  1. 1. Oligonucleotide Complexes with Cell-Penetrating Peptides Structure, Binding, Translocation and Flux in Lipid Membranes

    University dissertation from Stockholm : Department of Neurochemistry, Stockholm University

    Author : Luis Daniel Ferreira Vasconcelos; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; Large unilamellar vesicle; Membrane perturbation; Endosomal escape; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The ability of cell-penetrating peptides to cross plasma membranes has been explored for various applications, including the delivery of bioactive molecules to inhibit disease-causing cellular processes. The uptake mechanisms by which cell-penetrating peptides enter cells depend on the conditions, such as the cell line the concentration and the temperature. READ MORE

  2. 2. Characterization of nucleic acid delivery with fatty acid modified cell-penetrating peptide nanoparticle formulations

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Tõnis Lehto; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transfection; gene delivery; oligonucleotide; complexes; non-viral; in vivo; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Recent advances with techniques used for manipulating gene expression have brought us to an era where various gene therapeutic approaches are becoming common therapeutic tools for many previously incurable diseases. The main factor impeding the wider translation of gene therapy is that the active pharmaceutical ingredients used for interfering with gene expression are based on nucleic acids and synthetic oligonucleotides and such molecules do not readily reach their intracellular targets due to their physicochemical properties and therefore they require delivery vectors to cross the cell membrane.

  3. 3. Kinetic assays for RNA-cleaving deoxyribozymes and other nucleases

    University dissertation from Stockholm : Department of Neurochemistry

    Author : Jonas Eriksson; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : In this thesis two different assays for real-time RNA-cleaving deoxyribozyme and general nuclease kinetics are presented. Previous publications on nuclease kinetic assays have been riddled with drawbacks of labeling, discontinuity, cost etc. READ MORE

  4. 4. Caspase activation in human neuroblastoma cells: mechanisms and spatiotemporal aspects

    University dissertation from Stockholm : Department of Neurochemistry

    Author : Elena V. Ivanova; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; apoptosis; caspase; local caspase activation; neurodegeneration; tau-anchored FRET sensors; tAFS; cancer; neuroblastoma; TNF-related apoptosis inducing ligand; TRAIL; protein kinase C; PKC; X-linked inhibitor of apoptosis protein; XIAP; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Apoptosis is one of the modes of programmed cell death, in which several members of the caspase family of proteases play the central role. However, activation of apoptotic caspases does not necessarily lead to cell death. READ MORE

  5. 5. In-silico design of peptide-based transfection systems, in-vitro validation, and up-take pathways investigation

    University dissertation from Stockholm : Department of Neurochemistry, Stockholm University

    Author : Moataz Dowaidar; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; QSAR; PepFect; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Cell-penetrating peptide-based transfection systems (PBTS) are a promising group of drug delivery vectors. Cell-penetrating peptides (CPPs) are short cationic peptides that are able of transporting cell non-permeant cargos into different cell types. READ MORE
