Natural phytochemicals of plant origin, including flavonoids, have been found to be potent antioxidants providing beneficial effects against oxidative stress-related diseases. The present study was carried out to investigate the antioxidant properties of morin, a flavonoid originally isolated from the flowering plants of the Moraceae family. Superoxide dismutase (SOD)like activity and 2,2'azinobis(3ethylbenzothiazoline6sulfonic acid) (ABTS•+) radical scavenging activity were determined. We also investigated the cytoprotective effects of morin against hydrogen peroxide (H2O2)induced DNA damage and apoptosis in V794 Chinese hamster lung fibroblasts. Our results demonstrated that morin had strong scavenging effects against ABTS•+ radicals with enhanced SOD activity, which varied in a dose-dependent manner. Morin was found to reduce H2O2induced intracellular reactive oxygen species generation and nuclear DNA damage, and it recovered cell viability damaged by H2O2 via inhibition of mitochondrial dysfunctionmediated apoptosis. Notably, the treatment of V794 cells with morin markedly enhanced the expression of heme oxygenase1 (HO1) but not quinone oxidoreductase-1, which was associated with the increased expression and phosphorylation of nuclear factor-erythroid¬†2-related factor¬†2 (Nrf2) and the downregulation of Kelchlike ECHassociated protein¬†1 expression. Based on our findings, we conclude that morin effectively ameliorated oxidative stressinduced DNA damage through intrinsic free radical scavenging activity and activation of the Nrf2/HO-1 pathway.
