Gastric cancer (GC) is one of the most common cancers with high morbidity and mortality. Familial GC is seen in 10% of cases, and approximately 3% of familial GC cases arise owing to hereditary diffuse gastric cancer (HDGC). CDH1, which encodes the protein E-cadherin, is the only gene whose mutations are associated with HDGC. Screening for the familial GC-predisposing gene has been neglected in...
The two co-activators of the anaphase-promoting complex/cyclosome (APC/C), Cdc20 and Cdh1, facilitate ubiquitination by the core complex, but their role in conferring substrate specificity has been contentious. A new report reveals that Cdc20-bound APC/C initiates the timely proteolysis of many Cdh1 substrates with the exception of the Aurora kinases. Failure to degrade Aurora kinases results i...
DNA double-strand breaks (DSBs) are highly deleterious lesions and their misrepair can promote genomic instability, a hallmark of cancer. DNA-end resection is a cell cycle-regulated mechanism that is required for the faithful repair of DSBs. We recently discovered that the anaphase-promoting complex/cyclosome-Cdh1 (APC/C(Cdh1)) ubiquitin ligase is responsible for the timely degradation of CtBP-...
PURPOSE Recent investigations have demonstrated that hypermethylation is a frequent mechanism for silencing tumor suppressor genes. This is a potentially reversible epigenetic change, and it is the target of a novel class of anticancer compounds with demethylating activity. Better understanding of the clinical implications of hypermethylation will allow the optimal planning of future trials wit...
BACKGROUND Germline mutations in CDH1 are associated with hereditary diffuse gastric cancer; lobular breast cancer also occurs excessively in families with such condition. METHOD To determine if CDH1 is a susceptibility gene for lobular breast cancer in women without a family history of diffuse gastric cancer, germline DNA was analysed for the presence of CDH1 mutations in 318 women with lobu...
BACKGROUND Numerous epidemiological studies have evaluated the association between the CDH1 -160C/A polymorphism and the risk of breast cancers. However, these studies have yielded conflicting results. To derive a more precise estimation of this association, this meta-analysis was conducted. METHODS A comprehensive search using the keywords "CDH1," "E-Cadherin," "polymorphism," "SNP," and "va...
Abstract Introduction Hereditary diffuse gastric cancer is an autosomal inherited syndrome associated with the E-cadherin germline mutations. Different types of CDH1 germline mutations have been reported; the missense alterations are rarely identified when compared with truncating mutations. The identification of missense mutation represents a clinical burden, since its pathogenicity is still u...
The loss of the tumour suppressor E-cadherin (Cdh1) is a key event during tumourigenesis and epithelial-mesenchymal transition (EMT). Transforming growth factor-β (TGFβ) triggers EMT by inducing the expression of non-histone chromatin protein High Mobility Group A2 (HMGA2). We have previously shown that HMGA2, together with Smads, regulate a network of EMT-transcription factors (EMT-TFs) like S...
Background: Anthracosis of the lung occurs due to the deposition of carbon and silica in the mucosa and submucosa, manifested as black lesions. The association of anthracosis with lung cancer has remained to be clearly elucidated The current study aimed to assess the P16, CDH1 and LUNX genes expression level to evaluate the association of anthracotic lesions in the lungs with the occurrence of ...
The catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) is a critical component of the non-homologous end-joining pathway of DNA double-stranded break repair. DNA-PKcs has also been shown recently functioning in mitotic regulation. Here, we report that DNA-PKcs negatively regulates the stability of Cyclin B1 protein through facilitating its ubiquitination mediated by Cdh1 / E 3 ubiquit...
