PURPOSE To identify germ line CDH1 mutations in hereditary diffuse gastric cancer (HDGC) families and develop guidelines for management of at risk individuals. EXPERIMENTAL DESIGN We ascertained 31 HDGC previously unreported families, including 10 isolated early-onset diffuse gastric cancer (DGC) cases. Screening for CDH1 germ line mutations was done by denaturing high-performance liquid chro...
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...
In our recent cancer registry-based study, the incidence of gastric carcinoma was increased up to 5-fold in male relatives of early-onset prostate cancer (PCA) patients. This association may reflect the influence of genetic factors predisposing individuals to both tumor types. Germ-line mutations of the CDH1 gene at 16q have recently been associated with familial gastric cancer. Furthermore, tw...
Absract Gastric cancer is the fourth most common cancer and the second leading cause of cancer death. Most cases are sporadic and only 10% of patients, show familial clustering. Among these patients, 1 to 3 % have hereditary diffuse gastric cancer (HDGC), which is autosomal-dominant and present in younger ages. Mutations in Ecadherin gene CDH1 has been identified in 30 to 50% of patient...
The adhesion of cells to their neighbors determines cellular and tissue morphogenesis and regulates major cellular processes including motility, growth, differentiation, and survival. Cell-cell adherens junctions (AJs), the most common (indeed, essentially ubiquitous) type of intercellular adhesions, are important for maintaining tissue architecture and cell polarity and can limit cell movement...
The anaphase promoting complex (APC) is a ubiquitin ligase that promotes the degradation of cell-cycle regulators by the 26S proteasome. Cdc20 and Cdh1 are WD40-containing APC co-activators that bind destruction boxes (DB) and KEN boxes within substrates to recruit them to the APC for ubiquitination. Acm1 is an APC(Cdh1) inhibitor that utilizes a DB and a KEN box to bind Cdh1 and prevent substr...
H ereditary diffuse gastric cancer (MIM#137215) is an autosomal dominant disease in which gastric cancer develops at a young age. The first report in the medical literature describing familial clustering of gastric cancer was that of Aldred Warthin in 1913, although this family (‘‘family G’’) was subsequently shown to have hereditary non-polyposis colorectal cancer (HNPCC). Further reports of f...
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...
CONTEXT Hereditary diffuse gastric cancer is caused by germline mutations in the epithelial cadherin (CDH1) gene and is characterized by an increased risk for diffuse gastric cancer and lobular breast cancer. OBJECTIVE To determine whether recurring germline CDH1 mutations occurred due to independent mutational events or common ancestry. DESIGN, SETTING, AND PATIENTS Thirty-eight families d...
