  1. 1. Establishing the mechanistic basis of sugar transport

    Författare :Abdul Aziz Qureshi; David Drew; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane transport; transport energetics; nucleotide-sugar transporters; glucose transporters; malaria; cancer; Biochemistry; biokemi;

    Sammanfattning : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. LÄS MER

  3. 2. Studies of the Carbon and Energy Metabolism in the Moss Physcomitrella patens

    Författare :Anders Nilsson; Hans Ronne; Leszek Kleczkowski; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hexokinase; SnRK1; sugar signaling; carbon metabolism; Physcomitrella patens; shuttle vector; subcellular localization; model organism; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Since a proper balance between anabolic and catabolic reactions is essential for all eukaryotes, the basic mechanisms for regulation of the energy and carbon metabolism have been conserved throughout evolution. The moss Physcomitrella patens, which belongs to one of the basal clades among land plants, has many unique properties that make it an excellent plant model system. LÄS MER

  4. 3. Regulation of insulin producing cells, stress responses and metabolism in Drosophila

    Författare :Neval Kapan; Dick R. Nässel; Alberto Ferrus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insulin signaling; Drosophila melanogaster; peptide hormones; neuropeptides; GABA; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : In Drosophila, neuropeptides have regulatory roles in development, growth, metabolism and reproduction. This study focused on GABA and the neuropeptides Drosophila tachykinin (DTK), short neuropeptide F (sNPF), adipokinetic hormone (AKH), corazonin (CRZ) and Drosophila insulin-like peptides (DILPs) as possible regulators of metabolic stress responses and homeostasis.

  5. 4. Biochemical and Physiological Characterization of Nonsymbiotic Plant Hemoglobins

    Författare :Nélida Leiva; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; Non-symbiotic hemoglobin; Sugar beet; Ligand binding; Nitric oxide; Gene expression; Gene overexpression; Poplar; Arabidopsis; Lepidium campestre.;

    Sammanfattning : Hemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. LÄS MER

  7. 5. Computational analysis of oligosaccharide conformations – methodological development, applied studies, and design of glycomimetics

    Författare :Francesco Strino; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; histo-blood group antigens; Burkholderia cepacia; genetic algorithms; norovirus; selenoglycosides; sugar conformations; thioglycosides; saccharide conformations;

    Sammanfattning : Carbohydrates are the most abundant class of biomolecules. Besides their roles as structural elements and energy storage, they are involved in signaling and recognition processes. Their functions and activities depend on their preferred conformations. LÄS MER
