WebMay 13, 2024 · Ferroptosis is a novel and unique non-apoptotic cell death form, which is different from apoptosis, necrosis and autophagy, involving iron-dependent ROS formation and lipid oxidation (Yang and Stockwell, 2016). Activation of ferroptosis observed in cancer contributed to destroying the cancer cells (Dixon et al., 2012). WebMany chemotherapeutic drugs can induce ferroptosis in addition to their primary action (e.g., cisplatin, gemcitabine, sorafenib); in preclinical cancer models their action is increased by co-treatment with ferroptosis inducers, such as drugs that inhibit System Xc −, reduce GSH, inhibit GPX4, or alter intracellular iron levels (Su et al ...
