Calculation of optimal doses required for co-treatment of CRC cells by Thiostrepton and NS398. HT29 and Caco-2 cells were treated with 0.5, 1.0, 5.0, 10 and 25 μM Thiostrepton or 1.0, 10, 25, 50 and 100 μM NS398 alone or in different combinations to calculate the Synergistic apoptotic response of Thiostrepton and NS398 for 48 h and dose effect (a and c) and Fractional effect (b and d) graphs were generated using Calcusyn software. Apoptotic response analysis was done as mean ± SD values normalized to control. Combination indices were calculated using Chou and Talalay methodology
