    Abstract We developed a label-free method for visualizing intracellular temperature distribution using Raman image analysis combined with deep learning. Analysis of the entire region of the O-H stretching band of water using deep learning achieves an accuracy of ∼0.2 °C, allowing intracellular temperature mapping without any pretreatments such as fluorescent labeling. Experiments using photoexcitation of carbon nanotubes attached to living cells demonstrate that this method can obtain transient changes in the temperature distribution within a cell.

    Abstract Supersulphides are inorganic and organic sulphides with sulphur catenation with diverse physiological functions. Their synthesis is mainly mediated by mitochondrial cysteinyl-tRNA synthetase (CARS2) that functions as a principal cysteine persulphide synthase (CPERS). Here, we identify protective functions of supersulphides in viral airway infections (influenza and COVID-19), in aged lungs and in chronic lung diseases, including chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF). We develop a method for breath supersulphur-omics and demonstrate that levels of exhaled supersulphides increase in people with COVID-19 infection and in a hamster model of SARS-CoV-2 infection. Lung damage and subsequent lethality that result from oxidative stress and inflammation in mouse models of COPD, IPF, and ageing were mitigated by endogenous supersulphides production by CARS2/CPERS or exogenous administration of the supersulphide donor glutathione trisulphide. We revealed a protective role of supersulphides in airways with various viral or chronic insults and demonstrated the potential of targeting supersulphides in lung disease.

    ABSTRACT Liquid droplets formed via intracellular Liquid–liquid phase separation (LLPS) are called membraneless organelles and provide enzymatic reaction fields for maintaining cellular homeostasis, while they can be sources of protein aggregates and fibrils, causing neurodegenerative diseases. To understand the nature of intracellular liquid droplets, it is essential to quantify liquid droplets inside a living cell. Here, we performed near-IR fluorescence and Raman imaging to quantify chemical components inside stress granules (SGs) formed via LLPS in living cells under oxidative stress. The Raman images of stressed cells indicate the concentration of nucleic acids in the SGs was 20% higher than surrounding cytoplasm, while the lipid concentration was lower. The intensity of biomolecular C–H bands relative to the water band shows the net concentration of biomolecules was almost the same inside and outside the SGs, indicating intracellular droplets are not highly condensed, but the crowding environments are similar to the surroundings.

    Abstract Liquid–liquid phase separation is a phenomenon that features the formation of liquid droplets containing concentrated solutes. The droplets of neurodegeneration-associated proteins are prone to generate aggregates and cause diseases. To uncover the aggregation process from the droplets, it is necessary to analyze the protein structure with keeping the droplet state in a label-free manner, but there was no suitable method. In this study, we observed the structural changes of ataxin-3, a protein associated with Machado–Joseph disease, inside the droplets, using autofluorescence lifetime microscopy. Each droplet showed autofluorescence due to tryptophan (Trp) residues, and its lifetime increased with time, reflecting structural changes toward aggregation. We used Trp mutants to reveal the structural changes around each Trp and showed that the structural change consists of several steps on different timescales. We demonstrated that the present method visualizes the protein dynamics inside a droplet in a label-free manner. Further investigations revealed that the aggregate structure formed in the droplets differs from that formed in dispersed solutions and that a polyglutamine repeat extension in ataxin-3 hardly modulates the aggregation dynamics in the droplets. These findings highlight that the droplet environment facilitates unique protein dynamics different from those in solutions.

    Abstract Copper-zinc superoxide dismutase (SOD1) has been proposed as one of the causative proteins of amyotrophic lateral sclerosis (ALS). The accumulation of non-native conformers, oligomers, and aggregates of SOD1 in motor neurons is considered responsible for this disease. However, it remains unclear which specific feature of these species induces the onset of ALS. In this study, we showed that disulfide-linked oligomers of denatured SOD1 exhibit pro-oxidant activity. Substituting all the cysteine residues in the free thiol state with serine resulted in the loss of both the propensity to oligomerize and the increase in pro-oxidant activity after denaturation. In contrast, these cysteine mutants oligomerized and acquired the pro-oxidant activity after denaturation in the presence of a reductant that cleaves the intramolecular disulfide bond. These results indicate that one of the toxicities of SOD1 oligomers is the pro-oxidant activity induced by scrambling of the disulfide bonds. Small oligomers such as dimers and trimers exhibit stronger pro-oxidant activity than large oligomers and aggregates, consistent with the trend of the cytotoxicity of oligomers and aggregates reported in previous studies. We propose that the cleavage of the intramolecular disulfide bond accompanied by the oligomerization reduces the substrate specificity of SOD1, leading to the non-native enzymatic activity.

