中の社会変化により,哺乳動物の大量殺戮は困難な情勢となってきたので,培養細胞を用いたモニター系の開発にも取り組むことにした.前述のNrf2-LacZマウスから繊維芽細胞を樹立したところ,親電子性試薬に対するLacZ誘導能を確認できた.現在,GFPを用いた系も立ち上げつつある.

    ●培養細胞系の確立:レトロウイルスベクターを用いて、K562、およびHEK293細胞における正常牛赤血球型バンド3(bebWT)、ならびにバンド3完全欠損症における変異バンド3(bebRX)、またそれらのEGFP融合タンパク質の安定発現系を構築した。さらに、これらの細胞系でバンド3に加えアンキリンのバンド3結合領域(AnkN90)を発現する細胞株を確立した。 ●上記の各細胞を用い、bebWTが細胞膜に輸送され安定化すること、一方、bebRXはレトログレードトランスポートを含む細胞内小胞輸送を経て細胞質ユビキチン・プロテアソーム系により合成後速やかに分解されること、さらにbebWTとbebRXが同時に存在すると、それらの相互作用によりbebWTもが分解され安定性が低下する、即ち、bebRXがbebWTの発現に対してドミナントネガティブに作用することを明らかにした。諸種の小胞輸送阻害剤、あるいは形態学的観察により、これらがER、ならびにGolgiにおいて生じることを示した。同様に、バンド3とアンキリンの相互作用・結合はER、あるいはGolgiにおいて既に生じることを明らかにした。一方で、アンキリンはバンド3非存在下でも小胞に結合することも明らかとなり、この結合を介して膜骨格を形成し得るものと考えられた。 ●正常個体、欠損症個体由来の骨髄細胞におけるバンド3、アンキリン、スペクトリン、プロテイン4.1等の時空間的発現と配置との観察により、バンド3とアンキリン間のみならず、これら主要膜骨格タンパク質の相互作用がER/Golgi膜上で生じ得る可能性を示した。プロテイン4.1の小胞との結合については、一部リン脂質を介するものがあることを明らかにした。 ●これらの成果に基づき、膜骨格の細胞膜への組み込みは、赤芽球の細胞内小胞においてスタートすることが示された。これがいかにして細胞膜のネットワークへと構築されるのかは今後の課題である。

    今年度は以下の成果を得た. (1)bZipネットワークの標的遺伝子の探索 mafG-/-::mafK+/-マウスの巨核球は,血小板形成の主たる過程である胞体突起形成が著明に障害されている.小Maf群因子の下流で機能する因子で,血小板の放出に重要な因子を明らかにするために,mafG-/-::mafK+/-マウスの巨核球のmRNAと野生型マウス巨核球のmRNAとのあいだでサブトラクションを行った.その結果,アクチン,チュブリンなどの細胞骨格系の遺伝子が得られた.また,新規の因子clone325を得ることができた.clone325は,赤血球系細胞で発現が低いのに対して,巨核球系細胞において発現量が多いことが明らかになった.この発現プロファイルから,同因子は,巨核球の分化・成熟,血小板の放出過程において重要な機能を果たしている可能性が大きいと考えられる. (2)神経細胞におけるbZipネットワークの機能解析 mafG-/-::mafK+/-マウスは,生後8週目あたりから重度の運動障害を発症する.この症状はヒトのHereditary Hyperekplexiaに類似していることから,その原因遺伝子として報告されているグリシンレセプターmRNAの発現を,同マウスの神経組織において調べたところ,その発現は約3分の1程度に減少していた.これにより,神経細胞において,bZip制御ネットワークの下流にグリシンレセプター遺伝子が存在することが明らかになった. (3)Bach因子の核局在に対する,小Maf群因子の機能 mafG-/-::mafK+/-マウスの神経細胞のMARE結合活性を検討したところ,Bach/小Mafヘテロ2量体が顕著に減少していた.これは,興味深いことに,Bach因子の核局在が阻害された結果であることが明らかになった.小Maf群因子には,Bach因子の核内移行を促進する作用があり,それは小Maf群因子のbZip構造に依存していることがわかった.

    我々が以前クローン化した2種類の酸化ストレス誘導タンパク質であるMSP23(PrxI)とA170、それに良く知られているストレスタンパク質であるヘムオキシゲナーゼ-1(HO-1)に関して、ストレス剤による誘導現象の解析を中心に研究した。我々は、抗酸化/親電子試薬応答配列(ARE/EpRE)と相互作用する転写因子Nrf2がこれらのタンパク質の誘導現象に深く関与していることを本学基礎医学系伊東健らが作成したnrf2遺伝子破壊マウスを用いて世界で初めて明らかにした。まず、腹腔マクロファージを用いて活性酸素や親電子試薬、カドミウムなどによるPrxI、A170とHO-1との誘導がNrf2に依存して転写誘導されることを証明した。次に、マウスにグルタチオントランスフエラーゼ(GST)などの異物代謝系酵素群の誘導剤であるt-ブチルハイドロキシアニソール(BHA)を経口投与することによりGST同様、肝臓と小腸にPrxIがNrf2に依存して誘導されることを初めて証明した。この結果は、PrxIが生体内においてもNrf2の制御を受けることを示している。このように我々は、本研究プロジェクトを通して、転写因子Nrf2とARE/EpREエンハンサー配列を中心とする親電子試薬応答系は、外界から入る薬物の解毒系に加えて広く抗酸化ストレス応答系の複数の遺伝子の発現を制御していることを明らかにした。さらに、外界から入る異物とは異なる内在性のNrf2活性化因子として、酸化LDLと4-hydroxynonenal(HNE)を同定した。これらの研究成果は、活性酸素や親電子試薬が関与する発ガン、動脈硬化、痴呆、虚血再還流による組織障害の予防法の確立に発展することが期待できる。ことも今後の医学的応用研究への発展を示唆する重要な知見である。

    マウス胚性幹細胞から血液細胞への分化誘導法と、テトラサイクリンによるコンデイショナル遺伝子発現系を組み合わせて、GATA-2の機能解析をおこなった。その結果、GATA-2は未分化な造血前駆細胞の増殖を亢進させること、また赤血球・巨核球への分化を促進することがあきらかになった。また、GATA-1の機能ドメインを解析するために、GATA-1ノックダウンマウスの致死性をGATA-1遺伝子の発現制御領域制御下に種々のGATA-1変異体を発現するトランスジェニックマウスにより相補する実験をおこなった。その結果、Cフィンガー,Nフィンガーは両方とも個体レベルでのGATA-1機能に必須であることがあきらかになった。 mi遺伝子座がコードするbasic-helix-loop-helix leucine zipper型転写因子(MITF)はbasic domainの1アミノ酸の異常では抑制性の機能をもつのに対し、大半のアミノ酸を欠損することであらゆる機能を失った。また、MITFと結合するタンパク質としてzinc finger domainをもつMAZRを単離した。MAZRはマスト細胞で高発現しているプロテアーゼ遺伝子の転写活性をMITFと相乗的に高めていた。また、骨芽細胞分化、破骨細胞分化、骨形成におけるCbfa1の機能およびB細胞分化におけるBach1の機能を明らかにした。 AML1の成体における機能を明らかにするため、AML1のコンディショナル・ノックアウトマウスを作製し、T細胞特異的AML1欠損マウスおよびB細胞特異的AML1欠損マウスの解析を行った。T細胞特異的AML1欠損マウスは著しい胸腺低形成を示し、CD4,8陰性(DN)分画内ではCD25陽性CD44陰性(DN3)分画に細胞が蓄積し、それ以降の分化が抑制されていた。また、B細胞特異的AML1欠損マウスにおいてもB細胞の分化障害を認めた。 以上のように、種々の血液細胞系列における転写因子の機能を明らかにすることができた。

    今年度は以下の成果を得た. 1)親電子性物質・活性酸素種によるNrf2蛋白質蓄積の分子機構の解析 Nrf2が親電子性物質により蓄積するメカニズムを腹腔マクロファージを用いて調べた。親電子性物質とプロテオソーム阻害剤にはNrf2蓄積に対する協調効果が認められなかったことより、新電子性物質は、プロテオソーム阻害剤と同じ経路でNrf2を蓄積することが示唆された。さらに、Nrf2の半減期が親電子性物質により延長することより、新電子性物質がNrf2を安定化することが明らかになった。Keaplとの相互作用に重要であるNeh2ドメインを用いたNeh2-GFP融合蛋白質の半減期は,GFP蛋白質やNeh5-GFP蛋白質に比較して著明に短縮していることより,Neh2ドメインが,Nrf2蛋白質の分解に寄与することが示唆された。 2)Keapl遺伝子破壊実験によるKeaplの生体機能の解析 Keapl遺伝子破壊マウスを作製して,肝臓におけるNrf2の蓄積を調べたところ,同因子が著明に蓄積していることが明らかになった.また,Nrf2の標的遺伝子である異物代謝系第2相の酵素群の発現が上昇していることも明らかになった.さらに,Keapl :: Nrf22重欠損マウスでは,これらの酵素の誘導が認められず,Keapl遺伝子欠損マウスの表現型は,Nrf2の過剰状態を反映していることが示された.以上により,Nrf2の活性は,Keaplにより負に制御されていることが個体レベルで証明された.

