Synergistic effect of AEE788 and rapalogs on proliferative inhibition and cell death in rapalog-resistant TNBC cells. a Proliferative response of rapalog-resistant SUM149PT (left panel) and HCC1143 (right panel) TNBC cells, to rapalogs Rap, Tem, and Eve in concentration range alone or combined with 0.316 µM and 1 µM AEE788, respectively. b IC50 values (µM) of rapalogs in combination with AEE788, inducing 50% of proliferation inhibition in SUM149PT and HCC1143 cells. c Combination index (CI) of rapalog and AEE788 in SUM149PT and HCC1143 cells. CI < 1 indicates synergism. d, e Combinatorial effects of Rap and AEE788 on SUM149PT (left panel, d) and HCC1143 (right panel, e) cell death. Cells were subjected to Annexin V/Propidium Iodide (AnV/PI) apoptosis assays after treatment for 24, 48, 72, and 96 h. Cisplatin (100 µM) was used as positive control. (two-way ANOVA *p < 0.05, **p < 0.01, ***p < 0.001)
