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.

Role Of Microvascular Flowmotion In Skeletal Muscle Glucose Metabolism
Funder

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.
Many heart diseases are associated with impairment of energetics of the heart. Improving the heart's energetics can lead to improved survival and long-term outcomes. Perhexiline is a heart medication that works by improving the way the heart uses energy. Although effective, it is associated with long-term toxicities. Better understanding of this medication may lead to less adverse effects and also provide a basis for further investigation of drug development in the future.
The Critical Roles Of Heme Oxygenase-1 In The Response To Ischemia
Funder
National Health and Medical Research Council
Funding Amount
$690,593.00
Summary
Heme oxygenase-1 is a protein that recycles our body's iron which itself is essential for life because it is needed for the sensing, transport and use of oxygen we breath. The current project investigates a novel interplay between heme oxygenase-1 and our body’s major response to tissue oxygen becoming limited. By doing so, our project may provide the basis for novel treatments of conditions where arteries are obstructed, such as those that lead to heart attack and amputation.
The L-type Calcium Channel As A Reporter Of Successful Morpholino Oligomer Therapy In Treatment Of Duchenne Muscular Dystrophy Cardiomyopathy

Summary
Duchenne Muscular Dystrophy is a fatal muscle wasting disorder. We have previously characterised how the heart fails in a mouse model of muscular dystrophy. We now have preliminary data demonstrating that treatment of mice with morpholino oligomers can rescue cardiac function. This project will fully characterise the effect of the treatment on heart function and optimise therapy regimes with the view to utilising the optimised protocol as a guideline in treating cardiomyopathy in Duchenne Muscul ....Duchenne Muscular Dystrophy is a fatal muscle wasting disorder.

ABCA12 – A New Regulator Of Cellular Lipid Metabolism And Inflammation
Funder
National Health and Medical Research Council
Funding Amount
$786,676.00
Summary
Dysregulation of cholesterol metabolism plays a key role in a number of diseases – from diabetes and atherosclerosis to neurological and skin disorders. Mechanisms of regulation of cholesterol metabolism are poorly understood. We have recently discovered a new pathway regulating cholesterol metabolism and in this study we will investigate molecular, cellular and physiological mechanisms of this pathway and will identify the possibilities to target it for therapeutic intervention.
Oxidative Processes In Vascular Health And Disease
Funder

Funding Amount
$851,980.00
Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Atherosclerosis - The Key Roles Of HDL, Cell Cholesterol Metabolism And Vascular Function
Funder
National Health and Medical Research Council
Funding Amount
$7,085,050.00
Summary
Atherosclerosis, an accumulation of cholesterol in the artery wall, is a major cause of illness and premature death worldwide. It is caused by conditions such as low levels of the protective high density lipoproteins (HDLs), diabetes, smoking and abnormal function of arteries, all of which are linked to disorders of cholesterol metabolism. With our expertise in HDLs, cholesterol metabolism and artery function, our research will lead to the development of novel strategies for early detection and ....Atherosclerosis, an accumulation of cholesterol in the artery wall, is a major cause of illness and premature death worldwide.

Molecular Mechanisms Of Inherited Hypocholesterolaemias: Impact Of APOB And MTTP Mutations On Lipoprotein Assembly And Secretion
Funder
National Health and Medical Research Council
Funding Amount
$200,213.00
Summary
Inherited low cholesterol levels can be caused by mutations in either of two genes: APOB and MTTP. These genes encode proteins that are critical for the assembly of fat particles in the body. We plan to use cell lines to study how single amino acid changes out of the 4500 in ApoB and the 900 in the MTTP protein affect protein production, binding with other proteins, and fat particle assembly.
