Funding Amount
$860,251.00
Summary
There is good evidence that the brain can control blood glucose, but we do not know how this occurs, or why this doesn’t work in diabetes. This grant will use cutting edge mouse genetic technology to determine how the brain controls blood glucose, and what changes in diabetes. This grant will determine how several hormones act through the brain to change glucose levels, and will help develop new strategies to treat high blood glucose.
Glutathione Transferase Zeta: A Novel Regulator Of Glucose And Lipid Metabolism

Funding Amount
$604,143.00
Summary
Obesity is a problem of global significance as a cause of preventable illness and death. The many consequences of obesity including cardiovascular disease, type 2 diabetes, cancer and osteoarthritis are an increasing burden on affected subjects and on the health care system. Our recent studies have revealed a novel pathway for the regulation of obesity. This discovery has provided a new target for the development of drugs for obesity and related disorders.
Role Of Microvascular Flowmotion In Skeletal Muscle Glucose Metabolism

Funding Amount
$596,971.00
Summary
Obesity and type 2 diabetes are nationally and globally reaching epidemic rates. This project investigates the regulation of blood flow within muscle and its impact on metabolism. Outcomes from the study may lead to diagnostic tools and treatments for cardiovascular disease associated with obesity, hypertension and type 2 diabetes.
Carnitine Acetyltransferase (CrAT) Regulates Appetite And Body Weight Through The Melanocortin System

Funding Amount
$547,087.00
Summary
Carnitine metabolism in peripheral tissues, such as muscle, maintains appropriate cellular metabolism and function. Little is known about carnitine metabolism in specific populations of brain cells regulate food intake and appetite. This project aims to understand how carnitine metabolism affect brain cells that regulate food intake and body weight.
Post-stroke Hyperglycaemia – Treatment With Exenatide In Acute Ischaemic Stroke (TEXAIS) Trial

Funding Amount
$1,266,149.00
Summary
Raised blood glucose levels (hyperglycaemia) after a stroke is common. It reduces the efficacy of stroke treatments and results in worse outcomes. Insulin is not useful as a treatment for this as it causes frequent hypoglycaemia and does not improve clinical outcomes. Exenatide is a common diabetes drug that is simple to use and lowers blood glucose without hypoglycaemia. It will be tested in the Treatment with Exenatide in Acute Ischaemic Stroke (TEXAIS) trial.
Does Periodic Fasting Improve Insulin Sensitivity And Metabolic Health In Humans?
Funder

Funding Amount
$846,891.00
Summary
A large body of evidence for the health benefits and life-extending properties of dietary restriction exists. Recent findings suggest that periods of fasting can have beneficial effects, even without an overall reduction in caloric intake. This proposal will compare periodic fasting with and without weight loss, versus daily caloric restriction on metabolic health outcomes in humans and examine mechanisms that may contribute to this effects.
Carnitine Palmitoyl Transferase 1 In POMC Neurons Controls Glucose Homeostasis And Body Weight
Funder
National Health and Medical Research Council
Funding Amount
$474,499.00
Summary
The brain plays a critical role in body weight gain by balancing appetite-inducing and appetite-suppressing signals. An imbalance in this process causes obesity, promotes diabetes and cardiovascular disease. The aim of this research is to identify how appetite-suppressing brain signals are maintained as a method to prevent obesity progression.
Effect Of Bisphosphonates On Bone Architecture And Glucose Metabolism In Men With Prostate Cancer Receiving Androgen Deprivation Therapy: A Randomised Controlled Trial
Funder

Funding Amount
$566,215.00
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.
Radiosensitisation Of Diffuse Intrinsic Pontine Gliomas By Modulating Glucose Metabolism
Funder

Funding Amount
$325,000.00
Summary
Diffuse intrinsic pontine glioma (DIPG) represents the most aggressive cancer of childhood with no effective treatment available and radiotherapy is the only form of treatment that offers a transient benefit. We have successfully grown the first DIPG cells in the laboratory and found a new approach to radiosensitise them by targeting glucose metabolism. We will build on these findings and develop this treatment strategy to make this novel therapy available to children with this deadly disease.
Altering Meal Times To Reverse The Metabolic Consequences Of Shift Work
Funder

Funding Amount
$735,715.00
Summary
Shift work disrupts the internal body clock, which increases the risk for obesity and type 2 diabetes. Our research demonstrates meal timing plays an important role in this metabolic disturbance. Data from animal studies suggests that the adverse consequences of shift work can be reduced by eating only during the day. This study will investigate if this also occurs in humans, potentially leading to a straightforward solution to reduce the burden of chronic diseases in shift workers.
