The sulfate anion transporter gene, Sat1: physiology, regulation and developmental expression. Sulfate is an essential nutrient for cell growth and survival. The kidneys and liver help regulate sulfate levels in the body, by yet unknown mechanisms. Recently, we cloned a gene, Sat1, expressed in mouse liver and kidneys, which may be responsible for body sulfate maintenance. In this study, we will determine the physiological importance of Sat1 in cell growth/survival and in controlling body sulfa ....The sulfate anion transporter gene, Sat1: physiology, regulation and developmental expression. Sulfate is an essential nutrient for cell growth and survival. The kidneys and liver help regulate sulfate levels in the body, by yet unknown mechanisms. Recently, we cloned a gene, Sat1, expressed in mouse liver and kidneys, which may be responsible for body sulfate maintenance. In this study, we will determine the physiological importance of Sat1 in cell growth/survival and in controlling body sulfate levels. We will generate and characterise a Sat1 lacking mouse, study its expression during development and its effects on other genes. We will elucidate how body sulfate levels are maintained and its importance in cell growth/development.Read moreRead less
Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old musc ....Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old muscles young again, is a research strategy that will promote healthy ageing and enable older Australians to enjoy a better quality of life.Read moreRead less
Structural Determinants of an Intracellular Calcium Store. Understanding the molecular interactions between key proteins in calcium signalling in muscle and the heart will allow calcium signalling to be used as a platform for a variety of purposes. These include reducing the debilitating effects of changes in calcium signalling and muscle performance in aging and in genetically- or drug-induced disorders. The project will have benefits for Australian biotechnology since it will facilitate the de ....Structural Determinants of an Intracellular Calcium Store. Understanding the molecular interactions between key proteins in calcium signalling in muscle and the heart will allow calcium signalling to be used as a platform for a variety of purposes. These include reducing the debilitating effects of changes in calcium signalling and muscle performance in aging and in genetically- or drug-induced disorders. The project will have benefits for Australian biotechnology since it will facilitate the design of novel compounds for treating muscle disorders in animals and humans, for improving meat quality and for use as insecticides. The project will facilitate graduate and undergraduate training in basic science with exposure to biotechnology, through our commercial partner Biotron.Read moreRead less
