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

Understanding the mechanisms regulating calcium in skeletal muscle has important relevance for studying muscle growth and development, injury and repair, and for identifying therapeutic targets and potential therapies for ageing-related disorders, reconstructive surgery, sporting and workplace injuries, and muscle diseases. Combining cell physiology, fluorescence microscopy and digital imaging technologies for studying multicellular tissues such as skeletal muscle will enhance the international competitiveness of Australian biological research. The research will optimise development of gene delivery systems that may find eventual application for muscle wasting disorders and conditions where muscle weakness compromises quality of life.Read moreRead less
Optimising Exercise and Nutrition Throughout the Life Cycle. During the past decade the proportion of Australia's population aged 65 years and over has increased to 13% (2.7 million). During the same period, the proportion of the population aged 85 years and over has more than doubled and is now the fastest growing subpopulation in Australia. As the number of elderly persons continues to grow, sarcopenia-related conditions will have a dramatic and inevitable impact on the lives of all Australian ....Optimising Exercise and Nutrition Throughout the Life Cycle. During the past decade the proportion of Australia's population aged 65 years and over has increased to 13% (2.7 million). During the same period, the proportion of the population aged 85 years and over has more than doubled and is now the fastest growing subpopulation in Australia. As the number of elderly persons continues to grow, sarcopenia-related conditions will have a dramatic and inevitable impact on the lives of all Australians. The novel dietary protocols developed from the results of the studies undertaken in this proposal will translate into better treatment options for reversing age-dependent muscle degeneration. This is a critical first step for improving the standard of living for a large portion of Australian society.Read moreRead less

Transduction of neuronal signals by brain macroglial cells: implications for neuronal function. Study of mechanisms regulating brain cell (neuron and glial) communication is essential for understanding of normal brain function and transformations that occur in neurodegenerative states and age-related disorders. Mechanisms underlying neuron-glia communication are not well understood. By combining cell physiology, digital imaging technologies, and genetically designed and delivered molecules we w ....Transduction of neuronal signals by brain macroglial cells: implications for neuronal function. Study of mechanisms regulating brain cell (neuron and glial) communication is essential for understanding of normal brain function and transformations that occur in neurodegenerative states and age-related disorders. Mechanisms underlying neuron-glia communication are not well understood. By combining cell physiology, digital imaging technologies, and genetically designed and delivered molecules we will enhance our understanding of this brain cell communication and critical roles played by intracellular calcium. This will enhance international competitiveness of Australian biological research and provide novel insight of glial function in neurodegeneration and potential for specific therapeutic intervention in disease.Read moreRead less

Peripheral quantitative computed tomography facility for analysing bone material and structural properties. We aim to establish a facility that allows non-invasive measurement of apparent material and structural properties of small animal and human bone using leading-edge technology, peripheral quantitative computed tomography (pQCT). pQCT measurements, incorporated into our fundamental bone research will improve our understanding of the role of mechanical, environmental and local factors in re ....Peripheral quantitative computed tomography facility for analysing bone material and structural properties. We aim to establish a facility that allows non-invasive measurement of apparent material and structural properties of small animal and human bone using leading-edge technology, peripheral quantitative computed tomography (pQCT). pQCT measurements, incorporated into our fundamental bone research will improve our understanding of the role of mechanical, environmental and local factors in regulating bone and mineral metabolism and altering bone properties. This has implications for maximising bone strength and promoting optimal health throughout life. The facility will be used for a diverse range of multidisciplinary basic bone research and is vital in order to maintain international competitiveness in the field.Read moreRead less
Fluid Dynamics of Circulation: Focus on the Kidney. In Australia, about 30% of adults have hypertension, a major risk factor for heart disease, accounting for about 40% of all deaths. Problems in renal circulation are likely factors leading to hypertension. A detailed understanding of the renal circulation, of whose hydraulic characteristics we have limited knowledge, is required before we can cure or prevent hypertension. We will determine how the size, structure and geometry of the blood vesse ....Fluid Dynamics of Circulation: Focus on the Kidney. In Australia, about 30% of adults have hypertension, a major risk factor for heart disease, accounting for about 40% of all deaths. Problems in renal circulation are likely factors leading to hypertension. A detailed understanding of the renal circulation, of whose hydraulic characteristics we have limited knowledge, is required before we can cure or prevent hypertension. We will determine how the size, structure and geometry of the blood vessels influence the function of the kidney. This will lead to predictive models to aid the design and interpretation of physiological studies and the combat of hypertension. It will also help in the ongoing development of bioartificial kidneys to replace present dialysis systems. Read moreRead less

A redox sensor and triple receptor function for guanylyl cyclase. Nitric oxide (NO) protects from blood vessel spasms and clot formation. Conversely, insufficient NO occurs in cardiovascular disease. Life-saving drugs like glycerol trinitrate supply more NO to blood vessels, however these drugs are limited in their action when their target protein (NOGC) is decreased or defective, eg. in hypertension or arteriosclerosis. We have elucidated the reason for this defect and simultaneously discovered ....A redox sensor and triple receptor function for guanylyl cyclase. Nitric oxide (NO) protects from blood vessel spasms and clot formation. Conversely, insufficient NO occurs in cardiovascular disease. Life-saving drugs like glycerol trinitrate supply more NO to blood vessels, however these drugs are limited in their action when their target protein (NOGC) is decreased or defective, eg. in hypertension or arteriosclerosis. We have elucidated the reason for this defect and simultaneously discovered an entirely novel group of drugs which activate NOGC without NO. Impressively, these drugs are most effective in diseased blood vessels. The aim is the development of novel blood pressure lowering/anti-anginal drugs with higher effectiveness and less side-effects because they work in an entirely new way.Read moreRead less
