Cells containing activation of both STAT5 and STAT3 are more sensitive to chemotherapy then cells with only STAT3 activation. MDA-MB-468 cells stably expressing STAT5a1*6 were treated with vehicle or the indicated concentrations of paclitaxel (a) or vinorelbine (b) for 48 hours. Viable cells were quantitated and normalized to each vehicle treated control. Similar results were obtained using two independent stable pools of cells. % v % viia ab biilliit ty y % viability
