  1. 21. Prognostic markers in pediatric leukemia and mechanisms of KRAS induced leukemogenesis

    Författare :Anna Staffas; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prognostic markers; AML; T-ALL; leukemia; FLT3; NPM1; ERG; BAALC; KRAS;

    Sammanfattning : Leukemia results from uncontrolled growth of genetically altered blood cells. Depending on the cell type of origin, the leukemia is defined as T-cell, B-cell, or myeloid and as acute or chronic depending on its characteristics. However, patients with a certain subtype of leukemia (e.g. LÄS MER

  3. 22. The role of the tumor suppressor gene, FBW7, and mechanisms of its inactivation in cancer

    Författare :Shahab Akhoondi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The F-box protein FBW7 is a tumor suppressor and SCF ubiquitin ligase targeting several key oncoproteins for proteasomal degradation. In this thesis we addressed whether the FBW7 gene is inactivated by mutations in various human tumor types and explored alternative mechanism(s) for the inactivation of FBW7. LÄS MER

  4. 23. Invasion and Proliferation in Malignant Cells

    Författare :Sofie Svensson Månsson; Malmö Patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; oncology; Cytology; breast cancer; squamous cell carcinoma; basal cell carcinoma; p16; proliferation; invasion; Cytologi; onkologi; cancer;

    Sammanfattning : Two key events in the oncogenic process of tumor cells are to acquire uncontrolled proliferation and invasive properties. This allows the tumor to grow and invade beyond the tissue from which the tumor cells originate. LÄS MER

  5. 24. Functional genomics of vascular endothelial cells

    Författare :Elisabet Wallgard; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vasculature; endothelial cells; angiogenesis; vascular endothelial growth factor VEGF ; Notch; transcriptome; genomics; microarray; tumor; retina; morpholino knockdown;

    Sammanfattning : Angiogenesis, the formation of new blood vessels from preexisting ones, is a process involved in normal development as well as in several pathological conditions, such as cancer, ischemic heart disease, wound healing and certain retinal complications. Antiangiogenic targeting is therefore a promising new therapeutic principle. LÄS MER

  7. 25. Studies on gamma-secretase activity and products

    Författare :Jenny Frånberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : gamma-Secretase is a transmembrane aspartyl protease involved in processing of a multitude of functionally diverse substrates within their transmembrane domains. gamma-Secretase cleavage of the amyloid precursor protein (APP) generates the APP intracellular domain (AICD) and the amyloid beta-peptide (Abeta).
