Summary
Breast cancer strikes one in 8 women by age 85 and is a major cause of morbidity and mortality. Despite recent improvements, the immense breast cancer burden demands new strategies that will radically improve patient outcomes. This project will address a hallmark of cancer: evasion of apoptosis. Understanding the molecular events that promote tumour survival and resistance to therapy represents a key area in cancer biology that has yet to be properly applied to breast cancer.
Cell Survival Pathways As Potential Targets In Breast Cancer

Summary
Cancer cells are characterised by their capacity for relentless growth, survival and evasion of cell death. This proposal will use patient derived xenograft models of primary breast cancer to test the hypothesis that addition of BH3-mimetics could improve response to anti-HER2 therapy. This technique involves transplantation of patient tumours into immune-compromised mice. This represents a useful method for testing new agents.
Deciphering Breast Cancer Heterogeneity To Improve Breast Cancer Outcomes

Summary
Breast cancer is a very heterogeneous disease. Patients are often treated in a ‘one size fits all’ approach, but response to therapy remains quite disparate. To better personalise therapy, there is a pressing need to define the precise cell types and initiating genetic events that give rise to breast cancer. This application is focussed on understanding the molecular and cellular origins of breast cancer, with the potential of identifying new prognostic markers and therapeutic targets.
Prof Lindeman's laboratory, co-headed with Dr Visvader, has played an influential role in the identification of mammary stem and progenitor cells, elucidation of the mammary epithelial cell hierarchy and gaining insights into how female hormones regulate mammary gland development and cancer. In parallel, I have established translational research platforms such as patient-derived tumour xenograft (PDX) models, which offer powerful preclinical models to test new drugs.
