The function of cadherin cell adhesion molecules is thought to be regulated by a group of cytoplasmic proteins, including alpha-catenin. We identified a subtype of alpha-catenin, termed alpha N-catenin, which is associated with N-cadherin and expressed mainly in the nervous system. cDNA transfection experiments showed that alpha N-catenin can also bind with(More)
Two distinct calcium-sensitive cell-cell adhesion molecules were identified in human epithelial tissues and carcinomas using two monoclonal antibodies raised against vulvar epidermoid carcinoma A-431 and human mammary carcinoma MCF-7 and selected on the basis of their activities to disrupt cell-cell adhesion. In immunoblot analysis, these antibodies,(More)
P-cadherin is a subclass of Ca2+-dependent cell-cell adhesion molecules present in mouse placenta, where its localization suggests a function of connecting the embryo to the uterus (Nose, A., and M. Takeichi. 1986. J. Cell Biol. 103:2649-2658). We recently identified a human cadherin detected by an mAb capable of disrupting cell-cell adhesion of A-431(More)
Epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), and human epidermal growth factor receptor 2 (HER2) have been considered as potential therapeutic targets in cholangiocarcinoma, but no studies have yet clarified the clinicopathological or prognostic significance of these molecules. Immunohistochemical expression of these(More)
During embryogenesis, smooth muscle cells of the gut differentiate from mesenchymal cells derived from splanchnic mesoderm. We have isolated a gene involved in the differentiation of smooth muscle cells in the gut using differential display between the chicken proventriculus in which the smooth muscle layer develops poorly and the gizzard in which smooth(More)
We examined 28 cases of surgically resected gastric cancer, excluding the diffuse type, for loss of heterozygosity (LOH) on 12 chromosomal arms using polymorphic DNA markers. LOH on chromosome 18q was detected in 61% (14 of 23) of the cases by the probes OLVIIA8, OLVIIE10, p15-65, SAM 1.1, and OS-4, and a putative common region showing LOH included the(More)
To clarify the course of adenomatous hyperplasia (AH) of the liver, 17 patients with 20 biopsy-proven AH nodules were followed clinically for 1-5 years. At the initial biopsy the mean nodular diameter was 10 (SD 4) mm and the relative cellularity [( mean cellularity of AH divided by mean parenchymal cellularity] x 100) 141 (27). The criteria for diagnosis(More)
BACKGROUND AND PURPOSE Visual defect due to optic radiation injury is a complication of temporal lobectomy for temporal epilepsy. To investigate whether diffusion tensor imaging can delineate the changes in optic radiations after lobectomy, we evaluated parameters on tensor images for optic radiations and correlated them with visual defect. METHODS We(More)
Loss of heterozygosity (LOH) on chromosomes 2q, 9p, 18q, and 22q frequently occurs in advanced non-small cell lung carcinoma (NSCLC). The association of p53 mutations with prognosis is still unclear in NSCLC. Therefore, we investigated the prognostic significance of allelic imbalances (AI) on these chromosomes and p53 mutations in 108 cases of stage I NSCLC(More)
It has long been a practical problem for surgical pathologists to distinguish mesothelium from epithelium in order to make a positive diagnosis of mesothelioma. In this study, we developed a new monoclonal antibody, designated MS-2761 (IgG1, k), against cultured non-neoplastic mesothelial cells. Immunohistochemistry and slot-blot analysis revealed that this(More)
