  1. 16. Heparan Sulfate Regulation of Fibroblast Growth Factor (FGF) Receptor-1 Signal Transduction

    Författare :Lars Lundin; Lena Claesson-Welsh; Marco Presta; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; FGF; FGFR; dimerisation; signal transduction; heparan sulfate; proteoglycan; heparin; VEGF; embryonal stem cell; endothelial cell; differentiation; Patologi; Pathology; Patologi;

    Sammanfattning : Fibroblast growth factors (FGFs) constitute a family (currently FGF-1 to FGF-23) of polypeptides that are essential in embryonal development and adult physiology, in animals from nematodes to humans. FGFs bind to four receptor tyrosine kinases, denoted FGFR-1 to FGFR-4. LÄS MER

  3. 17. Signalling pathways in renal cell carcinoma with a focus on telomerase regulation

    Författare :Raviprakash Tumkur Sitaram; Göran Roos; Anders Bjartell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renal cell carcinoma; DJ-1; NBS1; PTEN; WT1; cMyc; hTERT; telomerase; Pathology; Patologi; patologi; Pathology;

    Sammanfattning : Telomerase is a ribonucleoprotein complex that catalyses telomeric repeat addition at the ends of chromosomes. The catalytic subunit, hTERT, acts as a key determinant for telomerase activity control; the induction of hTERT expression is required for telomerase activity. LÄS MER

  4. 18. Molecular Analysis of Normal Human Skin and Basal Cell Carcinoma Using Microdissection Based Methods

    Författare :Anna Asplund; Fredrik Pontén; Uffe Birk Jenssen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; skin; basal cell carcinoma; microdissection; X-chromosome inactivation; Patologi; Pathology; Patologi;

    Sammanfattning : The aim of this thesis was to gain further insight into the biology of normal human skin and basal cell carcinoma (BCC). Morphology in combination with microdissection was used as primary tool for sampling. LÄS MER

  5. 19. The Role of Chemokines in Mast Cell Migration

    Författare :Mikael Juremalm; Timothy J. Williams; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Mast cells; chemotaxis; calcium flux; chemokines and chemokine receptors; Patologi; Pathology; Patologi; Pathology; patologi;

    Sammanfattning : Mast cells are very potent multifunctional effector cells of the immune system normally distributed throughout connective tissues. An accumulation of mast cells has been described in several pathological conditions such as allergic- and autoimmune inflammations and in certain tumours. LÄS MER

  7. 20. Biology of a small RNA virus that infects Drosophila melanogaster

    Författare :Sajna Anand Sadanandan; Dan Hultmark; Francis Jiggins; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nora virus; Drosophila melanogaster; virus biology; host-pathogen interaction; molekylärbiologi; Molecular Biology;

    Sammanfattning : Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. LÄS MER
