  1. 1. From protein production to genome evolution in Escherichia coli

    Författare :Susan Schlegel; Jan-Willem de Gier; Peter Neubauer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; BL21 DE3 ; protein production; membrane proteins; secretory proteins; genome evolution; Biochemistry; biokemi;

    Sammanfattning : The aim of my Ph.D. studies was to improve production yields of membrane- and secretory proteins in the widely used E. coli protein production strain BL21(DE3). LÄS MER

  3. 2. Hybridization and Evolution in the Genus Pinus

    Författare :Baosheng Wang; Xiao-Ru Wang; Sally Aitken; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adaptation; biogeography; coalescent simulation; cytoplasmic genome; demographic history; genetic diversity; hybridization; migration; Pinus; population structure; selection; speciation; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

  4. 3. Genome-wide Characterization of RNA Expression and Processing

    Författare :Ammar Zaghlool; Lars Feuk; Rickard Sandberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA sequencing; RNA splicing; RNA processing; Gene expression; Molekylär genetik; Molecular Genetics;

    Sammanfattning : The production of fully mature protein-coding transcripts is an intricate process that involves numerous regulation steps. The complexity of these steps provides the means for multilayered control of gene expression. LÄS MER

  5. 4. Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies

    Författare :Yasir Ruhayel; Malmö Molekylärgenetisk reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytoplasmic and nuclear; Receptors; Prostatic neoplasms; genetic; Polymorphism; male; Infertility; Hypogonadism; Genetic association studies; Case–control studies; Androgens;

    Sammanfattning : Androgen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively.

  7. 5. Mitochondria and Human Evolution

    Författare :Max Ingman; Ulf Gyllensten; Peter Underhill; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mitochondria; hominidae; human evolution; population genetics; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : Mitochondrial DNA (mtDNA) has been a potent tool in studies of the evolution of modern humans, human migrations and the dynamics of human populations over time. The popularity of this cytoplasmic genome has largely been due to its clonal inheritance (in Man) allowing the tracing of a direct genetic line. LÄS MER
