So far, several studies reported the antioxidant action of GA (64, 75), and GA could provide the protection for various potential diseases including cancer, cardiovascular disease, and metabolic disease under oxidative stress by restoring the lipid peroxidation levels, normalizing or enhancing the levels of SOD, CAT, GSH-Px, GST, and GSH (76–78). The gene discussed is CAT; the disease is cancer.
