Unraveling the Potential Role of Glutathione in Multiple Forms of Cell Death in Cancer Therapy

Figure 5

The antioxidant role of cellular GSH. Glutathione peroxidase (GPX) converts H2O2 and Lipid-OOH to H2O and Lipid-OH where GSH is oxidized to GSSG, and glutathione reductase (GR) reduced GSSG to GSH dependent on NADPH, thereby forming a redox cycle to prevent oxidative damage.
