Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will im ....Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will improve our mechanistic understanding of genetic diseases in populations. In addition, this proposal is expected to lead to identification of potential targets and technologies that would be of interest to Australian industry.Read moreRead less

FishWorks represents a large-scale co-operative initiative to develop state-of-the-art zebrafish housing, manipulation, genomics and screening infrastructure in Australia. This will both support and further enhance a core group of high quality researchers to engage in cutting-edge research in areas of acknowledged expertise as well as priority within their respective institutions. In addition, it will facilitate wide-ranging collaborative arrangements to further develop and exploit this research area.Read moreRead less
Regulation of Stress Hormone Receptors in the Brain. Our research will provide information on how the brain controls our response to stress and will allow the development of targeted strategies to reduce the possibility during chronic stress of the development of conditions such as anxiety and depression. This will improve mental health outcomes in Australia and add to Australia's economic and social stability.

Alzheimer's disease (AD) is the most common form of dementia in the ageing population. This research project aims to identify and characterise new genes involved in the copper regulation of the Alzheimer's disease gene. This may lead to the development of novel therapeutic targets and clinical intervention strategies as well as early diagnostic procedures in preventative healthcare for the treatment of AD. The benefits would affect the international community as a whole, potentially minimising the socio-economic costs arising from the predicted world-wide increase in AD in the ageing population.Read moreRead less

This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiatives in developmental and cellular biology. This large-scale, high-resolution expression profiling infrastructure is required to maintain international competitiveness and will dramatically improve our gene discovery, functional assessment and understanding of vertebrate development.Read moreRead less
Developmental Switches: Nuclear Transport and Spermatogenesis. We propose to test the novel hypothesis that changes in the nuclear import machinery are a key facet of cellular differentiation. We will investigate a new paradigm in developmental biology regarding whether differentiation is achieved, or can be directed, by altering transport of macromolecules, such as specific transcription factors, into the nucleus. This project will define changes in the nuclear import machinery that accomp ....Developmental Switches: Nuclear Transport and Spermatogenesis. We propose to test the novel hypothesis that changes in the nuclear import machinery are a key facet of cellular differentiation. We will investigate a new paradigm in developmental biology regarding whether differentiation is achieved, or can be directed, by altering transport of macromolecules, such as specific transcription factors, into the nucleus. This project will define changes in the nuclear import machinery that accompany germ and somatic cell differentiation in the developing and adult mammalian testis. This will be linked to changes in the function of key proteins acting within the nucleus using both in vitro and in vivo approaches.

Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity ....Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity, insulin resistance and various forms of cancers is well established) are leading to a rapid increase in new cancer cases, thus driving a rapid increase in demand for better treatments. This is particularly relevant in Indigenous health where obesity is on the rise following the transition from a traditional to an urban lifestyle.Read moreRead less

Our studies will, for the first time, combine two complementary cutting-edge approaches, protein identification by proteomic analysis, and mRNA profiling by microarray analysis, to define these pathways and develop a comprehensive catalogue of proteins and gene expression patterns during cartilage development and bone formation. This information will provide insight into the regulation of cartilage differentiation, maturation and structure, and will provide a critical platform for the development of more sophisticated cartilage and bone biomaterials for improved tissue repair and regeneration.Read moreRead less

Our team has recently developed novel recruitment models and a new and innovative method of isolating primordial follicles which will enable us to identify the role of c-kit and selected TGF beta family members in recruitment. This work will provide cornerstone scientific knowledge about the control of female reproduction and provide the impetus for the development of more effective contraception and superovulation strategies in mammals.Read moreRead less

Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the most fundamental questions in the whole of biology: what is the basis for the primal distinction between sex and soma?Read moreRead less
