Effect of QL on cell vitality and apoptosis of ischemia hypoxic cultivated NRCMs. A: MTT assay showed the OD value of Q group increased significantly compared with V group; B: Flow cytometry confirmed that QL treatment improved cell apoptosis, preincubation of Akt inhibitor GSK69069 can block this effect as the OD value and apoptotic rate in Q+G group showed no significant difference with V group. C: Control group, V: Vehicle group, Q: QL-treated group, G: GSK69069 group, Q+G: QL + GSK69069 group. Values are expressed as the mean ± SD, one-way ANOVA followed by the Tukey post-hoc were applied,*P<0.05 vs. V group, #P<0.05 vs. Q+G group.
