From: PPM1D silencing by RNA interference inhibits the proliferation of lung cancer cells
Effect of PPM1D knockdown on the cell cycle distribution of H1299 cells. (A) Percentage of cells residing in each checkpoint of the cell cycle. (B) Cyclin B1 protein expression levels of Lv-shPPM1D infected, Lv-shCon infected and non-infected H1299 cells analyzed by Western blotting. Values are the mean of three independent experiments; bars represent SD. *P < 0.05 and **P < 0.01 in comparison with the control. Con, control.
