Figure 4. Effects of resveratrol on the expression of Nrf2-related proteins. Representative western blot analysis of Nrf2 expression in total and nuclear proteins, and Keap1 expression in total protein (A). The results showed that the total and nuclear Nrf2 protein levels were decreased in the RSV group compared to that in the control (Cont) group (B, C). There were no differences in Keap1 protein expression between both groups (D). Quantitative analysis of the results is shown (*P<0.05, †P<0.01).
