Growth inhibition of the 28 active kinases on different breast cancer cells after siRNA silencing. (A) Percentage growth inhibition of SUM149 by the kinases after siRNA silencing at 5 nM for 72 hours. C, control without siRNA. *PLK1. (B) Percentage growth inhibition of BT474-M1 by the kinases. (C) Percentage growth inhibition of MDA-MB-231 by the kinases. (D) Percentage growth inhibition of HR5 by the kinases. Data are presented as mean ± SD of two independent tests.
