Using the CalcuSyn program, CI values were calculated and Conjugating enzyme inhibitor these have been summarized in Figures 2c and 2d. The CI values for 267/Dt combinations were, generally speaking, below 0. 9 for both LCC6Her2 and LCC6 treated cells, showing weak to strong synergistic relationships. Notably, the CI values were consistently below one over a broad selection of effective doses as define by the fraction affected value. The mix of 267 and Dt was also evaluated in several other breast cancer cell lines. CI values were calculated from cell viability dose response curves. These data are summarized in Figure 2e, which reveals the CI values determined at the ED50. The indicate that the observed synergistic relationships are accomplished in at least five of the six cell lines tested. For KPL 4 cells the calculated CI values were indicative of somewhat hostile interactions. If drug combinations interact in a manner that end up in synergy, then the dose Ribonucleic acid (RNA) of each drug found in the mix to achieve a certain measurable effect level will be substantially reduced when weighed against the dose required to achieve the same effect level when the drugs are given alone. This parameter may be calculated and is described from the DRI. The DRI can be used to estimate the doses of 267 and Dt needed when used in combination to achieve a defined effect stage which can then be weighed against the single agent dose required to achieve this effect. Based on these analyses, it was estimated that the concentration of 267 in the 267/Dt combination required to achieve an ED50 may be reduced by up to 3. 6 fold in the LCC6 cell line. 267 dose reductions were less impressive within the other cell lines evaluated, including no change to your 30% reduction. A similar analysis was completed for Dt and it was estimated that the concentration of Dt in VX-661 the 267/Dt mix needed to achieve an ED50 might be paid down in most cell lines by 2 to 25 fold in comparison with Dt alone. Like in cells the ED50 of Dt presented alone is 5 nM during combination with 267 the ED50 of Dt decreases to less than 1 nM. 267 and 267/Dt combination treatments cause dose-dependent reduction in P AKT levels projected by western blot analysis Western blot analysis was used to examine P AKT levels in LCC6 and LCC6Her2 cells treated with increasing concentrations of 267 alone, Dt alone, or 267 in combination with Dt. In these reports P AKT was measured eight hours after addition of 267, a time point selected because no significant changes in cell viability were noted yet significant reductions in P AKT were noticeable as noted in the representative european blots shown in Figure 4. P AKT levels were paid down in a dose-dependent fashion on the array of 267 levels examined in both LCC6 and LCC6Her2 cells. Dt treatment alone was proven to have little or no measurable impact on P AKT levels.
