Figure 4. mRNA expression of Bad (A), Bax (B), and Bcl-2 (C) in the eye lens of sodium selenite induced and C-PC treated animals. β-actin was used as an internal marker, and the fluorescent intensity was normalized by the intensity of β-actin. Each bar represents mean ± standard error of the mean (SEM) of three independent observations. Statistical significance was considered at p<0.05. ^a Group I versus Group II; ^b represents Group II versus Group III.
