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.

From Pathogenesis To Therapeutics: Targeting Two Signalling Pathways As A Therapeutic Strategy To Treat Preeclampsia

Summary
Preeclampsia is a serious complication of pregnancy that claims the lives of thousands of mothers and babies each year. There is no efficacious medical treatment besides delivery of the baby and placenta. Our lack of therapeutics is largely a result of our poor understanding of the disease. In this application we plan to thoroughly characterise two pathways we believe responsible for preeclampsia, effectively identifying many points at which new therapies could be targeted.
Biology Of EGFR Mutations In Glioblastoma Multiforme

Funding Amount
$287,445.00
Summary
The epidermal growth factor receptor (EGFR) is a protein that has a critical role in the development of normal cells. In glioma, the most lethal of the brain cancers, the EGFR is altered. These alterations result in uncontrolled activation of the EGFR, causing signals that promote the growth and survival of brain cancer. This grant seeks to understand the nature of the signals mediated by the altered EGFR, in turn helping us develop better therapeutics for the treatment of this deadly cancer.
Signalling Networks As Targets For Antibody Therapy In Glioma.

Summary
Antibodies are a major component of the bodies immune system that bind (i.e. stick) to foreign substances such as viruses. Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells. It is also possible to generate antibodies that bind to receptors on the surface of can ....Antibodies are a major component of the bodies immune system that bind (i.e. stick) to foreign substances such as viruses. Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells. It is also possible to generate antibodies that bind to receptors on the surface of cancer cells and block their function. If you target a receptor critical to the growth or survival of a cancer cell in this way, then swtiching-off this signal may inhibit tumor growth. In this proposal we plan to test a panel antibodies that recognize receptors important to the growth of brain cancer. Two of these antibodies have been generated and the other two will be made as part of this proposal. A key aspect of this proposal will be testing these antibodies in combination to determine how many receptors need to be targeted in order to get complete tumor regressions in animal models. Overall this work will help us identify new therapeutic strategies for the treatment of brain cancer. Finally, we will also analyze the way different receptors interact together in brain cancer cells.Read moreRead less
Wnt Signaling In Dopaminergic Neuronal Connectivity

Funding Amount
$564,721.00
Summary
A major obstacle in repairing the injured or diseased brain is inducing axons (nerve cell processes) to make the appropriate connections. This is especially true following cell replacement therapy (CRT) in Parkinson's disease (PD). We will examine the processes inducing axons in the dopamine pathways to grow. We hypothesize that Wnt signaling plays and important role and that therapeutic introduction of Wnt is required to repair the dopamine pathways following CRT in PD.
Regulation Of Lipid Metabolism By AMP Activated Protein Kinase

Summary
Western communities are experiencing an epidemic of overweight and obesity that is contributing to diabetes, heart disease, and premature death. This project is investigating an enzyme, called AMP-activated protein kinase, that plays a pivotal role in controlling how our bodies control energy metabolism in response to exercise. Improved understanding about how this enzyme regulates the body's storage and breakdown of fat and responsiveness to insulin will enable the development of new medicines ....Western communities are experiencing an epidemic of overweight and obesity that is contributing to diabetes, heart disease, and premature death.

Summary
Western communities are experiencing an obesity epidemic with up to half the population being overweight. Sedentary life styles and high caloric intake are the cause and will contribute to the development of age onset diseases including obesity, diabetes, cardiovascular disease, stroke and neurodegeneration.

This project is investigating an enzyme that plays a pivotal role in controlling the body s response to exercise and diet. The key enzyme involved in this process is called the AMP-activated protein kinase. This work will increase our understanding of the health benefits of diet and exercise. This new knowledge will play a vital role in developing new therapies for promoting exercise and mitigating the effects of diet that will improve health during the ageing process.Read moreRead less
Understanding Changes In The Mammalian Prenylome Induced By Statins And Prenyltransferase Inhibitors

Funding Amount
$566,308.00
Summary
Prenylation, the covalent attachment of isoprenoid lipids to proteins, is widespread in mammalian cells. Essential for a protein's normal function, it contributes to the progression of cancer and inflammation. We have developed a novel technology to identify all prenylated proteins in the cell. Aided by this method, we will analyse the effect of statins and anti-cancer drugs on protein prenylation. This will provide guidance in identifying a more effective clinical use for them.
