Summary
We have identified a 13 gene set that predicts renal transplant fibrosis and graft loss in patients. Interestingly some of these gene are donor as well as recipient related. In this project we aim to investigate these gene pathways in cell lines and animal models to better understand how the cause of renal fibrosis after transplantation.
A Novel And Unique Protein I-body For The Treatment Of Chronic Kidney Disease Through Targeting CXCR4

Summary
Chronic kidney disease (CKD) is a worldwide public health problem, with adverse outcomes of kidney failure, cardiovascular disease, and premature death. Kidney transplantation and dialysis are the only options for the management of CKD, which results in a significant burden on the health system. The central aim of this project is to develop a novel therapeutic strategy to limit/reverse CKD, which will lead to a researcher-industry partnership in discovery of novel therapeutic agent.
Renal failure is a major cause of morbidity and mortality in persons with diabetes mellitus and accounts for the majority of renal disease worldwide. Renal fibrosis is the end result of progressive kidney disease. The proposed research aims to identify a new strategy by targeting specific channels in kidney cell membranes to arrest the development of enal fibrosis and hence progressive kidney disease caused by diabetes mellitus.
New Insights Into The Role Of Renal Endothelial Dysfunction In The Pathogenesis Of Glomerular Injury And Renal Fibrosis

Summary
This project will ascertain whether abnormal function of endothelial cells contribute to diabetic and non-diabetic kidney diseases, the leading cause of end-stage kidney disease. The outcome of this study will allow us to reevaluate the role of endothelial cells in kidney scarring, lead us to question our current approaches to the treatment and management of chronic kidney disease and eventually may be helpful for the design of novel therapies to treat chronic kidney diseases.
Fibrosis is a major mechanism driving chronic disease. A specific pathologic process (TGF/Smad signalling) plays an important role in scarring of the kidney and the heart; but our understanding of this process is limited. Our exciting new data has identified a chemical modification of a component of this scarring pathway (acetylation of Smad3), and this project seeks to determine whether this modification plays a pivotal role in regulating tissue scarring.

Summary
In various kidney diseases including the most common cause of end stage kidney disease, diabetic nephropathy, identifying the molecular mechanisms responsible for kidney failure are needed to assist in defining new targets and to develop more effective treatments. The proposed studies highlight the potential of a naturally occurring endogenous molecule called Lipoxin, as a modulator of kidney injury which may provide us with a novel approach to tackle the problem of diabetic nephropathy.
Tubulointerstitial Epigenetics- The Underlying Basis Of Progressive Fibrosis In Kidney Disease

Summary
Although the kidney has capacity to repair after mild injuries, ongoing or severe injury results in scarring (so-called fibrosis) and a progressive loss of kidney function. Understanding the mechanisms that regulate the transition from repair to fibrosis is important, because once fibrosis is initiated it can be extremely difficult to switch off or reverse.
Pathogenic Role Of CDA1 Via Its Profibrotic Action In Diabetic Nephropathy

Summary
We cloned a CDA1 several years ago and found that it played a major role in controlling a series of molecular events leading to production and accumulation of extracellular matrix causing scarring, as seen in diabetic nephropathy. This project aims to study the biological functions and molecular mechanisms of CDA1 in the context of diabetic nephropathy, hence allowing us to consider CDA1 as a molecular target for drug development to treat this condition and related complications.
Targeting MicroRNA-200b In Diabetic Nephropathy Using Two Novel Delivery Systems

Funding Amount
$314,644.00
Summary
Better treatments to prevent diabetic kidney disease are prioritized by government, commercial and philanthropic sectors. MicroRNA-based strategies limit kidney fibrosis in animal models of non-diabetic kidney disease. However, current delivery systems require optimization prior to human use. We have shown that microRNA-200b suppresses kidney fibrosis. We will study two delivery systems to deliver microRNA-200b to the kidney and to study its potential to prevent or limit diabetic kidney disease.
