    AbstractThe objective of this study was to determine the role of miR-3150b-3p in the cervical cancer (CC) progression. Real-time PCR and western blot analysis were conducted to test the expression of miR-3150b-3p, TNFRSF11a and p38 mitogen-activated protein kinase (MAPK) signaling pathway. The interaction between miR-3150b-3p and TNFRSF11a was verified by luciferase assay. Cell proliferation, migration and invasion were determined by CCK-8, wound healing and Transwell assays. In this study, we showed that miR-3150b-3p was significantly downregulated in CC cell lines. Additionally, miR-3150b-3p markedly attenuated the proliferation, migration and invasion of HeLa and SiHa cells. Moreover, we identified TNFRSF11a to be a novel target of miR-3150b-3p in CC cells. Enforced expression of TNFRSF11a abolished the antitumor effect of miR-3150b-3p. Besides, miR-3150b-3p was involved in the regulation of the p38 MAPK signaling pathway. In conclusion, our data suggested that miR-3150b-3p directly targets TNFRSF11a to inactivate the p38 MAPK signaling pathway, thus implicating miR-3150b-3p in the regulation of CC cell growth.© American Federation for Medical Research 2020.
