BY extract inhibits EtOH-induced oxidative stress in HepG2 cells. Western blot analysis for antioxidants, including SOD1, SOD2, catalase, GPx using cells treated with BY extract and/or EtOH (a) and the densities of SOD1 (b), SOD2 (c), catalase (d), and GPx (e) proteins were calculated with HD9 imaging software. The results are shown as the mean ± SEM in triplicate (n = 6). ## p < 0.01 and ### p < 0.001 vs. control. * p < 0.05, ** p < 0.01, and *** p < 0.001 vs. ethanol-alone-treated group. Cont, control; BY extract, bulbil of yam extract; EtOH, ethanol; SOD 1, superoxide dismutase 1; SOD 2, superoxide dismutase 2; GPx, glutathione peroxidase.
