Summary
The Receptor for Advanced Glycation End-products (RAGE) triggers inflammation. It was thought that this receptor was only activated from outside the cell. However, we discovered that other receptors can activate it from the inside. This is called trans-activation. During this ideas grant, we will develop innovative ways to block trans-activation of RAGE and translate these findings to make new therapeutics that are highly-relevant to he development and progression of diabetes.
A New Mechanism Of Tissue Fibrosis - A Small Peptide Regulator Of The TGF-beta1/Smad Pathway

Summary
Progressive scarring, or fibrosis, of organs leads to their loss of function. Fibrotic diseases are devastating to both the individual and our community and we lack effective therapies. We have identified a small protein, named SPRF, which represents a new mechanism in tissue fibrosis. These studies will examine the role of the SRPF protein in models of kidney, heart and lung fibrosis and its underlying mechanism of action. We will also test a therapy based on inhibiting SPRF function.
Over 2 million Australians have diabetes and up to one in three adults will develop diabetes or pre-diabetes in their lifetime with the associated burden of complications. It is not simply genetics, as the genetic variability cannot explain why some individuals and indeed some families appear to be programmed to have an inordinate burden of complications. Over the last decade we have developed state of the art technologies to characterise epigenetic changes in human clinical cohorts.
An Integrative Approach To Define And Attenuate Genomic Risk Of Coronary Artery Disease

Summary
One in four individuals that have a heart attack do not have traditional risk factors such as high blood cholesterol levels. This highlights the importance of 'family history', which we can now quantify as 'genetic risk'. These studies will determine (i) which genes are important in contributing to this genetic risk (ii) how these genes change biological pathways to increase risk and (iii) the effectiveness of modulating these biological pathways to reduce the risk of heart disease.
HTLV-1 is a lifelong infection of immune cells that sustains high infection rates up to 45% in key Australian communities. Despite HTLV-1 causing serious malignancy and inflammatory co-morbidities that shorten lifespan, few biomedical interventions are available. We will examine how the virus grows and alters immune responses to cause disease. With this, we can develop antiviral treatments to reduce virus infected cells, and make new diagnostic biomarker assays suitable for remote settings.
Structure And Biophysical Analysis Aided Design Of Novel Toxoid Vaccines For A Major Class Of Bacterial Toxins.

Summary
Inactivated bacterial toxins (toxoids), such as the tetanus vaccine, are safe and effective vaccines. Cholesterol dependent cytolysins (CDCs) are bacterial toxins produced by many important human pathogens including Group A Streptococcus (GAS) and Pneumococcus. GAS has no available vaccine and Pneumococcus does not have a universal vaccine. We have developed a new way of inactivating CDCs based on new knowledge of how they target human cells and will use this knowledge to make new vaccines.
Targeting The Crosstalk Between Metabolism And Epigenetics To Treat Liver Fibrosis

Summary
Virtually all liver disease related morbidity and mortality is a consequence of fibrosis that culminates in liver failure or liver cancer. Since anti-fibrotic drugs are not available, new approaches to drug development are required. We have discovered a novel strategy for such drug development by modifying the expression of a specific gene (RARRES1) in a highly targeted manner and thereby interrupting the energy production that is needed by cells to drive fibrosis.
Evidence For Action On Cold, Damp And Mould In Australian Homes

Funding Amount
$955,649.00
Summary
We know that living in cold and damp homes is bad for people's health. Surprisingly in Australia we do not know how much exposure to poor conditions and financial hardship combines to generate poor health at the population level. We will quantify this impact and estimate the benefit of interventions (such as mould removal and assistance for paying utility bills). This project will provide governments with evidence for tackling this housing-related health problem.
The Future In Our Hands: Screening For Preclinical Alzheimer's Disease By Analysing Hand Movements

Funding Amount

Summary
Alzheimer's disease (AD) starts damaging the brain 10-20 years before memory problems begin. By the time of diagnosis, it is hard to treat because the damage is so severe. We need a way to detect AD much earlier. We will develop a simple new computer test to detect early signs of AD by recording and analysing hand movements. Then people can start prevention earlier and scientists can research better treatments to improve people's quality of life and reduce the number of people with dementia.
Hysterectomy, Oophorectomy And Long-term Chronic Disease - The HOLD Study
Funder
National Health and Medical Research Council
Funding Amount
$690,006.00
Summary
Hysterectomy, with or without the removal of ovaries, undertaken for non-cancerous problems may have long-term consequences for other health conditions like cardiovascular disease and cancer, but existing evidence is inconsistent. This large population-based study will use linked health data from the states and the Commonwealth to investigate these associations. The information from our study will help women and their doctors to make the better-informed decisions about their treatment.