    赤血球分化に必須な転写因子GATA-1は、種々因子とさまざまな「橋渡し分子」複合体を形成することにより、複数の機能を発揮していると予想される。本研究では、GATA-1の標的遺伝子候補であるGATA-1遺伝子自身の転写制御領域を鋳型として用い、ゼブラフィッシュ胚に対する生体レポーター解析を行うことにより、生理的な条件下で活性をもつGATA-1「橋渡し分子」複合体の作用機序と分子的実体の解明を試みた。 まず、ゼブラフィッシュGATA-1ゲノム遺伝子を単離同定し、その翻訳開始点上流8kbにGFP遺伝子をレポーターとして接続したコンストラクトを構築した。この構築をゼブラフィッシュ胚に注入したところ、内因性のGATA-1発現を再現するGFP発光を示したので、この構築をゲノムに安定に組み込んだトランスジェニックフィッシュの系列を作製した。次に、このGATA-1-GFPレポーターフィッシュ胚に対して、GATA-1の過剰発現を行なった結果、体節期において異所的なGFPの発現誘導が観察された。種々の変異GFPレポーター構築を用いた結果、このGFP発現誘導には、翻訳開始点上流約6kbに存在するGATA配列が重要であることがわかった。このことはGATA-1遺伝子の発現における正のフィードバック機構の存在を示唆するとともに、GATA-1遺伝子がGATA-1の直接の標的遺伝子であることを個体レベルで初めて示すものとなった。このGFP発現誘導に必要なGATA-1蛋白質ドメインを明らかにするために、種々の変異GATA-1構築を準備し、過剰発現解析を行なった結果、GFP誘導には2つのZnフィンガーがともに必要であることがわかった。N末側のZnフィンガーは、FOGなどの因子と相互作用することが報告されており、他の因子との相互作用の必要性が示唆された。

    1)個体レベルでのGATA因子群の機能解析:GATA転写因子群は良く保存されたDNA結合領域を有しており,それぞれの転写因子にどのような機能の違いが存在するかは,未だに明らかになっていない.そこで,上述のGATA-1発現制御領域を用いて,それぞれのGATA因子を同じ場所・タイミングでGATA-1欠損個体に発現させ,それによって引き起こされる表現型の違いを解析することにより,GATA因子間に存在する機能の類似性と特異性を明らかにすることを試みた.その結果,GATA-1欠損個体はGATA-2でも,GATA-3でもレスキューされることが明らかになった.一方,それらのレスキュー個体では,GATA-1でレスキューされた個体と比較して明らかな貧血があり,GATA-1とGATA-2,3とには明らかな機能的な違いも存在することが示唆された. 2)個体レベルでの転写因子蛋白質のドメイン解析:我々はGATA-1遺伝子の発現制御領域の解析を通じて,すでに赤血球系におけるGATA-1の発現に必要十分な制御領域を同定している.この制御領域を用いて,GATA-1蛋白質の各ドメインの機能を個体レベルで解析した.その結果,培養細胞レベルの解析で同定された転写活性化ドメインは,生体内における赤血球分化において必要ないことが明らかとなった. 3)GATA因子群の転写制御:GATA転写因子群の発現に対して行われている転写調節様式をトランスジェニックマウス系を用いて個体レベルで検討した.GATA-1,GATA-2のそれぞれの細胞系列(赤血球・巨核球・マスト細胞・好酸球)での発現に必要なシスエレメントの同定を行い,GATA-1の赤血球と巨核球における発現には,個別の制御領域が必要であることを明らかにした.

    多細胞生物における高次生命現象の分子的基盤を理解するためには、転写因子レベルでの遺伝子発現調節機構を解明することが不可欠である。個体発生や細胞系列の分化などを分子レベルで理解するために、本研究では発生・分化を時間軸に沿った遺伝子発現カスケードの流れとして捉え、転写因子がそれぞれの細胞系列、発生時期で細胞増殖・細胞死・分化などにどのように関与しているかを検討した。具体的には、以下のような研究結果を得た。1.コリプレッサーSkiの関連遺伝子産物Snoの変異マウスを作製・解析し、もともと発がん遺伝子産物として見い出されたSnoががん抑制因子としても機能することを明らかにした。2.促進性bHLH型転写因子Math3とMash1はニューロンへの分化決定因子として機能することが明らかになった。両者はお互いに補いあって幹細胞からニューロンへの運命決定を行うことが明らかとなった。3.転写因子Pitx2の発現は左側でのみ発現するが、この左側特異的なな発現はNodalシグナル伝達経路によって誘導され、転写因子NkxZによって維持されることが明らかにされた。4.lRF-1は新規の高発がん感受性遺伝子であるが、癌抑制に関わるlRF-1及びp53の標的遺伝子の同定を進め、その過程でp53依存性に転写誘導される新規遺伝子Noxaを単離した。5.遺伝子制御領域内のGATA配列を認識するDNA結合蛋白GATA-3はそのアセチル化状態が変化することにより生体内でのT細胞の生存およびホーミングを制御することが示された。6.転写因子小Maf群因子が,その存在量により,MAREを介する転写を正にも負にも制御し得ることが,トランスジェニックマウスと遺伝子破壊マウスを用いて巨核球における小Maf群因子の発現量を操作することにより,証明された。

    本研究の目的は、赤血球型5-アミノレブリン酸合成酵素(ALAS-E;遺伝子名はAlas2)の遺伝子破壊マウスを作成し、その解析を通して、ヘム合成系の疾患の病態を理解することである。この目的を達成するために、ALAS-E遺伝子破壊マウスを作成し、その解析を行った。その結果、ALAS-E遺伝子破壊マウスは胎生致死であり、死因は一次造血でのヘム合成障害による貧血によることが明らかになった。ALAS-E欠失ES細胞を含むキメラマウスでは、骨髄中にX染色体連鎖性鉄芽球貧血で高頻度に認められる環状鉄芽球が確認された。これらはALAS-E欠失ES細胞に由来するものと予想される。これらの結果は、造血組織における細胞内鉄代謝はヘムによる制御をうけていることを示すものである。次に、ALAS-E遺伝子破壊マウスに対して、ヒトのX染色体連鎖性鉄芽球貧血患者と同じALAS-E変異分子を発現するトランスジェニクマウスを作成し、それらマウスを交配した。この結果、ALAS-E遺伝子破壊マウスの表現型が部分的にレスキューされたが完全なレスキューには至らなかった。遺伝子発現制御領域としてはGATA1遺伝子の制御領域を使用したため、赤血球系細胞におけるALAS-E分子の発現については問題がないものと考えられる。したがって、ALAS-E分子の変異に起因するその活性低下により、完全なレスキューがかからなかったものと考えられる。本研究により、赤血球造血におけるヘム代謝の重要性がマウス個体レベルで明らかになった。さらに、最近に至り、ALAS-N欠失マウスの作出にも成功し、併せて、ヘム合成と鉄代謝についての解析系として有用なマウスが創出された。

    1.転写因子の転写制御 GATA-1、GATA-2、mafKそれぞれの遺伝子の転写制御機構を、トランスジェニックマウスを用いたレポーターアッセイにより解析した。その結果、造血細胞におけるGATA-1遺伝子の発現制御領域(G1HE)、血液幹細胞と神経管におけるGATA-2遺伝子の発現制御領域、造血細胞と心筋細胞におけるmafK遺伝子の発現制御領域(HCEK)をそれぞれ同定した。G1HEの機能には、GATA配列が必須であり、GATA-1遺伝子の自分自身に対する正のフィードバック制御が存在することが示唆された。また、HCEKの機能もGATA配列に依存しており、mafK遺伝子は造血細胞におけるGATA-1の標的遺伝子であると考えられた。 2.GATA-1の機能 G1HE(上述)の制御下にGATA-1、GATA-2、GATA-3あるいはGATA-1の様々な変異体を発現するトランスジェニックマウスを作成して、これらをGATA-1遺伝子破壊マウスと交配し、貧血による胎生致死というGATA-1遺伝子破壊マウスの表現型をレスキューできるかどうかを検討した。GATA-1と同じプロファイルで発現するGATA-2とGATA-3は、いずれもGATA-1欠損マウスをレスキューできた。また、培養細胞の実験から同定されていた転写活性化領域を欠損するGATA-1変異体でも、GATA-1欠損マウスをレスキューできた。これにより、GATA-1遺伝子の制御機構がGATA-1の機能の重要な基盤になっていることと、培養細胞レベルで検討された分子機能は、必ずしも生体における本来の機能を反映しないことが明らかになった。 3.小Maf群因子の機能 NF-E2は赤血球系細胞の分化に必須の因子であると考えられてきたが、個体レベルでのその重要性は未だに不明であった。我々の作成したmafK:mafG2重欠損マウスにおいて、赤血球膜蛋白質の発現異常が検出され、小Maf群因子が赤血球の膜形成過程において必須の因子であることが明らかになった。これは、赤血球系細胞においてNF-E2を構成する因子の重要性が示された最初の例である。

    小Maf群蛋白質はbZip構造を持ち,ホモ2量体,あるいは,CNC群,Jun群,Fos群蛋白質とへテロ2量体を形成し,Maf recognition element(MARE)に結合する.これらbZip構造を持つ転写因子間に形成されるネットワークが,細胞の増殖,分化,そして,癌化において重要な機能を果たしていることが,これまでの解析から示唆されている.我々は,先に,小Maf群蛋白質であるMafKが赤血球系培養細胞の分化を促進することを見い出した.この結果から,小Maf群蛋白質を、形質転換細胞の分化誘導をもたらす因子として利用することを考え,以下の実験を進行させており,後述する結果を得た. 1) MafK過剰発現マウスの作成 正常細胞でのMafK過剰発現の影響を調べるため,赤血球系細胞とTリンパ球それぞれの細胞系列で特異的にMafKを過剰発現するトランスジェニックマウスを作成した.いずれの細胞系列においても細胞数の減少と終末分化が抑制される傾向が認められた.培養細胞でのMafK過剰発現実験の結果から,細胞数の減少は,前駆細胞の初期分化の亢進に伴い,その増殖が不十分になることに起因すると考えられる. 2) 形質転換細胞におけるMafKの過剰発現実験 形質転換細胞としてヒトの神経芽細胞種を用いてMafKを過剰発現させる実験を進行させつつある.神経細胞の分化マーカーを指標にしてMafK過剰発現の影響を検討する予定である.

