Development and optimization of genome editing approaches

Here we are focusing on developing new strategies to optimize genome editing methods using TALE proteins and CRISPR/cas9 system and provide resources in the field (TACGENE Facility). We are characterizing the DNA repair mechanisms associated with nuclease driven genome modifications in order to improve the efficiency of the strategies. Our work includes the biophysical characterization of these sequence-specific DNA agents.

Biochemical and proteomic characterization of DNA repair complexes

We have developed a strategy to directly purify native nucleo-protein complexes and to identify the protein partners involved in these complexes, by mass spectrometry analyses. Thus we can identify new DNA repair proteins and complexes, and cellular activities are validated by using well established DNA repair reporters.

Molecular mechanisms driven chromosomal translocations in human cells and their role in oncogenesis*

This project focuses on understanding chromosomal translocation formation that can arise from two simultaneous DSBs on two heterologous chromosomes. We use site-specific nucleases such as ZFNs, TALENs or CRISPR/Cas9 to induce chromosomal translocations in human cells. The nucleases are directed toward genomic regions implicated in oncogenic translocations. Creating physiologically relevant translocations at endogenous loci, rather than ectopically provides us a physiological model to study translocation mechanisms and to understand the tumorigenesis associated with such chromosomal rearrangements.
