  1. 6. 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

  3. 7. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe

    Författare :Johanna J Sjölander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Caffeine; Cell cycle; Checkpoint; Cdc25; Wee1; TORC1; FHIT; Proliferation; Aph1; Redox; Hypoxia; H2O2; Cysteine; Thiol; Allosteric; MAPK; Sty1; MAPKK; Wis1;

    Sammanfattning : This thesis covers intracellular stress signaling through genotoxic stress, overriding of checkpoint control, as well as cellular redox status in hypoxic and oxidative stress Papers I and II: Caffeine has been shown to override cell cycle checkpoints in humans as well as in the fission yeast Schizosaccharomyces pombe. Understanding of the mechanism may aid in the development of compounds with similar overriding mechanisms for sensitization in cancer therapy. LÄS MER

  4. 8. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Författare :Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. LÄS MER

  5. 9. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA

    Författare :Susanne Wisén; Bengt Mannervik; Enrique Flores; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; NtcA; transcription regulation; cyanobacteria; redox regulation; DNA binding; nitrogen fixation; Anabaena PCC 7120; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. LÄS MER

  7. 10. Redox regulation of T cells in autoimmunity

    Författare :Jaime Rose James; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Autoimmune disorders affect a significant part of the population and therefore present a serious health and economic burden. One of the most common autoimmune diseases is rheumatoid arthritis (RA), affecting 0.5-1% of the population which is mediated by both genetic and environmental risk factors. LÄS MER
