Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain ....The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
Optimising dissolved air flotation (DAF) for algae removal by bubble modification in drinking water and advanced wastewater systems. Algal blooms in potable water reservoirs and advanced wastewater treatment lagoons can impact the performance and economic viability of water treatment processes resulting in taste and odour episodes and the risk of algal toxins as well as causing further limitation to already stressed water resources in Australia. This project aims to develop an adaptation of the ....Optimising dissolved air flotation (DAF) for algae removal by bubble modification in drinking water and advanced wastewater systems. Algal blooms in potable water reservoirs and advanced wastewater treatment lagoons can impact the performance and economic viability of water treatment processes resulting in taste and odour episodes and the risk of algal toxins as well as causing further limitation to already stressed water resources in Australia. This project aims to develop an adaptation of the dissolved air flotation process that is already used for algae treatment that will provide a more robust, economic and sustainable barrier to algal cells in accordance with the Australian Drinking and Recycled Water Guidelines.Read moreRead less
Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. 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 gr ....Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. 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

This project aims to establish a high-throughput, automated patch clamp facility to enable research at the forefront of cell phenotyping and drug discovery. Ion channels are membrane proteins that underlie cell function and are therefore important drug targets. The patch clamp technique is the most powerful tool available to functionally characterise cells and study the function of ion channels. The significant advance provided by the high-throughput, automated patch clamp system is that it allows up to 384 cells to be recorded simultaneously. This project expects to enhance capacity to automate and standardise the quality of recordings, substantially increase the rate of data production, and enable greater access to patch clamp technology.Read moreRead less
Nicotinic receptor structure and function probed with conotoxins. Nicotinic receptors are intrinsic membrane proteins that play a role in communication in excitable cells, particularly in the nervous system.

The primary goals of this project are to define the structural and functional determinants of nicotinic-conotoxin interactions at a molecular level, and develop new selective probes that advance neurophysiological research. The diversity and distribution of nicotinic receptor subtypes being uncovered through molecular biology and selective conotoxin probes presents an exciting opportunity for the discovery of new therapeutic agents.Read moreRead less
