Figure 3. Influence of chicoric acid on antioxidant enzymes in L6 myotubes.

Cells were cultured in the presence or absence of CA (50 µM) for 10 days before measurements of the enzymatic activities of GPx (A) or SOD (B), or analysis of MnSOD protein expression (C). Enzymatic activities are expressed as mU/mg protein and indicated as means ± SEM (n = 5); significantly different from control at * p<0.05. Representative immunoblot is shown.
