PURPOSE This study aims to identify downstream target genes regulated by lysine-specific demethylase 1 (LSD1) in colon cancer cells and investigate the molecular mechanisms of LSD1 influencing invasion and metastasis of colon cancer. METHOD We obtained the expression changes of downstream target genes regulated by small-interfering RNA-LSD1 and LSD1-overexpression via gene expression profilin...
Cadherins are cell-to-cell adhesion molecules that play an important role in the establishment of adherent-type junctions by mediating calcium-dependent cellular interactions. The CDH1 gene encodes the transmembrane glycoprotein E-cadherin which is important in maintaining homophilic cell-cell adhesion in epithelial tissues. E-cadherin interacts with catenin proteins to maintain tissue architec...
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 ...
BACKGROUND Findings related to the influence of the -160C → A promoter polymorphism and haplotypes of the E-cadherin (CDH1) gene have not been consistent in previous studies regarding the risk for sporadic gastric cancer. Investigators in most previous studies detected those genotypes using restriction fragment length polymorphism analysis. Therefore, we conducted a case-control study to invest...
BACKGROUND Epithelial-to-mesenchymal transition (EMT) is a phenomenon that allows the conversion of adherent epithelial cells to a mesenchymal cell phenotype, which enhances migratory capacity and invasiveness. Recent studies have suggested that EMT contributes to the pathogenesis of ulcerative colitis (UC). We investigated the promoter DNA methylation status of EMT-related genes in the colonic...
The anaphase-promoting complex/cyclosome (APC/C) is a ubiquitin ligase with essential functions in mitosis, meiosis, and G1 phase of the cell cycle. APC/C recognizes substrates via coactivator proteins such as Cdh1, and bound substrates are ubiquitinated by E2 enzymes that interact with a hetero-dimer of the RING subunit Apc11 and the cullin Apc2. We have obtained three-dimensional (3D) models ...
The endocycle represents an alternative cell cycle that is activated in various developmental processes, including placental formation, Drosophila oogenesis, and leaf development. In endocycling cells, mitotic cell cycle exit is followed by successive doublings of the DNA content, resulting in polyploidy. The timing of endocycle onset is crucial for correct development, because polyploidization...
BACKGROUND Hereditary diffuse gastric carcinomas (HDGCs) are particularly troubling because of autosomal dominant heritance, high penetrance, early age of onset, and a lack of effective treatment once symptomatic. HDGC is further complicated by difficulty of effective screening. Gastrectomy provides definitive treatment for CDH1 mutation-positive patients. Attempting to minimize the morbidity a...
microRNAs (miRNAs) regulate gene expression at the post-transcriptional level and play important roles in tumor initiation and progression. Recently, we examined the global miRNA expression profile of esophageal squamous cell carcinoma (ESCC) and demonstrated that miR-92a was highly expressed in tumor tissues. In this study, we found that the up-regulation of miR-92a was significantly correlate...
Proteolysis triggered by the anaphase-promoting complex (APC) is needed for sister chromatid separation and the exit from mitosis. APC is a ubiquitin ligase whose activity is tightly controlled during the cell cycle. To identify factors involved in the regulation of APC-mediated proteolysis, a Saccharomyces cerevisiae GAL-cDNA library was screened for genes whose overexpression prevented degrad...
