Homophilic binding of E-cadherins through their ectodomains is fundamental to epithelial cell-cell adhesion. Despite this, E-cadherin ectodomains have evolved differently in the vertebrate and hexapod lineages. Of the five rod-like, tandemly aligned extracellular cadherin domains (ECs) of vertebrate E-cadherin, the tip EC plays a pivotal role in binding interactions. Comparatively, the N-termin...

BACKGROUND Many studies have investigated the prognostic role of E-cadherin in patients with NSCLC; however, the result still remains inconclusive. An up-to data system review and meta-analysis was necessary to give a comprehensive evaluation of prognostic role of E-cadherin in NSCLC. METHODS Eligible studies were searched in Pubmed, Embase and Web of Science databases. The inclusion criteria...

A loss or reduced expression of E-cadherin, the main cell-to-cell adhesion molecule, correlates with distant metastasis in various cancers. Recent studies have reported a close correlation between the expression of E-cadherin and that of S100A4, calcium-binding protein. In this study, we investigated the expression of E-cadherin and S100A4 status in relation to the clinicopathological parameter...

OBJECTIVE To investigate the promoter methylation status of the E-cadherin gene in non-small cell lung cancer (NSCLC) and its association with clinical pathological parameters, and to explore the relationship between downregulation of E-cadherin gene expression and the methylation status of its promoter region. METHODS Nested methylation-specific PCR was performed to examine CpG methylation w...

β-Catenin is a central player in Wnt signaling, and activation of Wnt signaling is associated with cancer development. E-cadherin in complex with β-catenin mediates cell-cell adhesion, which suppresses β-catenin-dependent Wnt signaling. Recently, a tumor-suppressive role for E-cadherin has been reconsidered, as re-expression of E-cadherin was reported to enhance the metastatic potential of mali...

E-cadherin is a well-known mediator of cell-cell adherens junctions. However, many other functions of E-cadherin have been reported. Collectively, the available data suggest that E-cadherin may also act as a gene transcriptional regulator. Here, evidence supporting this claim is reviewed, and possible mechanisms of action are discussed. E-cadherin has been shown to modulate the activity of seve...

Reduced expression of E-cadherin was observed in renal cell carcinoma (RCC). However, its potential clinical value and correlation with WNT/β-catenin signaling in RCC progression was still unclear. Immunohistochemical staining was performed in RCC tissue microarray to examine the expression status and prognosis value of E-cadherin and β-catenin. The potential role of E-cadherin in β-catenin tra...

E-cadherin is an essential adhesion protein as well as a tumor suppressor that is silenced in many cancers. Its adhesion-dependent regulation of signaling has not been elucidated. We report that E-cadherin can negatively regulate, in an adhesion-dependent manner, the ligand-dependent activation of divergent classes of receptor tyrosine kinases (RTKs), by inhibiting their ligand-dependent activa...

A fundamental question in stem cell biology concerns the regulatory strategies that control the choice between multipotency and differentiation. Drosophila blood progenitors or prohemocytes exhibit key stem cell characteristics, including multipotency, quiescence, and niche dependence. As a result, studies of Drosophila hematopoiesis have provided important insights into the molecular mechanism...

The interaction of connexin 43 and E-cadherin may play an important role in carcinogenesis and malignant behaviour of tumours. In this study, we examined the relationship between connexin 43 and E-cadherin in human non-small cell lung cancers (NSCLC). Expression levels of connexin 43 and E-cadherin were examined in 107 NSCLC specimens by immunohistochemistry. The connexin 43 gene was transfecte...
