Fig. 1

A, B. DM833 and DM366 melanoma cells were treated with sub-apoptotic concentrations of ARC, ABT-737 or both as shown for 24 hrs, stained with annexin V-PE/7-AAD and analyzed by flow cytometry. C. U2OS-C3 osteosarcoma cells were treated with ARC, ABT-737 or combination of ARC/ABT-737 for 24 hrs, stained with AnnexinV-PE and analyzed by flow cytometry. D. SKNAS neuroblastoma cells were treated with ARC, ABT-737 and co-treated with ARC and ABT-737 stained with annexin V-PE and 7-AAD and analyzed by flow cytometry. The net percentages of apoptotic cells relative to untreated control are shown in parentheses.
