[Retracted] Biomolecular Modulation of Neurodegenerative Events during Ageing

Figure 5

Caspase-3 immunolocalization in the sections of the optic nerve head (a/b/c) and in the retina (a′/b′/c′). ((a) and (a′)) Young rat without caspase-3 immunolocalization (6 months, negative control). ((b) and (b′)) Aged rat fed normally with high caspase-3 expression. ((c) and (c′)) Aged rat after oral supplementation of α-lipoic acid (ALA) and superoxide dismutase (SOD) with reduced immunofluorescence, indicating lower caspase-3 expression.
