DNA is frequently damaged by exposure to UV radiation, oxidative stress and mutagenic chemicals. If DNA damage accumulates, it can lead to cell death or even cancer. Consequently, cells must be highly efficient at detecting and repairing DNA damage in order to survive. We study the molecular mechanisms cells use to repair damaged DNA, avoid genome instability when replicating DNA, and prevent mistakes when producing proteins. By understanding how they keep their genome intact, we hope to find new strategies for preventing cancer and slowing ageing.
