a Immunoblot analysis of PLK1 and GAPDH in TNBC cell lines. b Immunoblot analysis of PLK1 and GAPDH in TNBC lines transfected with control siRNA (si-control) or siRNA targeting PLK1 (siPLK1). c Immunocytochemical analysis of PLK1 in MDA-MB-436 cells. The most right panel shows a pseudocolor image of PLK1. A white arrow indicates accumulation of PLK1 in the spindle. d The cell viability of TNBC lines transfected with si-control or siRNA targeting PLK1. Data were mean ± S.D. from 3 independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001
