BACKGROUND A disintegrin and metalloproteinase with thrombospondin motifs 1, Adamts-1, is important for the development and function of the kidney. Mice lacking this protein present with renal lesions comprising enlarged calyces, and reduced cortex and medulla layers. Our current findings are consistent with the defect occurring due to a developmental dysgenesis. METHODS We generated Adamts-1...

ADAMTS-1 (a disintegrin and metalloproteinase with thrombospondin motifs), the first described member of the ADAMTS family, is differentially expressed in various tumors. However, its exact role in tumor development and progression is still unclear. The aim of this study was to investigate the effects of ADAMTS-1 transfection in a bronchial epithelial tumor cell line (BZR) and its potential to ...

BACKGROUND AND OBJECTIVES Autoantibodies inactivating the von Willebrand factor (VWF) cleaving protease, ADAMTS-13, are among the most frequent causes of thrombotic thrombocytopenic purpura (TTP). We evaluated whether or not ADAMTS-13 deficiency and autoantibodies inactivating the protease prevalent in patients with the prototypic autoimmune diseases systemic lupus erythematosus (SLE) and syste...

Human umbilical vein endothelial cell (HUVEC)–released ADAMTS-13 (a disintegrin and metalloprotease with thrombospondin repeats) and HUVEC-secreted von Willebrand factor (VWF) strings were investigated under static conditions that allow the accumulation and analysis of ADAMTS-13. The latter was released constitutively from HUVECs and cleaved the secreted and cell-anchored VWF strings progressiv...

Interleukin-1 (IL-1β) is the main proinflammatory cytokine stimulant of cartilagedegeneration in arthritis. Aggrecanases (ADAMTS or A Disintegrin And Metalloproteinase with ThromboSpondin motifs) are enzymes implicated in tissue remodeling and cleavage of aggrecan core protein between Glu-Ala, a major structural protein of cartilage extracellular matrix giving its characteristic compressive sti...

Abstract von Willebrand factor (VWF) is a large adhesive multimeric protein involved in hemostasis. The larger the size (or number of VWF multimers), greater functionality protein. A deficiency or defect can lead to disease (VWD) and cause bleeding. Conversely, an increase may create environment that promotes thrombosis. ADAMS-13 (a disintegrin metalloproteinase with thrombospondin type 1 motif...

PURPOSE The in vitro study suggested that proline to serine polymorphism in codon 475 (C1423T) of the A Disintegrin and Metalloprotease with ThromboSpondin type 1 repeats-13 (ADAMTS-13) gene is related to reduced activity of ADAMTS-13. In this study, the frequency of the Pro475Ser polymorphism in Koreans was studied and plasma ADAMTS-13 activity was measured to find out whether this polymorphis...

Changes in plasma von Willebrand factor concentration (VWF:Ag) and ADAMTS-13 activity (the metalloprotease that cleaves VWF physiologically) have been reported in several cardiovascular disorders with prognostic implications. We therefore determined the level of these proteins in the plasma of children with cyanotic congenital heart disease (CCHD) undergoing surgical treatment. Forty-eight chil...

OBJECTIVE We investigated the potential role of ADAMTS-1 (a disintegrin and metalloprotease with thrombospondin motif type I) in atherogenesis. METHODS AND RESULTS ADAMTS-1 is expressed at the highest levels in the aorta when compared with other human tissues examined. Immunolocalization studies in human aorta and coronary artery indicate that ADAMTS-1 expression is mainly seen at low levels ...
