RNA biogenesis and genome homeostasis



Guaranteeing genome integrity while ensuring gene expression is a permanent challenge in living cells: while the regulated production of messenger RNAs is critical for the establishment of gene expression patterns, it can compete with the maintenance and the duplication of chromosomes. In this context, our team explores the mechanisms that keep in check the different stages of mRNA metabolism, from their synthesis in the nucleus to their export and translation in the cytoplasm. We are specially willing to understand:

– how mRNA biogenesis is synchronized with other DNA-dependent molecular transactions, by counteracting the formation of genotoxic DNA:mRNA hybrids (or R-loops);

– how these processes are spatially organized, in particular with respect to nuclear pores, the macromolecular complexes ensuring the transit of mRNAs out of the nucleus.

To address these questions, the integrative approach adopted by our team combines systematic and mechanistic approaches in a unicellular model eukaryote, the yeast S. cerevisiae .
