Summary
Renal dysplasia and renal cystic disease remain significant clinical problems in the paediatric population. Initial animal experiments have demonstrated that inhibiting the renal vasoactive peptide angiotensin during development results in a form of medullary cystic disease. The experiments in this project are aimed at understanding the specific roles and interactions that angiotensin plays in renal development, particularly in development of the distal nephron, the vasculature and the renal pel ....Renal dysplasia and renal cystic disease remain significant clinical problems in the paediatric population. Initial animal experiments have demonstrated that inhibiting the renal vasoactive peptide angiotensin during development results in a form of medullary cystic disease. The experiments in this project are aimed at understanding the specific roles and interactions that angiotensin plays in renal development, particularly in development of the distal nephron, the vasculature and the renal pelvis. Importantly the time course of growth and differentiation of these structures varies and the time course of inactivation of angiotensin may result in different malformations. Information from these studies will allow us to understand how clinical problems can arise when angiotensin is absent or other players modify its action. Such situations can arise in humans through sporadic genetic mutations that may well not manifest in widespread clinical abnormalities.Read moreRead less

Summary
Chronic kidney disease is a growing burden to the health system. The long term health of your kidneys is influenced by the number of functional units, nephrons, present in each kidney, a feature that is determined before birth. If we could influence this number, we may be able to reduce the risk of kidney disease in later life for at risk populations, including the Aboriginal community. This study will investigate the stem cells that form the nephrons, how the process occurs and how it can be in ....Chronic kidney disease is a growing burden to the health system.

Summary
Crim1 is a novel protein which appears to regulate the activity of growth factors and therefore affects the normal development of a number of organs. It is particulrly involved in normal development of blood vessels. A greater understanding of how growth factor activity is modulated by Crim1 will have significance to almost every developmental and disease state involving such growth factors. The potential for Crim1 to link the activity of several distinct growth factor pathways may explain tissu ....Crim1 is a novel protein which appears to regulate the activity of growth factors and therefore affects the normal development of a number of organs. It is particulrly involved in normal development of blood vessels. A greater understanding of how growth factor activity is modulated by Crim1 will have significance to almost every developmental and disease state involving such growth factors. The potential for Crim1 to link the activity of several distinct growth factor pathways may explain tissue specific differences in growth factor responses. These basic advances in understanding will have implications for many disease states, including renal disease, vascular disease and cancer.Read moreRead less
Active Lung Disease In Survivors Of Preterm Birth? Can We Treat It?

Summary
More than 15 million babies are born preterm each year. Those that survive face a lifetime of ongoing breathing problems and lung function that worsens through childhood. Our study will work out how inflammation in the lungs contributes to these ongoing breathing problems during childhood. We will also look at how the exhaled breath of preterm children is different to term children and test how treatment with an inhaled anti-inflammatory medicine changes the lung disease in preterm children.
Understanding And Improving Treatment Of Premature Infants To Improve Long Term Outcomes

Summary
The last 2 decades heralded many important advances in the care of preterm infants but important gaps in our knowledge remain. Studies undertaken in the preclinical and clinical settings during this Fellowship will enhance understanding of the complex nature of disease in preterm infants. Further, we will develop and evaluate new treatments that enhance growth and development of the premature baby to optimise their long term intellectual, physical, emotional and social outcomes.
A Novel And Unique Protein I-body For The Treatment Of Chronic Kidney Disease Through Targeting CXCR4

Funding Amount
$768,340.00
Summary
Chronic kidney disease (CKD) is a worldwide public health problem, with adverse outcomes of kidney failure, cardiovascular disease, and premature death. Kidney transplantation and dialysis are the only options for the management of CKD, which results in a significant burden on the health system. The central aim of this project is to develop a novel therapeutic strategy to limit/reverse CKD, which will lead to a researcher-industry partnership in discovery of novel therapeutic agent.
The Role Of Tissue Hypoxia In The Evolution Of Kidney Disease

Summary
We will determine how low oxygen levels in the kidney lead to kidney disease. We can now measure the levels of oxygen in kidney tissue in rats 24 hours a day, 7 days a week, in a completely non-invasive way. We will study two common kinds of kidney disease. One, acute kidney injury, can result from administration of contrast agents used in x-ray diagnostic procedures. The other, chronic kidney disease, is common in patients with diabetes or high blood pressure.
