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.
A Critical New Signaling Axis In Lymphatic Vascular Angiogenesis

Summary
The lymphatic vasculature is a crucial part of our vascular system required for tissue fluid drainage and maintenance of fluid homeostasis. Lymphatic vessels play major roles in vascular pathologies and in the spread of solid tumours during cancer progression. We have discovered a new molecular regulator controlling the formation of lymphatic vessels. This project will determine the signalling pathway employed by this new regulator and potential for future therapeutic applications.

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
Lymphatic malformations or cystic hygomas are growths of abnormal blood vessels called 'lymphatic vessels'. They are present at birth, commonly affect the head and neck, and can cause lifelong problems due to growth in size and frequent infections. Surgical treatment does not offer a cure, and problems often persist lifelong. The finding that blood clots are continuously forming and breaking down in these growths may provide a clue to relieving symptoms and understanding the cause of this condit ....Lymphatic malformations or cystic hygomas are growths of abnormal blood vessels called 'lymphatic vessels'.

Preventing Stroke From Arteriovenous Malformations Using Precision Thrombosis

Summary
Brain arteriovenous malformations are rupture-prone blood vessels that cause stroke in children and young adults. One third of patients have no current treatment options. We aim to develop new medicines that cause blockage of the abnormal vessels, thus preventing them from bleeding and causing stroke. Focused radiation is used to produce molecular changes in the abnormal vessels; these molecules are then the target for the new medicines. We will develop several new drugs for clinical testing.
Bioengineering Synthetic Elastin Conduits For Arterial Revascularisation

Funding Amount
$624,776.00
Summary
An arterial substitute with both physical and biological properties that mimic those of the human vasculature has long been the holy grail of vascular tissue engineering. We propose synthetic elastin can form the basis of a durable, clinically effective small diameter vascular graft and fill a significant unmet need for a biocompatible vascular substitute.

Summary
Clinically available synthetic conduits used in vascular repair and bypass are fundamentally incompatible with the vasculature. They cause inflammation at the site of implantation and increase the risk of blood clots forming. We have developed a unique method of binding bioactive protein layers to the surface of all polymeric materials and have shown a significant improvement in their compatibility.
