DNA Repair
We work on deciphering the mechanisms of the initiation of DNA replication in human cells using cell biology approaches, as well as ATR and WEE1 inhibitors. DNA replication remains one of the main targets of cancer therapies since cancer cells generally proliferate faster and are more prone to replication stress. Our main research interests are i) identifying novel replication initiation factors, ii) deciphering the non-catalytic role of DNA polymerase epsilon in the initiation of DNA replication in human cancer and non-cancer cells, iii) alterations of the replication proteins in cancers. We use auxin-inducible degron systems and split Turbo-ID proteomic screens, among other innovative methods, to identify key steps in human replication initiation that can be potential future targets for cancer therapies.
