Fig. 5. Variation in Akt and ERK 1/2 phosphorylation (A and B) and in Cleaved Caspase 9 and Cytochrome C expression (C and D) in RPE cells, measured by Western blot and densitometric analysis. Densitometric analysis and an example of Western blot taken from 5 different experiments are shown in Fig.s A and B for p-Akt and p-ERK1/2, respectively, and in C and D for Cleaved Caspase 9 and Cytochrome C, respectively. Abbreviations are as in previous Fig.s. The data were normalized versus control value. Reported data are means SD of five independent experiments for each experimental protocol. Significance between groups: *P<0.05 vs C; #P<0.05 vs 200 μM H2O2.
