The progression of carcinomas is associated with the loss of epithelial morphology and a concomitant acquisition of a more mesenchymal phenotype, which in turn is thought to contribute to the invasive and/or metastatic behavior of the malignant process. Changes in the expression of cadherins, "cadherin switching," plays a critical role during embryogenesis, particularly in morphogenetic process...

Aim: To evaluate the ability of red and white hibiscus (H) in improving epithelial barrier indomethacin-induced duodenal colonic inflammation, compared with prebiotic to investigate whether and/or can be used as natural like agents. Methods: Histological, histomorphometric, histochemical demonstration for goblets cells mucin intensity. Immunohistochemical COX-2, tight junctions (Claudin-1 E-cad...

Background: Hypertension (HT) promotes structural and functional changes in the cerebral microcirculation that can provoke irreversible cerebrovascular injury, leading to neuronal loss brain atrophy,1 cognitive impairment, vascular dementia,2 Alzheimer’s disease.3 Currently, mechanisms consequences of such remodeling are not fully understood. Transforming growth factor (TGF) is a morphogen reg...

The cadherin gene family encodes calcium-dependent adhesion molecules that promote homophilic interactions among cells. During embryogenesis, differential expression of cadherins can drive morphogenesis by stimulating cell aggregation, defining boundaries between groups of cells and promoting cell migration. In this report, the expression patterns of cadherins were examined by immunocytochemist...

Although reduced levels of the epithelial cell adhesion molecule E-cadherin are often associated with poorly differentiated breast cancers, recent studies show that expression of other cadherins such as N-cadherin, P-cadherin, and the mesenchymal cadherin-11 is actually elevated in invasive breast cancers and cell lines. Cadherin-11 is unique among cadherins in that it exists as two alternative...

BACKGROUND The objective of this study was to assess the potential clinical value of the concentration of soluble salivary E-cadherin (sE-cadherin) compared with the clinical value of the presence of membranous E-cadherin (mE-cadherin) in oral squamous cell carcinoma tumor tissues. MATERIAL AND METHODS Data regarding patient demographics, clinical stage, saliva and tumor tissue samples were c...

Abnormalities in the H-cadherin gene have been described in several human cancers. However, their biological significance remains undetermined. To investigate the role of H-cadherin in non-small cell lung cancer (NSCLC), a chimera H-cadherin-green fluorescent protein (GFP) expressed in Cos-7 cells was used to identify an anti-H- cadherin antibody, HCD-1. Western blot analysis was performed in s...

Vascular endothelial cadherin (VE-cadherin), which belongs to the classical cadherin family, is localized at adherens junctions exclusively in vascular endothelial cells. Biochemical and biomechanical cues regulate the VE-cadherin adhesive potential by triggering the intracellular signals. VE-cadherin-mediated cell adhesion is required for cell survival and endothelial cell deadhesion is requir...

Formation of neural circuits depends on stable contacts between neuronal processes, mediated by interaction of cell adhesion molecules, including N-cadherin. In the present study, we found that activity-dependent dendrite arborization specifically requires N-cadherin-mediated extracellular neuron-neuron interaction, because the enhancement did not occur for neurons cultured in isolation or plat...

The neural cadherin (N-cadherin) is a Ca2+-dependent cell-cell adhesion molecule detected in neural tissues as well as in non-neural tissues. We report here the nucleotide sequence of the chicken N-cadherin cDNA and the deduced amino acid sequence. The sequence data suggest that N-cadherin has one transmembrane domain which divides the molecule into an extracellular and a cytoplasmic domain; th...
