WebApr 11, 2024 · Ferroptosis was initially described as a form of cell death that is induced by erastin and RSL3 through the inhibition of cystine uptake via system x c − and GPX4, respectively . Given that cystine is an essential component of GSH, which is a co-factor of GPX4, the system x c − -GSH-GPX4 pathway was first established as the core defense ... WebDec 1, 2024 · In turn, α-KG supplementation in the presence of cystine cannot trigger ferroptosis either (Gao et al., 2024). These results indicate that dysregulated mitochondrial respiration is a consequence of both a weakening of the antioxidant system and an overriding TCA cycle fueled by glutaminolysis (Okazaki et al., 2024). Therefore, it follows …

The small molecule erastin induces ferroptosis by inhibiting cystine import, resulting in glutathione (GSH) depletion and inactivation of the phospholipid peroxidase glutathione-peroxidase 4 (GPX4) [19].During erastin-induced ferroptosis, glutamate-cysteine antiporter (xc −) is the most …

WebApr 3, 2024 · In addition, cystine is the most restricted amino acid in the process of GSH synthesis, so the cystine-importing GSH-GPX4 machinery is the most critical signaling pathway for preventing ferroptosis. It has been reported that the cystine/glutamate antiporter system Xc - can promote ferroptosis by inhibiting cysteine import. WebFerroptosis can be induced chemically by erastin, which inhibits the glutamate/cystine antiporter, and subsequently suppresses cellular cystine uptake and depletes glutathione.
