16. Biophysical studies of DNA binding – by the large filament-forming protein Rad51 and the small minor-groove binder Hoechst 33258
Sammanfattning : Mechanistic insight into the nature of DNA-binding ligands is crucial for both drug development as well as understanding more complex biological reactions that take place in the cell. In this Thesis, two rather different DNA-binding molecules are considered: 1. LÄS MER
17. Development of novel DNA vaccine and immunotherapeutic approaches
Sammanfattning : Many potential DNA vaccination and immunotherapeutic strategies has been explored in both animal models and human settings in recent years. However, the failure of efficient and safe method development suggests that it is time to rethink, since more innovative approaches are needed for better control of infection and immunotherapy.

18. Nucleic acid delivery : reports from the search of the magic bullet
Sammanfattning : Gene therapy is regarded as one of the most promising therapeutic approaches, since it has the potential to treat disorders by correcting malformations at the nucleic acids level rather than proteins, as opposed to conventional medicine. However, for non-viral gene therapy to successfully fulfill the requirements associated to the “magic bullet” has proven difficult. LÄS MER
19. Peptide nucleic acid conjugates as artificial ribonucleases : Cu2+ and Zn2+-dependent PNAzymes
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.

20. Applications of DNA origami encoded nanoscale patterns
Sammanfattning : It was almost four decades ago when the recognition of DNA’s potential use as a programmable, self-assembling building material for nanostructures led to the birth and rapid expansion of the field of DNA nanotechnology, but it was two decades later when the development of the DNA origami technique initiated the widespread use of DNA based nanoconstructs through the simplification of the design process and the reduction of the required control over the quality and stoichiometry of the assembly components by using a single-stranded “scaffold” DNA and a set of “staple” oligonucleotides that “fold” the mentioned scaffold DNA into a predesigned shape by binding different regions of the scaffold strand together. This robust approach not only permitted the construction of intricate two- and three-dimensional structures, but it also allowed the design and fabrication of molecular patterns with unprecedented accuracy as each functionalizible component’s relative position in the DNA origami structure is known to nanometer precision.
