A significant mechanistic advance is the reclassification of the classic inhibitor P4S

A recent study also demonstrated mislocalization of APE1 from the nucleus to the cytoplasm as a possible trigger of oxidative DNA damage in spinal motor neurons expressing mutant SOD1 G93A , despite upregulation of multiple DNA repair enzymes, suggesting that restricted localization of APE1 could inhibit redox homeostasis (Li J
This discrepancy of iron chelation worsening neurodegeneration characterised by local iron overload raises a critical question: why does iron chelation block ferroptosis induced by pro-ferroptotic agents such as RSL3 and erastin (where there is no iron elevation in cell culture), yet fail to protect in the context of human neurodegenerative disease where iron is elevated
In numerous epimutants (UR2, UR8 to UR30), a heterochromatin island impinges on the promoter region of the essential cup1 + gene (Torres-Garcia et al, 2020b), which encodes a mitochondrial LYR protein predicted to be an assembly factor for mitochondrial electron transport chain (ETC) complexes (Angerer, 2015)
Particularly useful are polyvinyl alkylene ethers, such as polyethylene glycol, polypropylene glycol (PEG)
