WebApr 10, 2024 · Glutathione peroxidase 4 (GPX4), a unique antioxidant enzyme, can reduce lipid hydroperoxides to lipid alcohols and prevent ROS accumulation in the body, has been proven to be an essential inhibitor of ferroptosis [ 15 ]. GPX4 is highly expressed in human pan-carcinoma tissues and negatively correlated with survival time [ 16 ]. WebThe importance of the GPX4/GSH detoxification mechanism in preventing ferroptosis is demonstrated by the fact that genetic deletion or pharmacological inhibition of GPX4 as well as downregulation of its cofactor GSH by any means will cause an accumulation of lipid ...
