OBJECTIVE: MicroRNAs (miRNAs) have been demonstrated to be involved in the pathogenesis of various human cancers, including oral squamous cell carcinoma (OSCC). Here, we designed this study to explore the potential effect of miR-1290 on tumorigenesis of OSCC.

PATIENTS AND METHODS: The expressions of miR-1290 and cyclin G2 (CCNG2) in OSCC were observed by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Dual-Luciferase Reporter Assay was performed to confirm the relationship between miR-1290 and CCNG2. The functions of miR-1290 and CCNG2 were analyzed using transwell assay. The Western blot analysis was used to detect epithelial-mesenchymal transition (EMT).

RESULTS: Upregulation of miR-1290 and downregulation of CCNG2 were identified in OSCC. And upregulation of miR-1290 was associated with clinicopathological characteristics and poor prognosis in OSCC patients. Moreover, the downregulation of miR-1290 inhibited cell metastasis and EMT in OSCC cells. Furthermore, CCNG2 was a direct target of miR-1290. Its expression was inversely regulated by miR-1290 in OSCC cells. At the same time, the suppressive effect of CCNG2 was observed in OSCC. Furthermore, overexpression of CCNG2 weakened the promoted effect of miR-1290 on cell metastasis in OSCC.

CONCLUSIONS: MiR-1290 promoted cell metastasis and EMT, inhibiting CCNG2 expression in OSCC.
