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 Role Of Adipose Tissue Cholesterol In Metabolic Diseases

Funding Amount
$888,340.00
Summary
Adipose tissue is important for human health. Adipose tissue can normally store a significant amount of cholesterol. Impairment of this function will cause a number of devastating diseases such as heart disease and stroke. The proposed work will help understand how adipose tissue store cholesterol. Results from this work may lead to novel therapeutic strategies against obesity and heart disease.

Summary
The statins are the ‘go-to’ drugs for treating heart disease; blocking a very early, highly-controlled step in the pathway producing cholesterol. However, they inhibit the production of other vital molecules which explains why some patients do not tolerate them. We have identified that a later enzyme in this pathway is also highly controlled and here aim to characterise the molecular mechanisms involved. This work could translate into the development of even safer drugs for treating cholesterol- ....The statins are the ‘go-to’ drugs for treating heart disease; blocking a very early, highly-controlled step in the pathway producing cholesterol.

We have identified that a later enzyme in this pathway is also highly controlled and here aim to characterise the molecular mechanisms involved.

Impact Of Advanced Glycation On Anti-atherogenic Properties Of High Density Lipoprotein

Summary
Type 2 diabetes is a rapidly growing medical problem in Australia and around the world. Diabetes affects human health through its complications and the cardiovascular complications are a cause for major concern. One of the complications is the effect on plasma lipids: it makes cholesterol carrying particles to accumulate in the blood vessels, causing atherosclerosis. We intend to investigate how diabetes modify these particles making them atherogenic.
Our goal is to discover new mechanisms involved in our cells’ delicate balancing act with respect to cholesterol levels. Understanding how production of cholesterol is controlled in our cells is key to developing new drugs aimed at preventing its excessive accumulation. This will have long-term benefits for health considering that a cellular imbalance in cholesterol is involved in two of the most common conditions threatening the health of Australians, namely heart disease and Alzheimer’s diseas ....Our goal is to discover new mechanisms involved in our cells’ delicate balancing act with respect to cholesterol levels.

I am a lipid biochemist-cell biologist determining the molecular mechanisms of disorders of lipid metabolism and developing treatments for such disorders. The diseases where lipid metabolism plays a key role include cardiovascular diseases (such as coronary artery disease), metabolic disorders (such as diabetes), some infectious diseases (such as HIV) and neurological disorders (such as Alzheimer disease).
Lipid Trafficking At Membrane Contact Sites: The Role Of Oxysterol-Binding Protein-Related Protein 5 And 8 (ORP5 And ORP8)

Funding Amount

Summary
Abnormal subcellular lipid distribution is associated with a number of common diseases including cancer, cardiovascular disease, and Alzheimer’s disease. The overall aim of this proposal is to identify and characterize new molecules that regulate the transport of lipids between different cell membranes. Results from the proposed studies will help developing novel therapeutic agents against common human diseases.
ABCA12 – A New Regulator Of Cellular Lipid Metabolism And Inflammation

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.
ABCA1 _ An Intersection Between Infection, Atherosclerosis And Metabolic Disorders

Funding Amount
$653,827.00
Summary
Pathogens interfere with cellular cholesterol metabolism in order to support their lifecycle. Such interference may cause diseases not usually associated with infection, like cardiovascular disease. Restoring normal cholesterol metabolism may help treating infection and its metabolic consequences. We will investigate molecular, cellular and physiological mechanisms of interaction of pathogens with cholesterol metabolism to find a key point that can be targeted for therapeutic intervention.

Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol. The significance of the proposed studies is that, on the one hand, they will provide new information on how 'good' lipoproteins protect us from atherosclerosis. This information can then be used to regulate 'good' cholesterol in a meaningful manner. On the other hand, the proposed studies will provide fundamental insights into how a range of lifestyle factors, physiological processes and pathological conditions relate to both the function of blood vessel-lining cells and susceptibility of individuals to atherosclerosis.Read moreRead less
