Effects of miR-21 inhibitors on the proliferation and clone formation of A549 cells. (A) The effect of miR-21 inhibitors on the proliferation of A549 cells detected by MTT assay; (B) the effect of miR-21 inhibitors on the clone formation of A549 cells measured by colony-forming assay (mean and standard deviation).
Notes: *Compared with the NC group or mock group, P<0.05; **compared with the NC group or mock group, P<0.01.
Abbreviations: miR-21, microRNA-21; IN, inhibitor group; NC, negative control group; mock, mock group; OD, optical density.
