The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

An Integrated Approach To Identify The Molecular Mechanisms Contributing To The Pathogenesis Of Insulin Resistance: Targeting The Liver And Skeletal Muscle
Funder
National Health and Medical Research Council
Funding Amount
$415,218.00
Summary
The inability of muscle and liver to utilise sugar from the blood is a major problem that contributes to the development of obesity and diabetes. How these problems occur is unknown. The goal of my research is to identify what causes the muscle and liver problem, and whether fixing these problems will reduce obesity and diabetes. Since the number of people with obesity and diabetes is predicted to double over the next decade, we need to understand the cause of these diseases.
Impact Of Advanced Glycation On Anti-atherogenic Properties Of High Density Lipoprotein
Funder

Funding Amount
$372,471.00
Summary
Type 2 diabetes is a rapidly growing medical problem in Australia and around the world. Diabetes affects human health through its complications and the cardiovascular complications are a cause for major concern. One of the complications is the effect on plasma lipids: it makes cholesterol carrying particles to accumulate in the blood vessels, causing atherosclerosis. We intend to investigate how diabetes modify these particles making them atherogenic.
Post-stroke Hyperglycaemia – Treatment With Exenatide In Acute Ischaemic Stroke (TEXAIS) Trial
Funder
National Health and Medical Research Council
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.
Biology Of EGFR Mutations In Glioblastoma Multiforme
Funder
National Health and Medical Research Council
Funding Amount
$287,445.00
Summary
The epidermal growth factor receptor (EGFR) is a protein that has a critical role in the development of normal cells. In glioma, the most lethal of the brain cancers, the EGFR is altered. These alterations result in uncontrolled activation of the EGFR, causing signals that promote the growth and survival of brain cancer. This grant seeks to understand the nature of the signals mediated by the altered EGFR, in turn helping us develop better therapeutics for the treatment of this deadly cancer.
A Simple Method To Improve Stem Cell Transplant Therapy
Funder
National Health and Medical Research Council
Funding Amount
$831,652.00
Summary
Despite the success of hematopoietic stem cell transplantation and years of promise, almost all other stem cell therapies are considered experimental and remain in preclinical or early-phase clinical testing. This study aims to improve the efficiency of stem cell transplantation by manipulating cellular metabolism prior to transplantation, if effective these results may offer hope to patients suffering from a broad range of disorders.
The Role Of The AMPK-ACC2 Signaling Axis In Metabolic Control During Exercise And Obesity
Funder
National Health and Medical Research Council
Funding Amount
$540,973.00
Summary
Australian society is experiencing an epidemic of obesity that is contributing to diabetes, cardiovascular disease and premature death. This project is investigating how exercise might prevent obesity and type 2 diabetes by examining the major pathways that regulate fat metabolism.
Understanding The Acute And Cumulative Metabolic Effects Of Prolonged Sitting In Adults
Funder
National Health and Medical Research Council
Funding Amount
$416,597.00
Summary
Sedentary behaviour (sitting time) has been linked to an increased risk of chronic illnesses, including type 2 diabetes and obesity, but recent evidence suggests that light-intensity activity (non-exercise activities of daily living) is associated with reduced risk. These studies will examine whether breaking up sitting time with frequent short periods of activity can overcome the negative effects of prolonged sitting on blood glucose and blood fats in overweight older adults.
Understanding The Metabolic Consequences Of Impaired AMPKa2 And NNOS� In Skeletal Muscle: Implications For The Metabolic Syndrome
Funder
National Health and Medical Research Council
Funding Amount
$575,527.00
Summary
The inability of muscle to utilise sugar from the blood is a major problem that contributes to obesity and Type 2 diabetes. Since the number of people with these diseases will at least double by 2030, we need to find out what causes this problem. We will examine whether two muscle proteins that are impaired in obesity and Type 2 diabetes are also responsible for impaired sugar utilisation. We think that increasing these muscle proteins will fix the _sugar problem�, and remedy these diseases.
Effects Of Replacement And Withdrawal Of Testosterone In Human Males On Muscle, Bone And Fat
Funder
National Health and Medical Research Council
Funding Amount
$156,682.00
Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases well being and contributes to muscle weakness, bone fragility and weight gain. Cutting edge technology will be used to help explain how AD may relate to these negative effects, particularly on muscle function. Given the importance of aging, frailty, osteoporosis and obesity, understanding the role of hormones in these conditions may have major implications for prevention and treatment.
