Nrf2-related protein expression was regulated by delphinidin in time and concentration dependence. The (a) protein bands and (b) relative protein expression of total Nrf2, Keap1, and HO-1 were reregulated by delphinidin (20 μM) in time dependence. The (c) protein bands (d) and relative protein expression of total Nrf2, Keap1, and HO-1 were regulated by delphinidin (3 h) in different concentrations. β-Actin was used as a loading control for the total protein. Values were presented as mean ± SD. ^∗P < 0.05 vs. the control group.
