  1. 41. Cellular regulation of heparan sulfate structure and function

    Författare :Fariba Safaiyan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Heparan sulfate; structure; biosynthesis; sulfation; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Heparan sulfate (HS) is a sulfated glycosaminoglycan found on cell surfaces and in the extracellular matrix as HS proteoglycans. HS is synthesized as a polymer of alternating glucuronic acid and N-acetylglucosamine units. LÄS MER

  3. 42. Intracellular processing of pre-a-inhibitor

    Författare :Maria Thuveson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; pre-alpha-inhibitor; heavy chain 3; bikunin; intracellular processing; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Pre-α-inhibitor (PαI) is a plasma protein consisting of a 25 and a 75 kDa polypeptide: bikunin and heavy chain 3 (H3), respectively. Both these polypeptides are made by hepatocytes and while passing through the Golgi complex, bikunin, which carries a chondroitin sulfate chain, becomes covalently linked to the C-terminal amino acid residue of H3 via its polysaccharide.

  4. 43. Role of Heparan Sulfate Structure in FGF-Receptor Interactions and Signaling

    Författare :Nadja Jastrebova; Dorothe Spillmann; Ulf Lindahl; John T. Gallagher; Uppsala universitet; []
    Nyckelord :Biochemistry; heparan sulfate; oligosaccharide; fibroblast growth factor; fibroblast growth factor signaling; Biokemi;

    Sammanfattning : Heparan sulfate (HS) belongs to the glycosaminoglycan family of polysaccharides and is found attached to protein cores on cell surfaces and in the extracellular matrix. The HS backbone consists of alternating hexuronic acid and glucosamine units and undergoes a number of modification reactions creating HS chains with alternating highly and low modified domains, where high degree of modification correlates with high negative charge.

  5. 44. Decoding Heparan Sulfate

    Författare :Johan Kreuger; John T. Gallager; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Heparan sulfate; fibroblast growth factor; receptor; endostatin; angiogenesis; interaction; sequence; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Heparan sulfate (HS) is a polysaccharide of glycosaminoglycan type composed of alternating hexuronic acid [either glucuronic acid (GlcA) or iduronic acid (IdoA)] and glucosamine (GlcN) units that can be sulfated in various positions. HS binds to a large number of proteins and these interactions promote many biological processes, including cell adhesion and growth factor signaling. LÄS MER

  7. 45. 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
