Ferroptosis, a novel pharmacological mechanism of anti-cancer drugs

Ferroptosis, a form of regulated cell death, is initiated by oxidative perturbations of the intracellular microenvironment, which is under the constitutive control of glutathione peroxidase 4 (GPX4). Ferrous iron (Fe2+) accumulation and lipid peroxidation are critical events in the induction of ferroptosis, which is inhibited by iron chelators and lipophilic antioxidants. Ferroptosis terminates in mitochondrial dysfunction and toxic lipid...
