Original Article


Oral squamous cell carcinoma (OSCC) characterized with invasive growth, local metastasis and later stage diagnosis was a common malignancy in head and neck region. The aim of this study was to explore the relationship between miR-182-5p and OSCC, which will contribute to find potential biomarker for OSCC metastasis. MiR-182-5p expression level was detected by the quantitative real-time PCR (qRT-PCR). Cell migration and invasion ability were examined by scratch and transwell assay. Loss-of function together with luciferase reporter assay were used to verify the miR-182-5p modulated OSCC cells migration and metastasis was mediated by MTSS1. The expression of MTSS1 protein was examined by western blotting. MiR-182-5p up-regulated in OSCC, was involved in the migration and invasion of OSCC and the increased miR-182-5p expression was correlated with lower OSCC differentiation grade, higher T and N stage. Bioinformatics analysis predicted MTSS1 gene was a potential target of miR-182-5p. Following co-transfection, qRT-PCR, luciferase activities assay and western blotting confirmed that MTSS1 gene was a direct target of miR-182-5p and silence of MTSS1 could reverse the effects of miR-182-5p on OSCC migration and invasion. MiR-182-5p was up-regulated in OSCC and the ability of miR-182-5p to promote MTSS1 repression may precipitate in the OSCC through bypassing cell migration and invasion control.
