Summary
Renal failure accounts for a considerable component of the excess morbidity and mortality observed in patients with diabetes mellitus. In addition, the emotional, social and cost to the community of dialysis is enormous. PPARgamma is activated by drugs that have been recently introduced for the treatment of type 2 diabetes mellitus.

In addition, the emotional, social and cost to the community of dialysis is enormous. PPARgamma is activated by drugs that have been recently introduced for the treatment of type 2 diabetes mellitus. The propensity for these drugs to cause fluid retention has emerged recently as the most common serious adverse drug reaction associated with these compounds. the definitive cause of fluid retention with the use of PPAR gamma agonists is not known. Studies reported in the last 12 - 18 months have suggested that a common pathway may be involved in the development of the fluid retention, the high blood pressure and the scarring that occurs in the kidney. This project will be the first to provide a comprehensive examination of the effect of PPARgamma induction on renal sodium absorption and fluid retention in the human proximal tubule cells and the potential molecular mechanisms underlying them. This will provide insight as to potential adjuvant treatments for patients with diabetes.Read moreRead less
The Roles Of Ion Transporters In Sulfate Homeostasis

Summary
Sulfate is an essential nutrient for life. Individuals with autism, Alzheimers, Parkinsons and motor neurone disease have low blood sulfate levels. In this project, we plan to study several genes as candidates in controlling blood sulfate levels. We also plan to determine the role blood sulfate levels play in longevity. Our findings will make an important link between dietary nutritional intake, genes, blood sulfate levels and longevity.

Summary
Many diseases such as diabetes, cystic fibrosis, Alzheimer's and Parkinson's, results from a defect in the intracellular trafficking of specific membrane proteins. One important family of membrane proteins are the renal sulphate transporters, NaSi-1 and sat-1. They are two important proteins that control body sulphate homeostasis. Sulphate in the body is essential for cell matrix formation and cartilage-bone development and growth. Trafficking defects in these proteins can lead to changes in ser ....Many diseases such as diabetes, cystic fibrosis, Alzheimer's and Parkinson's, results from a defect in the intracellular trafficking of specific membrane proteins. One important family of membrane proteins are the renal sulphate transporters, NaSi-1 and sat-1. They are two important proteins that control body sulphate homeostasis. Sulphate in the body is essential for cell matrix formation and cartilage-bone development and growth. Trafficking defects in these proteins can lead to changes in serum sulphate levels, which results in softening of the bones, insufficient cartilage development, and changes in many metabolic processes. Using techniques of molecular and cellular biology, we aim to identify the precise the mechanisms that control the trafficking of these proteins in cells. This will enable us to determine how these proteins functions in both the normal and diseased states, which is currently unknown.Read moreRead less
A Novel And Unique Protein I-body For The Treatment Of Chronic Kidney Disease Through Targeting CXCR4

Funding Amount
$768,340.00
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.
Protein Kinases Regulate Salt Reabsorption In The Kidney

Summary
This proposal is designed to determine how the kidney senses the level of salt in the body and monitors blood pressure. This is critical for diseases such as hypertension, kidney and heart failure, where salt is retained inappropriately. We propose that the kidney uses proteins called kinases that are activated by salt in the kidney. When it is too low, they detect this and cause the kidney to absorb more salt to correct the deficiency. The way that they are able to do this has profound implicat ....This proposal is designed to determine how the kidney senses the level of salt in the body and monitors blood pressure. This is critical for diseases such as hypertension, kidney and heart failure, where salt is retained inappropriately. We propose that the kidney uses proteins called kinases that are activated by salt in the kidney. When it is too low, they detect this and cause the kidney to absorb more salt to correct the deficiency. The way that they are able to do this has profound implications for human heart and kidney disease, and biology in general.Read moreRead less
