Summary
Atherosclerosis is a leading cause of death in Australia. The disease is caused by the formation of large deposits of cholesterol in the walls of major blood vessels. This cholesterol comes from cholesterol-carrying particles in the blood which penetrate into the tissue of the blood vessel. They are taken up by the cells of the tissue which become engorged with large amounts of cholesterol and are called 'foam cells'. These foam cells also contain a small but signficant amount of damaged (oxidis ....Atherosclerosis is a leading cause of death in Australia. The disease is caused by the formation of large deposits of cholesterol in the walls of major blood vessels. This cholesterol comes from cholesterol-carrying particles in the blood which penetrate into the tissue of the blood vessel. They are taken up by the cells of the tissue which become engorged with large amounts of cholesterol and are called 'foam cells'. These foam cells also contain a small but signficant amount of damaged (oxidised) forms of cholesterol, called oxysterols. We have found than an oxysterol called 7-ketocholesterol makes it difficult for cells to get rid of excess cholesterol. Therefore this oxysterol may be part of the reason why foam cells develop. This project will study how 7-ketocholesterol blocks cholesterol removal from cells. This may lead to the development of drugs which remove or prevent 7-ketcholesterol accumulation in the blood vessel and so prevent or reverse atherosclerosis.Read moreRead less

Using data from multiple well funded, large scale studies the team investigators will engage in two types of research; methods research and applied research. The methods research will include socioeconomic determinants of disease, systematic reviews of tests and interventions, community and patient preference elicitation, cost effectiveness modeling, and monitoring to support intervention decisions in population health. The applied research will include quantifying the effect of kidney disease on non-kidney outcomes, modeling the effect of better kidney care on population health, and preventing kidney disease in the young, old and in Aboriginal and Torres Strait Islander people. Kidney disease has been chosen because it is the interest of many of the lead applicant team, because there are excellent existing population-based databases and because it is an example of chronic disease which has a much bigger impact than on just kidney-related health outcomes alone. The training program is structured and covers initial evaluation of the goals, skills and aspirations of the team investigators, development of personal training programs, modular coursework learning from units provided by the School of Public Health at the University of Sydney, mentoring, co-mentoring, rotational placement, skills and methods support, evaluation and limited direct research funding.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

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

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

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.

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".

Funding Amount

Summary
We will investigate the mechanisms of diabetic complications related to kidney and blood vessel disease, focusing on identifying people at greater risk and ways to improve or prevent these complications. In addition, we will look at how diabetic kidney disease affects non-kidney related problems like heart disease and examine the benefit of fenofibrate on both. This greater understanding will aid further drug development in kidney and cardiovascular diseases.
