Research description

We are interested in understanding of the links between deficiencies in the DNA damage response and the molecular nature of disease.

Human cells repair thousands of DNA lesions daily. The majority of lesions arise from the intrinsic chemical instability of DNA and include single-strand breaks and base modifications. Unrepaired lesions can obstruct DNA replication, leading to mutations and toxic DNA double-strand breaks. In non-proliferating cells (for example, post-mitotic neurons) damaged DNA bases and single-strand breaks can block transcription, leading to cell death and disease. In particular, defects in DNA repair are often linked to cancer and progressive neurological disorders, although their precise roles in the malignant and neurological phenotypes remain elusive.
