摘要 Ferroptosis is a form of regulated cell death characterized by iron-dependent overaccumulation of lipid peroxides,which causes membrane damage and cell lysis.Ferroptosis can be prevented by cellular antioxidant mechanisms such as glutathione peroxidase 4(GPX4)-mediated elimination of the lipid peroxides at the cost of glutathione(GSH).As the rate-limiting step of GSH synthesis,the availability of intracellular cystine is controlled by the cell membrane-located cystine/glutamate antiporter system xc−.Indeed,the initially identified small molecule inducers of ferroptosis,RSL3 and erastin,turned out to be inhibitors of GPX4 and system xc−,respectively.
