  1. 1. Regulation of NF-κB by Calmodulin

    Author : Åsa Antonsson; Thomas Grundström; Ylva Engström; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; NF-κB; calmodulin; transcription; calcium; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Cells experience numerous external signals which they must respond to. Such signals arriving at the cell surface are transduced via various signal transduction pathways and often ultimately result in regulation of transcription. READ MORE

  2. 2. Aspects of interferon alpha signalling in hematopoetic cells

    Author : Lennart Carlsson; erik lundgren; Ulrich Kalinke; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; interferon; human; B-lymphocyte; survival; proliferation; myeloma; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The type I interferons (IFN) are a family of cytokines with pleiothropic activities that include inhibition of viral replication, cell proliferation and activation of the immune system. These properties give the IFNs important physiological and pathological roles in infection and cancer and have led to their therapeutic use for many clinical conditions. READ MORE

  3. 3. Zonal organization of the mouse olfactory systems

    Author : Fredrik Gussing; Staffan Bohm; Anna Berghard; Diego Restrepo; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; olfactory; vomeronasal; gene expression; zone; organization; behavior; Molekylärbiologi; Molecular biology; 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

  4. 4. RNA-mediated virulence gene regulation in the human pathogen Listeria monocytogenes

    Author : Edmund Loh; Jörgen Johansson; Nancy Freitag; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; virulence; ncRNAs; PrfA; 5´-UTRs; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The Gram-positive human pathogen Listeria monocytogenes uses a wide range of virulence factors for its pathogenesis. The majority of its virulence genes are encoded on a 9-kb pathogenicity island and are controlled by the transcriptional activator PrfA. READ MORE

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

    Author : Juha Saarikettu; Thomas Grundström; Dan Holmberg; Mikael Sigvardsson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; Molecular biology; 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
