Effects of Plk1 KD on smooth muscle cell proliferation. a Smooth muscle cells expressing control shRNA or Plk1 shRNA were treated with 20 ng/ml PDGF for 24–72 h. The numbers of viable cells were then determined. Plk1 KD inhibits smooth muscle cell proliferation. Data are mean ± SE (n = 4, * P < 0.05, **P < 0.01). b Smooth muscle cells expressing control shRNA or Plk1 shRNA were treated with or without 20 ng/ml PDGF for 24 h. DNA synthesis in these cells was evaluated using the BrdU incorporation assay. Newly-synthesized DNA was reduced in Plk1 KD cells. Data are mean ± SE (n = 6, ** P < 0.01)
