Construction of interference vector targeting Ep-CAM gene and its effects on colorectal cancer cell proliferation.

ABSTRACT:

Background

Prior study indicates that abnormal protein expression and functional changes in the development and progression of colorectal cancer is related to gene expression. The aim of this study was to construct an interference plasmid targeting the Ep-CAM gene and to investigate its effects on the proliferation of colorectal cancer cells.

Methods

In this study, HT-29 and HCT-116 colorectal cancer cell lines were selected as cell models. The double-stranded micro (mi)RNA oligo was inserted into the pcDNATM6.2-GW/EmGFPmiR vector, which is an expression of miRNA. Lipofectamine™ 2000 was used to transfer plasmid into the empty plasmid group (transfected pcDNATM6.2-GW/EmGFPmiR-neg) and the interference group (transfected pcDNATM6.2-GW/EmGFPmiR-Ep-CAM-1), respectively.
