INZ significantly enhances the proapoptotic effect of DOX on H460 and HCT116 cells. H460 (A) and HCT116p53+/+ (B) were plated in 6-cm-diameter dishes and treated with INZ or/and DOX at the indicated concentrations for 48 hours. Apoptotic cells were analyzed as described above inFigure 5. The data were expressed as means ± SEM (n = 4).
