  2. 1. Dendrimer-mediated gene delivery: Effect of polymer structure on cellular response

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene therapy; DNA condensation; cationic polymers; toxicity; non-viral vector; drug delivery; polyplex; PAMAM dendrimers;

    Abstract : The delivery of nucleic acids to cells, in vitro and in vivo, is becoming a realistic approach for intervention with gene expression at a molecular level. It can be used to repair malfunctioning genes or to introduce new functionalities, with the most important application being clinical treatment of human diseases. READ MORE

  4. 2. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis

    Author : Moataz Dowaidar; Ülo Langel; Sandrine Sagan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; magnetic nanoparticles; graphene oxide; autophagy; siRNA; SCO; QSAR; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. READ MORE

  5. 3. Condensation of DNA for Gene Delivery: Studies on Vector-Nucleic Acid Interactions and Transfection Efficiency

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dendrimer; endocytosis; uptake; gene delivery; optical spectroscopy; structure-activity relationship; DNA; cell-penetrating peptide;

    Abstract : This thesis concerns the delivery of nucleic acids into cells and tissues with the aim to change or correct gene expression. The field of gene delivery has the ultimate goal of producing genetic drugs for clinical applications, and the activity in this area is intense although so far the use is limited to research purposes.

  6. 4. Interactions of the Cell-Penetrating Peptide Penetratin with Model Membranes and Live Cells

    Author : Daniel Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antisense; antennapedia homeodomain; delivery vector; cell-penetrating peptide; protein transduction; uptake; membrane translocation; penetratin; confocal microscopy; vesicle;

    Abstract : The delivery of large, hydrophilic molecules, such as proteins and oligonucleotides, to the cytoplasm and nucleus of cells is problematic due to their generally low plasma membrane permeability. With the identification of a number of cell-penetrating peptides, capable of mediating non-endocytotic, intracellular delivery of macromolecular cargos, this obstacle now seems surmountable.

  7. 5. Acylated cell-penetrating peptides for nucleic acid delivery

    Author : Tönis Lehto; Ülo Langel; Eric Johnston; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptides; nucleic acid delivery; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : In recent decades many new methods have been developed to cure or treat genetical disorders such as cancer, viral infections or inheritable diseases. The problem is that the nucleic acids and their synthetic analogs, oligonucleotides, are not able to cross the cell membrane due to their physicochemical properties like high negative charge and size.
