  1. 26. EXT Proteins in Heparan Sulfate Biosynthesis

    Författare :Marta Busse; Marion Kusche-Gullberg; Tarja Kinnunen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Heparan sulfate (HS) is a long unbranched polysaccharide composed of alternating glucosamine and hexuronic (glucuronic or iduronic) acid residues. Modification by sulfate groups in various positions generates a highly heterogeneous molecule. LÄS MER

  3. 27. In Vitro Studies of the Substrate Specificities of Heparan Sulfate 2-O- and 6-O-sulfotransferases

    Författare :Emanuel Smeds; Marion Kusche-Gullberg; Ulf Lindahl; Catherine L. R. Merry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; heparin; sulfotransferase; 2-O-sulfotransferase; 6-O-sulfotransferase; polysaccharide biosynthesis; glycosaminoglycan; O-sulfotransferase; proteoglycan; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Heparan sulfate (HS), a linear negatively charged polysaccharide located at the cell surface and in the extracellular matrix, interacts with, and thereby regulates the functions of numerous proteins. HS-protein interactions depend on the fine structure of HS, especially its sulfation pattern. LÄS MER

  4. 28. Polysaccharides in Alzheimer's disease and inflammation-associated amyloidosis

    Författare :Birgitta Lindahl; Uppsala universitet; []
    Nyckelord :Medical sciences; Alzheimer s disease; amyloid; heparan sulfate; keratan sulfate; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : Amyloidosis is a term for diseases that share a common feature: the extracellular deposition of amyloid fibrils, that consist of a single protein prone to aggregate. Polysaccharides (glycos-aminoglycans), especially heparan sulfate, are significant components of all types of amyloid deposits. LÄS MER

  5. 29. Aspects on dermatan sulfate metabolism

    Författare :Erik Eklund; Matrixbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; Clinical biology; iduronic acid; galactosaminoglycan; Dermatan sulfate; biosynthesis;

    Sammanfattning : The functions of proteoglycans often depend on the fine structure of the covalently attached glycosaminoglycan (GAG) side-chains. The process leading to the mature GAG is complex and involves a multitude of different enzymatic steps. LÄS MER

  7. 30. Syndecan - Regulation and Function of its Glycosaminoglycan Chains

    Författare :Anna S. Eriksson; Dorothe Spillmann; Catherine Merry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heparan sulfate; chondroitin sulfate; integrin; cell motility; fibroblast growth factor signaling; pharyngeal cartilage; biosynthesis regulation; Medical Science; Medicinsk vetenskap;

    Sammanfattning : The cell surface is an active area where extracellular molecules meet their receptors and affect the cellular fate by inducing for example cell proliferation and adhesion. Syndecans and integrins are two transmembrane molecules that have been suggested to fine-tune these activities, possibly in cooperation. Syndecans are proteoglycans, i.e. LÄS MER
