Abstract (sommario):

Nucleic acids and proteins, some of the building blocks of life, are not static structures but highly dynamic entities that need to interact with one another to meet cellular demands. The work presented in this thesis focuses on the application of highly sensitive fluorescence methods, both at ensemble and single-molecule level, to determine the dynamics and structure of specific biomolecular interactions with nanometer resolution and in temporal scales from nanoseconds to minutes, which includes most biologically relevant processes. The main aims of my PhD can be classified in three areas: i)

Abstract (sommario):

Protein-DNA interactions govern the fundamental cellular processes of DNA replication, transcription, repair, and chromosome organisation. Despite their importance, the detailed molecular mechanisms of protein-DNA interactions and their organisation in the cell remain elusive. The complexity of molecular biology demands new experimental concepts that resolve the structural and functional diversity of biomolecules. In this thesis, I describe fluorescence methods that give a direct view on protein-DNA interactions at the single-molecule level. These methods employ photoswitching to control the n

Abstract (sommario):

Small molecules are known to play critical role in understanding most biological mechanisms of cells and organisms. Some examples, such as RNAs, peptides and drug molecules, etc., work by modulating cellular function, but with unknown modes. In most cases, these actions involve the small molecule interacting with proteins serving various functions. In recent years, much effort has been made in the investigation of interactions between small molecules (ligands) and target proteins. In our laboratory, a new technique termed Dynamic Isoelectric focusing Anisotropy Binding Ligand Assay (DIABLA) is

This thesis describes different aspects of protein interactions. Initially the function of peptides and their conjugates with small molecule inhibitors on the surface of Human Carbonic Anhydrase isoenzyme II (HCAII) is evaluated. The affinities for HCAII of the flexible, synthetic helix-loop-helix motif conjugated with a series of spacered inhibitors were measured by fluorescence spectroscopy and found in the best cases to be in the low nM range. Dissociation constants show considerable dependence on linker length and vary from 3000 nM for the shortest spacer to 40 nM for the longest with a mi

La méthode des fragments consiste à cribler un petit nombre (< 10000) de composés organiques de faible poids moléculaire (< 300 Da) afin de détecter ceux qui se lient à la cible (protéine ou acides nucléiques).

Abstract (sommario):

Single-stranded DNA binding proteins (SSB) bind to single-stranded DNA (ssDNA) that is generated by molecular machines such as helicases and polymerases. SSBs play crucial roles in DNA translation, replication and repair and their importance is demonstrated by their inclusion across all domains of life. The homotetrameric E. coli SSB and the heterotrimeric human RPA demonstrate how SSBs can vary structurally, but all fulfil their roles by employing oligonucleotide/oligosaccharide binding (OB) folds. Nucleofilaments of SSB proteins bound to ssDNA sequester the ssDNA strands, and in doing so pro

Abstract (sommario):

Fundamental to all biological processes is the interplay between biomolecules such as proteins and nucleic acids. Studies of interactions should therefore be more informative than mere detection of expressed proteins. Preferably, such studies should be performed in material that is as biologically and clinically relevant as possible, i.e. in primary cells and tissues. In addition, to be able to take into account the heterogeneity of such samples, the analyses should be performed in situ to retain information on the sub-cellular localization where the interactions occur, enabling determination

Hypoxia-inducible factor (HIF) is a heterodimeric, oxygen-dependent, transcription factor that regulates the cellular response to hypoxia by directing the expression of multiple genes, such as those involved in angiogenesis and glucose transport.

There are two predominant isoforms of HIF, HIF-1 and HIF-2, formed by heterodimerisation of HIF-1 or HIF-2, respectively, with HIF-1. The dimerisation of the two subunits is necessary for DNA

Both simple ligands and drug conjugates were synthesized and tested to assess their biological activity. In cancer therapy, peptides and peptidomimetics targeting integrins are employed as carriers to deliver cytotoxic drugs at the tumor site, taking advantage of integrin over-expression on the surface of tumor cells. Within this frame, synthetic efforts have been focused on the synthesis and on the conjugation to the cytotoxic agent paclitaxel of isoDGR-based integ

Abstract (sommario):

Genomic DNA is the template of life - the entity which is characterized by a self-sustaining anatomical development, regulated signaling processes, the ability to reproduce and to respond to stimuli. Through what is classically known as the central dogma, the genome is transcribed into mRNA, which in turn is translated into proteins. The proteins take part in most, if not all, cellular processes, and it is by unraveling these processes that we can begin to understand life and disease-causing mechanisms. In vitro and in vivo assays are two levels at which protein communication may be studied, a
