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.
Targeting Insulin Hypersecretion To Prevent Type 1 And Type 2 Diabetes

Summary
Diabetes develops when islet beta-cells fail to secrete insulin. While major differences exist in the mechanisms by which type 1 and type 2 diabetes develop, there is overlap in beta-cell susceptibility factors. We will investigate whether an islet 'overwork' response to excess nutrient loads underlies beta-cell susceptibility to failure in both types of diabetes. We will also develop novel pharmacological approaches to reduce islet 'overwork' to prevent and treat type 1 and 2 diabetes.
The Ghrelin Axis As A Target For Prostate Cancer Therapy

Summary
Prostate cancer affects one in nine Australian men in their lifetime, and although there have been great advances in treatments, advanced prostate cancer remains incurable. Current treatments often lead to side effects which affect quality of life. We have found that the appetite hormone, ghrelin, stimulates prostate cancer cell growth and may be a useful target for prostate cancer therapy. We predict that targeting the ghrelin axis will prevent some of the side effects of other treatments that ....Prostate cancer affects one in nine Australian men in their lifetime, and although there have been great advances in treatments, advanced prostate cancer remains incurable. Current treatments often lead to side effects which affect quality of life. We have found that the appetite hormone, ghrelin, stimulates prostate cancer cell growth and may be a useful target for prostate cancer therapy. We predict that targeting the ghrelin axis will prevent some of the side effects of other treatments that reduce quality of life for patients.Read moreRead less
Intervention To Reduce The Risk Of Diabetic Retinopathy And Early Adverse Retinal Changes In Type 1 Diabetes

Summary
The long term effects of young onset T1D may be devastating: diabetes is the leading cause of visual loss in young adults in Australia and other countries. We have the unique opportunity to investigate whether ACEI and statins will modify retinopathy through our collaboration with an already funded international multicentre trial. This study will treat adolescents for 4 years and will follow them for the next 5-10 years. We will use novel measures of retinal blood vessels size and fractals.
The Role Of Dicarbonyl-derived AGEs And RAGE In Diabetes Associated Atherosclerosis

Summary
Based on our pilot data we postulate that glucose derived molecules such as methylglyoxal (MGO) have effects on inflammation and oxidative stress leading to accelerated atherosclerosis in diabetes. Our studies aim to identify novel treatments which block these effects thus leading to superior protection and prevention of atherosclerosis in diabetes.
A Comprehensive Assessment Of Diabetes In The Urban Community Of Fremantle

Summary
In the Fremantle Diabetes Study Phase I, detailed data were obtained from a community-based patient cohort between 1993 and 2001. There is strong evidence that diabetes in Australia is changing rapidly. To provide up to date data to health care providers and government, to confirm observations made in Phase I and to venture into new areas, Phase II began in 2008. We plan to extend Phase II for a further 5 years by following all 1,732 patients to achieve at least 6 years of comprehensive assessme ....In the Fremantle Diabetes Study Phase I, detailed data were obtained from a community-based patient cohort between 1993 and 2001.

Effect Of Bisphosphonates On Bone Architecture And Glucose Metabolism In Men With Prostate Cancer Receiving Androgen Deprivation Therapy: A Randomised Controlled Trial

Funding Amount

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.
Epigenetic Determinants Of Nephropathy In Adults With Type 1 Diabetes

Summary
The prevention and successful management of diabetic complications are issues of utmost importance for the health of Australians. We hypothesize that epigenetic pathways partly determine why some individuals with diabetes develop complications of their disease, while others do not, despite a similar duration of diabetes, treatment intensity and mean glucose exposure.
Is CYP11A1 Critical For The Vitamin D Photoprotective System In Skin?

Funding Amount

Summary
Sunlight produces DNA damage. When inadequately repaired, this damage produces skin cancer. The vitamin D system in skin helps protect against this skin damage, but the vitamin D compounds involved and how they work is unclear. Recent data shows new vitamin D compounds with photoprotective activity and that vitamin D compounds increased expression of DNA repair proteins. These studies may enable pharmacological enhancement of protection from sunlight.
Control Of Musculoskeletal Function And Body Composition By Androgens In Men

Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases general well being and contributes to muscle weakness, bone fragility and weight gain. By using cutting edge imaging and molecular technologies, we will help to explain the underlying mechanisms of how AD leads to these negative effects. This should ultimately lead to reduction of adverse outcomes of AD, which include fractures and cardiovascular events.
