Figure 2. Ischemia did not modify proapoptotic but increased antiapoptotic proteins 3 h after I/R. Effect of ischemia 3 h after reperfusion on Bax (A), Bak (B), Bcl-2 (C), Bcl-x_L (D) protein levels measured by western blot. In (E-F) no modification in Bax/Bcl-2 nor Bax/Bcl-x_L protein ratios were observed at this time. Brown columns denote control retinas (n=6–10), and beige columns denote ischemic retinas (n=8–12). Error bars represent SEM, where *p<0.05 in control versus ischemic retinas as measured by Student's t-test.
