  1. 1. Cell signaling by Rho and Miro GTPases : Studies of Rho GTPases in Cytoskeletal Reorganizations and of Miro GTPases in Mitochondrial Dynamics

    Författare :Åsa Fransson; Pontus Aspenström; Harry Mellor; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ras superfamily; Rho GTPases; cytoskeleton; Miro GTPases; mitochondrial dynamics; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The Ras superfamily of GTPases embraces six major branches of proteins: the Ras, Rab, Ran, Arf, Rho and Miro subfamilies. The majority of GTPases function as binary switches that cycle between active GTP-bound and inactive GDP-bound states. This thesis will focus primarily on the biological functions of the Rho and Miro proteins. LÄS MER

  3. 2. Rho-GTPases in Rheumatoid Arthritis

    Författare :Eric Malmhäll-Bah; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rho-GTPases; rheumatoid arthritis; innate immunity; adaptive immunity; RA treatment;

    Sammanfattning : The success of alleviating rheumatoid arthritis (RA) symptoms is complicated by both heterogeneity of the disease and lack of predictive markers to guide treatment options. Deregulated Rho-GTPases, a family of hydrolase enzymes catalyzing guanosine triphospate (GTP) to guanosine diphospate (GDP), have a detrimental role in many diseases including RA. LÄS MER

  4. 3. Rho-GTPases in Morphogenesis and Differentiation of the Developing Pancreas

    Författare :Thomas Greiner; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; diabetes; beta cell; cell adhesion; migration; delamination; morphogenesis; tubulogenesis; pancreas; Cdc42; Rho-GTPase; Rac1;

    Sammanfattning : Branched tubular networks constitute the basic structure of many organs to increase surface area and to transport fluids and gases. Glandular organs such as the pancreas arise from multilayered epithelium, which undergoes de novo lumen formation and extensive remodeling and branching. LÄS MER

  5. 4. RICH-1, a Multifunctional RhoGAP Domain-containing Protein, Involved in Regulation of the Actin Filament System and Membrane-trafficking

    Författare :Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Rho GTPase; RhoGAP; actin; BAR domain; membrane-trafficking; formin homology proteins; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. LÄS MER

  7. 5. Cytoskeletal Regulation During Embryonic Development in Drosophila melanogaster

    Författare :Mojgan Padash; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural science; DRhoGEF2; Actin cytoskeleton; Rho GTPase;

    Sammanfattning : The development of multicellular organisms is associated with extensive rearrangements of cells and tissues. The driving force for these rearrangements is generated by the cell's actin cytoskeleton. During many morphogenetic processes dynamic rearrangement of the actin cytoskeleton is regulated by small GTPases of the Rho-family. LÄS MER
