Regulation Of VEGFR Trafficking And Signal Transduction By The Ubiquitin Ligase Nedd4

Funding Amount
$388,347.00
Summary
Our recent work has discovered that the Nedd4 gene is crucial for the growth and development of blood vessels and lymphatic vessels. Our data suggest that Nedd4 controls vessel growth by regulating the levels and signalling activity of the key vascular growth factor receptors VEGFR-2 and VEGFR-3. The goals of this proposal are to define precisely how Nedd4-1 regulates the activity of these receptors and how VEGFR signalling could be better targeted to treat vascular disorders.
Improving Pain And Movement Outcomes In Symptomatic Knee Osteoarthritis

Funding Amount
$431,000.00
Summary
People fear getting painful knee osteoarthritis (OA) more than any other disease – it is seen as progressive and incurable. It often stops people from moving and staying healthy, resulting in an enormous burden on sufferers and the health care system. This program of research aims to understand what brain & nervous system processes might underlie these pain and movement problems and whether new brain-targeting treatment helps. This will allow us to better match treatment to what patients need.
There’s recent evidence that children get leaner and fitter during the school term, but become fatter and less fit over the summer holidays. This may be because of differences in activity and diet: on holidays, children may eat more, be less active and have more screen time. We propose to track the time use, diet, fitness and fatness of 9-11 year old children across three school years. If the pattern is confirmed, we should focus more on the home environment, or perhaps encourage summer camps.
Role For Zinc And ZIP2 In The Action Of Nitric Oxide And In Vascular Protection Against Cigarette Smoke And Cardiovascular Disease
Funder

Funding Amount
$685,941.00
Summary
The NO/cGMP signalling pathway, which is central to cardiovascular physiology and protection against disease, is only fully effective when there are adequate levels of zinc in the vascular endothelium. This is especially important where zinc stores are depleted (elderly, smokers, diabetics and kidney disease). There is an urgent clinical need to implement strategies to monitor vascular Zn status. This application will explore the underlying science and translate these to the clinic.
Defining The Role Of The Ubiquitin Protein Ligase Nedd4 In Vascular Development.

National Health and Medical Research Council
Funding Amount
$702,166.00
Summary
Blood and lymphatic vessels are vital components of the cardiovascular system. Abnormalities in the growth and development of these vessels are associated with human disorders including cancer and cardiovascular disease. The focus of this application is to characterise the role of the ubiquitin protein ligase Nedd4 in vascular development, with the aim of identifying targets to which novel therapeutics for the treatment of blood and lymphatic vascular diseases could be generated.
Using Online Social Technologies To Improve Health Behaviour

Funding Amount
$425,048.00
Summary
Physical inactivity and poor eating habits are leading causes of death and disease in Australia. Our health behaviours are influenced by our social networks. What’s more, Australians love social technologies, such as Facebook and smartphones. My research aims to harness these two factors to create socially-influential health programs. I will work with video game developers to develop fun and engaging interventions, and a viral marketer and leading organisations to spread the interventions.
Vascular Contributions To Dementia: Prevention In Those At High-risk
Funder

Funding Amount
$718,105.00
Summary
10,000 older adults undergo surgeries on their heart every year. These adults are at high risk for dementia, as the factors that bring them to cardiovascular surgery are the same as those that associate with dementia: hypertension, type II diabetes, etc. This population is in fact not only at increased risk of dementia due to vascular ill-health, but also because of undergoing the surgery itself. This project aims to prevent dementia in this vulnerable group.
Understanding How GATA2 Controls Lymphatic Vessel Valve Development
Funder
National Health and Medical Research Council
Funding Amount
$697,942.00
Summary
Mutations in the GATA2 gene cause human lymphoedema as a result of the crucial role that GATA2 plays in controlling the expression of genes important for building functional lymphatic vessels. Here we aim to gain a complete picture of the cellular and molecular events that are controlled by GATA2 in lymphatic vessels and in particular, in lymphatic vessel valves.
Defining The Role Of GATA2 In Lymphatic Vascular Development As A Means To Understanding How GATA2 Mutations Predispose To Human Lymphedema.
Funder
National Health and Medical Research Council
Funding Amount
$718,890.00
Summary
We have discovered that mutations in the transcription factor GATA2 result in human primary lymphedema, a debilitating disorder resulting from the failure of lymphatic vessels to return tissue fluid to the bloodstream. The goal of this application is to define the role of GATA2 in lymphatic vessels, in order to understand how GATA2 mutations cause lymphedema. Ultimately, we aim to identify targets to which desperately needed therapeutics for the treatment of lymphedema could be generated.
Active Team – Examining An Online Social Networking Intervention To Increase Physical Activity In Controlled (RCT) And Ecological (ET) Settings

National Health and Medical Research Council
Funding Amount
$814,041.00
Summary
Lifestyle diseases, such as heart disease and diabetes, are key health problems facing Australia. Effective, low-cost, mass-reach physical activity interventions are urgently needed. This project uses online social networks to deliver an innovative physical activity intervention. This project will determine how effective the software is in changing people’s lifestyle over 12 months, and whether viral marketing techniques can be used to disseminate the program on a mass scale.
