To study the genetic alterations that give rise to cancer. In particular, exploring how too little death of cells can lead to a tumour. If too few cells in a tissue die, a tumour may develop there. The team is exploring how the cell death process is normally controlled. They plan to characterise the molecules inside cells that determine whether a cell lives or dies and hope that better understanding of those molecules will help to explain how tumours arise.

They plan to characterise the molecules inside cells that determine whether a cell lives or dies and hope that better understanding of those molecules will help to explain how tumours arise. It could also lead to new drugs that can kill tumour cells more effectively by directly triggering the normal death switch of the cell.Read moreRead less
This program of research is firmly focussed on the basic mechanisms involved in normal functioning of cells and tissues, followed by a step by step process to understand the abnormal or the diseased. The disease states we are investigating involve the blood and blood vessels, and when there is malfunction it may contribute to conditions as diverse as atherosclerosis, thrombosis, inflammation and cancer. The program thus addresses the fundamentals of diseases which are responsible for most deaths ....This program of research is firmly focussed on the basic mechanisms involved in normal functioning of cells and tissues, followed by a step by step process to understand the abnormal or the diseased. The disease states we are investigating involve the blood and blood vessels, and when there is malfunction it may contribute to conditions as diverse as atherosclerosis, thrombosis, inflammation and cancer. The program thus addresses the fundamentals of diseases which are responsible for most deaths in our society. We will use technology which is proven to provide precise information, the molecular and biochemical processes responsible for cell function (or malfunction). However in each individual project there will be a clear path to a clinical use, diagnostic or therapeutic. Indeed in a number of the components of the program there are already potential treatments and diagnostics in development and trial.Read moreRead less
Molecular Determinants Of Risk, Progression And Treatment Response In Melanoma

Summary
Melanoma is a major Australian health problem. NSW figures for 2002 show it to be the second most common cancer in men and women. It has a disproportionately heavy impact on productive years of the life of young Australians because it is the commonest cancer in those aged 15-45 years. The investigators are all associated with the Sydney Melanoma Unit (SMU), the world�s largest clinical service dedicated to the treatment of melanoma, treating >1200 new melanoma patients annually.

It has a disproportionately heavy impact on productive years of the life of young Australians because it is the commonest cancer in those aged 15-45 years. The investigators are all associated with the Sydney Melanoma Unit (SMU), the world�s largest clinical service dedicated to the treatment of melanoma, treating >1200 new melanoma patients annually. We have also recruited large cohorts of individuals with high susceptibility to melanoma, both familial and population-based, throughout southeastern Australia. We aim to utilise these unique, internationally-recognised resources to develop a scientific basis for 1) improved management of individuals at high risk for development and progression of melanoma, and 2) improved treatment of patients with early and disseminated melanoma. We will base this on consolidation of existing collaborative research into molecular predictors of risk, progression and treatment response in melanoma.Read moreRead less
The Chief Investigators have worked as a team for 20 years as part of a successful NHMRC Program Grant that was renewed on three successive occasions and subsequently under a NHMRC Block Grant to QIMR. Their combined expertise covers the whole spectrum from the bedside to the bench with respect to clinical studies and fundamental molecular studies of iron homeostasis. The common theme of iron homeostasis and iron overload pervades virtually all the research of the team.

Their combined expertise covers the whole spectrum from the bedside to the bench with respect to clinical studies and fundamental molecular studies of iron homeostasis. The common theme of iron homeostasis and iron overload pervades virtually all the research of the team. The team�s research has led to fundamental observations of iron regulation and homeostasis and the development of guidelines for the management of, and screening for, haemochromatosis, recognized as the most common inherited disorder of Caucasian populations. The proposed research encompasses molecular studies aimed at deciphering the mechanisms of iron absorption and transport; how these processes are regulated; and clinical studies on patients diagnosed with haemochromatosis. The findings are particularly pertinent to the diagnosis, management and prevention of clinical haemochromatosis.Read moreRead less
Genetic And Bioinformatic Analysis Of Complex Human Diseases

Summary
Some human diseases are common in families; examples include prostate cancer, blood cancers, epilepsy and diabetes. Therefore, close relatives of individuals with a disease have an increased risk of being affected by this disease, implying a genetic basis. Finding the cause of these diseases is difficult, we will be developing novel approaches to the identification of genes responsible for these diseases. This is the first step towards the development of treatments for affected individuals.

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. To eliminate cells that are no longer needed or have become damaged, the body has developed a remark ....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. 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