    エリスロポエチン(Epo)遺伝子は、ヘム蛋白である酸素センサーを介して転写因子の均衡によりその発現が調節されている。我々は、Epo遺伝子上CAP部位より-30bp上流のGATA配列にGATA転写因子が結合してEpo遺伝子発現を負に制御していることを報告した。またH_2O_2をHep3B細胞に添加するとEpo蛋白が低下するがその機序として、GATA転写因子のプロモーター活性が亢進し、GATA発現レベルが亢進することによりEpoプロモーター活性」が低下し、Epo遺伝子発現が低下する機序を明らかにした。一方腎性貧血は、Epoの産生部位であるperitubular capillary endothelial cellの障害のためにEpo産生が低下することがその原因とされていた。しかし、腎不全でもEpo産生能は保たれ貧血の認められない症例も多く存在する。よって腎性貧血の原因は単にEpo産生部位の障害だけでなく酸素センサーの障害あるいはEpo遺伝子の転写因子の調節不均衡もその一因であると考えてきた。最近、腎不全患者血清に著増することが認められたNO合成酵素(Nitric oxide syntase : NOS)拮抗阻害物質であるN-Monomethyl-L-arginine(L-NMMA)を用いて解析を試みた。このL-NMMAをHep3B細胞へ添加するとEpo mRNAおよび蛋白が低下することを認めた。これはL-NMMAがEpoの他の転写因子は介さずに、GATA転写因子の結合活性を亢進させ、GATAの発現レベルが亢進することによりEpoプロモーター活性が低下しEpo遺伝子発現が低下するためであり、腎性貧血におけるL-NMMAの新しい機序を解明した。しかし現在までに明らかとなっているEpo遺伝子のcis-elementはすべて肝でのLiver Inducible Element(LIE)であり産生部位である腎でのKidney Inducible Element(KIE)は未だ解析されていない。そこで、ヒト・マウスEpo遺伝子をphage libraryよりscreeningし現在transgenic mouseの系でKIEを解析中である。

CD2,あるいはLCKの制御領域を利用して,c-MafをT細胞特異的に発現させるための構築を作成し,マウス受精卵に導入して,トランスジェニックマウスを作成した.このマウスにおいて,T細胞サブセットがTh2優位になっていることを示唆する血清学的な解析結果が得られている.また,このマウスは,8-10ヶ月以上の加齢によりリンパ腫を好発することも明らかになった.一方,転写活性化領域を欠失するMaf群転写因子であるMafKをc-Mafに対するドミナントネガティヴな分子として利用し,マウス個体においてc-Mafと同様にT細胞特異的に過剰発現させたところ,このマウスにおいてはT細胞の分化が抑制されるという結果が得られた.今後は,これらのトランスジーンを自己免疫疾患自然発症マウスへ導入して,疾患感受性の変化が起こりえるかを検討する. 2) マウスにおけるc-maf遺伝子破壊実験. ジーンターゲッティングの手法を用いて,マウスにおけるc-maf遺伝子の破壊を行った.c-Maf欠損マウスは,多くが胎生後期で致死であり,レンズの形成異常を示した.T細胞の異常について今後解析を行う予定である.

    本研究では、細胞分化研究における代表的モデル系である血液細胞を用いて、細胞分化を規定する転写因子群とその機能を分子レベルならびに個体レベルで明らかにすることを試みた。その結果、Bachをはじめ、造血系細胞の分化に関わるいくつかの転写因子に関して理解が深まった。また、新しい知見とともに予想外の知見も蓄積されたことから、得られた成果が新しい展開へつながることが期待される。(1)新しいNF-E2関連因子のさらなる検索を行い、新規因子Nrf3を発見した。発現パターンの解析結果から、Nrf3は造血細胞の分化過程で機能する可能性が考えられる。そこで、その機能を個体レベルで理解するために、エンゲル教授と共同でnrf3ノックアウトマウス作成を開始した。(2)Nrf2は造血系細胞の分化過程で重要な役割を担うものと予想された。そこで、ノックアウトマウスを作成し、変異マウスにおける造血系の異常の有無を検討したところ、顕著な変化は認められなかった。しかしながら、予想外なことに、変異マウスでは異物代謝系第二相の酵素遺伝子群の発現誘導が起きないことが明らかになった。すなわち、Nrf2は異物代謝系酵素群のマスター発現調節因子であると考えられる。(3)Bach1の特徴は、クロマチン構造の調節に関わるモチーフBTBドメインを有することである。そこで、BTBドメインの機能を原子間力顕微鏡を用いて解析し、Bach1はシス制御領域間の相互作用を仲介する構造転写因子として機能することを明らかにした。現在、bach1遺伝子を欠損するノックアウトマウスを作成し、解析を進めているところである。

    須田、三浦、金倉は、造血幹細胞におけるいくつかのシグナル伝達機構を明らかにした。幹細胞から、TIE_s、HTK、STK/RONなどの新しい受容体型チロシンキナーゼを幹細胞から、RT-PCR法によりクローニングした。殊に、TIE-1,TIE-2は、血管内皮細胞と同時に、造血幹細胞に発現していた。これらの発見により、血管内皮細胞の前駆細胞であるアンジオブラストから、造血幹細胞が発生してくる過程が解析できるようになった。また、c-Kitの機能獲得型異常により、血液細胞(肥満細胞)や腸管の特殊な細胞(カハール細胞)の自律性増殖が起きることを示した。 中内は、マウス骨髄細胞のCD34^-Kit^+Sca^+LIN^-細胞とCD34^+Kit^+Sca^+LIN^-がそれぞれ、長期および短期の骨髄再建能をもつことを、移植実験で示した。CD34陰性の幹細胞がヒトの造血システムにあることも確認された。ヒト造血幹細胞・前駆細胞を対外で増幅させることは、臨床的応用の面から興味深い。 中畑は、IL-6可溶性受容体とIL-6とSCFの組み合わせにより、ヒト造血前駆細胞が増幅することを示したが、幹細胞の増幅はいまだ成功していない。 浅野は、ヒト造血幹細胞を解析するために、サルの幹細胞移植システムを構築した。 山本は、GATAとMafの分子群が赤血球産生に関与することを、GATA-1遺伝子破壊マウスとGATAプロモーターLacZトランスジェニックマウスを用いて示した。

    血液細胞の分化に関わる種々のシグナルは系列特異的な形質を規定する遺伝子群の発現に集約され、それらの発現を調節する転写因子は血液細胞の分化の鍵を握ると考えられる。赤血球、巨核球系の細胞の分化に働く転写因子を明らかにすることが本研究の目的である。 まず、ヒト白血病由来サイトカイン依存性細胞株にトロンボポエチン(TPO)受容体(MPL)を導入し、TPOにより巨核球系へ分化し、エリスロポエチン(EPO)により赤血球系へ分化するM-TAT/MPL細胞を作成した。それぞれのサイトカインの添加により、GATA-1やNF-E2など赤血球系、巨核球系への分化に必須な転写因子の発現量が変化するか否かを検討したが、M-TAT/MPL細胞はTPO、EPO添加以前よりそれらを発現しており、明らかな発現量の変化は認めなかった。 次に、マウスGATA-2遺伝子の転写調節機構の解析を行った。GATA-2は造血幹細胞に働き、すべての血液細胞に必須の転写因子であるとされている。また、赤血球系、巨核球系の最終分化にはGATA-2の発現が抑制され、同じ配列に結合するGATA-1の発現が優位になることが必要とされている。われわれはこのようなGATA-2の発現の調節が2つのプロモーターと第一エクソンの使い分けによって行われていることを明らかにした。さらに、ヒトとカエルに共通なCCAAT配列を持つIGプロモーターより5kbp上流にあるISプロモーターが、血液細胞と神経細胞におけるGATA-2の発現に特異的に働いていることをRT-PCRおよびトランスジェニックマウスによる解析により明らかにした。また、ISプロモーターの活性を担う部分を同定し、その塩基配列への蛋白質の結合を証明した。

