Ovarian cancer is frequently fatal and an extremely distressing cause of death in women. Our research program draws on the Australian Ovarian Cancer Study (AOCS), involving over 2000 women with ovarian cancer to investigate the genetic causes, and molecular changes that control cancer growth and response to therapy. The program is part of Australia’s $27m commitment to the International Cancer Genomics Consortium, an ambitious, worldwide effort to map the cancer genome.
Manipulating Oncogenic-signalling Pathways In The Genesis And Treatment Of Melanoma

Summary
Melanoma is a major Australian health problem. It is the third most common cancer in men and women and has a disproportionately heavy impact on productive years of life. The use of small molecule inhibitors is the most promising strategy for treating melanoma. In this project, we will examine the mechanisms of resistance to this class of drugs and define new drug targets by examining the molecular-circuitry is damaged in melanomas. This work will greatly accelerate the development of new therapi ....Melanoma is a major Australian health problem.

Cancer Genetics, Epigenetics And Targeted Therapies

Funding Amount
$873,684.00
Summary
I aim to gain greater insight into how blood cancers arise and how we should ultimately treat patients with these diseases. I will identify the genetic defects that underpin the development of blood cancers, how these genetic defects de-regulate gene expression through so-called “epigenetic” changes to allow these abnormal blood cells grow and survive. I will test the activity of small molecules that interfere with the cancer-causing epigenetic and signaling pathways in experimental models.
Discovering How MicroRNAs And CircRNAs Control Cancer Metastasis

Funding Amount
$763,845.00
Summary
Most cancers arise from epithelial cells, and most deaths from these cancers are due to the transition of the cancer to an invasive form, that can invade tissues and establish secondary cancers (metastases). Our work will focus on understanding how recently discovered gene regulators, called microRNAs and circular RNAs, control changes in cancer cells to allow them to progress to invasive, metastatic forms and use this knowledge to find ways to block the process.
Cancer remains a significant clinical problem and causes considerable morbidity and mortality in society. Prof Maria Kavallaris is an international leader in cancer biology, therapy and the development of less toxic therapies for cancer using nanotechnology. Her vision is to build a leading program of applied research to develop treatments for aggressive disease that will reduce the impact and improve the outcomes for cancer patients.
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.
Regulation Of Nucleocytoplasmic Transport; Role In Health And Disease

Funding Amount
$823,008.00
Summary
Transport into and out of the nucleus is central to the function of the cells from complex organisms such as mammals. This research program aims to improve understanding of nuclear transport and its regulation in the context of infection by medically relevant viruses, as well as in the context of cancer, and normal cell growth/development. It will contribute to developing new anti-viral therapeutics/vaccines, drug delivery strategies for cancer, and understanding causes of male infertility.
Structural Studies Of The Molecular Machinery Regulating Cell Death

Funding Amount
$638,517.00
Summary
Our bodies use a process called Programmed Cell Death to remove unwanted or dangerous cells. This work aims to understand the machinery that regulates this process at the molecular level. These insights will inform the development of drugs aimed at either initiating cell death when required, for example in cancer, or at inhibiting it when excessive cell death causes disease.
I study hormone action at the molecular level, particularly that of growth hormone action. I focus on the mechanism of activation of its receptor, notably as a target for cancer therapy, since growth hormone is necessary for the progression of many types of cancer. The ability of growth hormone to activate neural stem cells for a prolonged period in response to voluntary exercise is also a key interest. So too is the 40% extension of lifespan in mice after genetically deleting the growth hormone ....I study hormone action at the molecular level, particularly that of growth hormone action.

Rob Ramsay has had a long standing research commitment to understanding bowel and breast cancer using mouse models with defined genetic defects. These sophisticated models replicate various stages of cancer development and some have profound effects on normal tissue biology. He also uses molecular tools to investigate how genes are controlled. These approaches are providing direct input into the development of therapeutic agents for cancer treatment.
