Figure 6. Immunoblotting for ER stress and apoptotic markers in the rat retina. A: Representative immunoblots for endoplasmic reticulum (ER) stress markers and apoptotic markers. B: Quantification of the corresponding densitometry data. The protein expression was normalized to the tubulin and was represented
as %control. Data are mean ± standard error of the mean (SEM, n=3). C, control; D, diabetes; D+B12, diabetic rats treated
with vitamin B12. *Significant difference from the control group; #significant difference from the diabetes group (p<0.05). ** and ## indicate respective statistical significance at p<0.01.
