A new regional analytical biological TEM (BioTEM) will provide critical support to acclaimed medical and biological groups researching nationally significant age-related health, agricultural and environmental questions. The BioTEM, for example, will allow a unique opportunity to detect metal uptake and accumulation in bone-forming cells. This research will provide insight into metal induced afflictions, such as nasal ulcer, lung cancer, contact dermatitis and hypersensitivity reactions like asthma. The BioTEM will also be used to study how plants take up nutrients and how they use these compounds for growth, development and reproduction. Successes in this research will transfer to the important development of salt-tolerant plant species.Read moreRead less
Proteomics Analysis of Interactions Between Chaperonin 10 and Cell Surface Proteins. Specific interactions at the cell surface may induce downstream biological responses. In the case of chaperonin 10, Cpn10, interaction at the cell surface results in immunomodulation of the inflammatory response. Cell surface proteins that interact with Cpn10 have not been identified. This project will use chemical crosslinking and proteomic techniques to identify cell surface proteins that interact with Cpn10 a ....Proteomics Analysis of Interactions Between Chaperonin 10 and Cell Surface Proteins. Specific interactions at the cell surface may induce downstream biological responses. In the case of chaperonin 10, Cpn10, interaction at the cell surface results in immunomodulation of the inflammatory response. Cell surface proteins that interact with Cpn10 have not been identified. This project will use chemical crosslinking and proteomic techniques to identify cell surface proteins that interact with Cpn10 and structural features of Cpn10 involved in these interactions. These findings will providde leads for the development of immunomodulatory therapeutics based on Cpn10 interactions. Analytical technologies will be developed that are applicable to other interacting protein systems.Read moreRead less
Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, an ....Novel human tryptases: their potential role in inflammatory diseases of the young and old. We have discovered a number of novel human tryptases, and while other members of this enzyme family have been implicated in the development of inflammatory diseases (including rheumatoid arthritis), little is known about these new molecules. We aim to characterise these new enzymes by determining what part of the body they are produced in, whether they are associated with specific inflammatory diseases, and what target molecules they act on. A better understanding of these factors will increase the chances of finding cures and developing better treatments for important inflammatory diseases of the ageing population.Read moreRead less
Oxidative Damage and Cell Ageing. This research will benefit Australia by providing a fundamental understanding of how cells age. This will have immediate international impact at the scientific level and will inform strategies to reduce the rate of ageing and alleviation of age-related disorders. In the longer term the research may provide commercial and social outcomes by identifying antioxidant systems that will provide a genuine benefit in reducing ageing.
Cellular Responses to Oxidative Damage: Cell Aging. The aim of this project is to identify the mechanisms by which oxidative stress and free radical damage cause cell aging. This work will make a significant contribution to our understanding of the aging process in cells by identifying the major reactive oxygen species that contribute to cell aging, which defence systems and antioxidants provide the greatest degree of protection, what damage accumulates as cells age and which genetic systems ar ....Cellular Responses to Oxidative Damage: Cell Aging.

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
Characterisation of APC intracellular trafficking pathways. This is a fundamental research project aimed at addressing the cell biology of the APC tumour suppressor protein. APC gene mutations are directly linked to the development of colorectal cancer, a serious healthcare issue in Australia with approximately 12,400 new cases diagnosed each year and around 4,700 deaths. The severity of cases in men and women who develop colorectal cancer makes this a socio-economically serious health issue, an ....Characterisation of APC intracellular trafficking pathways. This is a fundamental research project aimed at addressing the cell biology of the APC tumour suppressor protein. APC gene mutations are directly linked to the development of colorectal cancer, a serious healthcare issue in Australia with approximately 12,400 new cases diagnosed each year and around 4,700 deaths. The severity of cases in men and women who develop colorectal cancer makes this a socio-economically serious health issue, and our project falls within the Research Priority 2: Promoting and Maintaining Good Health. If successful our project will identify localisation patterns and pathways of movement of APC within cells, which could ultimately help in development of treatments. Read moreRead less
Assessing gene function in the developing brain using zebrafish as a model system. As the average life expectancy in western countries rises there is an increasing incidence of mental health problems. Therapeutic approaches to both Alzhemier's and Parkinson's disease, as well as to brain injury following stroke, rely on a thorough understanding of how the brain develops. This is consistent with the everyday principle that if you want to fix something that is broken, then you need to understand h ....Assessing gene function in the developing brain using zebrafish as a model system. As the average life expectancy in western countries rises there is an increasing incidence of mental health problems. Therapeutic approaches to both Alzhemier's and Parkinson's disease, as well as to brain injury following stroke, rely on a thorough understanding of how the brain develops. This is consistent with the everyday principle that if you want to fix something that is broken, then you need to understand how it is put together in the first place. This project seeks to understand how the normal brain is wired together in the embryo and, in doing so it will expose novel targets for therapy in the aged.Read moreRead less
Cellular Responses to Adversity: Oxidative Stress and Protection Against Oxidative Damage. A deficiency in the protein haem oxygenase-1 causes severe biological consequences in animals and humans. These include decreased reproduction, retarded development, the inability of the body to handle iron, chronic inflammation and increased susceptibility to age-associated diseases. This study will determine how a deficiency of the protein alters cells at the level of genes, proteins and protein function ....Cellular Responses to Adversity: Oxidative Stress and Protection Against Oxidative Damage. A deficiency in the protein haem oxygenase-1 causes severe biological consequences in animals and humans. These include decreased reproduction, retarded development, the inability of the body to handle iron, chronic inflammation and increased susceptibility to age-associated diseases. This study will determine how a deficiency of the protein alters cells at the level of genes, proteins and protein functions. By doing so, the project will illuminate how haem oxygenase-1 alters cell functions in a beneficial way. This information will eventually assist in preventing the serious disorders associated with deficiency of haem oxygenase-1. It will also provide the basis for novel treatments to slow down age-associated diseases.Read moreRead less