    本研究では造血組織におけるヘム合成の調節機構を主として転写のレベルから解析した。我々は赤血球分化に伴うヘム代謝調節にはNF-E2を始めとする赤血球系転写因子が大きな役割を果たしており、赤血球型δ-アミノレブリン酸合成酵素(ALAS-E)を介したヘム合成が大きな役割を果たしていることを示した(Meguro et al.,1996)。 更にNF-E2を構成する小サブユニット(P18)欠失マウスが致死的であることを示した。一方、ALAS-Eを欠損したES細胞をを分化誘導した場合、GATA-1、NF-E2といった赤血球系転写因子の発現誘導は野生型細胞と異ならなかったが、細胞内のヘム室、ベンチジン陽性細胞、β-メジャーグロビンの発現が極めて減少していることが明らかとなった(Harigae et al.,1998)。従って、ALAS-Eを介したヘム合成はNF-E2の転写活性に影響している(Nagai et al.,1998)ばかりでなく、後期赤血球分化時における成熟型のグロビン合成を正に制御していることが示された。 一方、我々は一般型δ-アミノレブリン酸合成酵素(ALAS-N)の発現がNF_KB認識配列により負に調節されているだけでなく(Fujita,1997)、代表的赤血球系転写因子GATA-1認識配列を介しても負に制御されていることを見い出している。このGATA-1遺伝子の造血型プロモーターを破壊して精巣型プロモーターのみが機能するノックダウンマウスは11.5日で致死的で、胎児期造血では血液細胞は存在するもののヘモグロビン化された細胞が著減しており、これはALAS-E欠損より早期の異常と考えられる。

    来年度から始まる重点領域研究「転写調節機構から挑む高次生命現象の解析」の研究班員の相互理解と研究の方向性を検討するために平成8年12月18日艮陵会館(仙台)に本研究班員及び重点研究班員予定者23名が集まり、各々の研究者のこれまでの研究成果と今後の重点領域研究における研究方針を発表し、相互に意見を交換した。そして、日本の転写の研究に於いて世界の流れから若干遅れていると考えられる基本転写装置に関する研究は半田、大熊、久武、堀越らによって強力に推し進められることの期待できる体制ができた。遺伝子に特異的な転写調節因子についてはその生物作用発現に至る経路についてはコアクチベータ-あるいはコリプレッサーとの相互作用を通して基本転写装置に転写調節シグナルが伝えられる経路か、あるいは基本転写装置のサブユニットとの相互作用を通して直接に伝えられる道筋が考えられる。本研究では特にコアクチベータ-あるいはコリプレッサーの存在についてtwohybrid法等を用いてさらに検討を加える方針である。また各々の転写因子の生物作用についてはトランスジェニックマウスあるいはノックアウトマウスを作成して機能の解析を各々の班員は既に始めている。例えば審良はNF-IL6, STAT, C/EBPのノックアウトをマウスを作製し、脂肪細胞の発生におけるこれら転写因子の関わりを研究しており、藤井はAhリセオウタ-のノックアウトマウスを作製しダイオキシンの催奇形性について研究を進めている。さらに石井はCBPのノックアウトマウスを作製して、その因子の示す多機能性の解析を行っている。また藤井と重点研究における事務局担当予定者の山本とは連絡をとって効率的な班運営と重点的な研究の方向性について意見の交換を行った。

    [研究成果]今年度の研究の成果として以下の点があげられる。 精巣特異的GATA-1プロモーターの機能解析:トランスジェニックマウスの系を用いて、GATA-1遺伝子の精巣特異的な発現に必要なエレメント、さらには周期的な発現に必要なエレメントを同定を試みた。様々なGATA-1の制御領域断片にレポーター遺伝子を結合したトランスジーンを作成し、それらを用いてトランスジェニックマウスを作成した。そのうちの1つのラインで精巣にレポーター遺伝子の発現を認めた。さらに、そのラインでは精巣での周期的な発現も確認された。他のトランスジェニックマウスラインも含めた解析より、精巣特異的な発現および周期的な発現には、精巣特異的な第1エクソンの上流領域だけでは十分でなく、第1エクソンの下流域に必須なエレメントがあることが明らかとなった。 プロモーター特異的なターゲティングマウスの作製:精巣特異的なプロモーターのみで精子形成が支持できるかどうかを知る目的で、血球特異的なプロモーターのターゲティングを行った。GATA-1遺伝子はX染色体上に存在し、通常のES細胞では1コピーのみ存在する。以前報告されたGATA-1完全欠損ES細胞からは生殖細胞キメラが得られなかったが、赤血球特異的プロモーターのみをターゲティングしたES細胞からは生殖細胞キメラが形成され、ターゲティングアレルが効率良く次世代に伝達された。ターゲティングアレルを有するヘテロ雌マウスでは様々な程度の貧血が見られ、雄マウスは著明な貧血のため胎生致死であった。我々のターゲティング法では、生殖細胞キメラが容易に形成されたことより精巣型プロモーター単独で精子形成を支持できることが示唆された。

    本重点領域研究は今年度が最終年度となるので各々の研究班員は一応のまとめをすることを中心に研究を行った。審良はSTAT3遺伝子の欠失マウスを作製したところ、同型接合体で致死になることを見出した。致死は胎生期の極めて初期に観察され、原腸形成にも至らないことが判明した。また転写因子STATの特異性を決める部位がSHドメインと考えられていたが、STAT1とSTAT3のドメインスウィッチの実験からSTAT3のチロシンリン酸化部位よりさらに下流のアミノ酸も特異性の決定に関与していることを明らかにした。石井はCBPがMybのコアクチベータ-であることを明らかにすると共にショウジョウバエのcubitus interruptusのコアクチベータ-としても働き、形態形成の因子として働いていることを明らかにした。半田はカゼインキナーゼ(CKII)が転写制御に関与していることを見出して、その阻害剤DRBの作用点は転写開始前にあるが、その作用効果は転写伸長段階に現れることを見出した。これはRNAポリメラーゼIIの転写伸長活性が転写開始前に既に調節されているという新しい転写制御機構を示したものである。そのDRBの転写阻害に関わる転写制御因子(DSIF)を同定し、分離・精製した。DSIFは160と14kDaのサブユニットからなる複合体で、その部分アミノ酸配列からオリゴヌクレオチドのプライマーを作製して、RT-PCR法によってcDNAの全構造を決定した。その結果DSIFは酵母の転写因子SPT5とSPT4に相当するヒトホモローグであることが判明した。山本はGATA-1の遺伝子破壊マウスの作製に成功し、同型接合体は卵黄嚢造血細胞の成熟障害のため貧血となり胎生致死となることを明らかにした。藤井はダイオキシンなどの薬物誘導に関わるAhリセプター/Arntへテロ2量体のArntの転写活性化ドメインがCBP/P300と相互作用することを示し、この転写活性化系でもCBP/P300がコアクチベータ-として働いていることを明らかにし、さらに東大・医科研・勝木教授との共同研究でAhリセプター破壊マウスを作製し、Ahリセプターがダイオキシン等の催奇形性に関与していることを明らかにした。

    血管新生の代表は炎症と癌である。今回ヒトGATA遺伝子群をとりあげ、そのmRAN発現を炎症性腸疾患と大腸癌組織をもちいてin situハイブリダイゼーション法で調べた。方法は試験管内転写にて合成したディゴキシゲニン標識tRNAを用いる、非放射性法である。固定には4%パラフォルムアルデヒドと0.5%グルタールアルデヒド液を用いて、手術材料を細切して浸漬固定し、パラフィン包理した。その結果、GATA-2,-3において有意の所見をえた。血管新生の代表である癌間質と炎症性腸疾患の潰瘍形成部ではGATA-2,-3は陰性であった。これより血管が強く新生されているところではGATA遺伝子群は発現していないと結論された。潰瘍底の炎症の強いところからすこしはなれ、炎症性細胞浸潤が少なくなった部分では小静脈にGATA-2,-3の発現をみた。また、癌では進行癌の先進部の宿主側において、小静脈に陽性であった。この部分は別の我々の研究において、癌に対する宿主の炎症免疫現象が起こっている場であることを解明しており、これら炎症細胞透過と何らかの関係があるものと推測された。また、潰瘍形成部の浸潤Tリンパ球にも陽性所見を認めた。T細胞の活性化との関連が示唆され、炎詳論への応用が期待される。このほか癌細胞、癌間質線維芽細胞にも陽性所見を認めた。以上の点より、これまでわれわれが行って来た癌における宿主反応と炎症反応との類似がさらに確認されるとともに、癌間質における多様な反応現象に対する転写因子レベルでの制御の解明につながると期待された。

