Involvement Of The Asciz Gene In Kidney Development And Disease

Funding Amount
$591,128.00
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.
Understanding The Developmental Basis Of Kidney Disease
Funder
National Health and Medical Research Council
Funding Amount
$622,655.00
Summary
Kidney disease is a considerable burden on the health system and much of it derives from events that occur during organ development. In this grant I will investigate why human nephron number varies between people, how renal cysts form and what genes are mutated in patients with congenital kidney malformations.
Epigenetic Hyperglycemic Cell Memory Causes Vascular Complications In Type 1 Diabetes

Funding Amount
$332,140.00
Summary
This project seeks to identify how epigenetic change in response to hyperglycemia can cause vascular complications of diabetes, and how this contributes to “hyperglycemic memory”; a phenomena where cells may undergo gene modifications which increase risk to further complications later in a patients life. These studies are the first of their kind and will characterize the types of epigenetic change that can cause human disease.
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

Funding Amount
$506,413.00
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.
Mechanisms Of Infection Triggered Renal Vasculitis

Funding Amount
$413,900.00
Summary
Kidney disease, including glomerulonephritis, is an important cause of ill-health in Australia. Some forms of kidney inflammation are linked to infection, but we don�t understand why. This project explores products from bacteria, particularly S.aureus, to work out how bacterial infection affects a form of kidney inflammation - ANCA-associated glomerulonephritis. It will establish how infection related signals activate local and immune cells, and define links between infection and the disease.
Kidney failure is a devastating consequence of diabetes mellitus. Evidence exists that increased amounts of glucose are filtered by the kidney and then together with salt is reaborbed, in patients with diabetes. The increased glucose and salt reabsorption is considered to trigger cellular damage leading to renal failure. The studies will determine if reducing glucose and salt resportion by the kidney protects against the development of renal failure in models of diabetic renal disease.
