Summary
Chronic kidney disease (CKD) is a major cause of death and disability in the Australian population. Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications. Kidney fibrosis is the final common result of diverse CK ....Chronic kidney disease (CKD) is a major cause of death and disability in the Australian population. Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications. Kidney fibrosis is the final common result of diverse CKD. This project proposes to investigate EMT, a key event in the development of renal fibrosis, whereby kidney cells are converted to fibrogenic cells. The project focuses on matrix enzymes (metalloproteinases) and E-cadherin (a molecule which is involved in adherence of kidney cells to one another, but which we think may actually be involved in the causation of EMT). This focus is novel, and could provide new understanding about the process of EMT in renal fibrosis, knowledge relevant to all diseases characterised by eventual loss of organ function due to fibrosis. It will identify new targets for therapy aimed at preventing fibrotic diseases of all types.Read moreRead less
New Treatments For Acute Kidney Injury-Targeting The IL-17A Pathway

Summary
Acute kidney injury (AKI) is a common cause of ill-health and death. Despite the frequency and seriousness of AKI no new treatments have developed over the past 40 years. While AKI can occur spontaneously it can also develop after treatment with medications, in particular cancer therapies. In this proposal we will explore the effect of new treatments to prevent AKI. We plan to identify new treatments for patients with AKI, with particular relevance to patients receiving cancer treatments.
AMP-activated Protein Kinase (AMPK) In Acute Renal Failure

Summary
Acute renal failure is a common complication of any severe illness. Generally, it is the lack of blood flow, or food that leads to this problem. People who are ill are unable to provide adequate blood flow to their kidneys, so the kidneys become diseased and fail to function. This can be fatal. There are, however, mechanisms in the kidney that are designed to avoid this shortage of energy. The aim of these studies is to find out what these protective mechanisms usually do in the kidney, and unde ....Acute renal failure is a common complication of any severe illness. Generally, it is the lack of blood flow, or food that leads to this problem. People who are ill are unable to provide adequate blood flow to their kidneys, so the kidneys become diseased and fail to function. This can be fatal. There are, however, mechanisms in the kidney that are designed to avoid this shortage of energy. The aim of these studies is to find out what these protective mechanisms usually do in the kidney, and understand why they are not more active. We hope to find ways to switch them on earleir, using drugs, so as to protect the kidneys from injury.Read moreRead less

Summary
Polycystic kidney disease (PKD) is a common genetic condition that causes fluid filled cysts to form in the kidney. In many cases, these cysts lead to kidney failure. Once the kidneys fail irreversibly, the only treatments available are dialysis and kidney transplantation. Dialysis to remove waste products from the blood is time consuming and does not completely replace all functions of the kidney. Kidney transplantation is limited by the availability of donor organs. At present, there are no re ....Polycystic kidney disease (PKD) is a common genetic condition that causes fluid filled cysts to form in the kidney. In many cases, these cysts lead to kidney failure. Once the kidneys fail irreversibly, the only treatments available are dialysis and kidney transplantation. Dialysis to remove waste products from the blood is time consuming and does not completely replace all functions of the kidney. Kidney transplantation is limited by the availability of donor organs. At present, there are no reliable ways to prevent the onset or slow the progression of PKD. The kidney consists of a complex system of tubules and ducts. PKD causes the cells that make up these tubules and ducts to grow uncontrollably and form cysts. We are using mice to study how mutations affect the mechanisms that control cell growth in the kidney and cause PKD. Bone marrow cells can move to the kidney and repair it after damage. We will test if bone marrow cells carrying a PKD mutation can cause PKD when transplanted into a healthy mouse. This will help us learn how mutations cause PKD in humans. We will also see if normal bone marrow can prevent disease when transplanted into a mutant mouse that spontaneously develops PKD. This experiment may lay the basis for a way to treat human PKD.Read moreRead less
A Mechanotransduction Apparatus To Coordinate Epithelial Collective Cell Migration.

Summary
Epithelial cells migrate as physically coherent collective groups, which is necessary for normal development and is disrupted as cancers progress to become invasive and spread. Collective migration requires communication so that the behaviour of individual cells is properly coordinated. In this project we investigate how the transmission of physical force between cells allows them to communicate; and test how its disruption contributes to cancer invasion.
