E(pithelial)-cadherin and N(eural)-cadherin are transmembrane cell-cell adhesion molecules, belonging to the subfamily of classical cadherins. The expression of E- and N-cadherin is spatiotemporally regulated and associated with a variety of normal morphogenetic events. The expression of E- and N- cadherin is also involved in carcinogenesis. E-cadherin functions as a tumor-suppressor. N-cadheri...

Considerable evidence now exists to support an important role for the E-cadherin-mediated cell-cell adhesion pathway as a suppressor of the invasive phenotype in adenocarcinoma cells. Previous studies have found that this pathway is frequently aberrant in prostate cancers, particularly those that are likely to metastasize. In this study, we report on the effects of re-establishment of this path...

A mature columnar intestinal epithelium develops late in embryogenesis and is maintained throughout the life of the organism. Although the mechanisms driving intestine-specific gene expression have been well studied, those promoting the acquisition of cell-cell junctions, columnar morphogenesis, and polarization have been less studied. The Cdx homeodomain transcription factors (Cdx1 and Cdx2) r...

A new regulatory loop in cancer-cell invasion the epithelial-to-mesenchymal transition (EMt) converts epithelial cells into mesenchymal cells that are able to invade and migrate. in the context of cancer pathogenesis, the EMt contributes to meta-static progression (thiery, 2002; acloque et al, 2008). one of the characteristics of EMt is the functional loss of E-cadherin, which is crucial for th...

AIM to investigate the expression of proliferating cell nuclear antigen (PCNA) and E-cadherin in gastric carcinoma and to analyze their clinical significance. METHODS A total of 146 patients were selected for this study, including 38 patients with intestinal metaplasia, 42 with dysplasia, and 66 with primary gastric cancer. In addition, 40 patients with normal gastric tissues were selected as...

BACKGROUND Hypermethylation is studied as a new, relevant mechanism for silencing tumor suppressor genes. It is a potentially reversible epigenetic change and it is the target of novel anticancer compounds with demethylating activity. In this perspective, we investigated E-cadherin gene (CDH1) promoter hypermethylation in gastric carcinomas and its correlation with E-cadherin protein expression...

E-cadherin is a cell to cell adhesion molecule which acts as a suppressor of metastasis. This study examined the effect of y-litmlmir acid (GLA), a n-(>polyunsaturated fatty acid, on the expression of E-cadherin in human cancer cells. Western blotting studies demonstrated that treatment of cells with GLA for 24 h increased the expression of E-cadherin in lung, colon, breast, melanoma, and liver...

E-cadherin, a calcium-dependent cell-cell adhesion molecule, plays a key role in the maintenance of tissue integrity. The function of this molecule is partly mediated by alpha-/beta-/gamma-catenin. Loss or dysfunction of E-cadherin is associated with an invasive phenotype. We analyzed the expression of E-cadherin and beta-catenin in human lung cancer to determine the relationship to clinicopath...

Dysadherin, a cancer-associated membrane glycoprotein, down-regulates E-cadherin and promotes cancer metastasis. This study examined the role of dysadherin in breast cancer progression. Expression of dysadherin was found to be highest in breast cancer cell lines and tumors that lacked the estrogen receptor (ER). Knockdown of dysadherin caused increased association of E-cadherin with the actin c...
