Suppression of p53 protects AML cells from GCS-100/ ABT-737 combination. OCI-AML3 transductant cells with either LKO vector control shRNA or p53 shRNA were treated with vehicle (0.1% DMSO) or GCS-100 (125 µg/ml or 250 µg/ml) or 1 µM ABT-737 for 48 h. Ratio of total viable cells (Ann V −/ DAPI – with bead count; “A”) relative to the average of viable cells treated with DMSO and percentage of apoptotic cells (Ann V +; “B”) was determined by FACSCAN analysis. * represents p < 0.05; ** represents p < 0.01, *** represents p < 0.001 as determined by Student t test.
