A class of highly sialylated glycoproteins with very large mucin-like domains that protrude high above the plasma membrane have been shown to strongly reduce cellular adhesion. In normal epithelial cells, where the expression is restricted to the luminal side of the cell, these molecules may prevent inadvertent closing of the lumen as a result of weak,(More)
Episialin (MUC1) is a transmembrane molecule with a large mucin-like extracellular domain protruding high above the cell surface. The molecule is located at the apical side of most glandular epithelial cells, whereas in carcinoma cells it is often present at the entire surface and it is frequently expressed in abnormally large quantities. We have previously(More)
Episialin is a mucin-type glycoprotein present at the luminal side of most glandular epithelial cells. We have isolated cDNA clones encoding episialin and determined the structure of the gene. The gene encodes a transmembrane protein which consists of, for the greater part, tandem repeats of 20 amino acids. The number of these repeats varies between 40 and(More)
Using specimens from a population-based case control study among women ages 18 to 44 years in western Washington, we assessed the relationship between carriership of a genetic clotting factor II variant (20210 G-->A) and myocardial infarction (MI). The factor II variant was previously shown to be present in 1% to 2% of the population, to increase the levels(More)
Recently, it has been proposed that abnormalities in coagulation and fibrinolysis contribute to the development of preeclampsia by increasing the thrombotic tendency. This hypothesis was tested in women who have had preeclampsia (cases) compared with matched controls. Polymorphisms in the thrombophilia genes [plasminogen activator inhibitor type 1 [PAI-1(More)
ABO blood group and more recently high von Willebrand factor (VWF) and factor (F)VIII levels have been associated with thrombotic disease. An excess of non-O blood group has long been recognized in patients with ischemic heart disease [1] and venous thrombosis [2]. In 1995, we demonstrated that nonO blood group, high VWF levels and high FVIII levels all(More)
BACKGROUND Binding of protein C (PC) to the endothelial cell PC receptor (EPCR) stimulates PC activation by increasing the affinity of PC for the thrombin-thrombomodulin complex. A soluble form of this receptor (sEPCR) circulates in plasma and inhibits both PC activation and APC anticoagulant activity. OBJECTIVES The aim of this study was to investigate(More)
The episialin gene (MUC1) encodes an epithelial mucin containing a variable number of repeats with a length of twenty amino acids, resulting in many different alleles that can be subdivided into two size classes. The episialin pre-mRNA uses either one of two neighbouring splice acceptor sites for exon 2, which mainly encodes the repeats. Using the genetic(More)
High factor VIII levels increase the risk of venous thromboembolism, but the mechanisms that cause high factor VIII levels are unclear. In 301 thrombosis patients and 301 matched healthy controls, factor VIII antigen (VIII:Ag) levels > or = 150 IU/dl increased the thrombosis risk more than fivefold. We investigated whether high factor VIII:Ag levels result(More)
Episialin is a mucin-like molecule located at the apical surface of most glandular epithelial cells. It is present at increased levels in carcinomas, where the molecule is often distributed over the entire cell surface. We have simulated this overproduction of episialin by transfecting a normal mammary epithelial cell line and a melanoma cell line with(More)
