Abstract

Purpose

E-cadherin, a transmembrane glycoprotein mediating Ca²⁺-independent homotypic cell–cell adhesion in epithelial cell, plays an essential role in metastasis. It has been postulated that E-cadherin downregulation is a crucial mechanism in the pathogenesis of endometriosis. To evaluate the effect on the cell behavior after knockdown of E-cadherin gene (CDH1) in cultured human endometrial epithelial cells (EECs) isolated from normal endometrium.

Methods

EECs were isolated from the endometrial tissues of fertile woman who underwent total hysterectomy due to cervical intraepithelial neoplasia III. CDH1 expression was knocked down by small hairpin RNA. The EECs transfected with empty vector served as control. Transwell assay was used to test EECs migration or invasion. qRT-PCR and western blot were used to detect mRNA and protein levels.

Results

The results showed that knockdown of E-cadherin expression can increase cell migration and invasion, and up-regulate mRNA and protein levels of β-catenin, cyclinD1, and c-myc.

Conclusions

Down-regulation of E-cadherin expression may activate the Wnt/β-catenin pathway in endometrial cells, which may together participate in the occurrence of endometriosis.
