WebJan 5, 2024 · Cysteine inadequacy can induce an iron-dependent form of cell death known as ferroptosis (Dixon et al., 2012). Ferroptosis is triggered by the reaction of polyunsaturated fatty acids (PUFAs) in membrane lipids with peroxyl radicals produced from iron (Fe2+) and ROS ( Cao and Dixon, 2016; Yang et al., 2014), thereby inducing lipid … WebApr 12, 2024 · Ferroptosis is an iron-dependent antioxidant system imbalance, characterized by an increase of intracellular iron and a decrease in antioxidant capacity, leading to lipid peroxide (LPO) accumulation. 5 The occurrence of ferroptosis is mainly regulated by various metabolic pathways, including lipid metabolism, amino acid and … WebNov 6, 2024 · We further show that cysteine deprivation can target both (i) glycolytic OCCC by oxidative stress-induced necrosis and ferroptosis and (ii) respiring OCCC by ATP depletion due to iron−sulfur (Fe–S) cluster biogenesis deficit. Cysteine deprivation can potentially overcome metabolic heterogeneity and exhaust metabolic flexibility in OCCC. chiropodist in boston lincolnshire
