The poor prognosis of colorectal cancer (CRC) contributes to a yearly increase in CRC mortality, while microRNAs (miRNAs) were found to play a regulatory function in diversiform cancers, including CRC. The objective of this research was to evaluate the clinical value and possible regulatory mechanisms of miR-767-5p in CRC. The expression level of miR-767-5p in CRC tissues and cells was examined. The Kaplan-Meier curve was utilized to analyse the function of miR-767-5p in CRC prognosis. The independent prognostic factors in CRC were assessed by a multivariate COX regression analysis. Additionally, the regulatory mechanism of miR-767-5p in CRC was determined through an in vitro cell experiment. The miR-767-5p expression was down-regulated in CRC tumour tissues and CRC cells. Indicators such as tumour differentiation, TNM, LNM and miR-767-5p were identified as independent prognostic factors for a poor CRC prognosis. The regulatory relationship between miR-767-5p and nuclear factor I A (NFIA) was verified by the dual-luciferase reporter assay, and the NFIA expression level was significantly suppressed by over-expressed miR-767-5p. The proliferation, migration and invasion of CRC cells were inhibited by over-expressing miR-767-5p, while the inhibition effect could be reversed by over-expressing NFIA. The over-expressed miR-767-5p could serve as a tumour suppressor to inhibit the progression of CRC by suppressing the expression level of NFIA.
