Effect of PA on proliferation and oxidative stress of H9c2 cells
(A) Cells were treated with various concentrations (100–800 µM) of PA for 24 h and then processed for cell viability analysis. (B) Cells were treated with various concentrations (100–800 µM) of PA for 24 h and then processed for the ROS assay. (C) Cells were treated with various concentrations (100–800 µM) of PA for 24 h and then analyzed for NOX2 expression. NOX2 expression was normalized to β-actin levels. Data are presented as the mean ± S.E.M. of three independent experiments, *P<0.05, **P<0.01 versus the control group.
