  1. 21. Structure-Function Relationships of Pi Class Glutathione Transferase Studied by Protein Engineering

    Författare :Usama M. Hegazy; Bengt Mannervik; Mikael Widersten; T. J. Mantle; Uppsala universitet; []
    Nyckelord :Biochemistry; Glutathione transferase; targeted chemical modification; lock-and-key motif; cooperativity; stucture-function relationship; protein engineering; unnatural amino acid; site-specific mutation; Biokemi;

    Sammanfattning : The glutathione transferases (GSTs) represent a superfamily of dimeric proteins involved in cellular detoxication by catalyzing the nucleophilic addition of the reduced glutathione (GSH) to the hydrophobic electrophiles. The present work focuses on the functional role of the conserved structures of GSTP1-1. LÄS MER

  2. 22. Vascular endothelial growth factor receptors in angiogenesis

    Författare :Kui Huang; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; endothelial cells; VEGF receptor; signal transduction; pertide; angiogenesis; Genetik; Clinical genetics; Klinisk genetik; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Angiogenesis is a process in which new capillaries sprout from preexisting blood vessels. Vascular endothelial growth factor (VEGF) promotes endothelial cell proliferation and migration and thereby stimulates angiogenesis. VEGF receptors (VEGFRs) have been implicated as key regulatory components in endothelial cells. LÄS MER

  3. 23. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands

    Författare :Stefan Jonsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; X-ray crystallography; Phenanthroline; Supramolecular Catalysis; Jacobsen-Katsuki Epoxidation; Mn salen ; Hydrogen-bonding; Supramolecular Chemistry; 2-Pyridone; Organisk kemi;

    Sammanfattning : This thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. LÄS MER

  4. 24. Early events in T cell development

    Författare :Karin Leandersson; Malmö Cancerimmunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; pTalpha; gammadelta T cell; alphabeta T cell; development; thymus; thymocyte; serology; transplantation; Immunologi; serologi;

    Sammanfattning : T cells constitute a heterogenous population of lymphocytes. Their unifying property is that they express surface bound antigen-receptors, called T cell receptors (TCRs). The TCR is a heterodimer composed of either TCRalpha and beta chain proteins (alphabeta TCR) or gamma and delta chain proteins (gammadelta TCR). LÄS MER

  5. 25. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective

    Författare :Robin Öz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-molecule; Protein; NHEJ; Dynamic; DNA repair; HR; Biomolecule interactions; Microscopy; Fluorescence; Nanofluidics;

    Sammanfattning : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. LÄS MER
