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.

Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs
Funder
National Health and Medical Research Council
Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
Assembly And Misassembly Of Mitochondrial Respiratory Chain Complex I
Funder
National Health and Medical Research Council
Funding Amount
$520,520.00
Summary
Mitochondria are the powerhouses in our cells. They burn the carbon fuels we eat and store the energy by making ATP that is used for functions such as muscle contraction and triggering of nerves. Mitochondrial Complex I is a molecular motor that helps to make ATP. “Mitochondrial disease” is often seen when Complex I is not built properly and this results in early childhood death. In this project we will study how Complex I is built and how the mitochondria responds to assembly problems.
The Role Of Accessory Subunits And Assembly Factors In The Biogenesis Of Respiratory Chain Complex I
Funder
National Health and Medical Research Council
Funding Amount
$569,987.00
Summary
The mitochondrial respiratory chain produces most of the energy required for our cells to grow and function. Complex I is the first enzyme of this chain and its defects are the most prevalent cause of mitochondrial disease, which often results in infant fatality. Defects in complex I have also been associated with Parkinson's disease and oxidative stress. This study will provide important new information into how complex I is built and what goes wrong to cause disease.
