Abstract:

Objective To discuss the effect of microRNA-491-5p(miR-491-5p) over-expression on the proliferation and migration of the human nasopharyngeal carcinoma HONE-1 cells, and to provide the evidence for the study of the pathogenesis and targeted therapy of nasopharyngeal carcinoma. Methods The human nasopharyngeal carcinoma HONE-1 cells were divided into control group (transfected with control plasmid) and miR-491-5p group (transfected with miR-491-5p plasmid). The transfection efficiencies of the HONE-1 cells in two groups were observed under fluorescence microscope; the proliferation activities of the HONE-1 cells in two groups were detected by CCK-8 assay; the number of migration HONE-1 cells in two groups were detected by Transwell chamber assay;the expression levels of Vimentin and E-cadherin mRNA in the HONE-1 cells in two groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method; the expression levels of Vimentin and E-cadherin proteins in the HONE-1 cells in two groups were detected by Western blotting method. Results Compared with control group, the proliferation activities(t=2.832, P=0.0473; t=4.522, P=0.0014; t=9.308, P<0.01) and number of migration HONE-1 cells (t=9.639, P<0.01) in miR-491-5p group at 24,48,and 72 h after treatment were significantly decreased; compared with control group, the expression levels of Vimentin mRNA (t=7.535, P=0.0017) and protein (t=7.219, P=0.0187) in the HONE-1 cells in miR-491-5p group were significantly decreased, and the expression levels of E-cadherin mRNA (t=4.88, P=0.0395) and protein (t=5.754, P=0.0289) were significantly increased. Conclusion Over-expression of miR-491-5p can inhibit the proliferation, migration, and epithelial-mesenchymal transition (EMT) of the human nasopharyngeal carcinoma cells.
