Curcumin and resveratrol prevent B(a)P induced caspase dependent testicular germ cell apoptosis. (A) Light microscopic image of isolated testicular germ cells at ×400 magnification. (B) DNA ladder assay of isolated germ cells. (C) Western blot analysis for cleaved caspase 3, cleaved PARP, cleaved Caspase 8 and cleaved Caspase 9. β Actin was used as the internal loading control. The numerical values indicated below the immunoblots are the densitometric analysis values expressing mean ± SEM of relative arbitrary units of the bands for three immunoblots were conducted with separate experiments in each group. One-way ANOVA was followed by Dunnett multiple comparison test. The level of significance was set at (∗∗∗P < 0.001); (∗∗P ≤ 0.01–0.001); (P ≤ 0.01–0.05) in respect with the control.
