Figure 2: Effects of Sal B and perindopril (PER) on AT1R and ERK expression in rat liver. Protein was extracted from rat liver and the samples were electrophoresed and analyzed by western blot with AT1R (a) or ERK/pERK (b) antibodies. ((c) and (d)): Quantities for densitometric analysis of AT1R and ERK/pERK. Each bar represents the means ± S.D. of three rats assayed in triplicate. ** versus normal; ## versus model.
