  1. 1. Type III secretion- the various functions of the translocon operon in bacterial pathogenesis

    University dissertation from Umeå : Molekylärbiologi

    Author : Jeanette E Bröms; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Yersinia; Pseudomonas aeruginosa; type III secretion; chaperone; translocation; regulation; lcrGVHyopBD; pcrGVHpopBD; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : In order to establish colonisation of a human host, pathogenic Yersinia use a type III protein secretion system to directly intoxicate host immune cells. Activation of this system requires target cell contact and is a highly regulated process. READ MORE

  2. 2. Zonal organization of the mouse olfactory systems

    University dissertation from Umeå : Molekylärbiologi

    Author : Fredrik Gussing; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; olfactory; vomeronasal; gene expression; zone; organization; behavior; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Animals survey their environment for relevant odorous chemical compounds by means of the olfactory system. This system is in most vertebrates divided into a main and accessory olfactory system with two specialized neuroepithelia, the olfactory and the vomeronasal epithelium, respectively. READ MORE

  3. 3. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

    University dissertation from Umeå : Molekylärbiologi

    Author : Juha Saarikettu; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. READ MORE

  4. 4. Frameshifting as a tool in analysis of transfer RNA modification and translation

    University dissertation from Umeå : Molekylärbiologi

    Author : Ramune Leipuviene; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; minor tRNA; frameshifting; suppression; L9; hopping; tRNA thiolation; [Fe-S] cluster; [Fe-S] protein; TtcA; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Studies of ribosomal reading frame maintenance are often based on frameshift mutation suppression experiments. In this thesis, suppression of a frameshift mutation in Salmonella enterica serovar Typhimurium by a tRNA and a ribosomal protein are described. READ MORE

  5. 5. Antiphagocytosis by Yersinia pseudotuberculosis role of the YopH target proteins

    University dissertation from Umeå : Molekylärbiologi

    Author : Ming Yuan; Umeå universitet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Cas; Fyb; mAbp1; SKAP-HOM; Yersinia pseudotuberculosis; YopH; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The enteropathogenic bacterium Yersinia pseudotuberculosis binds to β1 integrins on a host cell via its surface protein invasin. This event stimulates signal transduction to the actin cytoskeleton of the eukaryotic cell, which allows the cell to engulf the bacterium that is attached to its surface. However, the pathogen Y.