    1.研究背景 がん遺伝子の発見をきっかけに、がん研究は遺伝子の時代に入り、欧米のがん研究先進国を中心に激しい研究競争を繰り広げている。地理的に隔離されているわが国の研究者は、研究者との直接の討論、情報、資料交換に自ら制限があり、ともすると孤立しかねない。この問題点を克服するため、わが国の第一線の研究者を積極的にがん研究先進国に送る必要がある。 本研究は、ヨーロッパのがん研究先進諸国との研究交流を目的に組織された。特に、日独、日仏がんワークショップはそれぞれ一年毎にヨーロッパ本国と日本と場所をかえて行われているが、本年度は両者ともヨーロッパで開催された。本年度は17名をヨーロッパ諸国に派遣した。 2.日仏がんワークショップ 1996年9月17日〜20日、フランス・リ-ル市、パスツール研究所において、「がん宿主相関の分子細胞生物的基盤」をテーマとしてワークショップが開催された。主催者はフランス側がDr.Stehelin、日本側が渋谷正史、豊島久真男であった。わが国からは岡田雅人(阪大・蛋白研)、平井久丸(東大・医)、松本邦弘(名大・理)、渋谷正史(東大・医科研)、宮坂昌之(阪大・医)、黒木登志夫(昭和大・腫瘍分子研)、西川伸一(京大・医)、辻本賀英(阪大・医)、餐場篤(東大・医科研)が本研究費で出席した。なお、若杉尋(国立がんセンター)、広橋説雄(国立ガンセンター・研)、吉倉廣(東大・医)、神田忠仁(国立予研)、豊島久真男(大阪成人病センター)が別途予算により参加した。 プログラムは次の通りであった。Session1:シグナル伝達(日本側3名、フランス側3名発表)、Session2:腫瘍・宿主相関(日本側3名、フランス側3名)、Session3:発生・分化(日本側3名、フランス側3名)、Session4:細胞増殖と抑制(日本側3名、フランス側3名)。 3.日独がんワークショップ 1996年9月26日〜27日ドイツ・ハイデルベルグ市ドイツがんセンターにおいて「ウイルスによるヒトのがん」に関する日独がんワークショップを開催した。主催者はドイツ側がH.zur Hausen、S.Meuer、日本側は吉田光昭であった。わが国から高田賢蔵(北大・医)、永田恭介(東工大・生命理工)、石橋正英(愛知がんセンター・研)、菅村和夫(東北大・医)、園田俊郎(鹿児島大・医)が本研究費班員が研究を行った。さらに吉田光昭(東大・医科研)、伊藤嘉明(京大・ウイルス研)、豊島久真男(大阪成人病センター)、吉倉廣(東大・医)、神田忠仁(国立予研)が別途予算で参加した。 発表テーマは次の通りであった。HTLV(日本側3名)、HIV(ドイツ側2名)、EBV(日本側1名、ドイツ側1名)、HPV(日本側2名、ドイツ側4名)、アデノウイルス(日本側1名)、SV40(日本側1名)、肝炎ウイルス(日本側1名、ドイツ側1名)、ヒト白血病(日本側1名)、がん免疫(日本側1名) 4.その他の派遣者 研究が急速に進展しつつある領域について、野田哲生(癌研)、安本茂(神奈川がんセンター)、富永明(高知医大)、村上義則(国立がんセンター)を派遣した。

    精子形成機構の理解を進める上では,支持細胞であるセルトリ細胞における特異的な遺伝子発現制御機構を理解することが重要である.報告書はさきに,赤血球系転写因子GATA-1が精巣特異的なプロモーターを利用して,精子形成周期と関連してセルトリ細胞で発現していることを明らかにした. 1.セルトリ細胞におけるGATA-1の発現制御の検討:セルトリ細胞におけるGATA-1の発現調節は,免疫染色法とin situ hybridization法によるなど解析から,転写レベルで行われていることが明らかとなった.これまでに広くセルトリ細胞株を検索した結果,GATA-1の発現しているセルトリ由来培養細胞株は見出されなかった.また,セルトリ初代培養細胞系でもGATA-1の発現は認められなかった.さらに,赤血球型と精巣型のそれぞれのプロモーターにルシフェラーゼ遺伝子を結合したレポーター遺伝子より種々の欠落変異体を作成しセルトリ細胞由来培養細胞に遺伝子導入して転写活性の検討を行った.その結果,セルトリ細胞の培養株においては,精巣型プロモーターの転写活性化が特異的に抑制される現象を見出した.また,それぞれのプロモーター/第一エキソンにβ-ガラクトシダーゼをつないだレポーター遺伝子を作成し、それらを用いてトランスジェニックマウスを作成した.赤血球型プロモーターはトランスジェニックマウスで特異的な遺伝子発現を行ったが,調べた範囲では精巣型プロモーターとその上流域は本システムでは不活性であった. 2.GATA-1発現と精子形成との関連性の検討:GATA-1の精子形成サイクル特異的な発現を解析するため,GATA-1発現開始後にその発現が最初にOFFとなる精細管が出現する5週齢前後の精巣を詳細に検討した.その結果,核濃縮期の精子細胞の存在がGATA-1発現の抑制に重要であることが明らかとなった.

GATA因子群やNF-E2を発現するプラスミドを赤血球系形質を持った培養細胞株に遺伝子導入し,これらの因子を誘導的に過剰発現した際の細胞の表現形質や分化能の変化を検討した.NF-E2の小サブユニットであるMafKをマウス赤白血病(MEL)細胞に過剰発現したところ,同細胞は他の誘導剤の存在の有無に関わらず赤血球に分化した.このことから,MafKは実際に血液細胞の分化に働く転写因子であることが理解される.また,GATA因子群のうちGATA-1とGATA-2をコードする遺伝子の転写制御解析を進めた.GATA-1の精巣型プロモーターには二つのGATA配列が存在し,それらは実際に転写活性化シグナルを媒介することができる配列であった.一方、赤血球型プロモーターの機能をトランスジェニックマウス系を用いて検討したところ,同プロモーターと上流域2.9kbはin vivoで胎児型赤血球特異的な転写活性化を指示することが可能であることが明らかになった.さらに,MafK遺伝子の構造と機能を行い,MafK遺伝子には中胚葉特異的なプロモーター/第一エキソンと神経細胞特異的なそれとが存在することを見出した.マウスGATA-1抗体N6はPFA固定した組織切片中のGATA-1を免疫染色できることから,MEL細胞より核を単離し,PFA固定後N6抗体で免疫沈降する方法でGATA-1の標的遺伝子の単離・同定が可能である.そこで,本方法を用いてGATA-1遺伝子の調節領域にGATA-1自身が結合していることを証明した.

    GATA配列に結合する転写因子が遺伝子発現の赤血球特異性規定に重要な貢献をしていることが強く示唆されている.私たちは以前に,GATA因子がファミリーを形成していることを明らかにしたが,本研究において,ヒト白血病由来細胞株について広く調べてみると,GATA-1発現が赤血球・巨核球系の分化形質発現と強く相関するのに対して,GATA-2の発現はさらに未分化な造血細胞にも見られることを見出した.この結果から,GATA-2が造血前駆細胞において重要な機能を果しているのに対して,GATA-1はすでに分化がある程度進んだ細胞での形質発現に貢献していることが示唆される.私たちはまだ精巣型GATA-1の存在を発見したが,本研究において,精巣型および赤血球型プロモーターを含むGATA-1遺伝子のクローン化に成功し,その機能解析を実施した.赤血球型プロモーターに機能的なGATA配列が存在することはすでに知られていたが,本研究から,精巣型プロモーターにもGATA配列が存在し,重要な機能的貢献を果していることが明らかになった.ところで,同様にGATA-3遺伝子の解析を行ったところ,調節領域に存在するGATA配列は機能的に重要ではなかった.このことは,GATA-2とGATA-1の遺伝子の調節様式が異なることを示しており、転写因子それ自身の転写制御を考える上で興味深い.ところで,細胞より核を単離し,PFA固定後にGATA-1抗体N6で免疫沈降する方法で,GATA-1の標的遺伝子の単離・同定を試みた.赤血球系細胞単離核よりGATA-1・DNA複合体を精製してみると,その中にはすでに機能的GATA配列が存在することが知られているGATA-1遺伝子やエリスロポエチン受容体遺伝子の調節領域が濃縮され,細胞内でこれら遺伝子が実際にGATA-1の標的遺伝子となっていることが明らかとなった.

