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
Epigenetic and neurobehavioural changes in a new mouse model of foetal alcohol spectrum disorders. Foetal alcohol syndrome involves changes in growth, skull structure, central nervous system defects and intellectual disabilities. This project will use a mouse model to study the underlying causes of this disorder, focussing on brain structure and function, and aim to identify markers that can be used for early diagnosis and treatment.

North Queensland is a fast growing region with significant need for the development of a world-class research facility. James Cook University has recently established the Comparative Genomics Centre at the School of Pharmacy and Molecular Sciences, which will contribute to education and basic research in the region. The research outcomes from the projects of the Comparative Genomics Centre and affiliated laboratories facilitated by the analytical flow cytometer will support the definition and identification of the interactions between genetic and environmental factors in disease and will help to attract researchers. Results from this work will aid the search for therapies for specific health problems.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
A shared genetic basis for development of the nervous system and glands. Fruit flies possess strikingly similar versions of the genes that promote normal human development. The list of systems with genetic parallels between humans and fruit flies includes the respiratory and circulatory systems; cardiovascular development and disease; sleep; learning and memory; brain development and disease; taste, sight, smell and hearing. This project could add at least some human glands, the mucous-secreting ....A shared genetic basis for development of the nervous system and glands. Fruit flies possess strikingly similar versions of the genes that promote normal human development. The list of systems with genetic parallels between humans and fruit flies includes the respiratory and circulatory systems; cardiovascular development and disease; sleep; learning and memory; brain development and disease; taste, sight, smell and hearing. This project could add at least some human glands, the mucous-secreting goblet cells, to this list, providing a potentially useful model for studying human diseases associated with gland dysfunction.

Deciphering genome function in animal development. The normal development of an embryo depends on complex and finely tuned gene regulatory mechanisms. In this Fellowship, I will use sophisticated new technologies to discover which of our 30,000 genes is important for embryonic development, reveal the roles of these genes, and identify the control mechanisms that can go awry to cause birth defects. Our research will suggest new ways to diagnose and deal with these conditions, and will be applicab ....Deciphering genome function in animal development.

Our research will suggest new ways to diagnose and deal with these conditions, and will be applicable to stem cell technologies, tissue regeneration, cancer biology, conservation, pest management and livestock breeding, thus delivering significant economic and social benefits to Australia.

Perceptual suppression mechanisms in the Drosophila brain. This project will investigate common processes underlying three means to losing conscious perception: selective attention, sleep and general anaesthesia. By studying these suppression mechanisms in a genetic model, the fly Drosophila melanogaster, fundamental processes will be highlighted that are required in the brain for maintaining perception in general.
The role of RNA editing by the brain-specific enzym ADAR3 in learning and memory. Higher-order cognition sets us apart from other species but how this is achieved is still under debate. The project will test the idea, strongly supported by recent genomic analyses, that subtle changes in the sequences of RNA in response to environmental stimuli underpin this extraordinary ability.
Investigating differences in decision-making ability in older adults. This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understan ....Investigating differences in decision-making ability in older adults. This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understanding of how decision-making evolves in healthy ageing, and a tool based on genetic scores and computational modelling to predict an individual's trajectory of cognitive function. This could help identify individuals who are at risk for cognitive decline, which could then inform better interventions.Read moreRead less
The function of menin in mammalian development. This project aims to determine the role of a ubiquitous transcriptional co-regulator, menin, in mammalian development. Mice that lack menin through targeted deletion of the gene die during embryogenesis, but the cause is unknown, although is likely to be due to the abnormal expression of genes usually regulated by this factor. We will determine which genes are inappropriately expressed and responsible for the accompanying developmental defects. Thi ....The function of menin in mammalian development.
