  1. 6. Analysis of chromosomal rearrangements and gene copy number changes in breast cancer cells

    Författare :Pär Lundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Genome changes in terms of numerical chromosomal aberrations and structural rearrangements, including deletions, amplifications and translocations, gradually accumulate in the genome during tumor development. These genomic changes are likely to play an important role in the process of tumor progression. LÄS MER

    Sammanfattning : The brown macroalgae Fucus radicans is endemic to the Baltic Sea, but little is known about this newly described species. This thesis investigates the ecology and role of F. radicans within the species poor Baltic Sea ecosystem. The thallus of F. LÄS MER

  4. 8. Studies of congenital genetic aberrations behind childhood leukemia

    Författare :Benedicte Bang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Acute lymphoblastic leukemia (ALL) is the most common cancer in childhood, and most frequently (85%) of B-cell precursor type (BCP-ALL). Acquired chromosomal rearrangements or aneuploidies are the recurrent, often prenatal, initiators of BCP-ALL. LÄS MER

  5. 9. Genetic content of clinical pneumococcal isolates and its relation to disease outcome

    Författare :Jessica Dagerhamn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Streptococcus pneumoniae is a Gram-positive bacterium that can cause a wide range of diseases. These include otitis media, sinusitis, pneumonia and meningitis. It can, however, also cause asymptomatic carriage thereby behaving almost like a commensal. LÄS MER
