Bleach at the roots of mitotic progression Lim et al. show how hydrogen peroxide at the centrosome spurs cells to advance through mitosis. Cdk1 and regulatory proteins such as cyclin B1, Plk1, and Aurora A cooperate to initiate mitosis. To exit mitosis, cells destroy the regulatory proteins, an effect triggered by the APC/C when it is bound to its coactivator Cdh1. Cdk1 adds phosphates to Cdh1 ...
Nephrolithiasis is a common disorder worldwide. E-cadherin (CDH1) is involved in epithelial cell-cell interactions and plays important roles in the etiology of nephrolithiasis. We hypothesized that variants in the CDH1 gene are associated with risk of nephrolithiasis. In a hospital-based case-control study of 127 nephrolithiasis patients and 152 controls frequency matched by age and sex, we gen...
Cancer cells exhibit two opposing methylation abnormalities: genome-wide hypomethylation and gene promoter hypermethylation. Downregulation of E-cadherin (CDH1) plays a key role in the development of diffuse-type gastric cancer, and DNA methylation is a major cause of the gene's silencing. Hereditary diffuse gastric cancer is caused by germline mutation of CDH1 gene, and DNA methylation frequen...
BACKGROUND Promoter genomic DNA methylation is an important inactivation mechanism of tumor suppressor genes. This genetic-molecular pathway for cancer may separate a subset of patients with different prognoses and eventually different responses to specific therapies. AIM To analyze the methylation pattern of important genes related to different carcinogenic mechanisms in patients with gastri...
OBJECTIVE To find out the effect of miR-544a on the invasion of lung cancer cells and to explore the underlying molecular mechanisms. METHODS Micro-ribonucleic acid (miRNA) expression in two different invasive lung cancer cell lines 95C (low invasive ability) and 95D (high invasive ability) was analyzed by miRNA microarray and real-time quantitative polymerase chain reaction (PCR); miR-544a m...
BACKGROUND Hereditary diffuse gastric cancer (HDGC) is a hereditary autosomal inherited syndrome associated with CDH1 germline mutations. In Brazil, gastrointestinal tumors are among the most prevalent tumor types and constitute a serious public health problem, especially in the northern and northeastern regions. This study aimed to investigate germline mutations, methylation pattern and genomi...
DNA damage triggers cell cycle arrest to provide a time window for DNA repair. Failure of arrest could lead to genomic instability and tumorigenesis. DNA damage-induced G1 arrest is generally achieved by the accumulation of Cyclin-dependent kinase inhibitor 1 (p21). However, p21 is degraded and does not play a role in UV-induced G1 arrest. The mechanism of UV-induced G1 arrest thus remains elus...
Conversion of acetate to methane (aceticlastic methanogenesis) is an ecologically important process carried out exclusively by methanogenic archaea. An important enzyme for this process as well as for methanogenic growth on carbon monoxide is the five-subunit archaeal CO dehydrogenase/acetyl coenzyme A (CoA) synthase multienzyme complex (CODH/ACS) catalyzing both CO oxidation/CO(2) reduction an...
Approximately 10% of gastric cancer cases show familial clustering but only 1-3% of gastric carcinomas arise as a result of inherited gastric cancer predisposition syndromes. Direct proof that Hereditary Gastric Cancer a genetic disease with a germline gene defect has come from the demonstration of co-segregation of germline E-cadherin (CDH1) mutations with early onset diffuse gastric cancer in...
INTRODUCTION Germline mutations in E-cadherin (CDH1) have been reported in families with early onset, diffuse gastric cancer. More recently, mutations in CDH1 have been described in colorectal cancer cell lines. AIMS We have investigated if germline mutations in CDH1 occur among different groups of Korean gastric and colorectal cancer patients, with and without a positive family history. ME...
