  1. 26. Role of Wnt-5a in breast cancer

    Författare :Janna Sand-Dejmek; Malmö Experimentell patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General pathology; signal transduction; metastasis; adhesion; breast cancer; Syk; Wnt-5a; DDR1; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Sammanfattning : Breast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. LÄS MER

  2. 27. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5

    Författare :António Martins; Per O. Ljungdahl; Bruno André; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; regulated proteolysis; endoprotease; serine protease; substrate specificity; subcellular fractionation; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. LÄS MER

  3. 28. Cellular Resilience and Fragility in Response to Environmental and Gene Expression Perturbations

    Författare :Lars-Göran Ottosson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; Phenomics; Liquid microcultivation; Tellurite; Gene overexpression; gToW; Cellular signalling; HOG; Protein phosphatase;

    Sammanfattning : Cells are constantly subjected to perturbations. Whether these are extracellular or intracellular, they can be detrimental to cellular fitness. The cell has evolved elaborate systems and mechanisms that allow it to remain functional in the face of disturbances. LÄS MER

  4. 29. Alzheimer's disease mutations and cellular signalling

    Författare :Monika Vestling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease is the most frequent cause of dementia in elderly and is characterised neuropathologically by the extracellular deposition of amyloid plaques (containing the 39-43 amino acid Abeta peptide), as well as intracellular neurofibrillary tangles (NFTs) composed primarily of an abnormally hyperphosphorylated form of the microtubule-associated protein tau. A proportion (10- 15%) of Alzheimer's disease cases is familial, the remainder being sporadic. LÄS MER

  5. 30. Signal transduction via ion fluxes : a cell imaging study with emphasis on calcium oscillations

    Författare :Per Uhlén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Calcium; Ca2 signalling; Ca2 oscillation; InsP3; InsP3 receptor; Na; K-ATPase; ouabain; physical interaction; FRET; spectral analysis; confocal microscopy;

    Sammanfattning : Signal transduction via ion fluxes is of vital importance for all mammalian cells. Cells can exploit ion regulatory mechanisms to generate and transmit intracellular signals. Improvements in digital microscopic imaging technology have made it possible to explore micro-environments and complex intracellular machineries. LÄS MER
