Summary
Over the past decade work from our group has identified that a group of proteins, termed gp130 receptor cytokines, can lead to improvements in both causes and symptoms of type 2 diabetes in both animals and humans. Unfortunately, due to side effects, clinical trial using analogues of these proteins have failed. We believe we know why this is the case and we now have developed new, improved peptides that should overcome these side effects. We hope that we have created a novel drug that will help ....Over the past decade work from our group has identified that a group of proteins, termed gp130 receptor cytokines, can lead to improvements in both causes and symptoms of type 2 diabetes in both animals and humans.

The Role Of Vitamin D In Beta-cell Function And Diabetes

$554,248.00
Summary
Vitamin D deficiency is common in Australia, with the success of the 'slip, slop, slap' campaigns. Low levels of Vitamin D have been associated with diabetes. This grant aims to determine how vitamin D affects insulin release and blood glucose levels.
This research proposal will identify changes in liver-secreted proteins during the development of fatty liver, and in the transition from fatty liver to the more advanced form of liver disease, non-alcoholic steatohepatitis (NASH). Understanding the differences in protein secretion between NASH patients and patients with normal/fatty liver will provide the opportunity to identify disease biomarkers that could be determined from a blood sample. This will provide a major shift in clinical care.
Lipid Metabolism In The Hypothalamus: Implications For Obesity And Diabetes Development

Funding Amount
$592,915.00
Summary
Obesity is defined by excessive fat storage and defective lipid metabolism, not only in adipose tissue, but also in most tissues throughout the body. Obesity-induced changes in lipid metabolism extends to the brain and is associated with impaired cognitive function. This work aims to determine how obesity affects neurons in the key feeding centres of the brain, and whether excessive lipid storage in neurons induces changes in body weight regulation and metabolism.
Altered Protein Secretion Links The Fatty Liver To Metabolic Disease

Funding Amount
$415,797.00
Summary
The liver secretes proteins to alter metabolism in other tissues of the body. Fatty liver is a major feature of obesity and type 2 diabetes. This project aims to understand how fatty liver changes protein secretion and how this impacts on metabolic processes. The outcomes of this project will be the identification of protein biomarkers of fatty liver and the prediction of insulin resistance development in other tissues of the body.
Obesity is associated with type 2 diabetes, fatty liver disease, cardiovascular disease and cancer. These inter-related diseases reduce life expectancy and their treatments come at an enormous financial cost. The overriding aim of this work is to understand the molecular and cellular regulation of lipid metabolism in skeletal muscle, liver and adipose tissue, and how this impacts endocrine function to affect the pathogenesis of types 2 diabetes and prostate cancer.
Restoration Of Diabetes Associated Cognitive Deficits Through The Modulation Of Cerebrovascular Integrity

Funding Amount

Summary
Diabetes is known to increase the risk of dementia. Although the mechanisms are currently unknown, a recently emerging body of evidence suggest that damaged blood vessels of the brain may be central to onset and progress of cognitive dysfunction. Consistently, the dysfunction of brain blood vessels is often observed in the brain of diabetes subjects. Therefore, this project will investigate whether the amelioration of disrupted brain blood vessels restores the cognitive function in diabetes.
Dementia Associated To Diabetes: Prevention Through The Modulation Of Cerebrovascular Integrity

Funding Amount
$719,770.00
Summary
Diabetic insulin resistance is reported to induce cognitive decline and dementia. An accumulating body of evidence suggest that compromised integrity of neurovascular unit and following changes in cerebral lipid homeostasis may be centrally involved in the neurodegeneration and cognitive deficits. Therefore, the project aims to prevent the insulin resistance-associated cognitive impairment by modulating the integrity of cerebrovasculature and lipid homeostasis.
Curing Fatty Muscles: Understanding The Role Of PLIN5 In Lipid Metabolism And Tissue Function

Funding Amount
$462,162.00
Summary
Diseases associated with the deposition of lipids in muscle are becoming an increasingly important medical problem as the incidence of obesity increases. Skeletal muscle and cardiac function are greatly altered by excessive lipid deposition. The protein PLIN5 is important in regulating fat metabolism. This project aims to determine the functions of PLIN5, how PLIN5 is regulated and whether altering PLIN5 contributes to the development of diabetes and heart failure.
An Essential Role For Skeletal Muscle FoxO1 In Protecting Against Obesity-induced Insulin Resistance

Funding Amount
$593,888.00
Summary
Skeletal muscle is the largest organ in the human body and accounts for approximately 80% of glucose disposal after a meal. We have identified a transcription factor, namely FoxO1, that appears protect against obesity-induced insulin resistance by promoting energy consumption. This project will examine whether skeletal muscle specific activation of FoxO1 is a possible therapeutic target for the treatment of obesity-induced insulin resistance.
