  1. 1. Localization of lipoprotein lipase in mouse pancreas, kidney and placenta : impact of metabolic disturbances on cellular distribution and activity regulation

    Författare :Rakel Nyrén; Gunilla Olivecrona; Paolo Parini; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipoprotein lipase; pancreas; kidney; placenta; angiopoietin-like protein 4; high-fat diet; obesity; mice; PET CT; nutritional status; triglyceride; GPIHBP1; medicinsk och fysiologisk kemi; Medical and Physiological Chemistry;

    Sammanfattning : Lipoprotein lipase (LPL) is the key enzyme for metabolism of triglycerides in plasma lipoproteins. In recent years many new facts about the enzyme and its regulation have been uncovered. The endothelial membrane protein GPIHBP1 translocates LPL through endothelial cells and holds the enzyme in place at the luminal side of the capillary endothelium. LÄS MER

  3. 2. Symbiotic and pathogenic factors in plant-microbe interaction: Structural basis of C-glycoside metabolism and lipoprotein transport in bacteria

    Författare :Valentina Furlanetto; Christina Divne; Mats Sandgren; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plant-Bacteria Interaction; Symbiotic Communication; C-Glycosylated Compounds; Enzymatic Deglycosylation; Pathogenic Interactions; Lipoprotein Localization; Lol System; Biotechnology; Bioteknologi;

    Sammanfattning : The communication between plants and bacteria involves a complex chemical signaling network that mediates responses to various biotic and abiotic stresses, as well as establishing symbiotic relationships between different organisms.The first part of the thesis focuses on a mechanism for symbiotic communication between plants and bacteria and more specifically on how C-glycosylated aromatic polyketide compounds produced by plants can be used as a mechanism for plants to communicate with beneficial bacteria.

  4. 3. Novel factors affecting clearance of triacylglycerol-rich lipoproteins from blood

    Författare :Stefan K Nilsson; Gunilla Olivecrona; Aivar Lookene; Ko Willems van Dijk; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipoprotein; triacylglycerol; apolipoprotein A-V; ANGPTL; Cardiovascular medicine; Kardiovaskulär medicin; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Apolipoprotein (apo) A-V is the most recently discovered member of a protein family responsible for the structure and metabolic fate of plasma lipoproteins. While most of the apolipoproteins are well characterized with regard to structure, interactions and function, the role of apoA-V is not well understood. LÄS MER

  5. 4. Aspects on lipoprotein lipase and atherosclerosis

    Författare :Lucyna Neuger; Philip Barter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physiology; Klinisk fysiologi;

    Sammanfattning : Lipoprotein lipase (LPL) hydrolyses blood lipids at the vascular endothelium. This action makes fatty acids available for tissue metabolic requirements. LPL is anchored to the endothelium by electrostatic forces and may act as a bridge connecting lipoproteins to cell surfaces. LÄS MER

  7. 5. Adrenergic regulation of proliferation and differentiation in brown adipose tissue

    Författare :Stefan Rehnmark; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : Brown adipose tissue constitutes an interesting model for studies of cell proliferation and cellular differentiation. Cold exposure of an animal induces recruitment of the tissue; this is accompanied by a marked increase in the mitogenic activity within the tissue and an increased expression of the genes coding for lipoprotein lipase and the uncoupling protein thermogenin.
