Effect of melatonin pre-treatment on anti and pro-apoptotic proteins expression of testes in mice exposed to whole-body 60Co γ-irradiation. Western blot was performed to measured both the anti (ATM, p53, p21, Bax, Bcl-x, cytochrome C, active caspases-3 and caspases-9 proteins) and pro (Bcl-xL)-apoptotic proteins expression after 2h, 4h and 8h post-irradiation. The β-actin protein was used as loading control. *p < 0.001, **p < 0.01, ns = non-significant (p > 0.05)
