Background: This experimental design was based on lncRNA LINC01194 to explore the pathogenesis of NSCLC.
Methods: RT-qPCR was used to detect the expression of lncRNA LINC01194 and miR-486-5p in NSCLC tissues and cell lines. CCK-8, colony formation, and transwell assays were used to examine the effects of lncRNA LINC01194 and miR-486-5p on NSCLC cell proliferation and migration invasiveness. For target gene prediction and screening, luciferase reporter assays were used to verify downstream target genes for lncRNA LINC01194 and miR-486-5p. The protein expression of CDK4 was detected using Western blotting. The tumor changes in mice were detected by in vivo experiments in nude mice.
Results: LncRNA LINC01194 was highly expressed in NSCLC tissues and NSCLC lines (A549, H1299, H460 cells, H1975), and lncRNA LINC01194 significantly promoted cell proliferation and migration of NSCLC cells. MiR-486-5p was identified as a potential target for LINC01194, and miR-486-5p was expressed at a low level in NSCLC tissues and NSCLC lines (A549, H1299, H460 cells, H1975). CDK4 was identified as a potential target for miR-486-5p. LncRNA LINC01194 was able to inhibit miR-486-5p expression and upregulate the expression level of CDK4. Finally, the results of in vivo animal models confirmed that lncRNA LINC01194 promoted NSCLC progression by modulating the miR-486-5p/CDK4 axis.
Conclusion: LncRNA LINC01194 promoted the progression of NSCLC by modulating the miR-486-5p/CDK4 axis.
