  1. 16. Enzymes involved in heparan sulfate chain elongation : Function of a novel family of tumor suppressors?

    Författare :Thomas Lind; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; biosynthesis; glycosyltransferase; EXT1; EXT2; UDP-glucosedehydrogenase; KfiC; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Heparan sulfate (HS) is a glycosaminoglycan associated with many physiological functions such as regulation of growth factor action and cell adhesion. The HS polysaccharide is synthesized by alternating addition of D-glucuronic acid (GlcA) and N-acetyl-D-glucosamine (GlcNAc) units from the corresponding UDP-sugar precursors. LÄS MER

  3. 17. 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

  4. 18. Regulation of Heparan Sulfate 6-O-Sulfation Patterns

    Författare :Anh-Tri Do; Marion Kusche-Gullberg; Ulf Lindahl; Malcolm Lyon; Uppsala universitet; []
    Nyckelord :Biochemistry; Heparan Sulfate; Biosynthesis; 6-O-sulfation; 6-O-sulfotransferases; 6-O-endosulfatases; Nematostella; Biokemi;

    Sammanfattning : Heparan sulfates (HSs) are linear, negatively charged polysaccharides composed of alternating hexuronic acid (glucuronic acid or iduronic acid) and glucosamine residues that can be substituted to varying degrees with sulfate groups. HS, localized in the extracellular matrix and on the surface of most cells, interacts with a large number of proteins. LÄS MER

  5. 19. N-Sulfation and Polymerization in Heparan Sulfate Biosynthesis

    Författare :Jenny Presto; Lena Kjellén; Gunnar Pejler; Anders Malmström; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; Heparan sulfate; N-deacetylase N-sulfotransferase; NDST; EXT1; EXT2; Biosynthesis; Cell- och molekylärbiologi;

    Sammanfattning : Heparan sulfate (HS) is a glycosaminoglycan present in all cell types covalently attached to core proteins forming proteoglycans. HS interacts with different proteins and thereby affects a variety of processes. LÄS MER

  7. 20. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis

    Författare :Tahira Batool; Jin-Ping Li; Aristidis Moustakas; Liliana Schaefer; Ingvar Ferby; Michael Welsh; Anders Malmström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparanase; Glucuronyl-C5 epimerase; Heparan Sulfate; Heparin; Lung Cancer; Cancer cell Singling; TGF-Beta; BMP; VEGF; Notch Signaling; Tumor growth; Metastasis; embryonic development; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. LÄS MER
