Summary
Lymphatic vessels play important roles in vascular diseases and cancer. However, we are yet to understand how they form during development and disease. We recently identified the gene CCBE1, essential for the formation of lymphatic vessels and responsible for lymphatic dysplasia in humans. This study aims to understand the molecular pathway in which CCBE1 acts. This work aims to characterize new molecular pathways in lymphatic vessels in order to identify new therapeutic targets in lymphatic dis ....Lymphatic vessels play important roles in vascular diseases and cancer.

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

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.
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.
Understanding How GATA2 Controls Lymphatic Vessel Valve Development

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 VEGF And Vascular Formation In Craniofacial Development

Summary
Aberrant neural crest cell development gives rise to common congenital malformations such as cleft lip and/or palate and cardiac outflow tract defects that effect over 1% of all births. As the aetiology of these disorders are largely unknown it is critical to understand the cell and molecular mechanisms coordinating NCC development such that alternative therapies may be devised to target the underlying pathological defects and to provide definitive diagnostic / prognostic tools.
Bioengineering Endovascular Prostheses With Proactive Biocompatibility

Summary
Metallic cardiovascular implants, such as stents, used in the treatment of heart disease are not compatible with blood. 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 metal alloys, and shown a significant improvement in their compatibility. Stents coated using our technology stand to dramatically improve the treatment of cardiovascular disease.
The health benefits of consuming fruits and vegetables can in part be attributed to their high content of polyphenolic compounds such as flavonoids. These substances can improve functioning of blood vessels and have the potential to reduce the risk of heart disease. This project will examine one of the most common flavonoids in the diet to try and understand how it works and better understand the protective effects.
The Central Role Of Connective Tissue Growth Factor In Remodelling Of Asthmatic Airways

Summary
In the asthmatic airway an increase in the number of blood vessels can affect an asthmatic's ability to breathe. We have recently found that growth factors which can promote vessel growth are increased in the airways of asthmatics. We want to understand how these growth factors act together to possibly control the blood vessels and how their behaviour is different in the asthmatic airways compared to the nonasthmatic airways.

Anti-vascular Endothelial Growth Factor-B As A Biologic For Treating Eye Disease

Funding Amount

Summary
We plan to show that an engineered antibody fragment against vascular endothelial growth factor-B is an effective therapeutic drug for two eye diseases, corneal neovascularization and age-related macular degeneration. The innovative aspects of this approach are that it may be safer, and have a different spectrum of activity, than existing ophthalmic anti-angiogenic agents. Furthermore, it may be effective for corneal disease when administered as an eye-drop.
