Summary
Whole genome sequencing studies of human breast tumours identified a handful of common significantly mutated genes, all previously linked to breast cancer, except one, CBF?. Preliminary data from our lab now show that CBF? may be a new regulator of human breast cancer and metastasis. Using mice with altered CBF? levels, breast cancer models and human patient cohorts, this study aims to identify a novel role for CBF? as a new regulator of human breast cancer and potential therapeutic target.

Summary
Despite reliable methods of prostate and breast cancer diagnosis there remains considerable uncertainty as to whether the detected disease will have a significant impact on a patient’s quality of life. This uncertainty is largely due to the inability of current detection methods to show the extent of disease. This project will address this problem by developing new MRI methods that directly measure the microscopic tissue properties that define cancer.
Endocrine Therapy Tolerance As A Cancer Cell Survival Mechanism For Late Recurring Breast Cancer

Summary
~25% of breast cancer deaths are attributable to cancers that have failed endocrine therapy and recur >5 years after primary diagnosis. These cancers are not well understood because their long latency makes them difficult to study. We have new models of this disease that identify a “therapy tolerant” population, and this is likely to re-emerge to cause late recurrence. Our work could potentially identify new biological tests and therapeutic strategies to treat late recurring breast cancer.
Reduction Of Breast Lymphoedema Symptoms Secondary To Breast Cancer: A Randomised Controlled Trial

Summary
Breast lymphoedema is a consequence of treatment for breast cancer that is not typically discussed, despite more than 1/3 of women with lymphoedema reporting symptoms in the breast. To date, no study has investigated the impact of exercise on breast lymphoedema symptoms. The aim of this study is to determine if a general exercise program is safe, acceptable and effective in reducing symptoms for women with breast lymphoedema.
Identification Of Target Genes At Breast Cancer-risk Loci With Potential For Drug Repositioning

Summary
Genome wide association studies have been extremely successful at identifying regions of the genome associated with breast cancer risk. However, to fully translate this information to prevention and treatment of breast cancer, we need to understand the molecular mechanisms responsible for increasing breast cancer susceptibility, and the genes that are involved.
Determination Of The Cellular Origins Of Breast Cancer

Summary
Breast cancer is a highly heterogeneous disease with multiple molecular and histological subtypes. We propose to use novel genetically engineered mice to understand breast inter-tumoral heterogeneity by dissecting the cells of origin of breast cancer in vivo. Initially, we will examine whether long-lived stem or progenitor cells are the targets of breast carcinogenesis induced by a progesterone derivative using our state-of-the-art multi-coloured reporter models to track the cells in vivo.
The Oligoadenylate-RNAseL Pathway May Provide A Specific And Low Toxicity Approach To Therapy For Breast Cancer

Summary
We have discovered that a pathway used to fight viral infections can be triggered to produce massive cell death in the mammary gland. We hope to be able to trigger this response in breast cancers through the strategic combination of available drugs. If successful this project will establish a new therapeutic strategy for breast cancer.
Breast cancer is the most common malignancy among females which affects 1 in 8 women. Normal cells only divide when they receive a stimulus however cancer cells divide uncontrollably and are able to spread to other sites in the body, a process known as metastasis. We have identified a cancer suppressing gene which regulates cancer spread. This grant aims to characterise the mechanisms by which this gene controls cell movement and breast cancer spread.
Characterisation Of PI3-kinase-dependent Signalling Networks In Breast Cancer

Summary
Breast cancer affects 1 in 8 women in Australia. Cancer cells are able to spread to other sites in the body by a process known as metastasis which is the leading cause of breast cancer death. We have identified a gene which controls breast cancer growth and metastasis. This grant aims to elucidate the mechanisms by which this gene co-operates with another gene to regulate breast cancer growth and metastasis which thereby may affect disease outcome.
A Functional In Vivo ShRNA Screen For Regulators Of Breast Cancer Metastasis.

Summary
Breast cancer is generally incurable if detected after the tumour has spread to other organs. The genes driving the tumour cells to other sites have not been clearly resolved. This project aims to accelerate the discovery process by using a genome wide functional screen to identify genes that control the spread of breast cancer. If successful, this project could lead very quickly to identification of genes that might be good targets for new therapy against advanced breast cancer.
