Figure 4

Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay and western blot analysis for detecting cell apoptosis of prostate tissues. (a–d) Representative figures from TUNEL staining of prostate tissues for the control, EP, BPH, and EP+BPH groups, respectively. Tissue cell nuclei were stained blue with DAPI; TUNEL-positive nuclei were stained green. ; original magnification ×200. (e) A bar graph for apoptosis rate (%) of TUNEL-positive cells in rat prostate. (f) Representative protein bands for Bax and Bcl-2 in prostate tissues among the indicated groups. (g) Quantitative analysis of the protein level of Bax relative to GAPDH. (h) Quantitative analysis of the protein level of Bcl-2 relative to GAPDH. Data are presented as (, , and ).
