Figure 4.

Effects of piceatannol supplementation on the expression levels of protein related to antioxidant in the liver of diquat-induced piglets. The column and its bar represented the means value and SE (n = 6), respectively. Nrf2, nuclear-factor-erythroid-2-related factor 2; Keap1, kelch like ECH associated protein 1; SOD2, superoxide dismutase 2; CON, piglets were orally administrated vehicle solution (0.5% sodium carboxymethyl cellulose) and challenged with sterile saline; DQ-CON, piglets were orally administrated vehicle solution and challenged with diquat (10 mg/kg body weight); DQ-PIC, piglets were orally administrated piceatannol (80 mg/kg/day) and challenged with diquat (10 mg/kg body weight). ^{a, b, c} Different letters on the shoulder mark indicate significant differences (p < 0.05).
