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

    Author : Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Signal Transduction in Malignant Cells – Transformation, Activation and Differentiation

    Author : Karin Kårehed; Fredrik Öberg; Jan-Ingvar Jönsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; transformation; PDGF; PI3K; Rho-GTPase; U-937; FcγRI; macrophage; Stat1; PKR; NFκB; ATRA; differentiation; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Pathology; Patologi;

    Abstract : All aspects of cell life are regulated by signal transduction mechanisms. This thesis describes the regulatory roles of a few key signal transduction molecules involved in three major biological responses. READ MORE

  5. 3. Regulation of GRAF1 membrane sculpting function during cell movement

    Author : Monika K. Francis; Richard Lundmark; Pekka Lappalainen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocytosis; migration; polarisation; tension; CLIC GEEC; GRAF1; Rho GTPase; Cdc42; Rab8; medicinsk biokemi; Medical Biochemistry;

    Abstract : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. From Cell Shape to Body Shape: Epithelial Morphogenesis in Drosophila melanogaster

    Author : Shai Mulinari; Sociologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Odd-skipped; morphogenesis; Hedgehog; segment boundaries; segmental grooves; Actin; Drosophila; DRhoGEF2; Myosin; Diaphanous; Rho GTPase; cytoskeleton; Rho1;

    Abstract : Embryonic development is associated with extensive rearrangements of tissues. The driving force for these rearrangements is generated by a dynamic reorganization of the Actin cytoskeleton of individual cells. READ MORE
