WebThe mechanism of H(2)O(2) induced oxidative stress leading to male germ cell apoptosis was earlier reported from our laboratory. In the present study, we investigated the mechanisms by which N-acetyl-L-cysteine (NAC, which is highly cell specific with strong antioxidant and anti-genotoxic properties), stimulated cell survival under such conditions. 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 …

Recall peroxides are potent oxidizing agents due to the weakness of the O − O single bond. It is this same weak bond that causes hydrogen peroxide to be dangerous when produced in our bodies, as it can react spontaneously with oxygen or nitrogen nucleophiles and p bonds.
