WebBy oxidizing GSH, GPX4 can reduce peroxidized lipids, thus, inhibition of GPX4 or cystine import can induce ferroptosis . In addition, coenzyme Q10 (CoQ10) can reverse lipid peroxidation independent of GPX4, ferroptosis suppressor protein 1 (FSP1) can act as an oxidoreductase of CoQ10, shuttling reductants to the lipid bilayer plasma membrane ...
