    Intercellular cleaning via autophagy is crucial for maintaining cellular homeostasis, and impaired autophagy has been associated with the accumulation of protein aggregates that can contribute to neurological diseases. Specifically, the loss-of-function mutation in the human autophagy-related gene 5 (ATG5) at E122D has been linked to the pathogenesis of spinocerebellar ataxia in humans. In this study, we generated two homozygous C. elegans strains with mutations (E121D and E121A) at positions corresponding to the human ATG5 ataxia mutation to investigate the effects of ATG5 mutations on autophagy and motility. Our results showed that both mutants exhibited a reduction in autophagy activity and impaired motility, suggesting that the conserved mechanism of autophagy-mediated regulation of motility extends from C. elegans to humans.

    Targeted degradation is a promising new modality in drug discovery that makes it possible to reduce intracellular protein levels with small molecules. It is a complementary approach to the conventional protein knockdown typically used in laboratories and may offer a way to approach the currently undruggable human proteome. Recently, the first autophagy-mediated degraders, called AUTACs, were developed based on observations in a xenophagy study.

    Protein silencing represents an essential tool in biomedical research. Targeted protein degradation (TPD) strategies exemplified by PROTACs are rapidly emerging as modalities in drug discovery. However, the scope of current TPD techniques is limited because many intracellular materials are not substrates of proteasomal clearance. Here, we described a novel targeted-clearance strategy (autophagy-targeting chimera [AUTAC]) that contains a degradation tag (guanine derivatives) and a warhead to provide target specificity. As expected from the substrate scope of autophagy, AUTAC degraded fragmented mitochondria as well as proteins. Mitochondria-targeted AUTAC accelerated both the removal of dysfunctional fragmented mitochondria and the biogenesis of functionally normal mitochondria in patient-derived fibroblast cells. Cytoprotective effects against acute mitochondrial injuries were also seen. Canonical autophagy is viewed as a nonselective bulk decomposition system, and none of the available autophagy-inducing agents exhibit useful cargo selectivity. With its target specificity, AUTAC provides a new modality for research on autophagy-based drugs.

    Nitric oxide (NO) raises the intracellular 3',5'-cyclic guanosine monophosphate (cGMP) level through the activation of soluble guanylate cyclase and, in the presence of reactive oxygen species (ROS), reacts with biomolecules to produce nitrated cGMP derivatives. 8-Nitro-cGMP was the first endogenous cGMP derivative discovered in mammalian cells (2007) and was later found in plant cells. Among the six nitrogen atoms in this molecule, the one in the nitro group (NO2) comes from NO. This chapter asserts that this newly found cGMP is undoubtedly one of the major physiological cNMPs. Multiple studies suggest that its intracellular abundance might exceed that of unmodified cGMP. The characteristic chemical feature of 8-nitro-cGMP is its ability to modify proteinous cysteine residues via a stable sulfide bond. In this posttranslational modification, the nitro group is detached from the guanine base. This modification, termed "protein S-guanylation," is known to regulate the physiological functions of several important proteins. Furthermore, 8-nitro-cGMP participates in the regulation of autophagy. For example, in antibacterial autophagy (xenophagy), S-guanylation accumulates around invading bacterial cells and functions as a "tag" for subsequent clearance of the organism via ubiquitin modifications. This finding suggests the existence of a system for recognizing the cGMP structure on proteins. Autophagy induction by 8-nitro-cGMP is mechanistically distinct from the well-described starvation-induced autophagy and is independent of the action of mTOR, the master regulator of canonical autophagy.
