WebCysteine metabolism plays a critical role in the initiation of ferroptosis. 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 6, 2024 · Mechanistically, ROS induce the consumption of NADPH for their detoxification, which lowers the inhibition of the first and rate-limiting enzyme of the PPP, glucose-6-phosphate dehydrogenase...
