Summary
Vascular permeability or leak is a major problem in diseases such as cancer and in cardiovascular diseases . MicroRNAs (miRNAs) are small control genes that influence dveleopment and disease. We have identified a miRNA cluster in endothelial cells, the cells that line the blood vessels, that is important in the control of vascular leak. This project is focused on understanding the impact of these miRNAs in disease.
Vascular Targeting Combined With Radiosurgery In An Arteriovenous Malformation Rat Model

Summary
Cerebral arteriovenous malformations are an important cause of stroke and brain bleeds. In many patients such a stroke can result in severe disability or death. Current management involves a combination of surgery, radiation therapy and endovascular treatments and carry a high risk of complications. This research project suggests a new form of treatment whereby irradiating the vascular malformation a medication could be administered to cause targeted clotting of the malformation.

Summary
The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment h ....The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment has returned glucose levels towards normal.Read moreRead less
Congenital brain vascular malformations are a common cause of stroke and death in young patients. This project aims to develop a new treatment for these lesions that does not require surgery. We will use focussed radiation to change the cells lining the abnormal vessels so that they can be targeted with a new treatment that causes blockage of the vessels and prevents haemorrhage.
Role For Zinc And ZIP2 In The Action Of Nitric Oxide And In Vascular Protection Against Cigarette Smoke And Cardiovascular Disease

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.
Uncovering A Novel Genetic Interaction That Governs Blood Vessel Development In Health And Disease

Funding Amount
$626,557.00
Summary
Blood vessels are a vital component of the cardiovascular system. Abnormalities in the growth and development of blood vessels are associated with human disorders including cardio-vascular disorders, cancer and inflammatory diseases. The focus of this application is to determine the molecular events that direct the construction of the blood vascular tree, with the aim of identifying targets to which novel therapeutics for the treatment of blood vascular diseases could be generated.
Therapeutic Potential Of Inhibiting Eph/ephrin Signalling To Repair The Vascular Endothelium In Septic Shock

Funding Amount
$664,734.00
Summary
Septic shock is a life-threatening condition usually caused by bacterial infection in the bloodstream. More than 5000 people, including 500 children, die from sepsis each year in Australia. Worldwide, it is the most significant cause of death in children. Sepsis is associated with leakage of fluid and proteins through the cells lining the blood vessels. This project will develop and test a novel treatment for sepsis which focuses on reducing this leakage by blocking the Eph/ephrin proteins.