    本研究では、赤血球系転写因子であるNF‐E2 p45の機能が、Maf関連蛋白質との会合によりどのように調節されるのか、並びに、赤血球分化におけるMaf関連蛋白質とp45の機能とその作用機作を明らかにすることを目的とした。本年度は以下の成果をあげた。 1.小Maf群蛋白質のうち、MafKをコードするマウスcDNAを単離した。すでに報告されているニワトリMafKとのアミノ酸配列の比較から、機能上重要と考えられる領域が明らかになった。 2.mafK遺伝子の発現様式の詳細な解析を、正常骨髄細胞とマウス胚を材料に用いて行った。その結果、mafK遺伝子は血球細胞の分化に加え、間葉系細胞と神経細胞の分化にも深く関与することが推察された。 3.MafKとp45のcDNAを培養細胞内で発現させ、転写因子としての機能を解析した。その結果、MafKは単独では転写抑制因子として機能すること、そしてp45それ自体のDNA結合活性は非常に低いことが明らかになった。一方、MafKとp45とのヘテロ二重体(NF‐E2)は強くDNAに結合し、転写を活性化することも明らかになった。さらに、NF‐E2による転写活性化に必須の領域を、p45分子上に同定した。 4.マウス赤白血病細胞株を用いて、mafK遺伝子を亜鉛依存性に過剰発現する細胞株を樹立した。この細胞の解析から、MafKは赤血球の分化を促進することが明らかになった。また、MafKとヘテロ二重体を形成する未知の蛋白質の存在が明らかになった。

    本研究では種々の特色ある細胞分化系を用いて、その機能、局在性の異なるいくつかの癌遺伝子産物の細胞分化決定に果たす役割を分子レベルで解明することを目的としている。まず、核内癌源遺伝子産物としてのc-Mycが転写因子YY-1との結合を介して赤血球分化特異的遺伝子のエンハンサーの制御を行っていることが明らかとなった(帯刀)。また、赤血球特異的転写因子NF-E2がロイシンジッパー構造をもつp45とMaf癌原遺伝子産物の会合体であることを明らかにした(山本、西沢)。さらに、MybのNMRによる構造解析から、MybとNF-IL6との相互作用が示唆された(石井)。さらにPEBP2もα,β両サブユニットの会合により細胞内局在性や機能の調節を行っていることが明らかとなった (丸山)。そしてmyc遺伝子ファミリー(帯刀、北中)、myb遺伝子ファミリー(石井)、maf遺伝子ファミリー(西沢)、relファミリー(井上)の各メンバーが微妙な活性調節機構をもつことにより蛋白間相互作用を介して、多様な転写制御機能を示すことが本研究を通じて明らかとなった。 また細胞膜受容体としてのEpo受容体の活性型K-rasによるシグナル伝達活性制御の解析(井川)、受容体型癌遺伝子c-kitの突然変異体の詳細な解析(北村)から、受容体の構造と機能の理解に進展がみられた。さらに、血液細胞分化に伴うcdc2発現制御のE2Fによる制御機能が明らかとなり(大田)、癌遺伝子産物による細胞増殖分化の決定における機能の上から重要な接点ができたと思われる。

    私たちは以前にGATA因子がファミリーを形成していることを明らかにしたが,本研究ではGATA‐1発現が赤血球・巨核球系の分化形質と強く相関するのに対して,GATA‐2発現はさらに未分化な造血細胞にみられることを見出した.この結果は,GATA‐2が造血前駆細胞において機能しているのに対して,GATA‐1はすでに分化がある程度進んだ細胞での形質発現に貢献していることを示唆しており,転写因子群の機能分担を考察するうえで興味深い. NF‐E2を構成する一つのサブユニットであるp45のcDNAクローン化が最近報告され,p45は塩基性領域/ロイシンジッパー構造を持っており,もう一つのサブユニット(p18)とヘテロ二量体を形成してNF‐E2活性を示すことが提唱された.私たちは西澤誠博士と協力して,p18の本体は核内癌遺伝子Mafの関連遺伝子である小Maf群蛋白質であることを発見した.小Mafホモ二量体はNF‐E2配列を介して負の転写抑制を行うのに対して,P45が同時に細胞内に存在してヘテロ二量体を形成するとその分子は同じ配列を通して転写活性化に働く.NF‐E2配列を通して転写活性化と抑制はMafとp45との濃度平衡の変化に応じて行われており,このことから新しい転写制御様式が存在することが強く示唆される.最近,p45はショウジョウバエCNC因子と相同性を持った因子からなるファミリーを構成していることが明らかにされた.このことからNF‐E2は異なるサブユニットの解離・会合を通して多様な遺伝子発現制御を創り出してしることが理解される.造血幹細胞は多様な細胞系列へ分化するが,それぞれの細胞系列の確立の際に転写因子群が重要な貢献をしていることは疑いない.私たちは赤血球特異的な遺伝子発現調節機構の解析を通して血液細胞分化過程の理解を試みているが,それはまた細胞分化機構一般の分子的基盤の理解を進めるものであると思われる.

    1. 先天性ヘム代謝異常の分子生物学的解析:(1)遺伝性コプロポルフィリン症(HCP)の解析-HCP患者のコプロポルフィリノーゲンオキシダーゼの一方の対立遺伝ではGly^<172>がHisへと置換しており、もう一方の対立遺伝子ではGly^<89>SerへVal^<194>がIleへと置換していいた。患者の二人の姉妹の一方からは後者のアミノ酸置換が検出された。これらの3種類の置換をもつ3種類のcDNAの発現実験を行なった所、His^<172>が存在する場合のみ活性が全くないことが判明した。Gly^<172>は大腸菌からヒトの本酵素まで保存されており、蛋白質の構造上重要な役割を担っていると考えられる(Hum.Mol.Genet.(1994)3:1807-1810)。 (2)肝性骨髄性ポルフィリン症(HEP)の解析-HEP患者のウロポルフィリノーゲンデカルボキシラーゼの一方の対立遺伝子からはT^<417>G^<418>T^<419>からCCAへという突然変異が、他方の対立遺伝子からはA^<677>からCへと突然変異が検出された。発現実験の結果、前者を有するcDNAからは80%の活性をもつ酵素が、後者においては40%の活性をもつ酵素が転写・翻訳されることが示された(J.Inbest.Dermatol.(1994)93:128-134)。 (3)これらのほか、遺伝性鉄芽球性貧血・異型性ポルフィリン症・δ-アミノレブリン酸脱水酵素欠損による肝性ポルフィリン症のそれぞれの遺伝子異常の解析を進めており、既にいくつかの異常の存在を突き止めている。 2. ヘム代謝調節機構の研究:上記の研究と平行して、先天性ヘム代謝異常症の発症に関連すると考えられるヘム代謝調節に関する基礎的な研究を行なっている。例えばヘム合成系の終末酵素であるフェロキラターゼ(FeC)mRNAの寿命は十分なヘムが供給されないときに著明に短縮しており、このことがFeCの先天異常である骨髄性プロトポルフィリン症の発症あるいは遺伝性鉄芽球性貧血時のFeC活性の低下に関与していると考えられる(Brit.J.Haematol.(1993)83;485-490;ibid(1993)84:670-675;J.Bioenerg.Biomembr.(1995)in press)。 また、今まで明らかではなかった赤血球系におけるヘム代謝調節が、ヘム代謝異常に及ぼす影響を明らかにするために、赤血球系転写因子とヘム代謝調節の関係を解析することにした。その結果、代表的な赤血球系転写因子の一つであるGATA-1が精巣で精巣特異的なプロモーターを利用して発現していることを明らかにした(Nature(1993)362:466-468)。さらに、他の赤血球系転写因子であるNF-E2には従来知られている大サブユニット(p45)の他に小サブユニット(p18)が必要であることを示した(Nature(1994)367:568-572)。そのうえ、赤血球型δ-アミノレブリン酸合成酵素(ALAS-E)を欠損した赤血球系細胞株でヘムの供給が減少するばかりでなく(Blood(1994)83:1662-1667)、NF-E2の大サブユニットの発現が抑制されることを明らかにした。ALAS-Eの先天性の異常により遺伝性鉄芽球性貧血が発症する事が知られているので、今回の発見はその病態にNF-E2が関与することを示唆しており非常に興味深い。 さらに我々は、赤血球ともっとも近縁の細胞である巨核球におけるヘム代謝あるいは、巨核球分化と赤血球分化における赤血球系転写因子の役割等を明らかにするために巨核球系細胞UT-7の巨核球への分化過程・赤血球への分化過程の解析を進めている(Cancer Res.(1993)53:1156-1161;Blood(1993)82:456-464)。今後、ヘム代謝異常の機構を単に突然変異のレベルからだけではなく代謝調節という面から明らかにして行くうえでこれらの研究成果は重要な意味をもってくると考えられる。

    1)食道癌細胞株における細胞増殖因子のmRNAの発現 当科の食道癌細胞株よりmRNAを精製し、主にPCR法により細胞増殖因子の発現を検討した。 a)FGFファミリー:aFGF、bFGF、int-2、hst-1、FGF5 これらのうちaFGF、bFGFの発現は認められたが、int-2、hst-1、FGF5の発現は認められなかった。aFGFとbFGFのNorthern Blottingを試みているが、うまくバンドが出せず、現在検討中である。 b)EGFに関連したもの:amphiregulin、(EGF、TGFα、cript) PCR法によりamphiregulinの発現が確認されたので、Northern Blottingによる検討を考えProbeの作製中である。なおEGF、TGFα、criptに関する食道癌細胞株でのNorthern Blottingによる検討は既になされている。TGFαはすべての細胞株で、EGFは一部の細胞株で発現し、criptの発現は認められていない。 c)その他:Midkine 最近、増殖・分化因子としてMidkineが発見されたが、これが癌化にともなって発現してくると報告されている。Midkineに関してPCR法で検討したところ、食道癌細胞株に発現が認められた。これに関してはNorthern Blottingによる検討を考え、Probeの作製中である。 2)細胞増殖因子に関連して臨床例での検討 hst-1に関しては、mRNAの発現はないものの、遺伝子の増幅が認められ、臨床例で検討した。食道癌切除例50例のうち増幅の認められた症例は、15例(30%)であった。hst-1遺伝子の増幅していた症例には、高分化型扁平上皮癌が有意に多かったが、その他の予後因子との相関は認められなかった。EGFのレセプターであるEGFRに関しても、食道癌での増幅が認められた。EGFR遺伝子の増幅は、45例中11例(24%)に認められたが、予後因子との相関は認められなかった。

