Single nucleotide polymorphisms (SNPs) occurring in noncoding sequences have largely been ignored in genome-wide association studies (GWAS). Yet, amounting evidence suggests that many noncoding SNPs especially those that are in the vicinity of protein coding genes play important roles in shaping chromatin structure and regulate gene expression and, as such, are implicated in a wide variety of d...

abstract background: gastric cancer is one of the most common cancers in the world especially in iran. there are many genomic and molecular factors that cause gastric cancer to occur. also, many markers that associate with tumor invasiveness have been known.  e-cadherin is a calcium- mediated cell adhesion molecule. in some studies, abnormal expression of e-cadherin has been seen in gastric car...

PURPOSE Loss of intercellular adhesion and increased cell motility promote tumor cell invasion and spreading. In bladder cancer, loss or reduced E-cadherin expression has been associated with poor survival, and aberrant expression of N-cadherin has been associated with the invasive phenotype of bladder carcinoma cells. The purpose of this study was to investigate whether N-cadherin expression w...

conclusions abnormal e-cadherin expression is a common phenomenon in gastric adenocarcinoma. the study showed a significant correlation between abnormal e-cadherin expression and tumor grade and regional lymph node involvement; so, abnormal e-cadherin expression may be used as a predictive factor for tumor invasiveness in gastric adenocarcinoma. materials and methods a historical cohort survey ...

Hypermethylation in the E-cadherin promoter region and expression of the transcription factor Snail were analyzed in 41 cases of esophageal squamous cell carcinoma (ESCC) and paired normal squamous epithelium by methylation-specific polymerase chain reaction (PCR) and reverse transcription–polymerase chain reaction (RT-PCR) to clarify the mechanism regulating E-cadherin deletion; 93 cases of ES...

BACKGROUND Ulcerative colitis associated colorectal cancer (UCACRC) has several distinctive clinicopathological and genetic features which differ from sporadic colorectal cancer (SCRC). Hypermethylation of the E-cadherin gene (CDH1) has not been described previously in colorectal cancer. AIMS A panel of SCRC and UCACRC were investigated for mutations in CDH1, and for hypermethylation of the p...

Losing the E-cadherin plays an important role in the metastasis of cancer. The regulation of the expression of E-cadherin is unclear. Circadian rhythm alteration is associated with the pathogenesis of a number of cancers. This study aims to investigate the role of one of the circadian proteins, period-2 (Per2) in repressing the expression of E-cadherin in esophageal cancer (esophageal cancer). ...

A centrifugal force-based adhesion assay has been used to quantitatively examine the kinetics of formation of cell-cell contacts mediated specifically by expression of E-cadherin under the control of a glucocorticoid-inducible promoter in mouse fibroblasts. Analysis of cells expressing maximal or minimal levels of E-cadherin showed that the strength of E-cadherin-mediated adhesion developed in ...

Nervous system morphogenesis is characterized by extensive interactions between individual axon growth cones and their cellular environments. Selective cell adhesion is one mechanism by which the growth of an axon can be modulated, and members of the classic cadherin group of cell adhesion molecules have been shown to play a role in this process in both vertebrates and Drosophila. In Drosophila...
