Effect of PPE on AR, PCNA, and TNFα expression in prostate. The expression of (A,B) AR, (C,D) PCNA, and (E,F) TNFα were analyzed by IHF. Representative immunofluorescence images were shown and colabeled with Hoechst 33,258 (blue). Magnification 10×; scale bar, 100 µm. The densities of proteins were calculated using ACT-1 software. Data represent arbitrary intensity relative to CON (control) as the mean ± SD of 4 rats per experimental group. ### p < 0.001 compared with control group, and values with different letters indicate significant differences, * p < 0.05, ** p < 0.01, and *** p < 0.001, compared with the BPH group.
