Childhood diabetes [both type 1- and young type 2-] is increasing alarmingly. Diabetes prevention will be a great benefit via both a healthier population and relief to the national health budget. To develop targeted preventive treatments we first need to identify genetic risk factors, requiring access to a large number of samples. We will establish a national Repository which will make DNA available to all qualified Australian researchers enhancing their ability to identify causes of diabetes.
A Longitudinal Study Of Nerve Morphology In Diabetic Neuropathy Using Novel Non-invasive Ophthalmic Surrogate Markers

Summary
This research project will use two new ophthalmic instruments - the corneal confocal microscope and non-contact corneal aesthesiometer - to directly monitor changes in corneal nerves and corneal sensitivity, over a 5 year period, in diabetic patients suffering from a painful condition of the arms and legs known as diabetic neuropathy. This study will generate important new information that could allow diabetic doctors to more accurately monitor the progression of the disease.
The Role Of Hypoxia Inducible Factor 1a In Beta-Cell Function And Diabetes

Summary
HIF1a is a gene which our preliminary data shows is needed for normal beta-cell function and insulin secretion. When beta-cells cannot release enough insulin, blood sugar levels rise, and diabetes develops. This research plan will look at the effects of deletion of HIF1a and of increasing HIF1a to see how this affects function of beta-cells and - or diabetes development. This work may show that HIF1a is a potential therapeutic target for the treatment of diabetes in humans.
Defining Vascular Health And Modifiable Risk Factors Over Time In Childhood.

Summary
Adult heart disease and strokes have their origin in childhood. We will follow healthy children and children with diabetes or obesity over 2 years during puberty when blood vessel disease is detectable. We will define which are the most sensitive markers of blood vessel disease and the continuum of risk factors. This is essential knowledge to best define children at risk and to test clinical and public health interventions.
Apoptotic Pathways In Pancreatic Beta Cells Leading To Type 1 Diabetes And Transplant Rejection

Summary
The destruction of insulin-producing beta cells in the pancreas by immune cells leads to the need for daily insulin injections in patients with type 1 diabetes. This project aims to understand how beta cells are destroyed. A knowledge of the process by which this occurs will indicate ways we can protect these cells. Our previous work has suggested strategies that may protect beta cells, and we aim to test these. Such protection may eventually allow beta cell replacement by transplantation.
A Single Fibre Study Of The Relationship Between Glucose Transport And Skeletal Muscle Contractility

Summary
Type 2 diabetes (a progressive disorder often accompanied by obesity) is claimed to be the most common metabolic disease in the world and is predicted to affect 1.15 million Australians by the year 2010. Muscle contraction (in the form of physical exercise or exercise training) is now an essential component in the management of type 2 diabetes and-or obesity.This project has been planned from a perspective that combines theoretical and experimental expertise in the field of muscle cell contracti ....Type 2 diabetes (a progressive disorder often accompanied by obesity) is claimed to be the most common metabolic disease in the world and is predicted to affect 1.15 million Australians by the year 2010. Muscle contraction (in the form of physical exercise or exercise training) is now an essential component in the management of type 2 diabetes and-or obesity.This project has been planned from a perspective that combines theoretical and experimental expertise in the field of muscle cell contractility with a keen interest in the role of skeletal muscle in glucose homeostasis. Work carried out within the scope of this project will contribute new insights into the pathogenesis of type 2 diabetes-obesity and new information on the cellular mechanisms involved in contraction-stimulated glucose transport by skeletal muscle. As part of this project we will develop single muscle cell-fibre preparations and appropriate protocols for monitoring cellular aspects of glucose transport in skeletal muscle. These preparations-protocols will have the potential to be used for testing anti-diabetic drugs directed towards intracellular targets. From an educational benefit point of view, the project will create the opportunity for 4-6 honours and 2-3 PhD students to acquire a rare and useful combination of skills and expertise in muscle cell biochemistry and physiology, while working on an issue of medical concern.Read moreRead less
Viral Triggers Of Autoimmunity And Type 1 Diabetes: A Prospective Study Of At Risk Children

Funding Amount
$475,106.00
Summary
We are studying the role of viruses in causing type 1 (insulin dependent) diabetes. By following babies from birth, we can see whether early signs of damage to the body's insulin producing cells results from infection with particular viruses. We will study the genes and other features of these viruses to help us understand why they cause diabetes, and how they relate to other factors such as diet and vitamin D. The results may provide valuable information for the future prevention of diabetes.
