Summary
This proposal aims to identify molecular markers that can be used to classify subtypes of particular cancers according to their prognosis and response to therapy. This will optimise selection of patients for the most appropriate treatment and lead to the development of new therapeutic strategies.

Summary
The ten scientific laboratories in this program have joined forces to investigate two ways in which tumours develop. Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers.

Both are of particular interest, because they suggest new ways in which cancer might be overcome. Most of our tissues are continually renewed throughout life by production of new cells. Therefore many of the old cells in each tissue must die off to maintain the proper cell numbers. To eliminate cells that are no longer needed or have become damaged, the body has developed a remarkable cell suicide process termed apoptosis. Unfortunately, however, occasionally a random accident to the genes in one of our cells prevents the machinery for apoptosis from being turned on. In that case, the cell will not die when it should and, by continually dividing, it may eventually give rise to a cancer. Since most cancer cells still retain most of the machinery for apoptosis, however, a drug that could switch on this natural cell death machinery would provide a promising new approach to cancer therapy. Identifying and developing such drugs is one major long-term goal of this program. The other focus of our program concerns stem cells. These are rare cells with the remarkable ability to generate an entire tissue. For example, one of our laboratories has identified stem cells that can generate all the cells in the breast. The almost unlimited regenerative capacity of stem cells has a built-in danger. If a stem cell acquires the ability to proliferate excessively, it can go on to form a tumour. Indeed, many cancer researchers now suspect that rare stem cells within a tumour cause its inexorable growth. If tumour growth is maintained by stem cells, it will be essential to develop new forms of therapy that target these rare cancer stem cells rather than merely the bulk of the tumour cells. This is another key long-term goal of our program.Read moreRead less

The main aim of this ' vertically integrated ' model was to develop new therapies to improve stroke outcomes. We developed a system to identify ' off-the-shelf ' compounds which protect the brain after stroke onset. This involves data assimilation (meta-analysis) in a unique way, an approach which has attracted attention internationally. We are also completing an important clinical trial using the clot dissolving agent tPA to extend the time during which the drug may be effective beyond the three-hours currently used. In the next phase of our program we plan to expand the basic science component to identify parts of brain cells (axons and dendrites) which may yield important information about new drugs to protect the brain. We will use our novel summary data technique to test drugs in animal models more appropriate to the human stroke paradigm than have been used in the past In clinical studies we will follow our theme of identifying new targets for therapy using sophisticated PET and MRI imaging techniques, both in patients who are at great risk of stroke recurrence after a minor warning stroke and those with stroke caused by bleeding within the brain. These studies will provide information about predictors of recurrent and worsening stroke which may be modified by new therapies. The final stage in identifying new therapies is the Phase III clinical trial. We will complete one of these in which the most appropriate drug preventing further strokes in a major new stroke subtype will be identified. Toward the end of the program, we will commence phase 3 studies of drugs we have selected as being most likely to protect the brain based on our animal experiments. The main benefit of this unique collaborative research model is to efficiently identify new therapies to reduce the burden of stroke, currently the second most common cause of death globally.Read moreRead less

The aim of the work is to develop vaccines or other biological prevention measures against each of these diseases and the problems that need to be solved are similar. The team includes senior experts on thebiology of infectious diseases with long histories of collaboration as well as younger members with impressive credentials that are new to the collaboration. The fourth theme of the work proposed is concerned with inventive new ways of making such vaccines by novelchemical methods. It has already been the subject of published collaborative work onstreptococcal disease and is equally applicable to the other themes.Read moreRead less

Doing regular physical activity is very important for maintaining good health. It helps to prevent weight gain, type 2 diabetes, heart disease and breast and colon cancer. Unfortunately, most Australian adults are not active enough for health benefits. Rates of overweight and obesity are increasing rapidly; more than 50% of Australian adults are above the healthy weight range. Rates of type 2 diabetes have doubled in the past 20 years. New ideas and practical tools are therefore needed to tackle these serious ‘diseases of inactivity’. To this end, Professors Neville Owen, Adrian Bauman and Wendy Brown will bring together innovative and practically useful scientific approaches drawn from psychology, epidemiology and exercise physiology. The approach is interdisciplinary – it combines theories and methods from their individual disciplines in an innovative manner, within a public health framework. Their research to date has developed better methods for measuring people’s exercise habits and has provided new insights into how personal, social and environmental circumstances can make people less active. They have also shown how to design and deliver wide-reaching programs for different social groups and evaluated their effectiveness. Their new research program will build on and significantly extend these ideas and approaches into new areas.For example, they will develop new measures of incidental physical activity and sedentary behaviour and will develop and test new, complex community interventions.Their new program will involve in-depth study of some of the most challenging researchproblems in an important and under-researched area of public health. They will further combine their disciplines and the skills of their research team in new, creative and practical ways, to answer important research questions about physical activity and population health. These ideas and approaches will be used to identify practical ways to help more people to be more physically active.Read moreRead less
