Abstract

An increasing number of studies have confirmed that miR‑124 exhibits a suppressive role in glioblastoma, cervical cancer and breast cancer; however, the function of miR‑124 in colorectal cancer (CRC) has not been completely elucidated. In the present study, miR‑124 expression was confirmed by reverse transcription‑quantitative PCR in 80 colorectal tissues and para‑cancerous tissues. The influence of altered miR‑124 expression was analyzed by statistical approaches including Cox multivariate regression analysis and the Kaplan‑Meier method, and the target genes of miR‑124 were confirmed by luciferase reporter assays. Immunohistochemical techniques were also performed in order to measure the expression levels of target proteins. miR‑124 expression was observed to be decreased in colorectal tissue samples, and this phenomenon was correlated with adverse clinical indicators and poor patient survival time. Luciferase reporter assays indicated that miR‑124 directly regulated TNF receptor associated factor 6 (TRAF6) 3'‑untranslated region (UTR). Hence, it was proposed that miR‑124 dysregulation may negatively influence the expression of TRAF6 and therefore serve as a biomarker of epithelial‑mesenchymal transition in CRC tissues. In summary, the present study demonstrated that miR‑124 regulates the expression of TRAF6, and may potentially function as an independent prognostic factor and therapeutic target in patients with CRC.
