Western blot analysis in K562R cells. The relative expression level of the cleaved proteins was analyzed for caspase-3 (A), caspase-9 (B), caspase-7 (C) and PARP (D). β-actin was used as a loading control. The results are presented as the ratio of cleaved proteins compared to β-actin intensities. ^**, P < 0.01 vs. Control, ^##, P < 0.01 vs. 1 μmol/L IM, ^■■, P < 0.01 vs. 5 μg/mL DHTMF.
