OBJECTIVE: This study aims to explore the role of microRNA-320c (miR-320c) in regulating biological behaviors of cervical cancer and the potential mechanism, thus providing experimental references for developing therapeutic target of cervical cancer.

PATIENTS AND METHODS: Differential expressions of miR-320c in cervical cancer samples and normal cervical tissues were determined. Potential association between miR-320c level and clinical characteristics of cervical cancer patients was analyzed. After overexpression of miR-320c, migratory potential changes in HeLa, and C33-A cells were examined. At last, target gene binding to miR-320c was predicted online and its involvement in the malignant development of cervical cancer was finally explored.

RESULTS: It was found that miR-320c was lowly expressed in cervical cancer tissues. Compared with cervical cancer patients with high expression of miR-320c, those with low expression had higher rates of lymphatic metastasis and distant metastasis. Besides, the overexpression of miR-320c markedly inhibited migratory potential in HeLa and C33-A cells. GABRP was verified to be the target gene binding to miR-320c. Notably, GABRP was able to reverse the role of miR-320c in regulating migratory potential in cervical cancer.

CONCLUSIONS: MiR-320c is capable of inhibiting migratory potential in cervical cancer by targeting GABRP, which may be utilized as a therapeutic target of cervical cancer.
