miR-214 down-regulates ARL2 and suppresses growth and invasion of cervical cancer cells
Increasing evidence has shown that miRNAs are implicated in carcinogenesis and can function as on-cogenes or tumor suppressor genes in human cancers. In this study, we confirmed that miR-214 is frequently down-regulated in cervical cancer compared with normal cervical tissues. Ectopic expression of miR-214 suppressed proliferation, migration and invasion of HeLa and C33A cervical cancer cells. Bioinformatics analysis revealed that ADP ribosylation factor like 2 (ARL2) was a potential target of miR-214 and was remarkably up-regulated in cervical cancer. Knockdown of ARL2 markedly inhibited cervical cancer cell proliferation, migration and invasion, similarly to over-expression of miR-214, indicating that ARL2 may function as an oncogene in cervical cancer. In conclusion, our study revealed that miR-214 acts as a tumor suppressor via inhibiting proliferation, migration and invasion of cervical cancer cells through targeting ARL2, and that both miR-214 and ARL2 may serve as prognostic or therapeutic targets for cervical cancer.
