1. Development of benzoquinoquinoxaline derivatives as triplex-specific probes : Recognition of DNA structures at repeats sequences
Abstract : Repeat sequences are associated with several human diseases, such as Friedreich’s ataxia, polycystic kidney disease and cancer. These sequences can form non-B-DNA structures, including triplex (H-DNA) DNA, and are associated with genomic instability and altered gene expression. READ MORE

2. Fixation of Functionalized DNA Nanostructures
Abstract : This thesis features results from two different studies on a fully addressable non-repetitive network on the nanometre scale, assembled by synthetic DNA molecules. A bio-inspired molecular approach, based on principles of self-assembly, has brought about a paradigm shift in nanoscience, from a top-down to a bottom-up perspective. READ MORE

3. Structural Adaptation of DNA to Small Ligands and Recombination Proteins
Abstract : In order to contribute to the understanding of mechanisms of recognition in nucleic acid systems, the interaction of DNA with a variety of ligands, representing different cases of adaptation of the double-helix structure, was studied using flow linear dichroism (LD), circular dichroism (CD), fluorescence and absorption spectroscopic techniques. A chiral hydrophobic metal complex, [Ru(dpphen)3]2+ was examined, since this had been reported to be the most efficient molecule to discriminate DNA handedness. READ MORE

4. Bottom-up Fabrication of Functional DNA Nanostructures
Abstract : This thesis demonstrates bottom-up fabrication of a fully addressable non-repetitive network on the nanometer scale, assembled by synthetic DNA molecules. Each side constitutes a unique sequence of 10 bases, i.e. 3. READ MORE

5. Studies on nuclear factor 1 binding to nucleosomal DNA
Abstract : The organisation of DNA into chromatin will influence on transcriptional regulation. The first event in transcriptional activation is the binding of transcription factors to specific binding sites in the regulatory regions of the gene. READ MORE
