Summary
A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are prote ....A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are proteins, interacting with each other and with signal molecules. The next frontier in molecular biology is to identify and quantify these protein interactions. Our two institutions have a very large cohort of biologists whose research on proteins would be greatly facilitated by the Biacore 3000 and the ISS K2.Read moreRead less
Chemical and Biochemical Characterisation of Novel Iron Chelators with Therapeutic Potential. Resistance by cancers to established chemotherapeutics is a growing problem in the community and one that demands the development of new strategies. Chelators that target the essential element iron within cancer cells represent a novel and promising approach to this problem.

Resistance by cancers to established chemotherapeutics is a growing problem in the community and one that demands the development of new strategies. Chelators that target the essential element iron within cancer cells represent a novel and promising approach to this problem. The Chief Investigators represent a unique combination of expertise in coordination chemistry and the biochemistry of iron chelation. They have discovered and characterised new chelators that show marked anticancer activity, and act by a new mechanism that overcomes problems of resistance. In this project they will pursue a course that will lead to a greater understanding of how these compounds work with the outcome that new effective anticancer drugs may emerge.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.

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 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
The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells. The main stage, elongation, is regulated through phosphorylation of elongation factor eEF2 in response to hormones, amino acids and cellular energy status, via changes in the activity of eEF2 kinase. We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of ....The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells.

We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of eEF2 in controlling protein synthesis, seek new substrates for eEF2 kinase and initiate work to elucidate the structure of this unusual enzyme. This will enhance, in a range of ways, fundamental understanding of cell physiology.Read moreRead less
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.

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.

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

Chemical and Biochemical Characterisation of Novel Iron Chelators with Therapeutic Potential. Iron is essential for life, but iron-overload is a potentially fatal condition. There is no natural mechanism to excrete iron in humans, so patients suffering from iron-overload disorders are treated with the chelator Desferal to enable iron excretion typically from an early age. Desferal is orally ineffective and must be given by subcutaneous infusion (12-24h, 5-6 days/week) resulting in poor patient c ....Chemical and Biochemical Characterisation of Novel Iron Chelators with Therapeutic Potential. Iron is essential for life, but iron-overload is a potentially fatal condition. There is no natural mechanism to excrete iron in humans, so patients suffering from iron-overload disorders are treated with the chelator Desferal to enable iron excretion typically from an early age. Desferal is orally ineffective and must be given by subcutaneous infusion (12-24h, 5-6 days/week) resulting in poor patient compliance. We will conduct critical chemical and biological experiments with a new series of potentially orally active iron chelators identified in our lab. The results from this project will be vital for the development of these compounds as pharmaceuticals.Read moreRead less
