Maduramicin activates PP2A in H9c2 cells. H9c2 cells were exposure to maduramicin at indicated concentrations for 24 h. A. Total cell lysates were subjected to Western blotting using indicated antibodies. B. Blots for indicated proteins were semi-quantified using NIH image J. For (A), representative blots were shown. The blots were probed for GAPDH as a loading control. Similar results were observed in at least three independent experiments. For (B), all data were expressed as means ± SE (n = 3). Statistical analysis was performed using one-way ANOVA followed by Dunnett’s post-test. ** P < 0.01, difference with control group.
