SrRan activated MAPK pathways mediated by ERK, JNK, p38, and upregulated the expression of Bax and Bcl-2 in hASCs. a SrRan 1000 μM treatment downregulated Bcl-2 protein, and increased the expression of BAX and phosphorylation of P53in hASCs at 8 and 12 h. b The expression of total and phosphorylated ERK, p38, and JNK was measured by Western blotting in hASCs treated with SrRan 1000 μM at the indicated times. Phosphorylation of ERK was significantly increased at 8 and 12 h. No change occurred with phosphorylation of p38 and JNK after 0, 2, 4, 8, 12, and 24 h. c Results of densitometric scans of blots. Data are means ± SEM for three independent experiments
