The anaphase-promoting complex (APC) regulates cell division in eukaryotes by targeting specific proteins for destruction. APC substrates generally contain one or more short degron sequences that help mediate their recognition and poly-ubiquitination by the APC. The most common and well characterized degrons are the destruction box (D box) and the KEN box. The budding yeast Acm1 protein, an inh...
The anaphase promoting complex/cyclosome (APC/C) is an E3 ligase regulated by Cdh1. Beyond its role in controlling cell cycle progression, APC/C-Cdh1 has been detected in neurons and plays a role in long-lasting synaptic plasticity and long-term memory. Herein, we further examined the role of Cdh1 in synaptic plasticity and memory by generating knockout mice where Cdh1 was conditionally elimina...
Background: Aberrant methylation of cytosine-guanine dinucleotide islands leads to inactivation of tumor suppressor genes in breast cancer. Tumor suppressor genes are unmethylated in normal tissue and often become hypermethylated during tumor formation, leading to gene silencing. We investigated the association between E-cadherin (CDH1) and estrogen receptor-α (ESRα) gene promoter methylation a...
Orofacial clefts (OFC) are among the most common birth defects worldwide. The etiology of non-syndromic OFC is still largely unknown. During embryonic development, the cell adhesion molecule E-cadherin, encoded by CDH1, is highly expressed in the median edge epithelium of the palate. Furthermore, in multiple families with CDH1 mutations, OFC cases are observed. To determine whether CDH1 is a ca...
BACKGROUND AND OBJECTIVES To investigate the clinical value of CDH1 methylation in preoperative peritoneal washes (PPW) from gastric cancer patients. METHODS CDH1 methylation was detected by real-time methylation specific-PCR in tumor tissues and corresponding PPW from 92 gastric cancer patients, gastric mucosa from 40 chronic gastritis patients and 48 normal persons. RESULTS CDH1 methylati...
ell cycle progression is driven by waves of cyclin expression coupled with regulated protein degradation. An essential step for initiating mitosis is the inactivation of proteolysis mediated by the anaphase-promoting complex/cyclosome (APC/C) bound to its regulator Cdh1p/ Hct1p. Yeast APC Cdh1 was proposed previously to be inactivated at Start by G1 cyclin/cyclin-dependent kinase (CDK). Here, w...
This study was designed to investigate the DNA-methylation status of E-cadherin (CDH1) and H-cadherin (CDH13) in serum samples of cervical cancer patients and control patients with no malignant diseases and to evaluate the clinical utility of these markers. DNA-methylation status of CDH1 and CDH13 was analyzed by means of MethyLight-technology in serum samples from 49 cervical cancer patients a...
BACKGROUND DNA methylation has been suggested as a biomarker for early cancer detection and treatment. Varieties of technologies for detecting DNA methylation have been developed, but they are not sufficiently sensitive for use in diagnostic devices. The aim of this study was to determine the suitability of Raman spectroscopy for label-free detection of methylated DNA. METHODS The methylated ...
As a critical ubiquitin ligase, the anaphase-promoting complex/cyclosome (APC/C) governs cell cycle progression, signaling modulation and the pathogenesis of some human diseases. Recent studies implicate APC in maintaining genomic integrity, but the mechanism by which it plays such a role remains largely unknown. We report here that acute UV radiation triggers proteolysis of CDH1, an activator ...
Germline CDH1 mutations confer a high lifetime risk of developing diffuse gastric (DGC) and lobular breast cancer (LBC). A multidisciplinary workshop was organised to discuss genetic testing, surgery, surveillance strategies, pathology reporting and the patient's perspective on multiple aspects, including diet post gastrectomy. The updated guidelines include revised CDH1 testing criteria (takin...
