  1. 1. Regulation of adenovirus alternative pre-mRNA splicing : Functional characterization of exonic and intronic splicing enhancer elements

    Författare :Bai-Gong Yue; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; pre-mRNA splicing; splicing enhancer; MLTU; L1; SR protein; ASF SF2; E. coli; phosphorylation; dephosphorylation; Biokemi; Biochemistry; Biokemi; mikrobiologi; Microbiology;

    Sammanfattning : Pre-mRNA splicing and alternative pre-mRNA splicing are key regulatory steps controlling geneexpression in higher eukaryotes. The work in this thesis was focused on a characterization of thesignificance of exonic and intronic splicing enhancer elements for pre-mRNA splicing. LÄS MER

  2. 2. Studies on the Molecular Biology of the Mouse Pneumotropic Polyomavirus

    Författare :Shouting Zhang; Kristina Dörries; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; murine pneumotropic virus; Kilham mouse polyomavirus; large T antigen; enhancer; regulatory region rearrangement; gene expression regulation; DNA replication; transposable elements; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Murine Pneumotropic Virus (MPtV), in contrast to the other MurinePolyomavirus (MPyV), appears to be non-tumourigenic in its natural host. Instead, MPtV causes acute pneumonia and can serve as a model in studies of polyomavirus-induced disease. In initial experiments, MPtV large T-antigen (LT) was expressed in a heterologous system.

  3. 3. The Carboxyl Ester Lipase Gene. Organization, Evolution and Transcriptional Regulation in Exocrine Pancreas and Mammary Gland

    Författare :Ulf Lidberg; Chalmers University of Technology; []
    Nyckelord :NF-1; pseudogene; evolution; pancreas; carboxyl ester lipase; regulation; duplication; promoter; enhancer; locus; gene structure; mammary gland;

    Sammanfattning : The carboxyl ester lipase (CEL) is an important enzyme for the intestinal absorption of dietary lipids. In humans the gene is highly expressed in exocrine pancreas and in the lactating mammary gland. It is secreted in an inactive form and becomes activated by bile salts in the intestine. LÄS MER

  4. 4. Genetic variation at the human tissue-type plasminogen activator locus

    Författare :Per Ladenvall; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue-type plasminogen activator; single-nucleotide polymorphism; vascular release; myocardial infarction; enhancer; Sp1.;

    Sammanfattning : Tissue-type plasminogen activator (tPA) is the key initiator of intravascular fibrinolysis. Family studies suggest that tPA release is regulated by hereditary factors. LÄS MER

  5. 5. Studies on the Polymorphism and Transcriptional Regulation of the ABO and P1PK Histo-blood Group Genes

    Författare :Britt Thuresson; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood group; ABO; A4GALT; P1PK; Gene regulation; Enhancer;

    Sammanfattning : Antigens of the clinically important ABO and P1PK blood group systems are carbohydrate structures. Thus the underlying genes do not encode antigens directly but glycosyltransferases that add specific sugar molecules to selected precursor chains. LÄS MER
