miR-24-3p Promotes Cell Proliferation, Migration, and Invasion of Human Cervical Cancer Cells through/via Targeting AMOTL2 and Attenuating the YAP/Hippo Pathway

Abstract BackgroundmiR-24-3p promotes the development of the majority of malignancies.However, its function in cervical cancer is not clearly elucidated so far.MethodsIn this study, cell proliferation, migration, and invasion were measured by the CCK8 and transwell assays. Bioinformatic methods were used to predict the target genes of miR-24-3p, verifying by luciferase reporter assay and western blotting. The target genes set was also used for KEGG pathway enrichment analysis. ResultsThen we obsrved higher miR-24-3p level in cervical cancer cells and faster growth of tumor in a xenograft model. The function assays demonstrated that miR-24-3p promoted proliferation, migration, and invasion of cervical cancer cells in vitro. It was confirmed that miR-24-3p directly targeted AMOTL2 and the recovery of AMOTL2 reversed the function of miR-24-3p in cervical cancer cell line CaSki. Besides, miR-24-3p suppressed the Hippo signaling pathway in CaSki and SiHa cells. ConclusionsIn conclusion, our results reminded that miR-24-3p could boost the migration and proliferation of cervical cancer cells via down-regulating AMOTL2 and attenuating YAP/Hippo signaling pathway activity.
