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.

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

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
Airway Epithelial Barrier Function, Asthma And Aero-allergen Sensitization.

Summary
There is a strong association between allergy and asthma. This association been almost universally assumed to be causative. However, recent evidence suggests an alternative explanation ie., that the abnormal epithelium in asthma allows or facilitates sensitization to airborne allergens. This project will test this alternative hypothesis using human lung tissue and an animal model.
