Abstract:
Objective: To investigate the effect of lncRNA SNHG11 on the proliferation, invasion and migration of non-small cell lung cancer (NSCLC) A549 cells and its possible mechanisms. Methods: qPCR was used to detect the levels of lncRNA SNHG11 and miR- 193a-5p in human embryonic lung cells (HEL-1) and lung cancer cells (A549, H1299, and HCC827). A549 cells were transfected with SNHG11 small interfering RNA (si-SNHG11), miR-193a mimic or miR-193a inhibitor. The proliferation of A549 cells was detected by CCK-8 assay, migration and invasion of A549 cells were detected by Wound healing and Transwell assay, the protein expression of Ki67 and Cyclin D1 was determined by Western blot, and the targeting relationship between lncRNA SNHG11 and miR-193a-5p was verified by Dual-luciferase reporter experiment. Results: Compared with HEL-1 cells, the expression level of lncRNA SNHG11 was significantly increased while the expression of miR-193a-5p was decreased in lung cancer A549, H1299 and HCC827 cells (all P<0.05). Silencing lncRNA SNHG11 inhibited the proliferation, migration and invasion of A549 cells and reduced the protein expression of Ki67 and Cyclin D1 (all P<0.05). Over-expression of miR-193a-5p inhibited the proliferation, migration and invasion of A549 cells (all P<0.05). lncRNA SNHG11 could targetedly adsorb miR-193a-5p. miR-139a-5p inhibition could partially reverse the effect of silencing lncRNA SNHG11 on the proliferation, invasion and migration of A549 cells (all P<0.05). Conclusion: lncRNA SNHG11 promotes the proliferation, invasion and migration of NSCLC cells by adsorbing miR-193a-5p.
