Ferroptosis is a programmed cell death characterized by excessive, iron-dependent accumulation of membrane lipid peroxides due to insufficient glutathione-dependent antioxidant defense. It is influenced by the metabolism of amino acids, lipids, and iron, and occurs in conditions of decreased glutathione peroxidase 4 (GPX4) activity. The increased polyunsaturated fatty acid (PUFA) content in membrane phospholipids is associated with cellular hypersusceptibility to ferroptosis. In contrast, incorporation...
