ARTICLE HIGHLIGHTS
Research background
Population aging has given rise to the incidence rate of colorectal cancer (CRC) worldwide. Better elucidation of the mechanisms underlying the formation and growth of CRC is very helpful for the development of new therapy.
Research motivation
Latest studies have shown that miRNAs generally regulate the expression of oncogenes or tumour suppressor genes and exert integral roles in modulating cancer-related pathways and mediating the formation and progression of CRC. However, whether miR-627-5p is involved in the tumorigenesis of colorectal tumours or not is largely unexplored.
Research objectives
This current study is designed to verify the function of miR-627-5p in colorectal tumorigenesis by targeting Wnt2/β-catenin signalling pathway.
Research methods
The levels of miR-627-5p and Wnt2 were detected in CRC tissues. Functional experiments, including CCK-8, flow cytometry, Matrigel invasion, and scratch assays, were conducted to elucidate the function of miR-627-5p and wnt2 in colorectal tumour cells. Dual luciferase reporter tests were carried out to investigate how miR-627-5p and Wnt2 interact. The critical signalling pathway modulated by miR-627-5p was further identified.
Research results
Wnt2 transcript expression was markedly increased in colorectal tumour tissues and negatively correlated with miR-627-5p level. Upregualtion of miR-627-5p inhibited cancer cells’ abilities to invade growth and migrate by directly restraining Wnt2 expressions. Furthermore, miR-627-5p exerted the suppressive role in CRC via inactivating the Wnt2/β-catenin signalling.
Research conclusions
miR-627-5p restrained the malignant biological properties of CRC cells via directly inhibiting Wnt2 expression to modulate the classical Wnt/β-catenin signalling.
Research perspectives
miRNA-627-5p/Wnt2/β-catenin may have potential therapeutic application for CRC.
