The proposed research will significantly contribute to a better understanding of the wide range of physiological processes underlying mechanosensory transduction in living cells. The direct benefit for Australian science consists of: (i) strengthening international links with leading overseas laboratories, and (ii) accessing the state-of-the-art expertise not available in Australia. The acquired knowledge will aid in developing and designing artificial tactile sensors inspired by their biological models studied in this project. Long-term, the project is expected to make an original contribution towards developing new technologies and novel medical applications, both of which promise to be of great national benefit.Read moreRead less
Gene Patents in Australia: Options for Reform. Controversies over the upsurge in gene patenting, access to pharmaceuticals, biopiracy, and ownership of genetic resources, lead many to question whether patent law is appropriate for biotechnology. Do patents thwart access to beneficial technologies such as drugs, research tools and new crops, while hampering policy options for health care and agriculture? This project addresses the urgent need for a comprehensive study of the impact of biotech pat ....Gene Patents in Australia: Options for Reform. Controversies over the upsurge in gene patenting, access to pharmaceuticals, biopiracy, and ownership of genetic resources, lead many to question whether patent law is appropriate for biotechnology. Do patents thwart access to beneficial technologies such as drugs, research tools and new crops, while hampering policy options for health care and agriculture? This project addresses the urgent need for a comprehensive study of the impact of biotech patenting, critically reviewing overseas developments, setting biotechnology in the broader policy context of intellectual property law, and empirically analysing patterns rather than relying on the anecdotal and piecemeal studies that dominate this area.Read moreRead less
Unravelling the molecular diversity and evolution of centipede venoms. The project intends to improve understanding of venom evolution in centipedes. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range of animals studied, with many groups of venomous animals overlooked. One such group is centipedes, whose venoms contain diverse toxins th ....Unravelling the molecular diversity and evolution of centipede venoms. The project intends to improve understanding of venom evolution in centipedes. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range of animals studied, with many groups of venomous animals overlooked. One such group is centipedes, whose venoms contain diverse toxins that differ between taxa. This project aims to provide an insight into centipede venom evolution, and how it might be constrained by venom-gland morphology. This study seeks to contribute to our understanding of protein evolution and direct biodiscovery efforts around centipede venom.Read moreRead less
Variation in the arginine vasopressin 1a receptor (AVPR1a) gene, the social environment, general health and wellbeing. The project aims to investigate how the arginine vasopressin 1a gene affects gene expression and influences social behaviour and ultimately health and wellbeing. This research will contribute to understanding the importance of individual differences in social policy and interventions aimed at improving health and wellbeing.
Development of potent and specific modulators of the human sodium channel Nav1.7. There are few effective drugs available for the treatment of chronic pain. This team recently discovered that spider venoms are a rich source of inhibitors of Nav1.7, a new target for anti-pain drugs. The goal of this project is to develop potent blockers of Nav1.7 that can be used to critically assess the role of this ion channel in mediating pain.

A systems approach to dissect the pathogenicity and host specificity of the Fusarium wilt pathogen, Fusarium oxysporum. The pathogenic fungus Fusarium oxysporum causes wilt disease in many plant species, including many that are important for Australian agriculture. Developing environmentally friendly disease protection strategies against this pathogen requires a clear understanding of infection strategies used by the fungus to invade its host. This project, along with a parallel project in host ....A systems approach to dissect the pathogenicity and host specificity of the Fusarium wilt pathogen, Fusarium oxysporum. The pathogenic fungus Fusarium oxysporum causes wilt disease in many plant species, including many that are important for Australian agriculture. Developing environmentally friendly disease protection strategies against this pathogen requires a clear understanding of infection strategies used by the fungus to invade its host. This project, along with a parallel project in host resistance mechanisms, will provide the basis for development of a world leading platform in mechanisms of fungal pathogenicity and virulence and plant disease resistance/susceptibility. Application of the knowledge gained in this project to other host-pathogen interactions will thereby provide opportunities for improved crop protection and biosecurity.Read moreRead less
Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; a ....Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; and second, the quality of commercial fragment libraries. This project anticipates that the findings will establish a commanding role for both mass spectrometry and three-dimensional fragments in advancing FBDD approaches. It also expects to identify fragments with favourable development prospects towards the next generation of therapeutics.Read moreRead less
