The expression of miR-148b analyzed using real time quantitative PCR (qRT-PCR). miR-148b mimics (miR-148b) or negative control mimics (NC, shRNA control) were stably transfected into non small cell lung cancer cell lines PC14/B and A549 cells. The blank groups (blank) were transfected with unpackaged lentiviral vectors at the same MOI. The expression of miR-148b in PC14/B and A549 cells were assessed by qRT-PCR. U6 RNA was used as an internal control
