Heart disease remains the leading cause of death in our society. Almost two million Australians suffer from the debilitating effects of heart disease and it is the leading cause of premature permanent disability in our workers. Heart defects are also the most common type of birth defect and the leading cause of deaths in infants dying from birth defects. Many of these problems can be attributed directly to defects in the development, repair and-or function of heart muscle and, at the cellular le ....Heart disease remains the leading cause of death in our society. Almost two million Australians suffer from the debilitating effects of heart disease and it is the leading cause of premature permanent disability in our workers. Heart defects are also the most common type of birth defect and the leading cause of deaths in infants dying from birth defects. Many of these problems can be attributed directly to defects in the development, repair and-or function of heart muscle and, at the cellular level, of heart muscle cells or cardiomyocytes. Understanding the cardiomyocyte as well as integrated heart development, biology, physiology and function, therefore, holds great promise for major advances in the prevention and treatment of contemporary heart diseases. This Program Grant brings together a unique team of interactive researchers with expertise in cardiovascular physiology, as well as developmental, cellular and molecular biology. The outcomes anticipated from new insights into heart biology that will result from the proposed studies, are the development of novel therapeutic approaches for the prevention and treatment of heart attacks and heart failure.Read moreRead less

Summary
Diseases such as autoimmune gastritis, multiple sclerosis and diabetes arise because a rogue immune system has turned inwards to attack our organs. The organ destruction follows from recognition by the immune system of specific molecules in these organs. These autoimmune diseases are incurable and controlled mainly by long-term administration of substances that suppress the immune system, often with serious side-effects.

The organ destruction follows from recognition by the immune system of specific molecules in these organs. These autoimmune diseases are incurable and controlled mainly by long-term administration of substances that suppress the immune system, often with serious side-effects. A rational approach is to render the rogue immune system harmless by removing the cells that recognize these particular molecules. This can be achieved by a Trojan horse approach in which the molecules are delivered to the immune system such that that the immune cells that recognize them are removed. To deliver these molecules to the immune system we will genetically engineer bone marrow stem cells, or embryonic stem cells that generate these stem cells, because they are precursors of mature immune cells. Rejection of organ transplants arise in a similar way and also require long-term immunosuppression. A similar approach can therefore be taken to promote acceptance of foreign organ grafts. In the aged, we will combine these approaches with rejuvenation of the immune system by blockade of sex steroid production and-or by creation of a new immune organ.Read moreRead less
The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammator ....The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammatory or allergic disease, such as arthritis or asthma. This team of researchers from the Hanson Institute in Adelaide, combining expertise in molecular and cell biology, protein chemestry, structual biology and animal models, has been working together for over 10 years, investigating the molecular mechanisms involved in controlling the formation and activities of blood vessels and white blood cells. This program seeks to further that understanding, and to develop drugs that have the potential of ameliorating the inflammatory condition.Read moreRead less

Summary
Cancer of the colon and rectum is the most common form of cancer in Australia. Over 12,000 people are diagnosed each year with colorectal cancer (CRC) and more than one third of people will die of their disease. CRC is caused by mistakes in production of colon cells. Our research aims to discover new ways to detect CRC, develop smart drugs and nanoparticle delivery systems for destroying all types of CRC cells. We will then test our new anti-cancer drugs in clinical trials with CRC patients.

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

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
