Involvement Of The Asciz Gene In Kidney Development And Disease

Summary
Congenital abnormalities of the kidney and urinary tract (CAKUT) affect more than 1/500 children. Urogenital development is primarily controlled by a small number of genes that regulate the timing and position of kidney formation. In this application we describe a novel gene involved in this process, establish where it acts, how it regulates gene expression and whether mutations in it cause CAKUT.
Generation Of Renal Cells From Human Embryonic Stem Cells

Summary
This proposal will gather evidence to show that human embryonic stem cells are capable of forming specific cell types of the embryonic human kidney. Once this is established, methods for the maintenance and directed differentiation of these cells to cell types of the mature kidney will be identified and improved. The results obtained will provide a base for future exploration of the possibility that human embryonic stem cell derived cells can be used to treat damaged kidneys.
Directed Differentiation Of Human Embryonic Stem Cells To Kidney Progenitors

Summary
In Australia, 11.3% of deaths are associated with chronic kidney disease, costing the health system >$1 billion per annum. No stem cell exists in the adult kidney that can replace damaged kidney filters. We have preliminary results suggesting we may be able to make kidney stem cells from embryonic stem cells or induced pluripotent cells. In this project, we will optimise the conditions required and test the ability of these cells to form new kidney structures.
Understanding The Causes Of Childhood Congenital Anomalies Of The Kidney And Urinary Tract

Summary
Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children. The majority of patients with CAKUT do not know the underlying cause of their renal anomalies. In this proposal we will characterise the developmental events that are perturbed in three mouse models of CAKUT and identify the causal gene responsible in each mouse model. We will translate this information to the clinic by screening patients with CAKUT for mutations in these newly identified ....Congenital anomalies of the kidney and urinary tract (CAKUT) is a common cause of renal failure in children.

In this proposal, we will use genome sequencing to identify novel mutations in patients presenting with kidney disease. We will also generate stem cell lines from these patients and their unaffected relatives in order to model the disease. Finally, we will create animal models of the same mutations. As a result, we hope to better understand the causes of the disease and begin to develop new treatment options.
Understanding How A Compromised Fetal Environment Reduces Nephron Endowment

Funding Amount
$736,901.00
Summary
The Grant will investigate how maternal diabetes and low protein diet affects the normal development of the fetal kidney with a focus on understanding how the number of nephrons in the organ are determined.
Acute injury can lead to chronic immune activation in both chronic kidney disease and in transplantation. We will study the role of a class of molecules, the purines, that are released by injury and lead to immune activation. We will focus on the molecular variations and pharmacological blockade of their receptors as potential treatments for kidney disease and transplant graft failure.
TOLERANCE OR REJECTION – THE ROLE OF INNATE IMMUNITY IN DETERMINNG THE FATE OF A KIDNEY ALLOGRAFT

Summary
Transplantation is the optimal management for people with organ failure. Tolerance, to retain transplant function without immunosuppression, remains the key goal but is seldom achieved. We propose to block Toll-like receptor signalling to achieve kidney transplant tolerance in mice. If successful, we would translate this into clinical trials in human, seeking to achieve organ transplantation without the risks of cancer, infection and premature death that are currently faced by organ recipients.
Retinal Photography To Assess Early Kidney Development In Indigenous Babies

Funding Amount

Summary
The objective of this study is to identify infants who are at high risk off subsequent kidney failure . To achieve this objective, we plan to carry out comparison of kidney growth and function between Aboriginal and and non-Aboriginal infants from birth until they are 2 years old. We also hope to determine if changes in the blood vessels in these infants' eyes correspond to changes in the growing kidney- we are trying to determine if the eyes are the windows to the growing kidneys.
The PRESERVE Trial: Prevention Of Serious Adverse Events Following Angiography
Funder
National Health and Medical Research Council
Funding Amount
$2,424,334.00
Summary
More than 75,000 coronary angiograms are performed each year in Australia. The dye used in angiograms can cause acute kidney injury (AKI); with diabetes, pre-existing kidney disease and heart failure putting people at high risk. Consequences include irreversible kidney failure requiring dialysis and risk of death. Little evidence support currently used prevention strategies. The PRESERVE Trial will recruit 5,200 people to provide definitive evidence to guide prevention of AKI.
