  1. 1. Signalling in plant mitochondria. Redox regulation of gene expression & characterisation of a pea nucleoside diphosphate kinase

    Författare :Martha L Escobar Galvis; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondrial gene expression; redox; respiratory complex II; NDPK; protein interactions; heat-stress; Växtbiokemi; Plant biochemistry;

    Sammanfattning : This work contributes to our understanding of mitochondrial responses to changing environmental conditions in plants. The first part of this thesis is focused in the study of redox regulation of mitochondrial gene expression. By using inhibitors, the redox state of the components of the mitochondrial respiratory chain was selectively affected. LÄS MER

  3. 2. Regulation of chloroplast gene expression in higher plants

    Författare :Anna Furo Tullberg; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein tyrosine kinase; plastoquinone pool; redox; Pisum sativum; Sinapis alba; petB; psaB; chloroplast; gene expression; Physiological biophysics; Växtfysiologi; light harvesting complex II;

    Sammanfattning : Chloroplast gene expression is regulated by developmental and environmental signals. It has been proposed that there is a direct coupling between electron transport in biological membranes and gene expression (J. F. Allen, 1992, Biochim. LÄS MER

  4. 3. Molecular Pharmacology and Structure Function Modelling of the Leukotriene B4 Receptor BLT1

    Författare :Alan Sabirsh; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; fluidity; redox; chemotaxis; luciferase; calcium; ligand binding; point mutation; modelling; antibody; BLT1; leukotriene; pharmacology; GPCR; G-protein; receptor;

    Sammanfattning : Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LÄS MER

  5. 4. Mechanisms and genes controlling the signalling network for biotic and abiotic stress defences in Arabidopsis thaliana (L.) Heyhn : Functional cross-talk between photo-produced reactive oxygen species, photosynthesis and plant disease defence responses

    Författare :Christine Chi-Chen Chang; Stanislaw Karpinski; Christine Foyer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactive oxygen species; Arabidopsis thaliana; signalling work; biotic stress; abiotic stress; Plant physiology; Växtfysiologi;

    Sammanfattning : Excess excitation energy, mechanical injury and defence against pathogens, each trigger rapid production of reactive oxygen species (ROS) in Arabidopsis thaliana leaves. ROS, such as hydrogen peroxide (H2O2), are required for the induction of systemic acquired acclimation and may lead to redox changes in photosynthetic electron transport (PET). LÄS MER

  7. 5. Organic bioelectronic devices to control cell signalling

    Författare :Karin Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nervous system consists of a network of specialized cells that coordinate the actions of the body by transmitting information to and from the brain. The communication between the nerve cells is dependent on the interplay of both electrical and chemical signals. LÄS MER
