In order to understand the factors that control cell growth and death in cancer cells signalling proteins can be identified and studied and compared with model systems from quiescent cells. Using phospholipids attached to 'fishing lines' we can search for, identify and study the function of all the downstream signalling proteins in activated cancer cells. This will provide the basic information for drug discovery processes to target specific molecules that inhibit and control the function of the signalling proteins implicated in the growth of cancer cells.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
Characterisation of molecular regulation of telomerase and telomeres by p53 in cell ageing. Telomeres, the ends of chromosomes shorten as a function of cell division, and thereby limit cell lifespan. Telomerase synthesizes telomeres and thus renders cells immortal. Recently, we found that p53, a protein with an important role in cell aging and in the uncontrolled growth of cancer, interacts with telomeres and telomerase by binding to the telomere proteins TRF1 and TRF2. This project will deciphe ....Characterisation of molecular regulation of telomerase and telomeres by p53 in cell ageing. Telomeres, the ends of chromosomes shorten as a function of cell division, and thereby limit cell lifespan. Telomerase synthesizes telomeres and thus renders cells immortal. Recently, we found that p53, a protein with an important role in cell aging and in the uncontrolled growth of cancer, interacts with telomeres and telomerase by binding to the telomere proteins TRF1 and TRF2. This project will decipher the mechanisms by which p53 regulates telomerase and telomeres, and establish the interrelationship of these proteins in regulating cell lifespan, death and immortalisation. It will provide important information for molecular intervention in cell ageing and immortalisation.Read moreRead less

It encompasses many disciplines including anthropology, education, ethology, neurology, neuroscience, philosophy and psychology. The Network will bring these disciplines together to create a forum to discuss and integrate the knowledge into a framework for understanding the mechanisms of behaviour and to stimulate cross-disciplinary research. The framework of knowledge will lead to a greater understanding of how we behave and will improve knowledge in areas which have a major behavioural component, such as in human development and education, psychological well-being, psychiatric problems and ageing.Read moreRead less
Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is call ....Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is called Senile Systemic Amyloidosis (SSA). It is not known how or why this happens. There is no cure or therapy. This project will use transthyretins from human and wallaby to explore a possible cause of SSA. If our hypothesis is correct, we will propose preventative actions to reduce the incidence of SSA in the future.Read moreRead less
Coordinating energy metabolism to enhance exercise capacity. Diet and exercise contribute to health and ageing productively whereas high caloric diets and sedentary life styles are deleterious. The enzyme AMPK regulates energy metabolism in response to diet and exercise and by studying it we expect to learn why diet and exercise are beneficial at the molecular level. This may allow the development of nutritional, exercise and drug strategies to enhance exercise capacity and well being during ....Coordinating energy metabolism to enhance exercise capacity.

The enzyme AMPK regulates energy metabolism in response to diet and exercise and by studying it we expect to learn why diet and exercise are beneficial at the molecular level. This may allow the development of nutritional, exercise and drug strategies to enhance exercise capacity and well being during ageing as well as suppress age onset diseases that include obesity diabetes cardiovascular disease hypertension and neurodegeneration.Read moreRead less
Systems therapeutics for metabolism: AMPK isoform specific drugs. Living cells have to maintain a steady balance between energy production and consumption in order to function properly. A key regulator of energy balance is an enzyme known as 5' AMP-activated protein kinase (AMPK), which regulates the burning and storage of fuels such as fat and sugars, in response to changes in energy demand. This project will provide a major advancement in our understanding of the regulation of AMPK at the mo ....Systems therapeutics for metabolism: AMPK isoform specific drugs.

This project will provide a major advancement in our understanding of the regulation of AMPK at the molecular level, and lay the foundations for the development of more effective drugs to treat energy balance disorders such as obesity and Type 2 diabetes. Furthermore, this proposal will contribute to enriching Australia's international profile and competitiveness in this important area of research.Read moreRead less
Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts ....Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts of ageing cells in tissues such as brain. Traffic jams of cholesterol transport in the secretory pathway induce early ageing of the nerve cells. We investigate a novel mechanism controlling cholesterol transport in nerve cell ageing.Read moreRead less
Novel compounds to disrupt protein-protein interactions. Many diseases involve aberrant interactions between proteins. Strategies to inhibit such interactions have potential as tool reagents for biological research but also as new therapies. Most drugs currently used in the clinic are small organic molecules, though these typically are not effective at disrupting protein complexes, hence alternatives are required.

Most drugs currently used in the clinic are small organic molecules, though these typically are not effective at disrupting protein complexes, hence alternatives are required. This proposal to examine foldamers as a novel strategy for inhibiting protein: protein interactions could lead to the development of new drugs for the treatment of diseases where the current traditional approaches have proven ineffective.Read moreRead less
