  2. 6. Molecular Phylogenetics of Mammals

    Author : Morgan Kullberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; EST; divergence times; phylogenomics; phylogenetic reconstruction; Mammals; Eutheria; cytogenetics; Genetik; cytogenetik;

    Abstract : In this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. READ MORE

  4. 7. Nora virus as a model to study persistent infection in Drosophila melanogaster

    Author : Mazen Habayeb; Dan Hultmark; Joachim De Miranda; Molecular Biology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nora virus; Drosophial; persistence; transmission; RNAi; capsid proteins; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; molekylärbiologi; Molecular Biology;

    Abstract : Drosophila melanogaster has been widely used as a model organism to study the immune responses against bacteria, fungi, parasites and viruses. Here, I present a D. melanogaster virus as a model to study persistent virus infections. I have discovered and characterized the Nora virus, a small picorna-like RNA virus able to persistently infect D. READ MORE

  5. 8. Molecular dissection of B-lymphocyte signalling using expression profiling

    Author : Jessica M Lindvall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Btk; B-lymphocyte; gene expression profiling; signal transduction;

    Abstract : Gene expression profiling and bioinformatics have emerged into playing a large and diverse role in many aspects of both the clinical and molecular research. These two approaches have in this thesis work been used in combination in order to shed light to the role of Bruton's tyrosine kinase (Btk) in B-lymphocyte development and signal transduction.

  6. 9. Molecular mechanisms involved in glioma cell interactions in vitro and studies of PDGF B transcript variants

    Author : Susanne Heller; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Tumor heterogeneity; glioma; differential display; PDGF B; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Glioblastoma multiforme is a malignant brain tumor characterized by heterogeneity.Interactions between heterogeneous tumor cells are supposed to affect the behavior of awhole tumor cell population. READ MORE

  7. 10. Analysis of genomic data as an approach to understanding migration in song birds

    Author : John Boss; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Many species of birds migrate every year thousands of kilometers, relying on sight, memory, magnetic sensors and instincts to find their way across continents. Many juvenile birds travel complicated migration routes without the guidance of more experienced adults. READ MORE
