OBJECTIVE: In recent years, long non-coding RNAs (lncRNAs) have emerged for regulating the development, as well as progression in colorectal cancer (CRC), which assists in finding new targets for CRC treatment. A previous study indicated that INHBA-AS1 promotes oral squamous cell progression by sponging miR-143-3p. However, the exact function possessed by lncRNA INHBA-AS1 in CRC development remains unclear.

PATIENTS AND METHODS: The expression level of INHBA-AS1 in CRC tissues and cell lines was determined by qRT-PCR. The functional role of INHBA-AS1 in CRC was investigated by a series of in vitro assays. RNA immunoprecipitation (RIP), bioinformatics analysis was utilized to explore the potential mechanisms of INHBA-AS1.

RESULTS: The present study identified INHBA-AS1 as a kind of lncRNA with high expression in CRC tissues and cells. Functionally, NHBA-AS1 downregulation in CRC cells suppressed CRC cell proliferation as well as colony formability. Mechanistically, INHBA-AS1/miR-422a/AKT1 established the ceRNA network to regulate MMP-2, -7, -9 expressions that participated the modulation of CRC progression.

CONCLUSIONS: In summary, LncRNA INHBA-AS1 contributes to CRC progression through AKT1 pathway, and provides a new mechanism to regulate CRC development, as well as a potential target for treating CRC.
