Inhibition of cell migration and invasion by miR‑29a‑3p in a colorectal cancer cell line through suppression of CDC42BPA mRNA expression.

The objective of this study was to determine the effect of miR‑29a‑3p inhibitor on the migration and invasion of colorectal cancer cell lines (CRC) and the underlying molecular mechanisms. miR‑29a‑3p was detected using reverse transcription-quantitative polymerase chain reaction (RT‑qPCR) in the CRC cell lines HCT11, CaCo2, HT29, SW480 and SW620. An invasive subpopulation designated SW480‑7 was derived from the parental cell line, detected by Transwell and Transwell Matrigel assays.
