DNA repair, damage signaling and carcinogenesis.

The First joint meeting of the German DGDR (German Society for Research on DNA Repair) and the French SFTG (French Society of Genotoxicology) on DNA Repair was held in Toulouse, France, from September 15 to 19, 2007. It was organized by Lisa Wiesmüller and Bernard Salles together with the scientific committee consisting of Gilbert de Murcia, Jean-Marc Egly, Frank Grosse, Karl-Peter Hopfner, Georges Iliakis, Bernd Kaina, Markus Löbrich, Bernard Lopez, Daniel Marzin and Alain Sarasin. This report summarizes information presented by the speakers (invited lectures and oral communications) during the seven plenary sessions, which include (1) excision repair, (2) DNA repair and carcinogenesis, (3) double-strand break repair, (4) replication in repair and lesion bypass, (5) cellular responses to genotoxic stress, (6) DNA repair machinery within the chromatin context and (7) genotoxicology and testing. A total of 23 plenary lectures, 32 oral communications and 66 posters were presented in this rather intense 4 days meeting, which stimulated extensive discussions and highly interdisciplinary scientific exchanges among the approximately 250 participants.
