DNA repair/chromatin remodeling in cancer

figure_mitosis-f2de0.png

Two teams, among the groups working on cancer at IPBS, investigate DNA transactions in pathological (ionizing radiations and clastogenic chemotherapeutic drugs) and physiological settings (antigen receptor rearrangements). Their respective projects highly benefit from collaborations with other IPBS teams specialized in NMR, structural biology and computer simulation, and from in-house core facilities such as proteomics, advanced light microscopy (two-photon microscopy), and animal facilities. 
In order to strengthen this research topic at IPBS, we are looking for a junior group leader using cutting-edge approaches in the DNA damage response (DDR) area, connected with cancer through epigenetics, transcriptional regulation, DNA repair pathologies, chromosomal translocations, DDR-based drug discovery, or tumor resistance to clastogenic agents.
