Aberrant DNA replication is one of the leading causes of mutations and chromosome rearrangements associated with several cancer related pathologies, and several chemotherapeutic strategies employ agents that induce replication stress in the attempt to selectively target highly proliferating cancer cells. Our group studies the mechanisms that operate in eukaryotic cells to maintain replication fork integrity. In particular, we use a combination of cellular, biochemical and structural approaches to define the role of RecQ helicases in this process. Our recent studies provided new mechanistic insight into the role of RecQ helicases in replication stress response, offering new molecular perspectives to potentiate chemotherapeutic regimens based on replication inhibitor treatment.
