Summary
REDUCCTION will form the basis of national action to reduce the burden of dialysis catheter associated bacteraemia, the most expensive healthcare acquired infection in the highest risk patient group, and drive savings of life and money.
Diabetic complications are the major cause of the medical burden of both type 1 and type 2 diabetes. It appears that prior episodes of poor sugar control have a sustained impact by continuing to damage blood vessels and the kidney, this phenomenon is known as metabolic memory. In this study an enzyme called Set 7 which modifies the proteins wrapping DNA is considered to play a central role in this phenomenon and could be a potential target for developing new treatments to reduce the burden of di ....Diabetic complications are the major cause of the medical burden of both type 1 and type 2 diabetes.

We have validated CDA1 as an effective target to retard kidney disease in diabetes using a mouse model where we deleted the CDA1gene. We have also developed a novel agent to inhibit CDA1 in order to retard diabetic kidney disease. In this application, we propose to confirm the efficacy of targeting CDA1 using various diabetes models and a range of strategies to target CDA1. We will also rigorously explore translation of these findings to a new treatment for diabetic renal disease.

Summary
Progressive kidney disease occurs as a result of a range of molecular and cellular pathways. One of the commonest causes of kidney disease is diabetes and this appears to be partly related to increased expression and action of certain growth factors such as CTGF. These factors promote the deposition of scar tissue in the kidney and one of the ways these promote this scarring is to change a cell s behaviour so that it now lays down collagen. This proposal will not only focus on how CTGF promotes ....Progressive kidney disease occurs as a result of a range of molecular and cellular pathways. One of the commonest causes of kidney disease is diabetes and this appears to be partly related to increased expression and action of certain growth factors such as CTGF. These factors promote the deposition of scar tissue in the kidney and one of the ways these promote this scarring is to change a cell s behaviour so that it now lays down collagen. This proposal will not only focus on how CTGF promotes scarring but will explore 2 novel factors called Snail and Slug which can act directly on particular genes such as CTGF to inhibit these deleterious effects. By further characterising these pathways involving Snail, Slug and CTGF in the kidney it will be possible to generate new targets and therapies for various forms of progressive kidney disease including diabetic kidney disease.Read moreRead less

Summary
Based in Darwin, Dr Hughes’ research focuses on improving the health and wellbeing of Aboriginal and Torres Strait Islander peoples at risk of chronic kidney disease (CKD), and those with established Chronic and end-stage kidney disease. These studies focus on participants based in both community and hospital based populations. New areas of clinical research will be addressed, as well as health systems strengthening in both primary and tertiary care systems.

Summary
Excess sugar in the blood from diabetes is detrimental and can accelerate a process where sugar attaches itself to proteins, fats and DNA. Although facilitated by high sugar, the reaction occurs happily in the presence of low sugar with high levels of free oxygen radicals. These complexes are called advanced glycation end products or AGEs. In addition, we ingest vast volumes of AGES from our diet which are taken into the blood. These AGEs are known to be involved in the development of kidney dis ....Excess sugar in the blood from diabetes is detrimental and can accelerate a process where sugar attaches itself to proteins, fats and DNA. Although facilitated by high sugar, the reaction occurs happily in the presence of low sugar with high levels of free oxygen radicals. These complexes are called advanced glycation end products or AGEs. In addition, we ingest vast volumes of AGES from our diet which are taken into the blood. These AGEs are known to be involved in the development of kidney disease in diabetic subjects. AGEs exert most of their effects on the body by binding to specific proteins, the most common and nasty of which is the receptor for advanced glycation end products, RAGE. RAGE is a known participant in other serious diseases such as Alzheimer's disease and evidence is mounting for its central role in the development of kidney disease in diabetic subjects. There is not much known about the processes which mediate RAGE which is why this is the aim of this proposal. This will enable us to stop the relentless progression of kidney disease in diabetes.Read moreRead less
In various kidney diseases including the most common cause of end stage kidney disease, diabetic nephropathy, identifying the molecular mechanisms responsible for kidney failure will greatly assist in defining new therapeutic targets in order to develop new treatments and therapies. The studies described in this proposal highlight the involvement of a novel class of small RNA molecules, and provide us with a novel approach to tackle this disease.
Kidney fibrosis is a serious complication seen in diabetic subjects. This process is mainly controlled by transforming growth factor beta (TGF-beta). However, direct targeting of TGF-beta as a therapeutic approach is inappropriate due to its other important functions. Our preliminary data show that Cell Division Autoantigen 1 (CDA1) is critical for the disease causing activity of TGF-beta. We propose to use our recently generated unique CDA1 gene knockout mouse to demonstrate this important role ....Kidney fibrosis is a serious complication seen in diabetic subjects.
