Regulatory mechanisms for calcium release-activated calcium channels. Store-operated calcium channels play a central role in the functions of all animal cells. They participate in generating the cellular responses to hormones, growth factors and other physiological stimuli. The aims of this project are to elucidate the mechanisms that regulate the activity of store-operated channels and how their properties can be modulated by different pharmacological agents.

They participate in generating the cellular responses to hormones, growth factors and other physiological stimuli. The aims of this project are to elucidate the mechanisms that regulate the activity of store-operated channels and how their properties can be modulated by different pharmacological agents. Using chiefly the techniques of electrophysiology and molecular biology we expect to learn the fundamental mechanisms that modulate the opening and closing of store-operated calcium channels and to gain an important information that can be used for determining the molecular structure of these channelsRead moreRead less

This project uses transgenic plant technology to elucidate how mitochondrial function impacts on the profile of metabolites in plant cell and tissues and whether altering these profiles influences a plant's ability tog row in harsh conditions. It will contribute to our fundamental knowledge of plant metabolism using a metabolomic anaylsis of plant stress response. This will be achieved using new high-throughput technologies, allowing reliable qualitative and quantitative analysis of large numbers of samples. This approach will compliment existing genomic and proteomic analyses of plants exposed to abiotic stress.Read moreRead less

Gating and permeation in ClC channels. Chloride ion channels are essential proteins in all living cells but, compared to other channels, little is known of their structure or how this defines and controls chloride transport. We will produce both normal and structurally modified (mutant and known to cause disease) chloride channels in cultured cells by genetic engineering so that we can analyse channel function using a combination of electrophysiological and chemical methods. We expect to learn ....Gating and permeation in ClC channels. Chloride ion channels are essential proteins in all living cells but, compared to other channels, little is known of their structure or how this defines and controls chloride transport. We will produce both normal and structurally modified (mutant and known to cause disease) chloride channels in cultured cells by genetic engineering so that we can analyse channel function using a combination of electrophysiological and chemical methods. We expect to learn which channel parts are fundamental and how subtle changes in structure can alter the opening and closing of these channels and the way that chloride passes through them.Read moreRead less
The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search fo ....The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search for new reflectors, and that's an aim of this project. And since reflectors are often difficult to make, why not let animals make reflectors for us? That is a further aim of this project. Soon we may have genetically-altered butterfly scales embedded in our credit cards that cannot be counterfeited.Read moreRead less

Tissue Therapies Ltd has shown that a patented combination of three biosynthetic molecules, VitroGroR, can promote tissue repair effectively. This project will use biophysical and biochemical techniques to investigate precisely how these molecules interact, and hence provide a rational basis for future developments and improvements of this exciting new therapeutic strategy.
Conversely, this information would also facilitate the development of antagonists to VitroGroR complexes would provide novel opportunities to treat diseases such as cancer and atherosclerosis that involve excessive production of its component molecules.Read moreRead less
Structural studies of the interactions of actinin-4 and intracellular signalling proteins. The intracellular signalling cascade plays important roles in cellular processes such as growth and differentiation by exerting changes in gene expression or remodelling of the intracellular protein framework. The actin-based cytoskeleton is one such network of proteins responsible for a number of processes including cell division, migration and adhesion to other cells and tissues. This proposal aims to un ....Structural studies of the interactions of actinin-4 and intracellular signalling proteins. The intracellular signalling cascade plays important roles in cellular processes such as growth and differentiation by exerting changes in gene expression or remodelling of the intracellular protein framework. The actin-based cytoskeleton is one such network of proteins responsible for a number of processes including cell division, migration and adhesion to other cells and tissues. This proposal aims to understand how actinin-4, a component of the actin cytoskeleton in non-muscle tissues, interacts with and is stimulated by proteins of the intracellular signalling cascade.Read moreRead less

This study will improve our understanding of the interactions of Insulin-like Growth Factors (IGFs) with their principal receptor, the IGF-1R. A sound understanding of these interactions is essential for the development of non-peptide IGF antagonists designed for therapeutic applications. Such molecules could lead to new therapeutic approaches for diseases in which dysregulation of the IGF system has been implicated including cancer, diabetes and atherosclerosis.
Since IGFs are major determinants of growth, the outcomes of this project could also lead to improvements in animal production with major benefit to primary industry. New IGF analogues developed could assist biotechnology exports.
