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.

Determining the regulation of vitamin D metabolism. The proposed project will lead to a better understanding of factors that influence the biological function of vitamin D. This will impact in several areas of human health and will provide new avenues for the development of preventative approaches and treatment of cancer. This project is based on the use of 'Frontier Technologies' that will be applied to elucidate basic biological questions.
The Fine Tuned Physiology of Microaerophilic Gastric Spirilla. The aim of the project is to understand the molecular basis of fundamental properties of the physiology of enterogastric spiral bacteria of the genera Campylobacter and Helicobacter. The characteristics of these obligate microaerophiles which will be investigated are their aerobic respiratory chains, the special metabolites and enzymes involved in thiol-disulphide redox balance, and their essential requirement for carbon dioxide.

The aim of the project is to understand the molecular basis of fundamental properties of the physiology of enterogastric spiral bacteria of the genera Campylobacter and Helicobacter. The characteristics of these obligate microaerophiles which will be investigated are their aerobic respiratory chains, the special metabolites and enzymes involved in thiol-disulphide redox balance, and their essential requirement for carbon dioxide. Microaerobes include some bacteria, archea and protozoa. Realisation of the widespread habitats and importance of microaerophiles, has led recently to a vigorous interest in understanding their physiology. Knowledge of the basic properties of microaerophily has potential applications to Environmental Microbiology, Agriculture, Industrial Microbiology, Veterinary Science and Medicine.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
Characterisation of the oxygen-sensing asparaginyl hydroxylase, FIH-1, and hydroxylase-specific antagonists. This research will provide fundamental information on how cells and whole organisms can sense and respond accordingly to oxygen deficiency. This information is fundamental for our understanding of embryo development and adult life in different environments, and central to the diagnosis and treatment of diseases such as stroke, cardiovascular disease, and cancer.

Summary
A proteomics facility for Queensland researchers. The successful completion of sequencing of the genomes of many organisms, including man, has thrown emphasis back on the identification of proteins involved in the complex events that sustain cellular life. Our aim is to set up a world-class facility for proteomics research which will allow a large cohort of scientists at several institutions to identify individual proteins in vanishingly small samples of very complex mixtures. This facility wi ....A proteomics facility for Queensland researchers. The successful completion of sequencing of the genomes of many organisms, including man, has thrown emphasis back on the identification of proteins involved in the complex events that sustain cellular life. Our aim is to set up a world-class facility for proteomics research which will allow a large cohort of scientists at several institutions to identify individual proteins in vanishingly small samples of very complex mixtures. This facility will enable investigation of the control of gene expression, the intricate organisation of proteins within cells, and proteins which are potential drug targets. This equipment is an essential resource for Queensland research groups.Read moreRead less
