  1. 1. The expression and regulation of hyaluronan synthases and their role in glycosaminoglycan synthesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Brinck; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; hyaluronan; glycosaminoglycans; CD44; growth factors; UDP-glucose dehydrogenase; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : The glycosaminoglycan hyaluronan is an essential component of the extracellular matrix in all higher organisms, affecting cellular processes such as migration, proliferation and differentiation. Hyaluronan is synthesized by a plasma membrane bound hyaluronan synthase (HAS) which exists in three genetic isoforms. LÄS MER

  2. 2. The role of 1-intergrins in skeletal muscle differentiation and extracellular matrix assembly

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lars Lohikangas; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; β1 Integrins; Matrix Deposition; Skeletal Muscle Cell; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Integrin subunit β1 forms heterodimeric receptors with at least 12 different α-subunits.These integrins are the main cellular receptors for extracellular matrix and they arenecessary for normal development. In this thesis, the effects of lack of integrin subunitβ1 on matrix deposition and on skeletal muscle development were studied. LÄS MER

  3. 3. DNA precursor biosynthesis-allosteric regulation and medical applications

    Detta är en avhandling från Umeå : Medicinsk kemi och biofysik

    Författare :Reza Rofougaran; Anders Hofer; Thomas Borén; Staffan Eriksson; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; DNA biosynthesis; ribonucleotide reductase; allosteric regulation; Trypanosoma brucei; adenosine kinase; nucleoside analogs; mitochondrial DNA; TWINKLE; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Ribonucleotide reductase (RNR) is a key enzyme for de novo dNTP biosynthesis. We have studied nucleotide-dependent oligomerization of the allosterically regulated mammalian RNR using a mass spectrometry–related technique called Gas-phase Electrophoretic Mobility Macromolecule Analysis (GEMMA).

  4. 4. Proteins of the Inter-α-inhibitor Family Biosynthesis, Plasma Clearance and Interaction with Extracellular Matrix Components

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Aneta Kaczmarczyk; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; bikunin; inter-α-inhibitor; pre-α-inhibitor; intracellular processing; plasma clearance; extracellular matrix; binding; collagen; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Bikunin, a chondroitin sulfate-containing protein of 25 kDa, has protease inhibitory activity and occurs in the plasma in free and complexed form. In inter-α-inhibitor (IαI) and pre-a-inhibitor (PαI) it is covalently linked through its chondroitin sulfate (CS) chain to two or one other polypeptide of about 80 kDa – heavy chains 1 and 2 (H1, H2) and heavy chain 3 (H3) – respectively.

    Sammanfattning : Systemic amyloidoses are a group of lethal diseases where proteins aggregate into fibrillar structures, called amyloid fibrils, that deposits throughout the body. Transthyretin (TTR) causes one type of amyloidosis, in which the aggregates mainly infiltrate nervous and cardiac tissue. LÄS MER
