  1. 11. Peptide nucleic acid conjugates as artificial ribonucleases : Cu2+ and Zn2+-dependent PNAzymes

    Författare :Olivia Luige; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Synthetic modified oligonucleotides are gaining momentum as powerful therapeutic tools used in the treatment of life-threatening diseases. Degradation of disease-related RNA sequences is one of the goals achieved with oligonucleotide therapeutics, albeit the currently available technologies rely on the recruitment of endogenous enzymes, RNase H or RISC, limiting the chemical architecture of oligonucleotide drugs.

  3. 12. Investigation of RNase P active site residues and catalytic domain interaction

    Författare :Guanzhong Mao; Leif Kirsebom; Roland Hartmann; Britt-marie Sjöberg; Anders Byström; Anthony Forster; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNase P; Ribozyme; PRORP; Induced fit model; RNase P-pre-tRNA interaction; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : RNase P is an essential endoribonuclease responsible for the maturation of the tRNA 5’end. The RNase P family encompasses the ribozyme based, RNase P RNP, and proteinaceous RNase P (PRORP). The ribozyme based RNase P is widely distributed in most species while PRORP has so far mainly been found in some eukaryotic cells. LÄS MER

  4. 13. Human immunodeficiency virus type 1 proteinase : regulation of function and catalytic activity

    Författare :Laura Goobar-Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : HIV-l proteinase activity is a prerequisite for viral replication, and one of the main targets for anti-HlV therapy. Although potent proteinase inhibitors are currently being approved for treatment of AIDS patients, these drugs are unlikely to provide treatment which can give patients a life of normal quality and duration.

  5. 14. Hematopoietic Serine Proteases from the Mast Cell Chymase and Tryptase Loci - a Functional and Evolutionary Analysis

    Författare :Jenny Reimer; Lars Hellman; Gunnar Nilsson; Sara Wernersson; Göran Andersson; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; immune system; mast cell; basophil; mast cell chymase locus; multigene tryptase locus; serine protease; evolution; Cell- och molekylärbiologi;

    Sammanfattning : Mast cells are key effector cells in allergic and inflammatory diseases. However, their primary role is most likely in host defence against parasitic and bacterial infections. Mast cells are a particularly rich source of serine proteases. LÄS MER

  7. 15. Resistance to activated protein C a novel risk factor for venous thrombosis

    Författare :Peter Svensson; Malmö Klinisk koagulationsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APC resistance; mutation; venous thrombosis; blood coagulation; Protein C; factor V; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

    Sammanfattning : Activated protein C resistance (APC resistance) is the most common hereditary condition associated with venous thrombosis. The syndrome known as APC resistance is perfectly linked to a mutation in the gene coding coagulation FV (FV:Q506) mutation changing Arg 506 to Gln in the APC cleavage site. LÄS MER
