WebJan 1, 2024 · The cyst(e)ine/GSH/GPX4 antioxidant axis is one of the most important axes for ferroptosis defense, which is fueled by NADPH. Although lipid peroxidation has been reported as one major effector by which UV contributes to photoaging and skin cancer, it remains unclear if ferroptosis is involved in UV irradiation-induced skin damage. WebJan 25, 2024 · As GPX4 is the major PLOOH-neutralizing enzyme, a general mechanism underlying erastin/RSL3-induced ferroptosis emerged: both compounds inactivate GPX4 – RSL3 does so directly, and erastin does so indirectly by inhibiting cystine import, thus depriving cells of cysteine, an essential cellular antioxidant and a building block of GSH.
