Fig. 3. Knockdown BMP-9 or ALK1 inhibited A549 and NCl-H1650 cells proliferation. Knockdown BMP-9 or ALK1 was confirmed by western blotting in A549 (A) and NCl-H1650 (C) cells. Knockdown BMP-9 or ALK1 inhibited A549 (B) and NCl-H1650 (D) cells proliferation in CCK8 assay. Data were represented as the mean ± SEM. #p < 0.05 versus Sh-Con group, ##p < 0.01 versus Sh-Con group, ##p < 0.001 versus Sh-Con group.
