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.
The lining of the uterus is unusual compared to other parts of the adult body in that new blood vessels grow and then breakdown during menstruation every month. The aim of this project is to understand what controls the growth and regression of these uterine blood vessels. This information is of immediate relevance to a number of clinical problems where an ability to either promote or prevent blood vessel growth would be of major advantage. For example, increased blood vessel growth would accele ....The lining of the uterus is unusual compared to other parts of the adult body in that new blood vessels grow and then breakdown during menstruation every month. The aim of this project is to understand what controls the growth and regression of these uterine blood vessels. This information is of immediate relevance to a number of clinical problems where an ability to either promote or prevent blood vessel growth would be of major advantage. For example, increased blood vessel growth would accelerate wound healing, while blocking blood vessel growth would prevent the growth and spread of cancers. Another disorder that could be controlled through preventing blood vessel growth is endometriosis, a disease where cells from the lining of the uterus grow inside the abdomen causing pain and infertility. Endometriosis affects upto 10% of women.Read moreRead less
Microvascular Complications Of Diabetes - Potential Role Of Regenerative Therapies

Summary
The global burden of diabetes is projected to reach more than 366 million by 2025. According to the AusDiab 2005 study, each year 0.8% of Australians develop diabetes. Diabetes is the leading cause of end-stage kidney disease in Australia. Current treatments slow damage to the kidney, but do not reverse kidney damage. We will explore the potential for adult progenitor cells (endothelial progenitor cells) to reverse damage to the kidney and restore its function.

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

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.

Summary
This proposal brings together a team of researchers from diverse backgrounds who have already made important discoveries about the molecular control of the lymphatic system in normal physiology and cancer. The lymphatic vasculature consists of a network of vessels in organs and tissues that is critical for the regulation of tissue fluid volume and immune function. The lymphatics are also important for the metastatic spread of cancer, as they provide a route by which tumour cells spread to distan ....This proposal brings together a team of researchers from diverse backgrounds who have already made important discoveries about the molecular control of the lymphatic system in normal physiology and cancer. The lymphatic vasculature consists of a network of vessels in organs and tissues that is critical for the regulation of tissue fluid volume and immune function. The lymphatics are also important for the metastatic spread of cancer, as they provide a route by which tumour cells spread to distant sites in the body, and for lymphedema, a condition in which lymphatic dysfunction leads to swelling of tissues. This program will explore the molecular mechanisms that control the growth and differentiation of the lymphatic vessels. It will greatly enhance our understanding of lymphatic vessel growth (lymphangiogenesis) and generate a range of reagents for stimulating or inhibiting this process. These reagents will be tested in animal models for their capacity to modulate lymphatic function in the context of cancer and lymphedema.Read moreRead less
Uncovering A Novel Genetic Interaction That Governs Blood Vessel Development In Health And Disease

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.
