OBJECTIVE: Recent studies have revealed that long noncoding RNAs (lncRNAs) play important roles in the progression of tumorigenesis. Oral squamous cell carcinoma is a disease widely widespread all over the world. The aim of this study was to identify how lncRNA INHBA-AS1 functions in the progression of OSCC.

PATIENTS AND METHODS: LncRNA INHBA-AS1 expression in both OSCC cells and 48 paired tissue samples was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). The function of INHBA-AS1 was identified by the transwell assay, wound healing assay, and proliferation assay in vitro. Meanwhile, the role of INHBA-AS1 was investigated through tumor formation assay in vivo. Furthermore, the underlying mechanism was explored by the luciferase assays and RNA immunoprecipitation assay (RIP).

RESULTS: INHBA-AS1 was highly expressed in OSCC tissues when compared with adjacent tissue samples. The proliferation, invasion, and migration of OSCC cells were significantly inhibited after the knockdown of INHBA-AS1 in vitro. Meanwhile, the knockdown of INHBA-AS1 remarkably inhibited tumor growth and metastasis in vivo. Besides, miR-143-3p was down-regulated after the knockdown of INHBA-AS1 in vitro. The expression of miR-143-3p was negatively correlated with the expression of INHBA-AS1 in OSCC tissues. In addition, miR-143-3p was directly targeted by INHBA-AS1.

CONCLUSIONS: The knockdown of INHBA-AS1 repressed cell migration, invasion, and proliferation in OSCC by sponging miR-143-3p, which might offer a new therapeutic intervention for OSCC patients.
