Fig. 10From: Radioprotective potential of melatonin against 60Co γ-ray-induced testicular injury in male C57BL/6 miceEffect of melatonin pre-treatment on PCNA protein expression of testes in mice exposed to whole-body 60Co γ-irradiation. Western blot was performed to measured PCNA protein expression after 2h, 4h and 8h post-irradiation. The β-actin protein was used as loading control. *p < 0.001Back to article page
