From: The expression of PLK-1 in cervical carcinoma: a possible target for enhancing chemosensitivity
PLK-1 knockdown by siRNA transfection modulated proliferation and caspase-3 activity in HeLa cells. A, PLK-1 knockdown significantly inhibited cell proliferation, as determined by MTT assay; B, Cell proliferation curve for four groups of HeLa cells was presented, as determined by MTT assay; C, PLK-1 knockdown significantly increased caspase-3 activity in HeLa cells, as determined by Fluorescent Assay. Data are the means of three independent experiments. * P < 0.05 compared to the control cells.
