  1. 21. Comparative Genomics in Diplomonads : Lifestyle Variations Revealed at Genetic Level

    Författare :Feifei Xu; Jan O. Andersson; Staffan G. Svärd; Matt Berriman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; comparative genomics; Giardia intestinalis; Spironucleus salmonicida; Trepomonas; diplomonad; intestinal parasite; free-living; sexual recombination; hydrogenosome; horizontal gene transfer; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. LÄS MER

  3. 22. Analyses of genomic and gene expression signatures

    Författare :Rickard Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Microarray; comparative genomics; differential gene expression; cell lines; computational biology;

    Sammanfattning : Biology has entered a challenging, information-intense period where computational experiments are complementing traditional experiments. A plethora of new techniques have allowed biological processes to be investigated on a global scale. LÄS MER

  4. 23. Streptococcal cell surface proteins : structure and gene characterisation

    Författare :Viatcheslav Katerov; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; virologi; mykologi; Microbiology; bakteriologi;

    Sammanfattning : Streptococcus pyogenes (group A streptococci, GAS) is a potent human pathogen known to express a number of cell surface associated virulence factors. It is an established fact that these different surface proteins play an important role during infection. LÄS MER

  5. 24. RNA-mediated gene regulation in Neisseria meningitidis and other nasopharyngeal pathogens

    Författare :Hannes Eichner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neisseria meningitidis is a transient commensal bacterium of the upper respiratory tract and spreads through respiratory secretions produced by the carrier. While mostly harmless, the bacterium can cause invasive meningococcal disease by entering the circulatory system, leading to septicaemia and/or meningitis. LÄS MER

  7. 25. On the mechanisms and consequences of cell to cell DNA transfer

    Författare :Jacob Ehnfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Development of cancer is a multistep process where an accumulation of genetic alterations drives normal cells to malignancy. In most cancer cells genetic changes can be observed both at the level of point mutations and as gains and losses of chromosomes. LÄS MER
