Abstract:  

Objective  To investigate the expression of microRNA-1253miR-1253 in lung adenocarcinoma cell lines and its effect on the proliferation migration and invasion of lung adenocarcinoma cells. Methods  Real-time fluorescence quantitative PCR QPCR was used to detect the expression of miR-1253 in lung adenocarcinoma cell lines A549 NCI-H1299 NCI-H157 A973 and GLC-82. miR-1253 mimics and miR-1253 inhibitor were transfected into A973 and NCI-H157 cells respectively. The cells transfected with negative control plasmid NC were used as negative controlNC group. The effects of different expression of miR-1253 on proliferation clone formation invasion and migration of A973 and NCI-H157 cells were examined by cell proliferation assay, clone formation assay and Transwell migration and invasion assay. Results  The results of QPCR showed that the relative expression of miR-1253 in A549 NCI-H1299 NCI-H157 A973 and GLC-82 cells were 0.92±0.06, 0.06±0.03, 1.10±0.26, 0.03±0.01 and 0.45±0.08 respectively. After transfection of miR-1253 mimics into A973 cells the relative expression of miR-1253 increased significantlyP0.05), and decreased significantly after transfection of miR-1253 inhibitor into NCI-H157 cells P0.05. Compared with the NC group the transfection of miR-1253 mimics could significantly inhibit the proliferation activity the ability of plate cloning166.0±29.3 vs. 371.0±31.4 P=0.001 and the ability of migration91.1±32.1 vs. 166.7±33.9 P=0.008 and invasion74.4±20.5 vs. 145.6±28.8P=0.001 of lung adenocarcinoma cell line A973 miR-1253 inhibitor can up-regulate the proliferation number of plate cloning cells545.0±61.9 vs. 337.0±39.7 P=0.008), migration246.7±36.7 vs. 151.1±32.9P0.001 and invasion231.1±38.8 vs. 137.8±27.3 P=0.001 of NCI-H157. Conclusion  miR-1253 could reduce malignant phenotype of lung adenocarcinoma cells and therefore it can be used as an effective target for gene therapy of lung adenocarcinoma.
