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
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.
Probing membrane rafts using surface-selective multi-dimensional microscopy. The results of this project will provide fundamental insights into the role played by domains in cell membranes in the regulation of membrane protein function. These insights will create new avenues in the biotechnology industry for development of novel therapeutics aimed at disruption of membrane protein-protein interactions that cause aberant cell signalling in disease states such as cancer.
Structure and dynamics of a multiprotein-mRNA complex involved in the regulation of gene expression. RNA/protein interactions are now recognised as a major control point in the regulation of gene-expression. Proteins such as HuR and the poly(C)-binding proteins (PCBPs) act to stabilise and transport specific messenger (m)RNAs, and thus determine their translation levels. In contrast to such an important function, very little is known about these protein/mRNA interactions at an atomic level. The ....Structure and dynamics of a multiprotein-mRNA complex involved in the regulation of gene expression. RNA/protein interactions are now recognised as a major control point in the regulation of gene-expression.

In contrast to such an important function, very little is known about these protein/mRNA interactions at an atomic level. The current study will investigate the structural and biophysical properties of a recently discovered HuR/PCBP/mRNA complex implicated in the regulation of androgen receptor expression. This information has the potential to assist in the development of drugs to reduce AR expression in prostate cancer.Read moreRead less
The effect of mitochondrial and nuclear-cytoplasmic variation on longevity, metabolism and stress resistance in Drosophila. Much research points to a major role of free radical damage in aging, thus the belief that antioxidants might be beneficial in delaying aging. Free radicals are mostly formed in the subcellular organelles which consume oxygen and produce energy, and this may be the major site of age-related damage. This project seeks to understand the degree to which variation among these ....The effect of mitochondrial and nuclear-cytoplasmic variation on longevity, metabolism and stress resistance in Drosophila.

Free radicals are mostly formed in the subcellular organelles which consume oxygen and produce energy, and this may be the major site of age-related damage. This project seeks to understand the degree to which variation among these subcellular organelles affect free radical damage and aging, using the fruitfly Drosophila melanogaster as a model organism.Read moreRead less
Involvement of cell coupling in vascular function: Development of a computational model. Gap junctions are intercellular channels which enable the production of coordinated responses in multicellular tissues and organs. Blood vessels are comprised of endothelial cells surrounded by smooth muscle cells and gap junctions exist within and between these layers. The present proposal will determine the fundamental role of gap junctions in regulating blood flow and blood pressure. Our data will enable ....Involvement of cell coupling in vascular function: Development of a computational model. Gap junctions are intercellular channels which enable the production of coordinated responses in multicellular tissues and organs. Blood vessels are comprised of endothelial cells surrounded by smooth muscle cells and gap junctions exist within and between these layers. The present proposal will determine the fundamental role of gap junctions in regulating blood flow and blood pressure. Our data will enable us to develop a computational model of the vascular wall and so predict how changes in electrical properties, as occur during pressure changes, can influence blood flow. Since ageing is accompanied by an increase in blood pressure, our results will contribute to a better understanding of blood flow regulation in our ageing population.Read moreRead less

The project will will enable Australia to take the lead in the global analysis of oligotrophy, highlighting the reputation Australian scientists have in scientific programs of global significance. As Australia is surrounded by some of the most oligotrophic waters in the world, we have access to an enormous natural resource suitable for the isolation of oligotrophs. Realising the potential of oligotrophs may therefore provide an invaluable source of compounds, enzymes and molecules for biotechnology and industry. Understanding microbial oligotrophy will also ensure we protect our $50 billion dollar tourism industry by remaining abreast of factors which influence the marine environment and directly impact on all coastal activities.Read moreRead less

The project will identify the factors that contribute to TeraHertz contrast in soft tissue cell cultures, thereby developing a non-invasive imaging system to show contrast between diseased and healthy cells. This is a fundamental step towards a system for diagnosing disease states of skin cells, for example, the early detection of melanoma. Ultimately, Australia will benefit from a new technology, and new diagnostic biomedical techniques, for rapid, non-invasive and reliable skin cancer diagnosis.Read moreRead less
Adaptive Evolution of BRCA1 in Ancestral Mammals. This project investigates adaptive evolution of BRCA1 in the early radiation of mammals. We will test the hypothesis that the evolution of mammary glands and X chromosome inactivation has resulted in modification of the BRCA1 protein sequence as it aquired new roles in these processes. We will also investigate the importance of these changes inducing compensatory changes in other parts of the protein.

Summary
800 MHz NMR spectrometer for biomolecular structure-function analysis. An understanding of how organisms function at the molecular level is central to developing the ability to fight many diseases in a rational way. This equipment will provide the capability for many different laboratories around NSW and the ACT to advance our knowledge at this fundamental level, primarily by examining the structures and functions of biomolecules such as proteins.
