  2. 1. Glypican-1: Structural and functional analysis of the N-glycosylated human protein

    Author : Wael Awad Abdelhady; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteoglycans; glypicans; glypican-1; heparan sulphate; N-glycosylation; exostosin-proteins; X-ray crystallography; crystal dehydration; diffraction anisotropy; Small angle X-ray scattering SAXS9; protein spectroscopy;

    Abstract : Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediating the signalling of various growth factors.

  4. 2. Characterization and Crystallization of Anchorless Glypican-1

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

    Abstract : 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.

  5. 3. Involvement of Heparan Sulphate Biosynthesis and Turnover in Cell Proliferation. A Novel Role for Nitric Oxide in Recycling of Heparan Sulphate Proteoglycans

    Author : Katrin Mani; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitrite.; nitric oxide; growth-inhibition; xyloside; glypican; heparan sulphate; Proteoglycan; glycosaminoglycan; Clinical biology; Klinisk biologi;

    Abstract : The present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. READ MORE

  6. 4. Interactions of Prion Proteins and PrP-derived Peptides in Scrapie infection

    Author : Kajsa Löfgren Söderberg; Astrid Gräslund; Marcus Fändrich; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spongiform encephalopathy; Creutzfeldt-Jakob disease; Amyloidosis; Neurodegeneration; Cell penetrating peptide; Protein Transduction Domain; Heparan sulfate; Proteoglycan; Glypican; Src family kinase; Fyn; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Prion diseases are fatal and incurable spongiform encephalopathies that occur amongst mammals. The central pathological event is the misfolding of the cellular prion protein (PrPC) into an amyloid, neurotoxic isoform called scrapie (PrPSc). PrPSc is the main, or sole, constituent of infectious prions. READ MORE

  7. 5. The uterine proteoglycan expression in pregnancy and labor

    Author : Ann Hjelm Cluff; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Labor; dysfunctional labor; heparan sulphate proteoglycans; syndecans; glypicans; perlecans; decorin; connexin 43; gap junctions; myometrial contractions;

    Abstract : Objective: Protracted labor is a common clinical problem causing maternal and fetal complications. It is the leading indication for caesarean sections throughout the world, and emphasizes our need to be able to control labor. READ MORE
