  1. 1. Vesicle proteins as markers for neuroendocrine tumors

    Författare :Anne-Marie Levin Jakobsen; Göteborgs universitet; []
    Nyckelord :Neuroendocrine tumours; gastrointestinal tract; pancreas; adrenal; vesicle proteins; ; SV2; NESP55; VMAT1; VMAT2; MIBG;

    Sammanfattning : The neuroendocrine (NE) tumours comprise a diversity of tumours which share commonproperties, e.g. the capacity to produce, store and release hormones. A prominent feature ofthe NE phenotype is the production of secretory granules with associated vescicle proteins,e. LÄS MER

  2. 2. Vesicle transport in chloroplasts with emphasis on Rab proteins

    Författare :Mohamed Alezzawi; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chloroplast; vesicle; transport; Arabidopsis; Rab; lipid; clathrin; protein; COPI; COPII;

    Sammanfattning : Chloroplasts perform photosynthesis using PSI and PSII during its light-dependent phase. Inside the chloroplast there is a membrane called thylakoid. The thylakoid membranes are an internal system of interconnected membranes that carry out the light reactions of photosynthesis. LÄS MER

  3. 3. Membrane-bound proteins : Characterization, evolution, and functional analysis

    Författare :Misty M. Attwood; Helgi B. Schiöth; Arne Elofsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transmembrane protein; alpha-helical membrane protein; evolution membrane proteins; 3TM; 4TM; 5TM; trispanin; Bioinformatics; Bioinformatik;

    Sammanfattning : Alpha-helical transmembrane proteins are important components of many essential cell processes including signal transduction, transport of molecules across membranes, protein and membrane trafficking, and structural and adhesion activities, amongst others. Their involvement in critical networks makes them the focus of interest in investigating disease pathways, as candidate drug targets, and in evolutionary analyses to identify homologous protein families and possible functional activities.

  4. 4. The contribution of proteins and lipids to COPI vesicle formation and consumption

    Författare :Fredrik Kartberg; Göteborgs universitet; []
    Nyckelord :ARF1; COPI; ARFGAP; vesicle; fusion; diffusion;

    Sammanfattning : In the secretory pathway, movement of proteins between compartments occurs through small (50-100 nm) vesicles. The coat of COPI vesicles is composed the small GTPase ARF1 and the large coatomer complex. In the secretory pathway, these vesicles mediate Golgi-to-ER and intra-Golgi transport. LÄS MER

  5. 5. Transport Modes in Nanotube-Vesicle Networks

    Författare :Michal Tokarz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; confinement; liposome; biomimetic; micromanipulation; Vesicle; electrophoresis; network; nanotube; transport;

    Sammanfattning : Methods for construction of surface-immobilized microscopic networks of phospholipid bilayer vesicles (3-50 µm in diameter) interconnected by lipid tubes (30-150 nm in radius), have previously been developed. The networks have controlled connectivity and are well-defined with regard to container size, content, angle between nanotube extensions, and nanotube length. LÄS MER
