Figure 2From: PPM1D silencing by RNA interference inhibits the proliferation of lung cancer cellsEffect of siRNA-mediated PPM1D knockdown on the proliferation of lung cancer cells. A549 (A) and H1299 (B) cells analyzed using the MTT assay. (C). Light microscopic and fluorescence microscopic pictures of the colonies of A549 cells. Colonies were stained with Giemsa staining after 8 days of infection. Number of colonies of Lv-shPPM1D infected, Lv-shCon infected and non-infected A549 (D) and H1299 (E) cells. Values are the mean of three independent experiments; bars represent SD. **P < 0.01 and ***P < 0.001 in comparison with the control. Con, control; OD, optical density.Back to article page
