Disruption in iron homeostasis, including increased transferrin receptor expression and ferritin degradation via NCOA4-mediated ferritinophagy, contributes to ferroptotic susceptibility ( Lipid Peroxidation: Polyunsaturated fatty acids (PUFAs), especially arachidonic and adrenic acids, are substrates for lipoxygenases (LOX), which drive peroxidation in membrane phospholipids, generating cytotoxic lipid peroxides such as 4-hydroxynonenal (4-HNE) and malondialdehyde (MDA) ( Glutathione Depletion and GPX4 Inactivation: System Xc imports cystine for GSH synthesis