    Liquid-liquid phase separation (LLPS) is an important phenomenon in biology, and it is desirable to develop quantitative methods to analyze protein droplets generated by LLPS. This study quantified the change in protein concentration in a droplet in label-free and single-droplet conditions using Raman imaging and the Raman band of water as an intensity standard. Small changes in the protein concentration with variations in pH and salt concentration were observed, and it was shown that the concentration in the droplet decreases as the conditions become less favorable for droplet formation. The effect of exposure to 1,6-hexanediol was also examined, and this additive was found to decrease the protein concentration in the droplet. A model can be proposed in which the addition of 1,6-hexanediol reduces the protein concentration in the droplet, and the droplet disappears when the concentration falls below a certain threshold value.

    Cu, Zn superoxide dismutase (SOD1) is a representative antioxidant enzyme that catalyzes dismutation of reactive oxygen species in cells. However, (E,E)-SOD1 mutants in which both copper and zinc ions were deleted exhibit pro-oxidant activity, contrary to their antioxidant nature, at physiological temperatures, following denaturation and subsequent recombination of Cu2+. This oxidative property is likely related to the pathogenesis of amyotrophic lateral sclerosis (ALS); however, the mechanism by which Cu2+ re-binds to the denatured (E,E)-SOD1 has not been elucidated, since the concentration of free copper ions in cells is almost zero. In this study, we prepared the (Cu,E) form in which only a zinc ion was deleted using ALS-linked mutant H43R (His43→Arg) and found that (Cu,E)-H43R showed an increase in the pro-oxidant activity even at physiological temperature. The increase in the pro-oxidant activity of (Cu,E)-H43R was also observed in solution mimicking intracellular environment and at high temperature. These results suggest that the zinc-deficient (Cu,E) form can contribute to oxidative stress in cells, and that the formation of (E,E)-SOD1 together with the subsequent Cu2+ rebinding is not necessary for the acquisition of the pro-oxidant activity.

    The denatured Cu, Zn superoxide dismutase (SOD1) has the pro-oxidant activity that is suggested to be related with the pathogenesis of amyotrophic lateral sclerosis (ALS). We showed from the changes in the coordinated metal ions that the Cu ion in the Cu-binding site is the catalytic site of the pro-oxidant activity, and a redox-active metal ion in the Zn-binding site has the auxiliary function to enhance the pro-oxidant activity. The auxiliary function is suggested to arise from the intramolecular electron transfer between the coordinated metal ions in the denatured SOD1. The oxidation/reduction cycle of Cu in the Cu-binding site is assisted with changing the oxidation state of a metal ion in the Zn-binding site. The magnitude of the toxicity of the denatured SOD1 is discussed based on the ability of the auxiliary function.

    Disulfide bonds play a fundamental role in controlling the tertiary structure of proteins; the formation or cleavage of some disulfide bonds can switch the structures and/or functions of proteins. Human galectin-1 (hGal-1), which is a lectin protein, exemplifies how both structure and function are changed by disulfide bonds; the structure and sugar-binding ability of hGal-1 are altered by the formation and cleavage of its three intra-molecular disulfide bonds. In the present study, the dynamics of the structural change of hGal-1 by the formation of disulfide bonds were investigated by time-resolved FTIR spectroscopy combined with a modification in which its thiol groups (-SH) were replaced with S-nitrosylated groups (SNO). Photodissociation of NO from SNO in reduced hGal-1 induced disulfide bond formation and transformed it into the oxidised form. The structural change to the oxidised form involved three distinct kinetics with fast (<300 s), middle (∼600 s), and slow (∼6400 s) lifetimes. In an examination of hGal-1 in the lactose-bound form, structural changes owing to the release of substrate lactose were also observed upon disulfide bond formation. The present method using the photodissociation of NO is useful for monitoring the dynamics of structural changes following disulfide formation.

    We have constructed a fluorescence lifetime imaging (FLIM) system to study the photo-induced dynamics of living cells. The output from a femtosecond mode-locked Ti: sapphire laser is frequency-doubled and focused onto the sample with an objective lens of a confocal microscope. The fluorescence decay of the sample is measured at each pixel of a scanning image. Each fluorescence lifetime is evaluated quickly using time-gating electronics, and the fluorescence lifetime image can be obtained within several minutes. We have combined the FLIM system with a picosecond time-correlated single-photon counting system in which a microchannel-plate photomultiplier is used for detection, so that the value of the fluorescence lifetime at a position can be analyzed quantitatively. A high contrast light-scattering image of a polymer film is also found to be obtained with the FLIM system.

