ABSTRACT
Objective · To study the regulation of hsa-miRNA124-3p on the proliferation and migration of human lung cancer NCI-H460 cells and its mechanism. Methods · Four pairs of lung cancer and para-carcinoma tissues were harvested in clinical and measured for hsa-miRNA124-3p and Krüppellike factor 4 (KLF4) levels. The theoretical binding site of hsa-miRNA124-3p in 3'-UTR of KLF4 was predicted by bioinformatics, and validated by luciferase report assay. NCI-H460 cells were transfected with pshRNA-Sponge-miRNA124 or pshRNA-KLF4, and 48 hours later, the proliferation of NCI-H460 cells after genetic intervention was assayed by the MTT method, and cell migration ability was observed by streak method. Results · For all four pairs of samples tested, hsa-miRNA124-3p was higher in the cancer tissues than in the adjacent tissue (P0.05). The data of cell migration assay showed that the changes of cell migration ability were the same as proliferation activity of the cells in groups 72 h after transfection. Conclusion · Hsa-miRNA124-3p increases the proliferation and migration in NCI-H460 cells via suppressing the expression of KLF4, and reducing the content of miRNA124-3p in NC-H460 cells can inhibit cell proliferation and migration via upregulating KLF4 expression.
