Summary
Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. ....Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. Osteoporosis results from an excess of bone breakdown over formation, and our Program aims to identify the factors that regulate these processes, and develop new therapies that can modify them. We will also determine what it is about bone cell properties that make some cancers, especially those of breast and prostate, particularly prone to spread to bone.Read moreRead less
Type 2 diabetes (T2D) is threatening the health of this nation and if unchecked will cripple our health care system. There are several problems: (1) The incidence of T2D is growing and we do not fully know why; (2) T2D involves defective insulin action but how insulin works normally is still unclear; (3) much research in this area is performed in laboratory cells or animals and the translation of this research to the human disease is yet to be fully realised; and (4) current therapies and diagno ....Type 2 diabetes (T2D) is threatening the health of this nation and if unchecked will cripple our health care system. There are several problems: (1) The incidence of T2D is growing and we do not fully know why; (2) T2D involves defective insulin action but how insulin works normally is still unclear; (3) much research in this area is performed in laboratory cells or animals and the translation of this research to the human disease is yet to be fully realised; and (4) current therapies and diagnostic markers for early disease prediction are inadequate. Our goal is to make progress in each of these areas.Read moreRead less

Summary
The team comprises internationally recognised experts in basic, clinical and public health applied research in cardiovascular disease, particularly atherosclerosis that is the commonest cause of death in Australia and other developed countries. Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol. The significance of the proposed studies is that, on the one hand, they will provide new infor ....The team comprises internationally recognised experts in basic, clinical and public health applied research in cardiovascular disease, particularly atherosclerosis that is the commonest cause of death in Australia and other developed countries. Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol. The significance of the proposed studies is that, on the one hand, they will provide new information on how 'good' lipoproteins protect us from atherosclerosis. This information can then be used to regulate 'good' cholesterol in a meaningful manner. On the other hand, the proposed studies will provide fundamental insights into how a range of lifestyle factors, physiological processes and pathological conditions relate to both the function of blood vessel-lining cells and susceptibility of individuals to atherosclerosis.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