    本研究の目的は、動物各組織・細胞におけるGATA転写因子群の発現の様子を検討して、GATA転写因子の機能を理解すること、また、GATA因子の遺伝子構造を検討し、その発現に対して行なわれている調節機序を解明することにある。この目的を達成するために、本研究では1)GATA-1因子の血球系および精巣における分化段階特異的な発現の解析、及び2)各種のGATA因子をコードする遺伝子のクローン化と構造解析を実施した。前者に関して、数種のGATA因子に対する単クローン性抗体を作成することに成功したので、これらの抗体を用いて種々の発達段階の血球系および精巣細胞におけるGATA因子発現の様子を検討した。マウスGATA-1因子に特異的なN6抗体を用いて実施した免疫組織染色では、マウス脾臓および骨髄で赤芽球と思われる細胞の他に、特に巨核球核が陽性に染色されていた。また、GATA-1は精巣のセルトリ細胞に、精巣の発達時期および精子成熟サイクルに特有のパターンを示して発現していることを見出した。一方、GATA-2は巨核球、肥満細胞に加えて、未分化血液前駆細胞に発現していた。後者について、マウス遺伝子ライブラリーより精巣型および赤血球型プロモーターを含むGATA-1遺伝子クローンを得て、それらの詳細な構造解析を実施した。その結果、すでに赤血球型プロモーターの上流に機能的に重要なGATA配列の存在が報告されているが、精巣型プロモーターにもGATA配列が存在していることが明らかになった。そこで、その機能を詳細に解析する目的で、セルトリ細胞の一次培養系調製法を確立した。GATA-2やGATA-3遺伝子の構造を詳細に決定したところ、これらGATA群をコードする遺伝子の構成は各因子間で、また、種を越えてたいへんよく保存されていることを見出した。これらの研究を通して、GATA転写因子群が細胞・組織特異的な転写調節に機能していること、また、その発現が巧妙に調節されている様子がさらに明らかになった。

    5-アミノレブリン酸合成酵素(ALAS)異常と関連があるとされる鉄芽球性貧血とフェロキラターゼ異常が原因とされる骨髄性プロトポルフィリン症について、、病因解明と治療法の開発に資することを目的として、遺伝子レベルでの病態解析を行なった。先ず赤血球型(ALAS-E)と非特異型(ALAS-N)のALASイソ酵素およびフェロキラターゼの遺伝子について生化学的、分子・細胞生物学的研究を進め、これによって得られた様々な知見に基づき、これら酵素遺伝子異常の解析を行った。その結果、以下の様な日本人患者についての最初の成果が得られた。 1)骨髄性プロトポルフィリン症におけるフェロキラターゼ遺伝子変異の解析:昨年度までに、米国白人1例、次いで日本人2例につき、EBウイルスで株化したリンパ球を材料としてフェロキラターゼ遺伝子変異を解析し、第1例については既に報告した。本年度は、前年よりの日本人症例の解析をさらに進め、本酵素遺伝子の変異を確認した。即ち、第1例ではイントロン9、第2例ではイントロン7の5'端(供与部位)の塩基にG→A変異があり、異常スプライシングにより、それぞれエキソン9、エキソン7が欠失したmRNAが作られていた。 2)鉄芽球性貧血におけるALA合成酵素異常の解析:前年度に引続き、日本人X-染色体連関性鉄芽球性貧血患者)1例のEBウイルス株化リンパ球を材料として、ALAS-E遺伝子の変異を検索した。即ち、ALAS-E遺伝子の各エキソン附近をPCR法により増幅し、解析を行ったところ、第5エキソン内に点変異A→T(Asp→Val)が見出された。しかし、本点変異を持つALASを大腸菌に発現させ、同様に発現させた正常ALASと酵素活性を比較したところ、著しい差異はないように思われた。ピリドキサールリン酸結合部位付近や各エキソン-イントロン境界領域等には変異は検出されなかったことから、5'調節領域の異常の可能性を含め、今後さらには幅広い解析が必要である。

    細胞分化の決定における癌遺伝子の役割について、特徴ある細胞分化系において、癌遺伝子産物が細胞分化の制御にどのように関与するかの分子機構を解析した。まず、c-MycやIdなどHLHモチーフをもつ転写制御因子が血球分化の決定に負の因子として働くことを示し、これらと直接相互作用をする因子の遺伝子クローニングを行い、MIDA1と呼ぶ遺伝子を得た。MIDA1は分化の決定時にその発現が転換し、増殖の正の制御因子として働くことを示した(帯刀)。c-Mybと直接結合して負の調節をする因子Lassinをクローニングし、これが増殖の制御をすることを示した(石井)。赤血球分化の特異的転写因子であるNF-E2は、45kd蛋白とmaf癌遺伝子産物とが会合して配列特異的にDNAに結合して転写の制御を行うことを明らかにした。また、同じく赤血球特異的転写因子であるGATA-1の造血幹細胞から分化する際の発現のパターンを解析した(山本)。胚性幹(ES)細胞からin vitroで造血細胞へ分化誘導できる系の開発を行い、多分化能をもち、赤血球へと分化誘導可能な細胞株を樹立した(井川)。白斑,貧血,不妊などの症状を示す変異マウスの原因遺伝子であるc-kit(受容体型癌遺伝子)とそのリガンドであるSlの変異を遺伝子レベルで詳しく解析し、多様な変異のパターンがあることを示した(北村)。

    本研究では,GATA転写因子群の細胞分化への関わり知る目的で,GATA転写因子群の発現をRNAレベルおよび蛋白質レベルで検討し,また,それらをコードする遺伝子の構造解析を実施した.ヒト白血病由来細胞株におけるGATA転写因子群の発現の検討から,GATA-1の存在は赤血球系の分化形質発現にとって重要であること,一方,GATA-2はGATA-1の発現している細胞よりもさらに幼若な骨髄球系細胞に発現し機能していることが示唆された.種々の遺伝子調節領域に存在するGATA配列に実際に結合しているGATA因子分子種を同定する目的で,マウス赤白血病細胞核よりGATA-1/DNA複合体を抗GATA-1抗体を用いて免疫沈降し,得られた画分を抽出して調べて見ると,その中には赤血球特異的に発現している遺伝子群は存在するものの,赤血球で発現していない遺伝子は見い出されなかった.すなわち,GATA配列の中でもGATA-1因子の結合する配列は細胞によって限定されており,このことから逆に,GATA-1因子の結合がこれら赤血球系の遺伝子発現に重要な貢献をしていることが示唆される.新たに精巣におけるGATA因子の発現を見い出した.この因子の一次構造はGATA-1とまったく同一であったが,その発現には赤血球型と明らかに異なる精巣特異的なプロモーターを利用していた.ヒトGATA-2,およびGATA-3遺伝子の構造を詳細に決定したところ,これらGATA因子群をコードする遺伝子の構成は各因子間で,また,種を超えてたいへんよく保存されていた.これらの研究を通して,GATA転写因子群が細胞・組織特異的な転写調節に機能していること,また,その発現に対して複雑かつ巧妙な調節が行われることが理解された.

    動物におけるヘム生合成系の調節酵素として機能しているδ-アミノレブリン酸合成酵素には、赤血球系列で特異的に発現し、ヘモグロビンへのヘム供給に働く赤血球型酵素(ALAS-E)と、広く一般の組織で発現している非特異型酵素(ALAS-N)の、2種のイソ酵素が存在する.本研究では、本酵素の特に転写レベルに働く調節の分子機序を解明する目的で、ラットALAS-N遺伝子の構造解析を中心に研究を進め、いくつかの興味深い知見を得た。[1]ラットALAS-Nの遺伝子は約14kbの長さで、11個のエキソンより成り、遺伝子座はゲノムに1か所と推定された。10エキソンより成るニワトリALAS-Nでは翻訳開始点が第1エキソンにあるのに対し、ラットALAS-Nでは第2エキソンにあり、その約1kb上流に83bpの第1エキソンが確認された。一方、ラットの第3〜11エキソンはニワトリの第2〜第10エキソンによく対応していた。また、ALAS-N転写開始点は翻訳開始コドン上流103bpにあり、第1エキソンには多くのCpG配列が見られたが、ALAS-Eに見られるIRE様構造は存在しなかった。5'上流域約1.5kbの解析では、プロモーター領域にTATAボックス、CACCCモチーフ、NRF結合配列、さらに上流にNF-κB結合配列、CAATTモチーフ、熱ショック要素、GATA配列などが認められた。[2]ALAS-E(ヒト)についても比較したところ、その5'調節領域は他の赤血球系特異的に発現する遺伝子に共通なシス要素を含み、機能解析の結果GATA配列の重要性が示唆された。[3]予備的実験から、ラット肝癌由来H4-II-E細胞では、ヘム合成を抑制した場合、デキサメサゾンを同時添加するとALAS-NmRNAが増量すること、また、ハーダー腺では、ALAS-Nだけでなく、フェロキラターゼ以外の他のヘム生合成系諸酵素のmRNAレベルも高く、ヘム生合成系全体の発現調節が肝とは異なる状況にあると考えられること等本酵素転写調節機序を解明するための重要な手掛りが得られた。

