Abstract:

Objective: To investigate the expression of microRNA (miRNA)-337-3p in oral squamous cell carcinoma (OSCC) and its clinical significance. Methods: The expression of miRNA-337-3p in OSCC cancer and paracancerous tissue of 20 OSCC patients was determined, and the correlation of miRNA-337-3p expression with clinical-pathological parameter was analyzed. Scratch test was performed to detect the effect of miRNA-337-3p on migration ability of OSCC cell line HN30 cells, and the possible molecular mechanism was explored. Results: Expression of miRNA-337-3p in OSCC was significantly lower than that in paracancerous tissue(P<0.000 1), and was correlated significantly with the status of lymph node metastasis (P<0.05). Patients with lymph node metastasis (N1+N2) had a lower expression level of miRNA-337-3p than those without lymph node metastasis (N0). Overexpression of miRNA-337-3p in HN30 cells inhibited cell migration, whereas suppression of miRNA-337-3p led to increase of cell migration. miRNA-337-3p could inhibit the expression of matrix metalloproteinase-14 (MMP-14). Conclusions: miRNA-337-3p plays a suppressive role in OSCC, inhibitingthe invasion and metastasis of OSCC cells, and is expected to be used as a biomarker for assessing the invasion and metastasis of OSCC and helping the monitoring of prognosis.
