Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less

Confocal and single molecule microscopes for systems microscopy. This project aims to establish Australia’s first system microscopy facility with dedicated live-cell confocal and single-molecule fluorescence microscopes. In systems microscopy, the imaging workflow is automated so that large and unbiased data sets of the spatiotemporal organisation of molecules and cells can be generated.

This project aims to establish Australia’s first system microscopy facility with dedicated live-cell confocal and single-molecule fluorescence microscopes. In systems microscopy, the imaging workflow is automated so that large and unbiased data sets of the spatiotemporal organisation of molecules and cells can be generated. Combined with statistical and bioinformatics analyses, image-derived data provides system-wide information that is not easily obtainable with other approaches. The project will enable Australian researchers to image and analyse the full complexity of biological systems, potentially transforming cell biology, drug development and understanding the molecular basis of disease. It will also demonstrate how the capacity of microscopy facilities can be enhanced and bias in imaging data reduced by automating data acquisition and mining of image-based data.Read moreRead less

Summary
Many forms of pain remain poorly treated, leading to significant quality of life and economic losses. This Program grant will discover and characterise new peptides from cone snails and spiders that modulate specific channels in nerves that are critical to the transmission of pain signals to the brain. Using advanced chemical and structural approaches, promising leads will be optimised for potency and stability and evaluated in disease and pathway-specific models of pain to establish their clini ....Many forms of pain remain poorly treated, leading to significant quality of life and economic losses.

Molecular mechanisms of novel bacterial copper defense proteins. This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity. To counteract copper toxicity, bacteria have evolved defense mechanisms. The project will investigate a novel but poorly understood class of bacterial proteins, the suppressor ....Molecular mechanisms of novel bacterial copper defense proteins. This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity. To counteract copper toxicity, bacteria have evolved defense mechanisms. The project will investigate a novel but poorly understood class of bacterial proteins, the suppressor of copper sensitivity proteins, that contribute to this key virulence trait. The expected outcomes will be fundamental new knowledge of metallo-protein diversity, bacterial virulence mechanisms, and membrane protein function with potential impact on health, environment, and biotechnology.Read moreRead less

Marine snails from the waters off the Australian coast produce an amazing variety of mini-proteins in their venoms called conotoxins that they use to capture prey. These conotoxins bind very specifically to receptors in our body associated with the transmission of nerve signals. We will use natural and synthetically modified conotoxins to selectively block particular types of neuronal 'receptors' to gain a greater understanding of how the nervous system functions. This knowledge will help in the design of new drugs to treat a variety of diseases and disorders. Essentially we will use a chemical armoury developed by the cone snail to design state-of-the-art mini-protein drugs.Read moreRead less
