  1. 1. Studies on the Role of UDP-Glucose Dehydrogenase in Polysaccharide Biosynthesis

    Författare :Elisabet Roman; Marion Kusche-Gullberg; Hakon Leffler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; UDP-glucose dehydrogenase; polysaccharide biosynthesis; glycosaminoglycan; A. thaliana; E. coli K5; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Polysaccharides are found in all forms of life and serve diverse purposes. They are enzymatically synthesised from activated monosaccharide precursors, nucleotide sugars. One such nucleotide sugar is UDP-glucuronic acid, which is formed from UDP-glucose by the UDP-glucose dehydrogenase (UGDH) enzyme. LÄS MER

  3. 2. A New Look into Protein C Inhibitor : Posttranslational Modifications and their Functions

    Författare :Wei Sun; Sophia Schedin Weiss; Hakon Leffler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Protein C inhibitor; posttranslational modifications; N-glycan; O-glycan; mass spectrometry; factor Xa; thrombin; prostate specific antigen; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : The influences of posttranslational modifications on the functions of the versatile serpin protein C inhibitor (PCI) were studied. PCI is a serine protease inhibitor that is expressed in many tissues and secreted to various fluids in human, including blood plasma, seminal plasma, and urine. LÄS MER

  4. 3. Design and Synthesis of Galectin Inhibitors

    Författare :Pernilla Sörme; Barbro Kahl Knutson; U Wellmar; B-G Magnusson; Hakon Leffler; Ulf Nilsson; Yuan C. Lee; Reiko T. Lee; Centrum för analys och syntes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parallel Synthesis; Inhibitors; Biomedicinska vetenskaper allmänt ; General biomedical sciences; Carbohydrates; Galectins;

    Sammanfattning : Galectins, a lectin family, have shown binding affinities towards b-galactosides. Galectins have been proposed to be involved in a wide range of functions like for example, cell growth, adhesion, migration, chemo taxis and apoptosis. They have also been associated with various cancer types. LÄS MER

  5. 4. Perturbation of the epithelial barrier by enteric pathogens

    Författare :Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Nyckelord :enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Sammanfattning : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. LÄS MER
