MicroRNA‑142‑3p suppresses cell proliferation, invasion and epithelial‑to‑mesenchymal transition via RAC1‑ERK1/2 signaling in colorectal cancer.

ABSTRACT: Aberrant expression of microRNAs (miRNAs/miRs) is associated with the initiation and progression of colorectal cancer (CRC), but how they regulate colorectal tumorigenesis is still unknown. The present study was designed to investigate the expression profile of miRNAs in human CRC tissues, and to reveal the molecular mechanism of miRNA‑142‑3p in suppressing colon cancer cell proliferation. The expression of miRNA was examined using an Exiqon miRNA array. Bioinformatics was used to predict the target genes of differentially expressed miRNAs and to analyze their biological function in CRC. The effect of miR‑142‑3p in colon cancer cells was evaluated in vitro using cell proliferation, colony formation and Transwell assays. Dual‑luciferase reporter gene assays were performed to investig