    2024年度から稼働した放射光施設ナノテラスでは、高エネルギー分解能を備えた軟X線・テンダーX線ビームを発生できることから、生体分子の構造解析が可能なX線吸収分光装置の整備が求められている。生体分子では溶液中においてその機能を発現するものが多く、その反応機構を明らかにするには、溶液中の試料を「あるがままの状態」で構造解析する技術が必要である。X線吸収微細構造(XAFS)分光はこの目的に適した手法であるが、XAFS分光では化学結合に関与しない内殻電子励起を利用するため、結合長の微妙な変化には鈍感である。一方、同じく溶液中生体分子観察に利用されるラマン分光は、結合長の僅かな変化を反映してスペクトルが変化するので、反応に伴う微妙な構造変化を検出できる。そこで本課題ではXAFS分光とラマン分光の特長を相補的に利用したテンダーX線XAFS+ラマン同時計測装置を製作し、特に複数の硫黄原子が連結した polysulfide-(S)n-を含む生体分子(超硫黄分子やSOD1タンパク質など)を対象とした構造解析法を開発し、ナノテラスで活用することを目指す。 S K吸収端(2.47 keV)付近でのXAFS測定は大気吸収による入射X線減衰を避けるため、通常真空環境下で行われるが、真空中での溶液試料の取り扱いは難しい。そこで令和5年度は、He大気圧環境下(2 keV以上のテンダーX線をほぼ透過)でのXAFS測定ができ、かつ溶液試料の取り扱いも容易な、He大気圧XAFS測定装置の設計を進めた。そして、①XAFS+ラマン同時測定用の溶液試料セルを開発し、既存放射光施設での試験を進めるとともに、②多硫化物やSOD1タンパク質などで、適切な試料条件調整(濃度・サンプル量)により溶液試料のXAFSスペクトルを感度よく測定することに成功し、③独自のHe大気圧XAFS測定装置の設計も進めた。

    (1) 分光器や検出器などの備品類を購入し、非線形ラマン散乱の一つであるCARS (Coherent anti-Stokes Raman Scattering) を用いた顕微鏡システムの立ち上げを行った。1秒以下の露光時間で高分子のC-H伸縮振動などに由来するCARSバンドの観測に成功した。次年度では、生細胞測定への拡張、またフィルター類を用いて350 cm-1までの低波数側の測定ができるように最適化する。(2) S-S伸縮振動バンド領域におけるシステインおよびグルタチオンの超硫黄分子のモデル化合物のラマンスペクトルが密度汎関数法を用いて再現し、量子化学計算によって構造解析が行えることを示した。得られた結果をもとに、顕微ラマン分光法を用いたタンパク質内に生成した超硫黄構造の検出を行った。リゾチームなどのタンパク質と硫化ナトリウムとの反応によって生じた超硫黄構造をS-S伸縮振動バンドの変化からその場検出した。現在、微量試料も測定できるように表面増強ラマン散乱(SERS)を用いた超硫黄構造の検出の検討を行っている。(3) ALS関連タンパク質SOD1はオリゴマー化することで毒性が増大することが提案されている。我々はS-S結合がSOD1の酸化毒性と関係することを示し、分子間のS-S結合を介して生成したオリゴマーが強い酸化毒性を生じることを示すことができた。オリゴマーの毒性の起源として酸化毒性を提案できる。また硫化ナトリウムをSOD1に作用させることで超硫黄化したSOD1の作成にも成功し、構造や酸化毒性との関係を検討している。

    液液相分離によって生じたタンパク質液滴について、紫外共鳴ラマン測定などのラマン分光を用いて分析する新規手法を提案することを目的とする。2021年度は、筋萎縮性側索硬化症関連タンパク質FUSおよびそのLC (Low-complexity) 領域 (FUS-LC)、Ataxin-2、さらにマシャドジョセフ病関連タンパク質Ataxin-3について、再現性の高い液滴生成法を確立し、紫外共鳴ラマン測定、水のラマンバンドを用いた強度標準について検討した。紫外共鳴ラマン測定では、硫酸ナトリウムを強度標準とした濃度測定プロトコルを確立し、液滴形成に伴うタンパク質のラマンバンド間の相対強度の変化、ピーク位置の変化について検討した。Ataxin-3を用いて測定を行い、トリプトファン (Trp) とチロシン (Tyr) の共鳴ラマンバンドのピーク位置に液滴形成に伴う変化は無かったが、これらの一部のバンドで強度増加が観測された。共鳴するTrpとTyrの吸収バンドの微小変化を観測していることが考えられる。FUSについても紫外共鳴ラマンスペクトルとTyrの自家蛍光寿命と組み合わせた検討を行っている。ラマン顕微鏡を用いた液滴内のタンパク質のラベルフリー濃度測定では、FUS-LCを用い、pH・塩濃度・試料調製時のFUS-LCの濃度、これらの依存性について系統的な測定を行いさらに液滴の溶解剤として用いられるヘキサンジオール (HD) の添加に伴う液滴内濃度変化の測定も行った。HDの添加に伴い液滴内のFUS-LCの濃度が減少し、液滴内のFUS-LCの濃度がある閾値以下になると液滴が消滅する液滴消滅機構を提案することができた。
