  1. 16. A Genetic Survey of the Pathogenic Parasite Trypanosoma cruzi

    Författare :Anh-Nhi Tran; Lena Åslund; John Kelly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Trypanosoma cruzi; Chagas ; gene discovery; EST; sequencing; DGC3; repeats; gene family; CL Brener; trypanothione synthetase; TcTRS locus; alleles; polymorphism; RNA-binding protein; TcPTB; stage-specific expression; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Sammanfattning : Trypanosoma cruzi, the causative agent of Chagas´ disease, is an evolutionarily ancient species with distinct biological and immunological characteristics. A fundamental understanding of the basic biology of the parasite is necessary in order to develop reliable therapeutic and prophylactic agents against T. cruzi. We have, as a part of the T. LÄS MER

  3. 17. Gene-environment interactions for arsenic metabolism and metal-related oxidatively generated DNA damage

    Författare :Karin Engström; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AS3MT; methylation; polymorphism; 8-oxodG;

    Sammanfattning : Over 100 million people around the world are exposed to high concentrations of arsenic (As) in drinking water, associated with a number of adverse health effects such as skin, lung and bladder cancer, vascular diseases and diabetes. In humans, As is metabolized via alternating reduction and methylation reactions, from inorganic As (iAs) into monomethylated (MMA) and dimethylated As (DMA). LÄS MER

  4. 18. Cloning, Expression, Pharmacological Characterization and Anatomical Distribution of Melanocortin Receptors in an Evolutionary Perspective

    Författare :Aneta I. Ringholm; Helgi B. Schiöth; Dan Larhammar; Björn Olde; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; evolution; melanocortin; MSH; pharmacology; genome duplication; tetraploidization; zebrafish; spiny dogfish; chicken; GPCR; polymorphism; pigmentation; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : The melanocortin (MC) receptors are G-protein coupled receptors thatparticipate in several important physiological functions such as the regulation of the energy balance. This thesis focuses on the evolutionary aspect of the MC receptors and their pharmacology.One MC4 receptor and two MC5 receptor subtypes were found in a teleost fish, zebrafish. LÄS MER

  5. 19. Plasminogen Activator Inhibitor 1 in Platelets - Studies of Synthesis, Activity, and Glycosylation Patterns

    Författare :Helén Brogren; Göteborgs universitet; []
    Nyckelord :PAI-1; platelets; plasma; fibrinolysis; synthesis; polymorphism; glycosylation; activity; platelet mRNA;

    Sammanfattning : Plasminogen activator inhibitor 1 (PAI-1) is the main physiological inhibitor of tissue-type plasminogen activator. Thus PAI-1 plays an important role in decreasing the fibrinolytic activity in human blood. PAI-1 is present in high concentrations in platelets and also in low concentrations in plasma, but the source of plasma PAI-1 is not known. LÄS MER

  7. 20. Gene conversion of the mouse MHC class II

    Författare :Kari Högstrand; Ulf Gyllensten; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MHC; H2; gene conversion; evolution; polymorphism; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : The major histocompatibility complex (MHC) is the most polymorphic vertebrate gene loci known to exist. Gene products of the MHC are responsible for presentation of antigen derived peptides to T cells of the immune system, which thereby become activated and involved in the elimination of particles recognised as non-self.
