Summary
For patients with Type 1 Diabetes, improved glucose control has been shown to reduce the development of diabetes complications. Although advances have been made in therapy, most people with diabetes do not achieve optimal treatment targets and the burden of care is high. Technologies now exist that allow the development of automatic insulin therapy and the artificial pancreas. These experiments will test a novel portable system that represents a significant step advancing toward this goal.
Type 2 diabetes is a health crisis in Australia. In this project, we will investigate the mechanisms whereby high glucose and fat impair pancreatic beta-cell function leading to type 2 diabetes. We will establish how endoplasmic reticulum stress and the protein Id1 are linked with loss of beta-cell gene expression and function. The information gained will further our understanding of the basic mechanisms regulating insulin secretion and provide new therapeutic targets for diabetes treatment.
Effect Of Bisphosphonates On Bone Architecture And Glucose Metabolism In Men With Prostate Cancer Receiving Androgen Deprivation Therapy: A Randomised Controlled Trial

Summary
Androgen deprivation therapy (ADT) is a type of hormonal treatment which is effective for prostate cancer treatment. However, ADT may cause bone fragility, weight gain, diabetes and heart disease. We will examine the effects of a bone strengthening treatment on bone structure and glucose metabolism in men receiving ADT. This trial should help in better define the risk benefit ratio of ADT, and therefore provide treating doctors with better guidance as to when and how to use this therapy.

Summary
Type 2 diabetes is caused by insulin resistance, a condition that is characterised by the inability of insulin to elicit its normal function to lower blood sugar levels. The cause of insulin resistance is not known. In this study we will determine the role of a novel gene called UBL-5 to elicit insulin resistance in muscle and fat by generating genetically-induced models in which this gene has been deleted.

Summary
In obese humans, storing excess fat within the abdomen is associated with the development of adult-onset diabetes and cardiovascular disease. However, the mechanisms linking intra-abdominal fat accumulation with these diseases are not well understood. We have studied intra-abdominal fat accumulation in mice using a transplant model, and we have found that transplanting subcutaneous fat intra-abdominally prevents diet-induced obesity and glucose intolerance.

The Treatment Of BOoking Gestational Diabetes Mellitus Study: The TOBOGM Study

Summary
Gestational diabetes mellitus (GDM) related pregnancy complications are reduced with treatment from 24-28 weeks pregnant. Many women are diagnosed/treated earlier without evidence of benefit and possible risk of harm. In TOBOGM women under 20 weeks pregnant with mildly raised blood glucose will be allocated by chance to either immediate treatment, or awaiting a repeat diabetes test at 24-28 weeks pregnant to decide treatment. Harmful and beneficial effects on mother and baby will be compared.
The proposal focuses on a novel angle explaining how pancreatic beta cells normally match their insulin synthesis, storage and secretion in response to an enhanced demand as occurs during obesity, and how this fails in the progression to Type 2 diabetes. In particular we will expand our discovery that glucose rapidly enhances the synthesis of a novel factor regulating gene transcription. This will generate basic knowledge that will potentially help design of novel therapies for Type 2 diabetes.
A Novel Role For Alzheimer Tau Protein In Insulin Secretion And Type 2 Diabetes

Summary
There is a strong association between type 2 diabetes and Alzheimer's disease, however the reason for this is not known. In Azheimer's disease a protein called tau does not function normally and contributes to the declining cognitive function. We have shown that when tau is absent, this lowers blood glucose and reduces the hallmark defects that contribute to type 2 diabetes. By understanding how tau works we may be able to provide better therapeutic agents to treat type 2 diabetes.
ADVANCE-ON: A Post-trial Observational Study Of ADVANCE

Summary
The ADVANCE (Action in Diabetes and Vascular Disease) study demonstrasted that intensive control of blood glucose only reduced kidney disease but that control of blood pressure reduced both cardiovascular and kidney disease. This 10-year post-trial follow up study will determine whether intensive control of blood glucose exerts cardiovascular benefits that emerge in the long term in patients with type 2 diabetes.
Cystic Fibrosis - Insulin Deficiency, Early Action (CF-IDEA)

Summary
Cystic Fibrosis (CF) is the most common life-threatening genetic condition affecting Australian children. As well as repeated lung infections, children with CF develop insulin deficiency and eventually diabetes. The CF-IDEA trial (Cystic Fibrosis – Insulin Deficiency, Early Action) will determine whether starting insulin treatment before the onset of diabetes (earlier than current practice) will improve the health of children with CF by improving body weight and lung function.
