Summary
The liver is responsible for regulating the metabolism of carbohydrates and fats, the synthesis of proteins which transport fats around the body, the synthesis of bile required for fat digestion, and for the removal of toxic chemicals from the body. Many of these processes are controlled by hormones such as adrenaline and insulin. The actions of these and other hormones on the liver involves changes in the concentration of calcium in liver cells. In a number of diseases such as diabetes, fat mal ....The liver is responsible for regulating the metabolism of carbohydrates and fats, the synthesis of proteins which transport fats around the body, the synthesis of bile required for fat digestion, and for the removal of toxic chemicals from the body. Many of these processes are controlled by hormones such as adrenaline and insulin. The actions of these and other hormones on the liver involves changes in the concentration of calcium in liver cells. In a number of diseases such as diabetes, fat malabsorption, and liver failure, the balance and regulation of calcium in liver cells is abnormal. The aims of the present experiments are to investigate the mechanisms by which hormones regulate the flow of calcium into liver cells. The experiments will involve the measurement of calcium in different regions of liver cells using fluorescent dyes and high resolution microscopy, and the identification of structural proteins and organelles within the liver cell which are required to control calcium inflow. The results should show how an important type of calcium channel in liver cells works and is controlled. This knowledge will allow better treatment of diabetes, fat malabsorption and liver failure. The knowledge should also lead to improvements in liver transplant operations.Read moreRead less

Summary
There is an urgent need to develop new drugs to treat human leishmaniasis, a disease that causes debilitating and life-threatening diseases in millions of people worldwide. This project will investigate whether it is possible to develop a new generation of drugs that target an important signaling pathway in these parasites that we have shown to be essential for virulence

Summary
Growth of the heart muscle cells occurs after heart attack and in people with high blood pressure or who suffer from diseases such as diabetes. Such growth leads eventually to the development of heart failure, a major cause of death and disability in western societies. We have identified a novel inhibitor of this growth, an enzyme that destroys a signalling intermediate called inositol(1,4)bisphosphate (or IP2). We now need to define how reduction in IP2 reduces growth and whether it provides a ....Growth of the heart muscle cells occurs after heart attack and in people with high blood pressure or who suffer from diseases such as diabetes. Such growth leads eventually to the development of heart failure, a major cause of death and disability in western societies. We have identified a novel inhibitor of this growth, an enzyme that destroys a signalling intermediate called inositol(1,4)bisphosphate (or IP2). We now need to define how reduction in IP2 reduces growth and whether it provides a useful target for therapy.Read moreRead less
