This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiatives in developmental and cellular biology. This large-scale, high-resolution expression profiling infrastructure is required to maintain international competitiveness and will dramatically improve our gene discovery, functional assessment and understanding of vertebrate development.Read moreRead less
Structure and function of a new class of multi-zinc finger (MZF) transcriptional regulators. An understanding of how genes are switched on and off during the development and lifetime of an organism is central to developing the ability to fight many diseases in a rational way. This project will advance our knowledge in this area at a fundamental molecular level by examining the mechanisms through which a specific set of proteins controls gene expression.
Phospholipids and kinases as regulators of epithelial sodium channels. The intracellular signalling pathways that will be identified in this project will facilitate the development of novel therapies for the many conditions in which the activity of epithelial sodium channels is abnormal. These include influenza, otitis media, high blood pressure and cystic fibrosis. It will also provide training for post-doctoral fellows and research students in a number of the key techniques in modern cellular ....Phospholipids and kinases as regulators of epithelial sodium channels.

Regulation of Stress Hormone Receptors in the Brain. Our research will provide information on how the brain controls our response to stress and will allow the development of targeted strategies to reduce the possibility during chronic stress of the development of conditions such as anxiety and depression. This will improve mental health outcomes in Australia and add to Australia's economic and social stability.
Investigating the mechanisms of flavonoid actions on glycine receptors. The research to be conducted in this project will use state-of-the-art electrophysiological and molecular biological approaches to carefully characterise the actions of certain flavonoid compounds on the glycine-receptor channel. These compounds have recently been reported to act as modulators of ligand-gated ion channels, proteins integral to brain function and disease. However, no-one has studied in any detail the mechan ....Investigating the mechanisms of flavonoid actions on glycine receptors. The research to be conducted in this project will use state-of-the-art electrophysiological and molecular biological approaches to carefully characterise the actions of certain flavonoid compounds on the glycine-receptor channel. These compounds have recently been reported to act as modulators of ligand-gated ion channels, proteins integral to brain function and disease. However, no-one has studied in any detail the mechanisms by which these compounds act. By discovering their site and mechanisms of action we will further our understanding of these important proteins and their modulation, maintain Australia's significant expertise in this field and provide leads for future development of drugs with potential therapeutic value.Read moreRead less

Characterization of erythroid differentiation related factor (EDRF): a novel a-globin binding protein. Hemoglobin, a four-subunit protein comprising two alpha and two beta polypeptide chains, is the essential oxygen transporter found in all mammals. Problems with the synthesis of hemoglobin can give rise to a range of common and serious human disorders, including thalassaemia and anemia. We have discovered a protein, EDRF, that appears to interact directly with alpha-globin (but not beta-globin) ....Characterization of erythroid differentiation related factor (EDRF): a novel a-globin binding protein. Hemoglobin, a four-subunit protein comprising two alpha and two beta polypeptide chains, is the essential oxygen transporter found in all mammals. Problems with the synthesis of hemoglobin can give rise to a range of common and serious human disorders, including thalassaemia and anemia. We have discovered a protein, EDRF, that appears to interact directly with alpha-globin (but not beta-globin) and to play a role in the regulation of hemoglobin production. We now seek to understand the nature of this interaction at a molecular level and mechanistic level.Read moreRead less
Functional imaging of colour pathways in the living eye. In order to repair or regenerate a diseased eye, we require knowledge of the normal pattern or nerve cell connections, and knowing how biology solves the problem of colour vision can be used to improve the design of artificial vision systems. The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's re ....Functional imaging of colour pathways in the living eye.

The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's research and development capacity in this new area of medical diagnostics. Our machine will be made available to other Australian laboratories and will improve the national capacity for making further scientific discoveries about how the visual system works.Read moreRead less
Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes.

Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less
Quantum mechanical and dynamical investigation of ion channels. Many genetic diseases result from mutations in the genes that transcribe the channel proteins. Ion channels are also primary targets for development of therapeutic drugs for many ailments.

Development of proper simulation tools is essential for a molecular-level understanding of their operation, which will be very helpful in finding treatments for genetic diseases as well as new drugs that target ion channels. Another aim of the project is to provide research training in computational biology. Research in this area is rapidly growing elsewhere but it has been rather neglected in Australia, and there is a shortage of researchers with such skills at present.Read moreRead less
