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.

The Role Of The MicroRNA Let 7 In Diabetic Proliferative Vascular Disease

Summary
Cardiovascular complications remain the major cause of mortality in diabetes and our current treatment strategies are insufficient to reduce this burden. We have obtained extensive data to show that a novel molecule (the micro RNA, let 7b) has antiproliferative and vasculoprotective effects in diabetes. Thus, we propose that modulation of micro RNA let 7b specifically in vascular smooth muscle cells within the vascular wall represents a promising target to combat cardiovascular disease, in parti ....Cardiovascular complications remain the major cause of mortality in diabetes and our current treatment strategies are insufficient to reduce this burden.

Effects Of Replacement And Withdrawal Of Testosterone In Human Males On Muscle, Bone And Fat

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.
The Role Of Grb10 In The Regulation Of Muscle Metabolism

Funding Amount
$624,960.00
Summary
Obesity increases the risk of metabolic diseases such as type 2 diabetes. Muscle is a key tissue for balancing whether energy is used or stored as fat and as we age, muscle mass normally decreases making maintaining a healthy metabolism even more difficult. We have discovered that removing the Grb10 gene from mice produces bigger muscles. This project will investigate the mechanisms of this effect so that strategies can be developed to regulate muscle mass and improve metabolic health
The Role Of Dicarbonyl-derived AGEs And RAGE In Diabetes Associated Atherosclerosis
Funder
National Health and Medical Research Council
Funding Amount
$470,617.00
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.
Biomarkers For Risk And Outcomes Of Type 2 Diabetes: A Discovery And Validation Approach In Australian And Chinese Subjects
Funder
National Health and Medical Research Council
Funding Amount
$599,489.00
Summary
The aim is to make better outcomes for people with Type 2 diabetes in Australia and China, by exploring various tests to improve prediction of diabetes progression, complication risk and treatment response. The team has data and samples from the Fenofibrate Intervention and Event Lowering in Diabetes Trial and from the Shanghai Diabetes Study. This approach is very time and cost-effective. We will also study animal models to understand mechanisms of diabetes damage, and test new treatments.
Effect Of Testosterone Treatment Combined With Dietary Restriction On Body Fat Mass And Muscle Function In Obese Men: A Randomized Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$140,949.00
Summary
Obesity, an increasing health and economic burden, is associated with lowered testosterone levels in men. While both dietary restriction and testosterone treatment reduce body fat, whether a combination of these two approaches achieves a more pronounced fat mass reduction is unknown. We will conduct a rigorous 12 month clinical trial of testosterone treatment in 150 obese men with a low testosterone level. All men will receive dietary intervention to induce and maintain weight loss
