Curcumin supplementation attenuates apoptosis in the testis. (A) Immunohistochemical staining for the protein expression levels of Bcl-xl and Fas, and TUNEL for the apoptotic cells in the testis (n=6; magnification ×100 and ×400; scale bar 100 and 20 μm on the upper and lower panels, respectively). Bcl-xl and Fas are predominantly observed in the interstitial cells. Arrows indicate positive expression. (B–D) Quantitative analysis of AI and the OD (n=6). The data are expressed as the mean ± standard error of the mean (*P<0.05, HFD vs. control group; #P<0.05, curcumin vs. HFD group). HFD, high-fat diet; Bcl, B-cell lymphoma; OD, optical density; AI, apoptosis index; TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling.
