Abstract

A large number of microRNAs (miRNAs) are aberrantly expressed in cervical cancer and play crucial roles in the onset and progression of cervical cancer by acting as either an oncogene or a tumor suppressor. Therefore, investigation of the expression, biological roles, and underlying mechanisms of miRNAs in cervical cancer might provide valuable therapeutic targets in the treatment for patients with this disease. In this study, miRNA- 377 (miR-377) was downregulated in cervical cancer tissues and cell lines. Decreased miR-377 expression was strongly correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis, and distant metastasis in patients with cervical cancer. Enhanced expression of miR-377 prohibited cell proliferation and invasion in cervical cancer. Bioinformatics analysis predicted that zinc finger E-boxbinding homeobox 2 (ZEB2) was a potential target of miR-377. Subsequent experiments confirmed that ZEB2 is a direct target gene of miR-377 in cervical cancer. In addition, ZEB2 was overexpressed in cervical cancer tissues and was inversely related with miR-377 levels. Furthermore, the suppressive effects of miR-377 on cervical cancer proliferation and invasion were rescued by restored ZEB2 expression. Overall, our findings indicated that miR-377 decreases proliferation and invasion of cervical cancer cells by directly targeting ZEB2 and provides novel evidence of miR-377 as a novel therapeutic strategy for the therapy of patients with this malignancy.
