  1. 11. Roles of Heparan Sulfate in Amyloid-β Pathology and Hypoxia

    Författare :Elina Hjertström; Jin-ping Li; Ulf Lindahl; Sally Stringer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparan sulfate; Alzheimer s disease; Aβ; Proteoglycan; Heparanase; Amyloid; Hypoxia; Cancer; Spalax; Biochemistry; Biokemi; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Heparan sulfate (HS) is a highly sulfated polysaccharide expressed on the cell surface and in the extracellular matrix, interacting with a large number of proteins. HS is implicated in human diseases, including different types of cancer and amyloid diseases such as Alzheimer's disease (AD). LÄS MER

  3. 12. Characterization and Crystallization of Anchorless Glypican-1

    Författare :Gabriel Svensson Birkedal; Glykobiologigruppen; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; S-nitrosylation; nitric oxide; protein stability; protein conformation; X-ray crystallography; calorimetry; spectroscopy; proteoglycan; glypican; heparan sulfate;

    Sammanfattning : Glypicans are cell-surface heparan sulfate proteoglycans that regulate Wnt, Hedgehog, bone morphogenetic protein, and fibroblast growth factor signaling through their heparan sulfate chains. Recent studies have shown that glypican core proteins also have functional roles in growth factor signaling, but biochemical and structural knowledge regarding the core proteins is limited. LÄS MER

  4. 13. Functional and molecular aspects of the glomerular barrier

    Författare :Anna Björnson Granqvist; Göteborgs universitet; []
    Nyckelord :glomerular endothelium; glycocalyx; podocyte; proteoglycan; glycosaminoglycans; nephrotic syndrome;

    Sammanfattning : The kidneys are crucial for maintaining a normal salt-water balance in the body, which is a prerequisite for life. They do that by filtering 180 liters of plasma per day across the highly permselective glomerular barrier and reabsorbing 99 % of the filtrate. LÄS MER

  5. 14. 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

  7. 15. Complement in Disease - Extracellular Proteins as Complement Regulators

    Författare :Kaisa Happonen; Malmö Proteinkemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatoid arthritis; joint disease; Complement; proteoglycan; cancer;

    Sammanfattning : Complement activation occurs during inflammatory joint diseases such as rheumatoid arthritis (RA) and is thought to contribute to the chronic inflammation observed within the joints. Previous studies have shown that certain cartilage components of the small leucine-rich repeat protein (SLRP)-family regulate complement activity, thereby possibly contributing to disease progression.
