Figure 7. PU activates phase II enzymes through the AMPK pathway.

(A) Neonatal cardiomyocytes were treated with either PE at 100 and 250 μg/mL or PU at 100 μg/mL for 24 h, protein level of NQO-1 was analyzed by western blot. (B) Cells were then treated with PE or PU for 24 h either in the presence or absence of compound (C) protein levels of NQO-1 was analyzed by western blot. Values are means ± S.E.M. (n = 4); *p < 0.05, **p < 0.01.
