  1. 1. Functions of Heparan Sulfate During Mouse Development : Studies of Mice with Genetically Altered Heparan Sulfate Biosynthesis

    Författare :Maria Ringvall; Lena Kjellén; Erik Forsberg; Ulf Lindahl; Erika Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; embryonic development; gene targeting; lung development; ossification; heparan sulfate; heparin; N-deacetylase N-sulfaotransferase; NDST; proteoglycan; morphogen; biosynthesis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Heparan sulfate (HS) is a ubiquitous polysaccharide on the cell surface and in the extracellular matrix. HS is an important actor in the regulation of cell signaling, especially in the developing embryo. LÄS MER

  3. 2. The Role of Dopamine-Metabolising Enzymes in Renal Sodium Handling. An Experimental Study in vivo

    Författare :Cecilia Odlind; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; dopamine; kidney; sodium; MAO; COMT; rat; mice; RBF; oxygen; renal; L-dopa; DOPAC; entacapone; phenelzine; dopamine receptors; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. LÄS MER

  4. 3. Tumor Necrosis Factor-alpha as a target cytokine in vascular disease

    Författare :Lena Brånén; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; cell replication; Cardiovascular system; Kardiovaskulära systemet; spindle-shaped; epithelioid; smooth muscle cells; periadventitial cuff injury; sTNF-R1; bone marrow transplantation; chimeric fusion protein; atherogenic diet; ApoE; TNF-a; genetically altered mice; en face preparation; atherosclerosis; neointimal hyperplasia;

    Sammanfattning : Inflammation plays an important role in atherosclerosis. One of the most potent pro-inflammatory cytokines is tumor necrosis factor-alpha (TNF-a), a cytokine identified to have a pathogenic role in chronic inflammatory diseases such as rheumatoid arthritis (RA). LÄS MER

  5. 4. Physiological roles of A1 and A2A adenosine receptors : studies using genetically modified mice

    Författare :Jiang-Ning Yang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adenosine receptors; genetically modified mice; preconditioning; tolerance; heart rate; body temperature; locomotor activity; caffeine;

    Sammanfattning : Since adenosine receptors were identified and cloned, their roles in animals and humans have been extensively studied. Because pharmacological tools have limitations, we have used mice in which adenosine receptors have been deleted to further study their roles under physiological and pathophysiological conditions.

  7. 5. Metabolic roles of adenosine : studies using genetically modified mice and transfected cells

    Författare :Stina Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adenosine; A1 receptor; adipocyte; pancreas; skeletal muscle; GHSR1a; caffeine; metabolism and knock out mouse;

    Sammanfattning : The aim of this thesis was to further investigate the metabolic roles of adenosine. The endogenous nucleoside adenosine acts by binding to the four adenosine receptors, A1R, A2AR, A2BR and A3R. The A1R is the adenosine receptor that has been proposed to be the one most involved in metabolism. LÄS MER
