  1. 1. Gene therapy tools: oligonucleotides and peptides

    Författare :Jonas Eriksson; Ülo Langel; Jens Kurreck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gene therapy; oligonucleotide; peptide; RNA-cleaving deoxyribozyme; deoxyribozyme; DNAzyme; cell-penetrating peptide; CPP; enzyme; enzyme kinetics; kinetic assay; assay; telomerase; telomerase inhibitor; imetelstat; GRN163L; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Genetic mutations can cause a wide range of diseases, e.g. cancer. Gene therapy has the potential to alleviate or even cure these diseases. LÄS MER

  3. 2. Mutational Analysis and Redesign of Alpha-class Glutathione Transferases for Enhanced Azathioprine Activity

    Författare :Olof Modén; Bengt Mannervik; Mikael Widersten; Kenneth Tew; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allelic variants; azathioprine; bioactivation; chimeric mutagenesis; directed evolution; DNA shuffling; enzyme engineering; glutathione transferase; GST; lysate screening; molecular docking; multiple alignment; multivariate analysis; polymorphism; principal component analysis; prodrug; prodrug activation; protein engineering; protein redesign; reduced amino acid alphabet; saturation mutagenesis; semi-rational enzyme engineering; site-directed mutagenesis; structure-activity relationship; structure-based redesign; Biokemi; Biochemistry;

    Sammanfattning : Glutathione transferase (GST) A2-2 is the human enzyme most efficient in catalyzing azathioprine activation. Structure-function relationships were sought explaining the higher catalytic efficiency compared to other alpha class GSTs. LÄS MER

  4. 3. Gene therapy by enzyme replacement for Parkinson’s disease Optimization of continuous DOPA delivery and development of a candidate vector for clinical application

    Författare :Tomas Björklund; Brain Repair and Imaging in Neural Systems (BRAINS); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; Parkinson’s disease; L-DOPA; dyskinesia; GTP cyclohydrolase 1; tyrosine hydroxylase; dopamine; gene therapy; enzyme replacement; gene regulation; aromatic L-amino acid decarboxylase;

    Sammanfattning : The introduction of L-DOPA pharmacotherapy revolutionized the treatment of Parkinson’s disease close to fifty years ago. Before the discovery of dopamine as a neurotransmitter and its involvement in the disease, these patients had very little aid from medication and were bound to a life without movement. LÄS MER

  5. 4. Novel strategies for enzyme replacement with gene therapy in models of Parkinson’s disease

    Författare :Erik Cederfjäll; Brain Repair and Imaging in Neural Systems (BRAINS); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AAV vectors; dopamine; enzyme replacement; gene regulation; GTP cyclohydrolase 1; L-DOPA; tyrosine hydroxylase; Parkinson’s disease;

    Sammanfattning : Parkinson’s disease is a brain disorder characterized by loss of dopaminergic neurons in the midbrain, resulting in the characteristic motor symptoms: resting tremor, rigidity, akinesia and postural instability. Symptomatic treatment is based on reconstituting the loss of dopamine in the brain, primarily by oral administration of its precursor L-DOPA. LÄS MER

  7. 5. Vector development for suicide gene therapy

    Författare :Alar Aints; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Suicide gene therapy; VP22; selection markers; Ouabain resistance gene; GvHD; retroviral gene transfer;

    Sammanfattning : Gene therapy is used to treat conditions that arise from errors in the genetic makeup of cells either congenital diseases resulting from a deletion or mutation in a gene or malignant diseases where genetic regulation mechanisms have been deranged. Suicide gene therapy is one of several gene therapeutic approaches to treat cancer. LÄS MER
