The expression of superoxide dismutase (SOD), 4-hydroxynonenal (4-HNE), cytochromec, and cleaved caspase 3. Proteins were subjected to Western blotting using antibodies against SOD, 4-HNE (A) cytochrome c, and cleaved caspase 3 (D) and quantified by densitometric scanning, results being expressed in arbitrary units. Figure (B) and (C) present the expression of SOD, 4-HNE, while (E) and (F) for cytochrome c, and cleaved caspase 3. Values are the mean ± SEM for five independent determinations. *Statistically significant difference (P < 0.05), catechin (-) COM (+) vs. catechin (+) COM (+).
