Summary
A rise in calcium and free radicals in the heart are associated with the development of heart disease. We have good evidence that a protein in the heart muscle known as the L-type calcium channel mediates changes in calcium in response to free radicals. This proposal will identify how the channel function is altered by free radicals so that a therapeutic target can be designed to prevent altered channel function and development of heart disease during increases in free radicals.
A National Population-based Study Of Rheumatic Heart Disease In Pregnancy

Funding Amount
$877,826.00
Summary
Whilst overall a rare disease, Indigenous peoples have disproportionately high rates of rheumatic heart disease (RHD). This study explores the prevalence and distribution of RHD in pregnancy in Australia and New Zealand. It details current management, diagnostic and referral process and risk factors. Key attributes of culturally safe models of care for RHD in pregnancy are explored, particularly as they relate to Indigenous women. Findings will inform policy, guidelines and education resources.
Evaluating The Genetic Contribution To Rheumatic Heart Disease Pathogenesis In Australian Aboriginal And Torres Strait Islander Communities

Funding Amount
$1,782,074.00
Summary
Rheumatic heart disease is highly prevalent in Aboriginal people in Australia and leads to early cardiac disease. Despite decades of research, the underlying genetic mechanisms for why it occurs are not well understood. We are conducting a genetic study to better understand why some people are susceptible to RHD and others are not. The study will involve substantial Aboriginal leadership and consultation and will be a model for the conduct of genetic studies in Aboriginal populations.
Exercise As Medicine For Heart Failure: A Novel Intervention To Improve Outcomes

Funding Amount
$665,585.00
Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.
AusDiab 3: Emerging Risk Factors For And Long-term Incidence Of Cardio-metabolic Diseases
Funder
National Health and Medical Research Council
Funding Amount
$2,616,397.00
Summary
This study will track 11,000 Australian adults over 12 years to determine how many develop diabetes, obesity, kidney and heart disease. The study will develop ways to best predict those who are going to develop these conditions before they have arisen, and will explore a range of novel risk factors to better understand these conditions.
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development
Funder

Funding Amount
$520,520.00
Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
Novel Insights Into The Pathobiology Of Alphavirus Infections

Funding Amount
$827,660.00
Summary
Infections with mosquito-borne viruses are increasing at an alarming rate worldwide. Ross River virus is endemic in parts of Australia, PNG and Pacific islands, while chikungunya virus is distributed globally and causes recurrent pandemics that involve millions of people. These viruses cause severe musculoskeletal disease for several months after infection. This project aims to establish how these viruses interact with the human host to cause disease and may provide a basis for new treatments.
High Penetrance Deleterious Mutations In Blinding Glaucoma

Funding Amount
$1,345,055.00
Summary
This project aims to identify the genes most commonly mutated in individuals with advanced glaucoma. Identification of such genes will lead to improved understanding of glaucoma pathogenesis, a better ability to predict risk, and the identification of drug targets for novel therapies.
Can Exercise Delay Transition To Active Therapy In Men With Low Grade Prostate Cancer? A Multi-Centre Randomized Controlled Trial.
Funder
National Health and Medical Research Council
Funding Amount
$604,429.00
Summary
Prostate cancer overdiagnosis is associated with increased rates of overtreatment and associated morbidity. Although nearly half of Australian men diagnosed with low risk prostate cancer are managed with active surveillance there are no established recommendations for slowing disease progression and delaying transition to active treatment. The proposed study would be the first to determine the efficacy of a comprehensive exercise program during active surveillance for prostate cancer.
Restoration Of Cognitive Deficits Induced By Diabetes Through The Modulation Of Cerebrovascular Integrity

Funding Amount

Summary
Diabetes is a known risk factor for the development of dementia. However the details of this association have not been known. Recent evidence consistently shows that the integrity of blood vessels in the brain may be central to the onset of dementia, and consistently, damaged brain blood vessels are often reported in diabetic patients and animal models. This project is the first to target in restoring the integrity of those brain blood vessels in order to reverse diabetes-associated dementia.
