Web29 aug. 2024 · Ferroptosis is an iron-dependent programmed cell death, which is different from apoptosis, necrosis, and autophagy. Specifically, under the action of divalent iron or ester oxygenase, unsaturated fatty acids that are highly expressed on the cell membrane are catalyzed to produce lipid peroxidation, which induces cell death. WebCR and metformin attenuate ferroptosis by activating the AMPK pathway, which has been associated with extended lifespan and health span and improved frailty ( 51 ).
