The development of a rapid diagnostic test for heparanase activity. Heparanase is an enzyme that has been implicated in a number of disease states such as cancer, arthritis, multiple sclerosis and other inflammatory diseases. Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this a ....The development of a rapid diagnostic test for heparanase activity. Heparanase is an enzyme that has been implicated in a number of disease states such as cancer, arthritis, multiple sclerosis and other inflammatory diseases. Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this assay could provide a useful diagnostic tool in a clinical environment that would allow for the rapid assessment of these diseases, their progression and indeed response to therapy.Read moreRead less
Development of a novel high yield cell-free protein expression system. Recombinant proteins are used as vaccines, drugs, and research tools, as well as food and detergent additives, comprising a A$100 billion international market. Their production requires laborious, expensive, and time-consuming construction of transgenic organisms or cells. Alternatively, recombinant proteins can be produced in extracts prepared from cells or organisms.

Recombinant proteins are used as vaccines, drugs, and research tools, as well as food and detergent additives, comprising a A$100 billion international market. Their production requires laborious, expensive, and time-consuming construction of transgenic organisms or cells. Alternatively, recombinant proteins can be produced in extracts prepared from cells or organisms. The aim of this proposal is to develop a new technology that will make cell-free production of recombinant proteins rapid, cheap, and scalable. This will advance Australia’s intellectual leadership in the area of biotechnology and will bring numerous economic benefits by accelerating pharmaceutical development. Read moreRead less
Identification of novel biomarkers in tears for prostate cancer diagnosis and prognosis. The purpose of this study is to identify novel biomarkers in the tears of patients with CaP. The use of the several techniques will increase the chance of success and enable us to find more diagnostic markers. If successful, the identified proteins may be used to diagnose and determine the stage of cancer. This will help guide clinicians in choosing the best treatment methods for an individual patient.

The use of the several techniques will increase the chance of success and enable us to find more diagnostic markers. If successful, the identified proteins may be used to diagnose and determine the stage of cancer. This will help guide clinicians in choosing the best treatment methods for an individual patient. The markers may also be used to monitor the disease progress and the effects of treatment. The results from this study may improve the prognosis of CaP patients.Read moreRead less
Understanding the role of a newly recognised retrovirus in the induction of cancer and immunosuppressive disease in koalas. Leukaemia, lymphoma and opportunistic infections are major causes of mortality in both captive and wild koala populations. It is our hypothesis that a recently discovered retrovirus is responsible for these disease syndromes. Using a multidisciplinary approach, this project will determine viral parameters that correlate with the disease status of koalas and lead to improvem ....Understanding the role of a newly recognised retrovirus in the induction of cancer and immunosuppressive disease in koalas. Leukaemia, lymphoma and opportunistic infections are major causes of mortality in both captive and wild koala populations. It is our hypothesis that a recently discovered retrovirus is responsible for these disease syndromes. Using a multidisciplinary approach, this project will determine viral parameters that correlate with the disease status of koalas and lead to improvements in diagnosis and management of disease in koala populations. The planned research will also provide some insight into cross-species transmission of retroviruses.Read moreRead less
Gene Expression Profiling and de novo Transcriptome Sequencing using Geneballs. The purpose of the project is to demonstrate that bead-based technology can be used in applications that currently require DNA hybridisation in order to overcome existing deficiencies in microarray technology. By providing the capability to quickly and efficiently produce, screen and utilize biomolecule libraries of nearly unlimited size, this technology provides the key to unlock the power of genomics and proteomics ....Gene Expression Profiling and de novo Transcriptome Sequencing using Geneballs. The purpose of the project is to demonstrate that bead-based technology can be used in applications that currently require DNA hybridisation in order to overcome existing deficiencies in microarray technology. By providing the capability to quickly and efficiently produce, screen and utilize biomolecule libraries of nearly unlimited size, this technology provides the key to unlock the power of genomics and proteomics for use in real world applications. The project has two aspects. First, relatively small directed cDNA-bead libraries will be compared to known low-density cDNA microarrays to validate the technique for utility in gene expression profiling. Secondly, large libraries containing short oligonucleotide sequences will be used for de novo sequencing of a complete transcriptome. Proof-of-concept in either case will pave the way for many genomic applications and catapult the technology to 'blockbuster' status.Read moreRead less

Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity ....Development of a new diet to improve insulin sensitivity and manage weight in healthy cats. This project will determine if a low carbohydrate, moderate fat, high protein diet improves insulin sensitivity and reduces weight gain in cats compared to a typical high-carbohydrate grocery line diet. It will identify risk factors for weight gain such as increased fasting insulin concentration and will also determine which simple assessment of insulin sensitivity best correlates with insulin sensitivity measured by a gold standard. This project should lead to the formulation of a diet designed to improve insulin sensitivity and minimize weight gain in cats, and allow for earlier identification of cats at risk of obesity.Read moreRead less
Retroviral invasion of the koala genome: prevalence, transmission and role in immunosuppressive disease. Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease.

Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease. Lymphoid cancers and opportunistic infections are significant diseases in both captive and wild koala populations. We previously demonstrated that the recently identified koala retrovirus is associated with lymphoid cancer in koalas. This project will determine the distribution of the virus in Australia, the mechanism of its spread and its effect on the immune function of koalas. This research will provide a foundation for better management of captive koalas and for conservation of wild koalas.Read moreRead less
