Cervical cancer is a common gynecological malignancy with high morbidity worldwide. MicroRNAs (miRNAs) serve critical roles in cervical cancer progression. Accumulating evidence indicates that miR-873 functions as a tumor suppressor in certain types of cancer. However, the function and mechanism of miR-873 in the progression of cervical cancer have not been completely elucidated. In the present study, the role and mechanism of miR-873 in the proliferation, migration and invasion of cervical cancer cells were investigated. miR-873 expression was markedly decreased in cervical cancer, while glioma-associated oncogene homolog 1 (GLI1) was found to be a direct target of miR-873 by conducting dual-luciferase reporter assays. Furthermore, miR-873 overexpression reduced the expression of GLI1, and decreased the proliferation, metastasis and epithelial-mesenchymal transition of cancer cells. In rescue experiments, overexpression of GLI1 in cervical cancer cells effectively reversed the inhibitory effect induced by miR-873 mimics. Therefore, the results of the present study suggested that miR-873 functions as a tumor suppressor miRNA, and future studies should address its potential application in the treatment of cervical cancer.
