Research Summary

Germline heterozygous mutations in BRCA1 or BRCA2 genes predispose affected individuals to several types of cancer, including breast, ovarian, prostate and pancreatic. Functional BRCA1 and BRCA2 tumour suppressors play key roles in DNA replication, where they promote stability and restart of stalled replication forks. Moreover, they mediate HR repair, the accurate DNA repair pathway, essential for preserving genome integrity. Consequently, cells with compromised BRCA1/2 function have slow rates of replication and accumulate stalled and damaged replication forks. These pathologies lead to replication-associated DNA damage and genome instability, a signature of BRCA1/2-mutated cells and tumours. Work conducted in my laboratory aims to unravel the mechanisms underlying replication failure in BRCA1/2-deficient cells and how this knowledge can be exploited for the development of novel therapeutic strategies.

Biography

Dr. Madalena Tarsounas obtained her PhD at York University in Toronto, Canada (1999). She then undertook postdoctoral training at the Clare Hall Laboratories of the CRUK London Research Institute (1999-2005), funded by postdoctoral fellowships from the European Molecular Biology Organization (EMBO) and the Breast Cancer Campaign. Dr. Tarsounas joined the CRUK/MRC Oxford Institute for Radiation Oncology in December 2005 as a CRUK Junior Group Leader and was promoted to CRUK Senior Group Leader position in December 2011. In 2015 she became University of Oxford Professor of Molecular and Cell Biology.

In 2010, Dr. Tarsounas was elected EMBO Young Investigator. In 2011, she initiated the EMBO Conference Series on ‘DNA damage responses in cell physiology and disease’ held in Cape Sounio, Greece, which has since become a biennial international event. In 2017, Prof. Tarsounas was awarded the prestigious Mayent-Rothschild Prize for her sabbatical stay at the Institute Curie in Paris.

Work in Prof. Tarsounas' laboratory is funded by CRUK, MRC, Breast Cancer Now and EMBO, as well as an Horizon 2020 Innovative Training Network Award.