    遺伝的ヘム生合成異常のなかで、5-アミノレブリン酸合成酵素(ALAS)異常が指摘されている鉄芽球性貧血とフェロキラターゼ欠損が原因とされる骨髄性プロトポルフィリン症(EPP)について、遺伝子レベルでの解析を試みた。その結果、昨年度までにヒト両酵素遺伝子の構成や5'調節領域の構造を解明し、EPPの一例(米国白人)についてフェロキラターゼ遺伝子変異を同定したのに続き、本年度には、次のような知見を得た。 1.日本人EPP最初の解析例として、EBウイルスで株化した患者リンパ球を材料にフェロキラターゼ遺伝子の変異を調べた。その結果、第1例ではイントロン9、第2例ではイントロン7の5'端の塩基にG→A変異があり、異常スプライシングにより、それぞれエキソン9、エキソン7が欠失したmRNAが作られていることが知られた。なお、第2例では、エキソン7内にアミノ酸置換を与えないの塩基変異G→Cが1箇所見出された。 2.赤血球型ALAS(ALAS-E)遺伝子の機能解析:1)赤血球系細胞における遺伝子発現調節に重要なシス因子群を含むALAS-E遺伝子5'調節領域の機能をCAT assay法により解析したところ、赤血球特異的遺伝子発現には上流側のGATA配列の寄与が特に大きいことが示唆された、2)白血病細胞株を用いた実験により、赤血球への分化にはALAS-Eの誘導を介したヘムの供給が重要であることが明らかにされた。 3.日本人鉄芽球性貧血におけるALAS-E遺伝子解析の第1例として、X-染色体連関性鉄芽球性貧血患者(ビタミンB_6不応性)について、EBウイルス株化リンパ球を材料にALAS-E遺伝子の変異を調べたが、B_6応答性症例について最近米国で報告されたようなピリドキサールリン酸結合部位付近の異常などは検出されなかった。5'調節領域の異常の可能性を含め、今後さらに解析を進める予定である。

    ヘム生合成経路でそれぞれ最初と最後に位置し、ヘム生合成調節のうえで最も重要な役割を果している5ーアミノレブリン酸合成酵素(ALAS)とフェロキラタ-ゼ(FC)の遺伝的異常による病態について、特に、i)鉄芽球性貧血におけるALAS異常の病態への関与、並びにii)骨髄性プロトポルフィリン症(EPP)におけるフェロキラタ-ゼ異常の実体を分子レベルで解明することを目的とした研究計画を実施し、次ぎのような成果を得た。 1)鉄芽球性貧血およびEPPにおける遺伝子上の変異解明の基礎として、ヒト遺伝子ライブラリ-より赤血球型ALAS(ALAS‐E)およびFCの遺伝子クロ-ンを単離し、その構造解析を行い、FC遺伝子のイントロンーエクソン境界の全て、ALAS‐Eについてはその一部の塩基配列を決定した。さらに、5'‐調節領域の解析を行った結果、ALAS‐Eでは、GATA‐1やAP‐1の結合配列、CACCC配列、CCAAT配列などの赤血球系細胞での遺伝子発現調節に重要なシス因子群の存在が知られた。FCでも同様の配列が見られたが、CCAAT配列は存在しなかった。なお、両酵素遺伝子には典型的なTATAA配列は見られない。また、フェロキラタ-ゼ遺伝子の局在部位は第18染色体であると同定された。 2)EPPにおけるFC遺伝子変異の解析のため、本症患者1例(米国白人)のEBウイルスで株化したリンパ球を材料として、FCmRNAの細胞内レベルや転写速度、cDNAや遺伝子DNAの構造などを解析した。その結果、異常対立遺伝子の第1イントロンのアクセプタ-部位の1塩基置換(C→T)があり、これに起因するスプライシングの異常により、作られるmRNA.から第2エクソン部分が欠失していることが伴明した。 今後、以上の成果に基づき、鉄芽球性貧血でのALAS‐E異常や本邦EPP症例におけるFC遺伝子の変異などの解析をさらに進める予定である。

    私たちは以前に、ニワトリのGATA‐2およびGATA‐3因子のcDNAをクロ-ン化し、その構造を報告した。これら因子のニワトリ各組織・細胞における発現を調ベてみると、GATA‐3因子mRNAは主としてTリンパ球と脳にその発現がみられた。GATA‐3因子の発現様式が動物系に一般的に観察される現象なのか否かを知る目的で、次いでヒトおよびマウスのGATA‐3因子のcDNAクロ-ン化に取り組んだ。両種のTリンパ球由来のcDNAライブラリ-をニワトリGATA‐3因子のcDNAをプロ-ブにしてスクリ-ニングしたところ、タンパク質全長をコ-ドするcDNaクロ-ンが得られ、その解析の結界、GATA‐3因子の構造は種を越えてたいへんよく保存されていること、またその発現パタ-ンもTリンパ球および神経細胞を中心にしている点で共通していることが明らかになった。過去のデ-タの検索からTリンパ球におけるGATA‐3因子の標的遺伝子の候補として、各種のT細胞受容体(TCR)遺伝子を見出したので、TCRδ遺伝子のエンハンサ-領域に見出されたGATA配列をモデルとして取りあげ、GATA‐3因子がこのcis‐acting elementを介してin vivoで実際に転写活性化する能力があることを実証した(MCB 11,2778ー2784,(1991))。 ヒトおよびニワトリのGATA‐3遺伝子のクロ-ン化および構造解析に着手し、現在その解析を進めている。当初、それぞれのcDNAクロ-ンの最も5'側の約500bpを用いてスクリ-ニングを行なったのであるが、その過程で目的のGATA‐3遺伝子コ-ドするクロ-ンの他に、それの約1/10程度の強さのシグナルを与えるクロ-ン群が両種の場合ともに単離されてきた。その後の解析の結果、これらはいずれの場合もGATA‐2因子の遺伝子であることが判明したので、これらについても現在解析中である。GATA‐3因子遺伝子の場合のもっとも5'側には非翻訳領域をコ-ドする小型のエクソンが存在することがこれまでに明らかになっている。

    1.グリシン開裂系構成酵素をコードする遺伝子の発現が協調的に調節されているかどうかを知る目的で研究した。このためには、本酵素系は4種の構成酵素から成るので、少なくともこの中の2種の蛋白をコードするcDNAをまずクローン化しなければならない。そこで、我々はまず、本酵素系が触媒する反応の最初の段階に必要なグリシン脱炭酸酵素とH蛋白のそれぞれをコードするcDNAをクローン化した。 Hー蛋白cDNAは840塩基長であり翻訳開始メチオニンから164アミノ酸より成るHー蛋白前駆体をコードしており、これに続いて約300塩基の非翻訳領域をコードしていた。一方、グリシン脱炭酸酵素cDNAは3514塩基長であった。翻訳開始メチオニンコドンはcDNA中に含まれていなかったが、遺伝子をクローン化して解析すると、cDNAの5'末端から24塩基上流にそのメチオニンコドンが発見された。グリシン脱炭酸酵素前駆体は1004アミノ酸から成る分子量約12万の大きなサブユニットであった。 3.この2種のcDNAをプローブとして、35:11:1の割合で本系活性を示す肝腎、脳での両遺伝子の転写、両mRNAの存在量を調べた。その結果、これらの臓器ではグリシン脱炭酸酵素遺伝子とHー蛋白遺伝子は1:2の比率で転写されるが、転写量は比酵素活性の違いを反映していた。また、両mRNA量はどの臓器でも等モルずつ存在していたが、それらの絶対量はやはり、比酵素活性の比率と等しい割合で各臓器に分布していた。これらの結果は、グリシン開裂系構成酵素遺伝子の発現は協調的に起こるよう調節されていることを示す。 4.しかし、心筋、脾など本系活性を示さない臓器では、グリシン脱炭酸酵素遺伝子だけが発現しておらず、本系構成酵素遺伝子は臓器により、ある時は協調的に、或は非協調的に発現される。

    酸素および親電子性分子と総称される一群の毒性化学物質は空気・食物などから体内に取り込まれ、癌、動脈硬化、糖尿病などの原因となる。一方、動物細胞は酸素毒性や親電子性分子を感知する仕組み備えており、細胞内に活性酸素や親電子性分子が出現すると、抗酸化応答系や解毒代謝酵素群が働き、これらのストレスは速やかに消去される。このような適応・応答機構の存在は以前から知られていた。しかし、細胞がどのように酸化ストレスや親電子性分子を感知し、それらに対抗する生体防御遺伝子群の誘導・活性化をしているかは長年の謎であった。代表者らは、Keap1が分子センサーとして親電子性分子や酸化ストレスを感知し、転写因子Nrf2を活性化することで生体防御酵素群の発現を制御していることを発見した。本研究では、生体防御センシングの中核をなすKeap1-Nrf2による酸化ストレス感知とNrf2-MafによるDNA配列認識と転写活性化の分子機構を構造生物学(X線、電子線単粒子解析)と細胞生物学の手法を駆使して解明する。
