Summary
The EU-COGS application has arisen from genome wide scans that identify common genetic variants associated with breast, ovarian and prostate cancer risk. Our studies contributed 50% of DNA samples to the prostate cancer genome wide scan. COGS will now measure these variants in a large number of cases and controls from an international consortium of studies to test whether genetic risks are modified by other genes or lifestyle factors.

Our studies contributed 50% of DNA samples to the prostate cancer genome wide scan. COGS will now measure these variants in a large number of cases and controls from an international consortium of studies to test whether genetic risks are modified by other genes or lifestyle factors. This will better define genetic risks and identify men at increased risk who should be the focus of appropriate screening and prevention strategies. Australian participation in the prostate cancer genome wide scan helped to identify a number of genetic variants associated with prostate cancer risk. The aim of EU-COGS, which needs large numbers of samples with epidemiological, tumour pathology and clinical information, is to determine whether these genetic variants act singly or together and the extent to which lifestyle and environmental factors can modify the genetic risk. Our contribution of >10% of the total DNA samples to COGS will enable us to understand how such genetic risks can be modified in the Australian environmental context.Read moreRead less
Measuring Changes In Fluids, Fat, Muscle Mass, Proteins & Other Body Components Non-invasively Through Course Of Illness

Summary
The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with no ....The course of non-cancer related disease is difficult to assess clinically making it hard for clinicians to accurately predict the end of life course of illness for patients. No matter what the end of life disease is, death will involve multi-system organ failure and changes in body composition. These changes, including fluid distribution, muscle mass and type and fat mass as well as measures of body mass index, basal metabolic rate and arm muscle circumference can be accurately followed with non-invasive multi-frequency bio-impedance. This information will provide a basis to either confirm the clinical diagnosis or lead to recommendations for change.Read moreRead less

Summary
An individual relies upon their immune system to protect against invasion by hostile organisms. The system usually works well. Invading agents (the 'non-self') are detected and attacked by the immune system's patrolling killer T cells. These normally beneficial cells are called T cells because they were formed and educated in an organ called the thymus, which kick-starts our immune system in childhood, but falls into inactivity by adolescence. Sometimes the education system in the thymus goes wr ....An individual relies upon their immune system to protect against invasion by hostile organisms. The system usually works well. Invading agents (the 'non-self') are detected and attacked by the immune system's patrolling killer T cells. These normally beneficial cells are called T cells because they were formed and educated in an organ called the thymus, which kick-starts our immune system in childhood, but falls into inactivity by adolescence. Sometimes the education system in the thymus goes wrong and it releases T cells that mistakenly attack 'self' instead of 'non-self'. This causes autoimmune diseases, such as type1 diabetes, multiple sclerosis and rheumatoid arthritis. The Euro-Thymaide project aims to determine why and how self-attacking T cells are mistakenly released from the thymus into the body. Usually such errant T cells are detected and destroyed within the thymus, before they have the opportunity to escape and cause autoimmune diseases. The ultimate objective is to learn about the thymus recognition process and help the immune system detect and destroy faulty T cells that patrol the body, thereby preventing the onset of autoimmune diseases.Read moreRead less

Summary
This research program will examine the cellular and molecular mechanisms underlying the loss of Beta cell mass and function: During the pathogenesis of Type 1 Diabetes Mellitus (T1D); and Following islet transplantation. Though these processes have traditionally been considered to be purely immune-mediated, it is now clear that the response of the beta cell is critical to the final outcome of the auto-immune process and response to therapeutic interventions.

Though these processes have traditionally been considered to be purely immune-mediated, it is now clear that the response of the beta cell is critical to the final outcome of the auto-immune process and response to therapeutic interventions. Thus the complex interactions between the cellular and soluble constituents of the immune system, plus the effects of a deregulated metabolic milieu, are integrated at the beta cell. This in turn activates a series of complex transcriptional programs in the beta cell that together determine the beta cells ultimate functional status and survival. We will use knowledge gained from studying these processes to drive the development of novel therapeutic targets and strategies to improve the success of immune-based and transplantation-based therapies.Read moreRead less

Role Of Heparan Sulfate, Heparanase Inhibitors In The Development And Prevention Of Type 1 Diabetes
Funder

Funding Amount
$3,242,772.00
Summary
Our recent studies have shown that a special protein (an enzyme called heparanase) and the special carbohydrate (heparan sulfate or HS) that it degrades, play a previously unrecognised role in the development of Type I diabetes (T1D) in mice. We will explore whether destructive immune cells use heparanase to damage insulin-producing islets and deplete them of HS, resulting in islet cell death and T1D. We will develop new agents to inhibit this damage, prevent T1D and protect islet transplants.
