Effect of PCE on α-SMA and PCNA expression in the renal glomeruli. (A) Immunofluorescence staining for α-SMA and (B) PCNA 400× magnification. Western blot analysis of (C) α-SMA and (D) PCNA expression in the renal cortex for each group. All data are expressed as the mean ± SEM (n=8). *P <0.01 vs. NOR group; #P <0.01 vs. DM group, and +P <0.01 vs. PCE-100 group.
