  1. 16. Understanding molecular mechanisms of protein tyrosine kinases by molecular dynamics and free energy calculations

    Författare :Yaozong Li; Kwangho Nam; Magnus Wolf-Watz; Amedeo Caflisch; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinase; IRK; IGF-1RK; phosphorylation; activation loop; molecular dynamics; phosphoryl transfer; alchemical free energy; dynamical network; correlation map; PCA; motion projection; Gaussian softcore; free energy landscape; kinase catalysis;

    Sammanfattning : Background: Insulin receptor kinase (IRK) and Insulin-like growth factor 1 receptor kinase (IGF-1RK) are two important members in the large class of tyrosine kinase receptors. They play pivotalroles in the regulation of glucose homeostasis, cell proliferation, differentiation, motility, andtransformation. LÄS MER

  3. 17. Molecular targets for glucocorticoids in macrophages: cytosolic phospholipase A2 and cytokine formation

    Författare :Karin Gewert; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; signal transduction; dexamethasone; cytosolic phospholipase A2; glucocorticoids; macrophages; protein kinase C; mitogen-activated protein kinases; TNF-alpha; IL-1beta; protein phosphatases; okadaic acid; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : The aim of this investigation has been to study mechanisms by which glucocorticoids inhibit inflammatory processes in vitro. Type IV cytosolic 85 kDa phospholipase A2 (cPLA2) is an important modulator of inflammatory responses that is present in macrophages as well as in other cell types. LÄS MER

  4. 18. Protein kinase C-dependent regulation of the epithelial barrier

    Författare :Anita Sjö; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The intestinal epithelium is essential for the absorption of nutrients and for the defence against harmful substances in the gut. The permeability and barrier functions of epithelia are mainly controlled by the intercellular tight junctions. LÄS MER

  5. 19. Studies on the Differential Specificity of Protein Kinases and Its Applications

    Författare :Mart Loog; Bengt Jergil; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Protein kinases; protein kinase inhibitors; substrate specificity; peptide libraries; affinity chromatography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Protein kinases are enzymes that catalyse the phosphoryl transfer from the g-phosphate of ATP to acceptor amino acids in proteins. The specificity of selected model protein kinases was studied at three different levels using a) novel bi-substrate-analogue inhibitors, b) synthetic peptide substrates and c) mutated protein substrate analogues.

  7. 20. Receptor tyrosine kinase c-Kit signalling in hematopoietic progenitor cells

    Författare :Charlotte Edling; Bengt Hallberg; Pontus Aspenström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RTK; c-Kit; MAPK; PI3K; PKC; hematopoietic cells; proliferation; differentiation; apoptosis; Pathology; Patologi;

    Sammanfattning : The receptor tyrosine kinase (RTK) c-Kit is expressed in hematopoietic stem and progenitor cells, mast cells and in several non-hematopoietic tissues. In the hematopoietic system c-Kit and its ligand Steel Factor (SF, aka Stem Cell Factor) are critical for proliferation, survival and differentiation. LÄS MER
