  1. 1. Understanding Heparan Sulfate Biosynthesis and Functional Implications of Heparanase

    Författare :Tianyi Song; Dorothe Spillmann; Cathrine Merry; Uppsala universitet; []
    Nyckelord :Heparan sulfate; biosynthesis; heparanase; lipid metabolism; cancer; cell adhesion; apoptosis.; Molekylär medicin;

    Sammanfattning : Heparan sulfate (HS) proteoglycans are present on the plasma membrane of all animal cells studied so far and are a major component of extracellular matrices. Heparanase is an endo-ß-glucuronidase that cleaves HS chains at internally located ß-glucuronidic linkages1. LÄS MER

  3. 2. Implications of Heparan Sulfate and Heparanase in Inflammatory Diseases

    Författare :Andreas Digre; Jin-Ping Li; Lena Kjellén; Liliana Schaefer; Uppsala universitet; []

    Sammanfattning : Heparan sulfate (HS), an unbranched sulfated carbohydrate chain, and the HS-degrading enzyme heparanase play important roles in physiological and pathological processes during all stages of life, from early embryogenesis to ageing. Accumulated information shows that HS and heparanase are involved in inflammatory processes and associated diseases, e. LÄS MER

  4. 3. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation

    Författare :Anjum Riaz; Staffan Johansson; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Integrins; Signal transduction; Protein kinase B; Akt; PI3K; Heparanase; ROS; Mechanosignalling; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Cellforskning; Cell Research;

    Sammanfattning : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

  5. 4. 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

  7. 5. 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; []

    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
