Western blot analysis. A Western blot analysis of BCl-2, BAX and levels of cleaved caspase-3 expression in heart tissue of Etpost (2 μg/ml) adjusted relative to GAPDH and IR. B Western blot analysis of GSK-3β and SGK1 expression in the heart tissue of Etpost (2 μg/ml) adjusted relative to GAPDH and IR. GAPDH was used as a loading control. The data were expressed as mean ± SEM. *P < 0.05 vs. IR group. Etpost: ethyl acetate fraction of P. reptans root
