CCK-8 method and Transwell test were used to identify the effects of lncRNA NORAD on the proliferation and invasion in NSCLC. Target gene prediction and screening and luciferase reporter assay was used to verify downstream target genes of lncRNA NORAD. The expressions of PI3K, AKT, and mTOR proteins were detected by Western blot.Results: Compared with normal tissues and cells, the expressions of lncRNA NORAD in cancer tissues and cells were significantly higher. Compared with normal cells, the expression of miR-520a-3p in cells was considerably lower. LncRNA NORAD could accelerate the growth and metastasis of NSCLC in vitro and in vivo. Luciferase reporter assay results indicated that miR-520a-3p was a downstream target gene of lncRNA NORAD. Further findings showed that lncRNA NORAD might bind to miR-520a-3p, thereby affecting the PI3k/Akt/mTOR signaling pathway.Conclusion: LncRNA NORAD can regulate the proliferation of NSCLC by regulating miR-520a-3p/PI3k/Akt/mTOR signaling pathway, thus promoting the occurrence and development of NSCLC.Keywords: non-small cell lung cancer, lncRNA NORAD, miR-520a-3p, PI3k/Akt/mTOR, proliferation
