Ferroptosis is a type of iron-dependent, non-apoptotic cell death, which is typically induced by the suppression of phospholipid hydroperoxide-glutathione peroxidase (GPX4) activity and a corresponding elevation in lipid peroxidation products. While the inhibition of the xCT-mediated uptake of cystine commonly
