Summary
In breast cancer the spread of cancer (metastasis) to bone occurs frequently and causes significant problems including pain, fracture, immobility and paralysis. We have recently discovered that a drug, widely used in Japan and Korea for skin disorders, inhibits breast cancer growth in bone using animal model systems of this disease. This is a very exciting and novel finding. We will further investigate the potential of this drug and identify precisely how it works at the molecular level.
Tumour-associated Macrophages (TAMs) And Their Role In Breast Cancer Metastasis

Summary
Tumour-associated macrophages (TAMs) have been implicated in breast cancer spread. Tumour cell behaviour is influenced by the surrounding environment. This study will determine the relationship of TAMs to other cell populations, if the expression of the enzyme, u-PA, in non-tumour cells within the tumour environment is important for breast cancer spread, and whether TAM precursor white blood cells home to the primary tumour and-or to the site of tumour spread before the arrival of tumour cells.
Parathyroid Hormone-related Protein (PTHrP), Common Genetic Variants In The PTHrP Gene (PTHLH), And Breast Cancer Risk And Survival

Summary
In a partnership between Peter MacCallum Cancer Centre, St Vincent's Hospital, and The University of Melbourne, we are investigating the role of PTHrP, a peptide integral to the growth and spread of Cancer. Initially thought to facilitate cancer spread, recent studies suggest it may actually be protective. In a new approach, we will analyse new DNA databases and patient data from around the world. We hope to extend our understanding of PTHrP, and perhaps find novel drug and therapeutic targets.
Determining The Clinical Relevance Of Intratumour Heterogeneity In Breast Cancer And Its Relationship To Metastases Formation

Summary
Breast cancer metastasis is generally an incurable disease, yet it is not well-understood. This project aims to understand how cancer metastasises by using a novel and unique approach of analysing multiple regions from matched primary and metastatic tumours from breast cancer patients. Expected outcomes include identifying predictors of treatment resistance and resultant personalised management and therapeutic strategies to improve survival outcomes of breast cancer patients.
Linking Breast Development To Bone Metastasis: Role For The Osteogenic Transcription Factor Runx2 During Breast Carcinogenesis

Summary
Bone is the principle metastasis site of breast cancer and represents a major cause of morbidity and mortality. Runx2 is one potential candidate gene mediating breast cancer metastasis. Using mice with altered Runx2 levels and breast cancer models, this study will examine the role of Runx2 in breast cancer bone metastasis. Identification of a single gene that controls both breast and bone would open a new area of breast cancer research and a new gene against which therapies could be developed.
