Figure 7. Sensitization of BT-474R cells to Trastuzumab.
Effect of Pak and β-catenin inhibitors on survival of BT-474R cells. (A) Cells were treated with the indicated amounts of PF-3758309 and/or iCRT14 for 4 days and the viability was determined by trypan blue exclusion. (B) Combination of PF-3758309 and/or iCRT14 treatment sensitizes BT-474R cells to trastuzumab. Cells were treated with the indicated amounts of PF-3758309 and/or iCRT14 in the presence or absence of trastuzumab for 4 days, collected and apoptosis was measured calculating the percent of positive Annexin V-PE cells by flow cytometry. The data are representative of three independent experiments. Bars, SD. *p<0.05.
