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.

Phosphoinositide 3-kinase Signalling And Skeletal Muscle Mass.
Funder
National Health and Medical Research Council
Funding Amount
$597,598.00
Summary
Maintenance of skeletal muscle mass is essential for human health and locomotion. In ageing and cancer, loss of muscle mass leads to severe weakness and immobilization causing morbidity and mortality. This grant aims to characterise a novel gene that when deleted in mice leads to significant muscle damage. The molecular pathways within the cell that lead to the observed muscle damage will be investigated and this may provide insights into the pathways that control muscle damage and its regenerat ....Maintenance of skeletal muscle mass is essential for human health and locomotion.

Finding The Missing Katanin Required For Male Fertility
Funder
National Health and Medical Research Council
Funding Amount
$417,214.00
Summary
Microtubules are a key element of all cells, including in the male germ line. In this project we will define the function of the microtubule severing protein KATNA1 in male fertility. This will be achieved using a unique model and state-of-the-art technologies. This project will have immediate relevance to the 1 in 20 Australian men who suffer from infertility but will also inform KATNA1 function in the many other tissues where KATNA1 is produced.
Dissecting The Central Organisation Of Cough Neural Networks
Funder
National Health and Medical Research Council
Funding Amount
$880,928.00
Summary
Cough is the most prevalent symptom of lung disease and the most common reason for people to seek medical advice. However, cough neural processes are poorly defined and as a result current cough therapies are largely ineffective making cough a significant unmet clinical problem. This project will novel viral strategies to dissect and manipulate cough neural pathways in the brain, providing insights into the neural processing of airway sensations and coughing.
Low Dose Aspirin And Age-related Macular Degeneration: Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$1,043,189.00
Summary
Age-related macular degeneration (AMD) is a major cause of visual impairment in advanced countries, responsible for nearly half of all legal blindness in Australia. Due to increased life expectancy, the number of people with this progressive late onset disease will double by 2025. Aspirin could prevent or delay the onset of AMD in older persons but its bleeding risk also needs to be considered. This project will determine whether treatment with low dose aspirin reduces incidence or progression o ....Age-related macular degeneration (AMD) is a major cause of visual impairment in advanced countries, responsible for nearly half of all legal blindness in Australia.

Ontogeny Of The Airway Smooth Muscle Layer In Health And Disease
Funder
National Health and Medical Research Council
Funding Amount
$535,914.00
Summary
In asthmatic patients the thickness of the airway smooth muscle (ASM) layer is increased early in life and even before doctor-diagnosis. An intriguing possibility is our overarching hypothesis that the ASM layer is thickened from birth and represents an independent risk factor for the development of asthma. This project strives to understand better how the ASM layer matures from late gestation to adulthood and whether abnormal maturation contributes to disease susceptibility.
Hepatocellular Carcinoma: Understanding The Genotoxic Risks Of Liver-targeted Gene Therapy Using Recombinant AAV Vectors
Funder
National Health and Medical Research Council
Funding Amount
$891,639.00
Summary
Advances in gene transfer technology using an engineered virus known as AAV underpin success in the treatment of haemophila B, and offer the exciting prospect of treating many other liver diseases. While continued improvement of gene transfer efficiency is essential there is an equal need to focus on safety. We have discovered a genetic element in AAV that we believe is a key to unlocking accurate analysis of the safety of AAV-based gene transfer technology. Here we propose to turn the key.
Neurons are highly compartmentalized cell-types. In neurodegenerative diseases such as Alzheimer's disease, the protein Tau that serves a distinct function in one cellular compartment (the axon) accumulates in a massively phosphorylated form elsewhere (somatodendritic compartments and their spines) which is believed to impair neuronal functions. We will investigate how Tau is distributed in health and disease, and determine how this distribution is regulated.
Directed Evolution Of AAV Capsid Variants For Enhanced Targeted Genome Editing In The Human Liver
Funder
National Health and Medical Research Council
Funding Amount
$386,012.00
Summary
Liver transplantation is often the only treatment option available for patients with severe liver disease, and is complicated by a shortage of donor organs and the need for life-long drug therapy to prevent rejection. Repair of a patient’s own liver by gene therapy is a promising alternative. This project focuses on developing the technology required to undertake precise correction of genetic spelling errors in diseased liver cells without the need to first remove them from the body.
Targeting Lipids Regulated In A Setting Of Physiological Cardiac Hypertrophy
Funder
National Health and Medical Research Council
Funding Amount
$489,970.00
Summary
Existing heart failure therapies largely delay heart failure progression rather than reversing the disease. New therapeutic strategies with the ability of improving function of the failing heart are thus greatly needed. The primary goal of this study is to determine whether lipids that are secreted by the heart in a setting of “good” physiological heart growth (as occurs with exercise) can be targeted to restore function of the failing heart.
Diabetic Cardiomyopathy: Defining New Mechanisms Of Cardiomyocyte Injury And Loss
Funder
National Health and Medical Research Council
Funding Amount
$609,320.00
Summary
The heart is recognized as an important casualty organ in the progression of diabetes – both type 1 and type 2. We have new evidence that in diabetic and pre-diabetic hearts there is excess breakdown of heart cell structure in order to scavenge metabolic fuel, and that this scavenging can lead to heart cell death. Our goal is to identify ways in which the heart may be protected against this pathology and to identify new molecular targets for treatment of diabetic hearts.
