Replication and Genome Stability Group


Breast cancer is the most common female cancer (1/9 women) and the second highest cause of cancer-related female death. A defining feature of breast cancer cells is uncontrolled proliferation and growth. Our group investigates how breast cells lose control of proliferation and how this alters the DNA of cancer cells.  We use a combination of traditional laboratory methods, genomics and bioinformatics to address this question. We have made significant findings on potential biomarkers for cancer, especially drug-resistant disease, and how to tailor hormone and chemotherapy treatments for breast cancer cells.

Our research focus is:

  1. How cyclin E2, a protein that drives proliferation, can alter how cells respond to DNA damage to make cells more unstable;
  2. The way that proliferation pathways in the cell intersect with other processes (growth, DNA transcription) and can be disrupted in cancer;
  3. Genomic instability in endocrine resistant breast cancer.
