Effect of dioscin on the expression level of Bcl -2 protein in MC3T3 -E1 cells. Cells were treated with vehicle, different concentrations of dioscin (0.25 μg/ml, 0.5 μg/ml and 1.0 μg/ml) or lovastatin (0.04 μM) for 24 h, and then the expression level of Bcl-2 protein was examined by Western blot. Results were obtained from three independent experiments and were expressed as mean ± SD. **P < 0.01 vs Control.
