Functional organization of the mammalian genome
Research summary:
Copying and decoding the genomic information in a timely and accurate fashion is essential for life. Both tasks (DNA replication and transcription) are remarkably complex in scale and regulation, and the molecular machineries involved in them translocate on the same DNA template, often in opposite directions and at different rates. This impose cells to employ efficient mechanisms to coordinate both processes. Failure of these mechanisms can lead to catastrophic effects on genome stability and cell viability. Very likely, dealing with this potential conflicts strongly influences many key parameters of cellular function, including genome organization, chromatin structure or mutagenesis rates. Unraveling the intricate relationship between the processes of replication and transcription and the impact of this crosstalk on genome homeostasis is the central goal of our research. Besides its relevance for fundamental biology, this knowledge might have important implications in disease scenarios, especially in cancer cells where upregulation of transcription is suspected to be a major contributor of oncogene-induced replication stress. To address this general objective we integrate multigenomic approaches with quantitative molecular biology, genetic engineering, and synthetic activators.
