A. Apoptosis was detected by in situ TUNEL (green) and DAPI (blue). B. Quantitative analysis of TUNEL-positive cells content. C. The protein levels of Bax, P53, Bcl-2, and Bcl-xl. D. The values from densitometry of Bax, P53, Bcl-2, and Bcl-xl were normalized to the level of GAPDH protein and expressed as fold increased. Data are expressed as mean ± SEM of 4 independent experiments. * Significantly different (P < 0.05) from control group, and ^# significantly different (P < 0.05) from Pb-treated group.
