WebOct 14, 2024 · Once imported into the cytosol, cystine is reduced to cysteine for subsequent synthesis of glutathione (GSH), which is then used as a key cofactor by glutathione peroxidase 4 (GPX4) to detoxify lipid peroxides accumulated on cellular membranes, thereby mitigating ferroptosis ( Fig. 1A) ( Yang et al., 2014 ). WebJun 15, 2024 · The cystine transporter SLC7A11 was identified as a druggable target downstream of the MCU-Nrf2 axis. Paradoxically, despite the increased ability to uptake cystine, MCU-overexpressing PDAC demonstrated characteristics typical of cystine-deprived cells and were hypersensitive to cystine deprivation-induced ferroptosis.
WebOct 1, 2024 · Ferroptosis is an iron-dependent form of regulated cell death induced by lethal accumulation of lipid peroxides in the cellular membrane, and is mechanistically … WebFerroptosis can be induced by inhibiting GPX4 (20, 21) or by limiting the supply of GSH to GPX4 . Cysteine is the rate-limiting substrate for the synthesis of GSH. Cystine uptake is mediated by the cystine/glutamate …
WebFerroptosis can be induced chemically by erastin, which inhibits the glutamate/cystine antiporter, and subsequently suppresses cellular cystine uptake and depletes glutathione. Glutathione is fundamental in maintaining the redox balance and defending against oxidative stress, including reactive oxygen species (Kim et al., 2015). WebMar 6, 2024 · Ferroptosis is characterized by overwhelming iron accumulation and lipid peroxidation. Erastin is a small molecule that blocks cystine uptake into cells by inhibiting the specific light-chain subunit of the cystine/glutamate antiporter (SLC7A11 or …
