Synergistic effect of AR and mitogen-activated protein kinase kinase inhibitors on cell viability. (A) MTT assay to measure cell viability in MDA-MB-453 cell line after monotherapies and combination treatments with flutamide (FLU) and CI-1040 (CI) at 5 and 10 μM concentrations. CTL: control. Error bars: ± 2 SEM. (B) Combination indices (CI) for flutamide and CI-1040 combination therapy in MDA-MB-453 cell line using MTT assay. Cell viability was measured after combination therapies with flutamide at 5 and 10 μM with each concentration of CI-1040 at 5 and 10 μM. The concentrations of FLU and CI-1040 monotherapies with an effect similar to that of each combination therapy are depicted. Error bars: ± 2 SEM. (C) Combination indices for flutamide and CI-1040 combination therapy in HCC-1954 cell line using MTT assay. Cell viability was measured after combination therapies with flutamide at 20 and 40 μM with each concentration of CI-1040 at 5 and 10 μM. (D) Combination indices for flutamide and CI-1040 combination therapy in HCC-202 cell line using MTT assay at concentrations described in Figure 2C.
