Fig. 7From: Influence of three BALB/c substrain backgrounds on the skin tumor induction efficacy to DMBA and TPA cotreatmentProtein expressions of Bax, Bcl-2 and Caspase-3 in tumor samples from the DMBA+TPA treated a BALB/cKorl, b BALB/cA and c BALB/cB substrains. Expression levels of Bax, Bcl-2 and Caspase-3 proteins were determined by Western blot analysis using HRP-conjugated anti-rabbit IgG antibodies. Band intensity of each protein was measured using an imaging densitometer, and expressions of the three proteins were calculated relative to the intensity of β-actin protein. Data represent the mean ± SD. *, p < 0.05 compared to the No treated group. #, p < 0.05 compared to the Vehicle treated groupBack to article page
