Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less

Summary
Liver disease, a significant burden on society, affects many in the prime of their life. Scarring of the liver is a response to injury due to many factors including alcohol, viruses, obesity, and fatty-liver disease. We have identified a protein associated with liver injury. In this project we will perform a systematic analysis to understand the role of this protein in injury progression. Ultimately we intend to develop tools to prevent and treat liver injury.
Molecular Regulation Of Metabolism And Body Composition By Ski Via Crosstalk With Nuclear Hormone Receptor Signalling.

Summary
Obesity is a common and burdensome health problem in the community which leads to diabetes and heart disease. A number of factors, including hormones play important roles in determing risk of obesity. This study proposes to investigate whether the Ski gene which is a regulatory factor for many hormones affects metabolism in transgenic mouse models of altered Ski function. The proposed studies may identify Ski as a target for therapy for obesity and improvement in sketal muscle metabolism.

Summary
The diabetes epidemic is a growing challenge for the Australian health care system with over 1 million Australians living with diabetes. The impact on individuals' lives and the whole of Australian society is very substantial indeed. There is very good evidence that this impact would be reduced by developing new approaches to manage the disease and facilitate improved self-management.

The impact on individuals' lives and the whole of Australian society is very substantial indeed. There is very good evidence that this impact would be reduced by developing new approaches to manage the disease and facilitate improved self-management. Recent developments in information and communications technologies offer some promising new ways and tools for achieving this. This research will evaluate a computer-controlled, interactive telephone system for improving the management and self-management of Type 2 diabetes in addition to routine care. Patients with Type 2 diabetes will be recruited from Brisbane and each patient will be randomly assigned to receive either this new program or just their usual care from their doctor or Diabetes Clinic. The first group will call the system weekly for six months using a regular phone or a mobile phone if they wish. During the call, they will answer questions by speaking into the phone, listen to feedback and strategies for improving management of their diabetes and then discuss their next targets and behavioural actions. They will receive systematic and tailored advice on blood glucose testing, nutrition and physical activity, as well as medication taking and foot care. The system individualises conversations according to the user s answers and responses over all the interactive sessions. The trial will formally evaluate the clinical impact on blood glucose control and the adoption and maintenance of the targeted health habits, as well as the intervention s cost-effectiveness and users satisfaction with the system. This project s significance lies in the excellent potential of using this new technology to provide a 'low cost' but effective program to help people better manage Type 2 diabetes.Read moreRead less
EPIGENETIC REPROGRAMMING OF MALIGNANT BREAST CANCER

Summary
Poorly differentiated breast cancers are aggressive tumors, frequently resistant to chemotherapy and associated with high morbidity. Herein we propose the engineering of more selective therapeutic agents able to target the genes involved in cancer initiation and resistance to treatment. We aim to correct and reprogram the cancer cell genome in state that is similar to normal, not tumorigenic cells. This work will generate novel forms of treatment for cancers that are presently not curable.
TELEPHONE COUNSELLING FOR MAINTENANCE OF PHYSICAL ACTIVITY, WEIGHT LOSS And GLYCAEMIC CONTROL IN TYPE 2 DIABETES

Summary
Regular exercise, a healthy diet and weight loss are key to managing type 2 diabetes, yet these are major challenges for most people with diabetes. This study will evaluate the impact of a telephone counselling program to assist people with type 2 diabetes to exercise, eat a healthy diet and lose weight, with the goal of helping them to sustain these changes over the long-term. It is expected that these lifestyle changes will also result in improved blood glucose control and quality of life.
Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle ....Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle and adipose tissue by stimulating the movement of a glucose transport protein from inside the cell to the cell surface (see http:--www.imb.uq.edu.au-groups-james-glut4 for an animated description of this process). The purpose of this proposal is to dissect the molecular mechanisms by which this glucose transporter can be held inside the cell in the absence of insulin and then allowed to be released from this site moving to the surface in the presence of insulin. Our studies over the past 5 years have brought us much closer to understanding this process in detail. The identification of the molecules responsible for this regulatory step will not only aid our understanding of this process but it will also provide a valuable target for development of therapeutic agents that can be used to combat insulin resistance.Read moreRead less

Australia is well positioned to capture the market for this rapidly growing species. We propose to enhance the already favourable growth rates of Haliotis asinina in aquaculture by delineating critical environmental and genetic factors that effect production. This proposal uniquely melds commercial production practices at MG Kailis Export Pty Ltd with expertise in aquaculture and marine biotechnology present at The University of Queensland and CSIRO Marine Research. This knowledge will enhance the development of this new aquaculture industry in tropical Australia.Read moreRead less
