DNA cytosine-5 methylation plays a vital role in regulating the expression of E-cadherin, which is encoded by the CDH1 gene. In this study, we characterised the DNA methylation and expression pattern of CDH1 in an extravillous trophoblast cell line (HTR-8/SVneo) and two trophoblast cell lines -- JEG-3 and JAR. Promoter hypermethylation with reduced E-cadherin expression in HTR-8/SVneo cells and...
The products of the E-cadherin (CDH1), H-cadherin (CDH13) and a disintegrin and metalloproteinase with thrombospondin motif 18 (ADAMTS18) genes are proteins displaying structural features and functions on the cell surface membrane, and have been reported to be involved in cancer progression. Using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and methylation-specific PC...
BACKGROUND Mutations in the E-cadherin (CDH1) gene are a well documented cause of hereditary diffuse gastric cancer (HDGC). Development of evidence based guidelines for CDH1 screening for HDGC have been complicated by its rarity, variable penetrance, and lack of founder mutations. METHODS Forty three new gastric cancer (GC) families were ascertained from multiple sources. In 42 of these famil...
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...
In cell cultures, the dispersed phenotype is indicative of the migratory ability. Here we characterized Sal-like 4 (SALL4) as a dispersion factor in basal-like breast cancer. Our shRNA-mediated SALL4 knockdown system and SALL4 overexpression system revealed that SALL4 suppresses the expression of adhesion gene CDH1, and positively regulates the CDH1 suppressor ZEB1. Cell behavior analyses showe...
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...
Introduction Successful completion of chromosome segregation and cytokinesis requires the coordinated activation and inactivation of numerous mitotic regulators. Inactivation is largely brought about by ubiquitindependent proteolysis, with the relevant E3 ubiquitin ligase being the anaphase promoting complex, or cyclosome (APC/C) (Irniger et al., 1995; King et al., 1995; Sudakin et al., 1995). ...
Receptor-associated protein 80 (RAP80) is a component of the BRCA1-A complex that recruits BRCA1 to DNA damage sites in the DNA damage-induced ubiquitin signaling pathway. RAP80-depleted cells showed defective G(2)-M phase checkpoint control. In this study, we show that RAP80 protein levels fluctuate during the cell cycle. Its expression level peaked in the G(2) phase and declined during mitosi...
BACKGROUND In eukaryotic cells, a specialized proteolysis machinery that targets proteins containing destruction-box sequences for degradation and that uses a ubiquitin ligase known as the anaphase-promoting complex/cyclosome (APC) plays a key role in the regulation of mitosis. APC-dependent proteolysis triggers the separation of sister chromatids at the metaphase-anaphase transition and the de...
Within the mammalian ovary, oocytes remain arrested at G2 for several years. Then a peri-ovulatory hormonal cue triggers meiotic resumption by releasing an inhibitory phosphorylation on the kinase Cdk1. G2 arrest, however, also requires control in the concentrations of the Cdk1-binding partner cyclin B1, a process achieved by anaphase-promoting complex (APC(Cdh1)) activity, which ubiquitylates ...
