  1. 1. Plasma membrane/cytoskeleton interactions in plants

    Detta är en avhandling från Section of Plant Physiology, P.O.Box 117, S-221 00 Lund, Sweden

    Författare :Anders Sonesson; Lund University.; Lunds universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Triton X-114; hydrophobic tubulin; tubulin; actin; cytoskeleton; Brij 58; inside-out; plasma membrane; plant; cauliflower; Physiological biophysics; Växtfysiologi;

    Sammanfattning : The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. LÄS MER

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

    Detta är en avhandling från Department of Experimental Medical Science, Lund Univeristy

    Författare :Shai Mulinari; Lund University.; Lunds universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Odd-skipped; morphogenesis; Hedgehog; segment boundaries; segmental grooves; Actin; Drosophila; DRhoGEF2; Myosin; Diaphanous; Rho GTPase; cytoskeleton; Rho1;

    Sammanfattning : 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. LÄS MER

  3. 3. Structural Study of the WH2 Family and Filamin: Implications for Actin Cytoskeleton Regulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Adeleke H. Aguda; Uppsala universitet.; [2006]
    Nyckelord :Biochemistry; Actin; Thymosin; Ciboulot; N-WASP; Filamin; Calponin homology domain; WH2; Protein Crystallography; Biokemi;

    Sammanfattning : Cellular processes like motility, chemotaxis, phagocytosis and morphogenesis are dependent on the dynamic regulation of the actin cytoskeleton. This cytoskeleton system is tightly controlled by a number of diverse actin-binding proteins (ABPs) by various mechanisms described as nucleation, polymerization, capping, severing, depolymerization and sequestration.

  4. 4. Mechanism of F-actin crosslinking by filamin A and the anti-inflammatory functions of plasma gelsolin in bodily fluids

    Detta är en avhandling från Göteborg : Göteborg University

    Författare :Teresia Magnuson Osborn; Göteborgs universitet.; Gothenburg University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytoskeleton; Crosslinking; F-actin; Filamin; Gelsolin; Inflammation; Plasma; Platelet-activating factor; Lysophosphatidic acid; Rheumatoid arthritis;

    Sammanfattning : Gelsolin (GSN) and filamin A (FLNa) are two actin-binding proteins discovered in our laboratory over 30 years ago. GSN is a calcium-activated actin severing and barbed end capping protein that is expressed as both intracellular and extracellular (plasma gelsolin, pGSN) isoforms. LÄS MER

  5. 5. The role of PKC in neuronal differentiation and in regulation of the actin cytoskeleton during neurite outgrowth

    Detta är en avhandling från Ulrika Trollér, Entr. 78, 3rd floor, U-MAS, S-205 02 Malmö, Sweden

    Författare :Ulrika Trollér; Lund University.; Lunds universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytogenetics; Genetik; cytogenetik; Rho-family; actin cytoskeleton; neurite; differentiation; PKC; regulatory domain; Genetics;

    Sammanfattning : Protein kinase C (PKC) is a family of serine/threonine kinases subgrouped into classical (α, βI, βII, γ), novel (δ, ε, η, θ) and atypical (ζ, ι/λ) isoforms. PKC can be activated by phorbol esters, and prolonged treatment of neuroblastoma cells has been shown to induce neuronal differentiation with neurite outgrowth and increased expression of neuronal genes.
