Fig. 4From: Electromagnetic radiation at 900 MHz induces sperm apoptosis through bcl-2, bax and caspase-3 signaling pathways in ratsThe comparison in expressions of cytochrome c, bcl-2, bax and caspase-3 between the exposure and control. Densitometric analyses of cytochrome c, bcl-2, bax and caspase-3 in sperm of rats between exposure group and control group. The intensities of bcl-2, bax and caspase-3 were normalized with the β-actin and the intensity of cytochrome c was normalized with VDCA1. Bars represent Mean ± SEM (n = 15). *indicated a significant difference at P = 0.05Back to article page
