  1. 1. TRAF6 stimulates TGFβ-induced oncogenic signal transduction in cancer cells

    Författare :Shyam Kumar Gudey; Marene Landström; Urban Lendahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c-Jun; invasion; non-Smad; Notch; NICD; oncogenesis; presenilin1; PKCζ; prostate cancer; p21; p38; p300; Snail1; TGFβ; TβRI; TACE; TRAF6; ubiquitination; TGFbeta signal transduction; Pathology; patologi;

    Sammanfattning : Prostate cancer is one of the leading causes of cancer-related deaths in men worldwide, with 10,000 new cases/year diagnosed in Sweden. In this context, there is an urgent need to identify new biomarkers to detect prostate cancer at an initial stage for earlier treatment intervention. LÄS MER

  3. 2. ß2 integrin-induced signal transduction events in human neutrophils

    Författare :Fredrik Melander; Malmö Experimentell patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; integrins; signal transduction; Rho GTPases; kinases; c-Cbl; General pathology; patologisk anatomi; pathological anatomy; Patologi allmän ; neutrophils;

    Sammanfattning : Inflammation is a localized protective response in vascularized tissues and can be induced by microbial infection or cell and tissue injury. Polymorphonuclear neutrophils (PMN) are the most common white blood cells and are recognized as major cellular mediators of acute inflammation. LÄS MER

  4. 3. The Tyrosine Kinase GTK : Signal Transduction and Biological Function

    Författare :Cecilia Annerén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinases; GTK; SHB; proliferation; survival; differentiation; β cells; pancreatectomy; cytokines; diabetes; PC12 cells; NGF; streptozotocin; focal adhesion kinase; RAP1; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

  5. 4. Fibroblast growth factor-induced signal transduction

    Författare :Peter Klint; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Fibroblast growth factors (FGFs) evoke cellular responses by binding to FGF receptors (FGFRs). FGFRs are cell surface expressed membrane-spanning receptors with intrinsic stimulatable tyrosine kinase activity. This thesis describes the cell proliferation or differentiation. LÄS MER

  7. 5. Robustness analysis of eukaryotic signal transduction with emphasis on the HOG pathway in Saccharomyces cerevisiae

    Författare :Lars-Göran Ottosson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; systems biology; robustness; gTOW; signal transduction; MAPK signalling; HOG; kinase; phosphatase; transcription factor;

    Sammanfattning : Fundamental to life, in particular for unicellular microorganisms that generally are subjected to rapidly changing environmental parameters, is the need to monitor and integrate environmental stimuli with the internal cell status. The sensing of stimuli are typically initiated at the plasma membrane and then transmitted by means of intracellular signalling networks to elicit proper cellular responses. LÄS MER
