Abstract: Objective To investigate the effects of miR-19 on the migration ability of lung adenocarcinoma cell line A549. Methods The expressions of miR-19 in lung epithelial cell line BEAS-2B and lung adenocarcinoma cell line A549-Luc were detected by qRT-PCR.The A549-Luc cell line which over-expressed miR-19 was established. The expression levels of miR-19 in A549/RFP+/H2B and A549/RFP+/m19 were identified by qRT-PCR. The morphology of A549/RFP+/m19 was observed,and the migration ability of A549/RFP+/m19 was detected by transwell migration assay. Results The expression levels of miR-19 differed significantly between BEAS-2B cells and A549-Luc cells (t = -20.954, P < 0.001). The lung adenocarcinoma cell line A549/RFP+/m19 which over-expressed miR-19 was successfully established. Changes in A549/RFP+/m19 cell morphology were found. As compared with A549/RFP+/H2B cells, A549/RFP+/m19 had an increased migration ability (P <0.01). Conclusions miR-19 enhances the migration ability of lung adenocarcinoma A549-Luc cells.
