E-cadherin gene is often termed a "metastasis suppressor" gene because the E-cadherin protein can suppress tumor cell invasion and metastasis. Inactivation of the E-cadherin gene occurs in undifferentiated solid tumors by both genetic and epigenetic mechanisms; however, the role of E-cadherin in hematologic malignancies is only now being recognized. E-cadherin expression is essential for erythr...

objective: the appropriate interaction between a blastocyst and the endometrium is essential for successful implantation. numerous factors, including hormone receptors (progesterone receptor), cytokines [leukemia inhibitory factors (lif)], and adherence molecules such as e-cadherin are involved in the cross-talk that occurs between the embryo and endometrium. studies show that a lack of these g...

BACKGROUND AND OBJECTIVE Colon cancer is one of the most common malignant tumors, and its pathogenesis is not fully understood. Transcriptional silencing by DNA methylation is believed to be an important mechanism of carcinogenesis. E-cadherin can suppress tumor cell invasion and metastasis, and is considered as an invasion/metastasis suppressor gene. Inactivation of E-cadherin gene often occur...

background: the current study investigated the possible role of the cell cycle regulator, cyclin-dependent kinases regulatory subunit-2; the angiogenic factor, plateletderived endothelial cell growth factor; and the cell adhesive molecule, neural cadherin, as prognostic factors in schistosomal and non-schistosomal-associated urothelial carcinomas. we also investigated the possible correlation b...

Head and neck squamous cell carcinoma (HNSCC) represents a large majority of cancers arising from the head and neck, especially the oral cavity. Despite advances in therapy, the five-year survival rate remains low due to the number of patients presenting advanced stages of the disease. The role of epithelial-mesenchymal transition (EMT) in tumorigenesis in HNSCC remains unexplored. The current ...

Loss of E-cadherin expression and gain of N-cadherin expression ('cadherin switch') is shown to be characteristic in epithelial to mesenchymal transition (EMT), a mechanism associated with cancer progression. Furthermore, the prognostic role of P-cadherin in different cancers is controversial. The aim of this study was to evaluate the prognostic significance of 'cadherin switch' on the gene exp...

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...

PURPOSE Our recent reports indicated that the molecular changes of pterygia are similar to tumor cells. We believe that pterygia may have a similar mechanism in oncogenesis. Many studies have revealed that E-cadherin associated protein expression decreases in many tumors and pterygia. E-cadherin may be a marker for both tumor metastasis and prognosis. However, no studies have examined the reaso...

Cadherin-mediated cell-cell adhesion plays important roles in mouse embryonic development, and changes in cadherin expression are often linked to morphogenetic events. For proper embryonic development and organ formation, the expression of E-cadherin must be tightly regulated. Dysregulated expression during tumorigenesis confers invasiveness and metastasis. Except for the E-box motifs in the E-...

Cyclooxygenases (COXs) are enzymes that catalyze the formation of prostaglandins. Prostaglandins a class lipid mediators can promote inflammation, pain, and fever as well maintain variety normal physiological functions. exist in two forms, COX-1 COX-2, both which localized to luminal membrane endoplasmic reticulum. COX-2 expression is usually induced response certain stimuli, such infection. Ho...
