Figure 4. ALA upregulates the expression of EPOR in the retina after ONC injury. A: Representative immunoblotting showing erythropoietin receptor (EPOR) protein levels in the whole retina. B: Densitometric analysis of EPOR expression relative to the loading control (mean ± standard error of the mean [SEM], n =
5 per group). Control: sham-operated animal; ONC = optic nerve crush animal; ALA-ONC = alpha lipoic acid (ALA) animal pretreated
1 day before ONC; ONC-ALA = ALA-treated animal 1 day after ONC. * p<0.05, *** p<0.001 compared to the control group, # p<0.05,
### p<0.001 compared to the ONC groups.
