RESEARCH SUMMARY

Dr. Nussenzweig is a leading contributor to the study of mechanisms that maintain genomic stability and prevent cancer. His laboratory has elucidated many fundamental features of DNA damage and repair proteins and revealed the critical role they play in both normal and pathogenic states. Ongoing studies have emphasized the importance of DNA repair pathways as drivers of specific hematological malignancies and as contributors to chemoresistance/sensitivity in breast and ovarian cancers. The goal of his program is to use hypothesis-driven approaches to develop therapeutic strategies in the treatment of cancers.

Research

Genomic instability is a hallmark of cancer. Central to a cell's ability to maintain genomic stability are systems that monitor and repair DNA double strand breaks (DSBs). DSBs occur during normal DNA replication, in response to chemotherapeutic agents, and during physiological reactions including meiotic recombination in germ cells and antigen receptor rearrangements in lymphocytes. If not rapidly and faithfully repaired, DSBs can also be substrates for aberrant chromosomal translocations, which promote cancer. The focus of the Recombination Unit is to understand the mechanisms by which all cell types monitor and repair DSBs

Protocol for END-seq

An unbiased and genome-wide approach that maps DNA double-strand breaks (DSBs) with precision and sensitivity. END-seq provides a snapshot of DNA ends genome-wide, which can be utilized for understanding genome-editing specificities and the influence of chromatin on a variety of physiological and pathological processes.

Inside the nucleus, DNA is packed in highly complex structures that help to control which genes are on and off each time. In this video abstract, we explain how this intricate architecture makes specific DNA sites more susceptible to breaks that, if not properly fixed, can lead to cancer.
