Figure 3. Expression of DRO1 sensitizes cells for TRAIL- and TNFα-induced apoptosis. (A, C) DLD1/DRO1 and (B, D) HCT116/DRO1 cells were stimulated with Dox (or left untreated) and treated with increasing amounts of TRAIL- and TNFα, respectively. Cells were stained using propidium iodide and the number of apoptotic cells was determined using flow cytometry.
