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 Pathogenesis Of Motor Neuron Degeneration Caused By A Triplet Repeat Expansion In The Androgen Receptor Gene.

Summary
Male sex hormones, or androgens, work by binding to a specific receptor, known as the androgen receptor. Androgens have an important and yet poorly understood role in nerve function. Our research is investigating how a genetic mutation in the androgen receptor causes Kennedy?s disease. This is a rare disease, affecting adult males, which causes nerves to die. The nerves which are affected are those supplying our muscles, called motor neurons. This leads to muscle wasting in the face and body.

Our research is investigating how a genetic mutation in the androgen receptor causes Kennedy?s disease. This is a rare disease, affecting adult males, which causes nerves to die. The nerves which are affected are those supplying our muscles, called motor neurons. This leads to muscle wasting in the face and body. Other symptoms include testicular wasting, reduced fertility and breast tissue enlargement. It is currently not known what causes motor nerves to degenerate in Kennedy?s disease. We are endeavouring to investigate the cause of Kennedy?s disease via the generation of a transgenic mouse carrying this mutation. It is only through a studying transgenic mouse affected by this disease can we begin to understand what is happening to nerves to cause them to die, and importantly, how can we prevent them from dying. These studies will also provide crucial information on the effects of sex hormones on nerves. As there is currently no treatment for Kennedy?s disease, an aim of this project is to investigate how we can treat this disease. This will be the first time that we can systemically test potential treatments and work toward preventing the degeneration of these nerves. Kennedy?s disease is related to a number of other neurodegenerative diseases including Huntington?s disease, which are caused by similar genetic mutations. All of these diseases are caused by degeneration of specific nerve cells. Evidence suggests that there may be similar mechanisms involved in all of these diseases. The results of this study will therefore help us to understand a range of diseases and may eventually lead to the development of therapeutic strategies to prevent their debilitating effects.Read moreRead less
Neurodegeneration In The Ageing Brain: How The Pathways Leading To Aggregated Protein Cause Disease

Summary
The team consists of eight highly experienced research scientists who are dedicated to solving the question of how the brain degenerates in the elderly when associated with the accumulation of certain proteins: e.g. A_ amyloid (Alzheimer�s disease) and PrP (Creutzfeldt-Jakob disease). Understanding the molecular pathways leading to the degeneration (loss of neuronal synapses) will permit the development of rational diagnostic and therapeutic interventions. Over the past five years the program ha ....The team consists of eight highly experienced research scientists who are dedicated to solving the question of how the brain degenerates in the elderly when associated with the accumulation of certain proteins: e.g. A_ amyloid (Alzheimer�s disease) and PrP (Creutzfeldt-Jakob disease). Understanding the molecular pathways leading to the degeneration (loss of neuronal synapses) will permit the development of rational diagnostic and therapeutic interventions. Over the past five years the program has identified several diagnostic and therapeutic avenues which are now being developed by the Pharmaceutical and Biotechnology industries. Much more research is still required for maximizing the chances of success using these approaches.Read moreRead less
The Prevalence And Trajectory Of Kidney Disease In Urban Aboriginal Children

Funding Amount
$94,515.00
Summary
The Study of Environment and Aboriginal Resilience on Child Health is a major NHMRC funded project looking at the health and illness of urban Aboriginal children in Australia. By working together with Aboriginal Community Controlled Health Services across urban and large regional centres in NSW the study team hope to better understand the causes of common diseases such as kidney and heart disease, and whether these first begin in childhood.
Computational Modelling To Understand Early-stage Neurodegeneration
Funder
National Health and Medical Research Council
Funding Amount
$645,205.00
Summary
Rather than attempting to reverse neurodegeneration, therapeutic strategies must target the earliest possible stages of disease, when treatments have the potential to prevent or slow down pathological progression. The proposed project will employ computational modelling using functional MRI to deliver highly efficient and sensitive markers of Familial Alzheimer’s disease and Huntington’s disease progression to inform when in the progression of disease clinical trials should take place.
The Causes, Treatment, And Prognosis Of Thyroid Disease
Funder
National Health and Medical Research Council
Funding Amount
$190,445.00
Summary
The thyroid gland controls body metabolism and is crucial to life. Disorders of the thyroid place a severe burden on the health system. Yet despite this, much is unknown about the causes, optimal treatments, and prognosis of thyroid disease. In this NHMRC Early Career Fellowship, Don aims to advance knowledge and improve treatments of these common conditions, focusing on thyroid cancer, Graves’ disease, and Hashimoto’s thyroiditis.
How The Environment And Epigenetics Affect The Brain Disease Gene, MAPT.

Summary
Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics".

These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether this process will have an impact on these diseases.Read moreRead less
