Hereditary diffuse gastric cancer (HDGC) is an inherited form of gastric cancer that carries a poor prognosis. Most HDGCs are caused by an autosomal dominant genetic mutation in the CDH1 gene, which carries a 70%-80% lifetime risk of gastric cancer. Given its submucosal origin, endoscopic surveillance is an unreliable means of early detection, and prophylactic gastrectomy is recommended for CDH...
In ECAD application areas there is a real need for electrical circuit modelling and analy sis tools at an intermediate level between analogue and state based simulators Numerical tools do not capture the abstractions valued by engineers and logical functional models do not maintain su cient a nities with the electrical properties of a system This paper examines the nature of this problem and th...
BACKGROUND Approximately one third of the hereditary diffuse gastric cancer (HDGC) families carry germline mutations in the E-cadherin gene (CDH1). Risk prediction in members of families with this rare but deadly cancer could be improved by the identification of additional HDGC genes in non-CDH1 families. METHODS Affected individuals from 22 CDH1 mutation-negative families were screened for g...
Metastases are involved in most cancer deaths. Evidence has suggested that cancer cell detachment from primary tumors might occur largely via the mechanism of epithelial-mesenchymal transition (EMT) activated by epigenetic events, but data addressing other possible triggers of detachment, particularly genetic mutations, have been limited. Using the Profile study of cancer genomics at Dana-Farbe...
Studies of brain-specific kinase 2 (BRSK2), an AMP-activated protein kinase (AMPK)-related kinase, and its homologs suggest that they are multifunctional regulators of cell-cycle progression. BRSK2, which contains a ubiquitin-associated (UBA) domain, is polyubiquitinated in cells. However, the regulatory mechanisms and exact biological function of BRSK2 remain unclear. Herein, we show that BRSK...
E-cadherin is a member of the classical cadherin family and is known to be involved in cell-cell adhesion and the adhesion-dependent morphogenesis of various tissues. We isolated a zebrafish mutant (cdh1(rk3)) that has a mutation in the e-cadherin/cdh1 gene. The mutation rk3 is a hypomorphic allele, and the homozygous mutant embryos displayed variable phenotypes in gastrulation and tissue morph...
NF-κB is dually involved in neurogenesis and brain pathology. Here, we addressed its role in adult axoneogenesis by generating mutations of RelA (p65) and p50 (also known as NFKB1) heterodimers of canonical NF-κB. In addition to RelA activation in astrocytes, optic nerve axonotmesis caused a hitherto unrecognized induction of RelA in growth-inhibitory oligodendrocytes. Intraretinally, RelA was ...
Cell cycle dysregulation upon human cytomegalovirus (HCMV) infection of human fibroblasts is associated with the inactivation of the anaphase-promoting complex (APC), a multisubunit E3 ubiquitin ligase, and accumulation of its substrates. Here, we have further elucidated the mechanism(s) by which HCMV-induced inactivation of the APC occurs. Our results show that Cdh1 accumulates in a phosphoryl...
BACKGROUND We investigated whether an endogastric capsule (EC) may be a valuable tool for collecting DNA from exfoliated cells from the gastric mucosa and for carrying out an analysis of promoter methylation status of the E-cadherin (CDH1) gene in poorly differentiated, diffuse gastric cancer (DGC). MATERIAL AND METHODS Consecutive patients with a confirmed diagnosis of poorly differentiated ...
