The role of epigenetics in the early gestational programming of adult phenotype by ethanol. The concept of foetal programming is changing the way we think about the aetiology of complex disease in adults. Our studies would emphasise that adverse events during pregnancy can have long-term health implications, with concomitant social and economic consequences. In America, the prevalence of foetal alcohol syndrome is comparable with rates for Down syndrome. The Aboriginal community in Australia ....The role of epigenetics in the early gestational programming of adult phenotype by ethanol. The concept of foetal programming is changing the way we think about the aetiology of complex disease in adults. Our studies would emphasise that adverse events during pregnancy can have long-term health implications, with concomitant social and economic consequences. In America, the prevalence of foetal alcohol syndrome is comparable with rates for Down syndrome. The Aboriginal community in Australia has been identified as a high-risk group. The knowledge gained from this project could aid in the development of screening strategies to predict the likelihood of disease developing later in life, providing an opportunity for presymptomatic healthcare.Read moreRead less
CENTRE for INTEGRATIVE LEGUME RESEARCH. Legumes are essential for environmental sustainability and are important for maintaining human health. The Centre combines innovative genomic approaches to investigate the causal phenotypic links required for regulation of legume growth. The unique coexistence of multiple pluripotent meristems in shoots, roots, flowers and nodules permits the discovery of new paradigms governing legume architecture, reproductive differentiation and root-nodule developmen ....CENTRE for INTEGRATIVE LEGUME RESEARCH. Legumes are essential for environmental sustainability and are important for maintaining human health. The Centre combines innovative genomic approaches to investigate the causal phenotypic links required for regulation of legume growth. The unique coexistence of multiple pluripotent meristems in shoots, roots, flowers and nodules permits the discovery of new paradigms governing legume architecture, reproductive differentiation and root-nodule development. New knowledge of the plant growth processes through mechanistic analysis of organ induction provides the tools to optimise the legume's productivity, quality, and environment adaptation.Read moreRead less
Does developmental noise have an epigenetic basis? One's ultimate phenotype is the result of a combination of genotype and environment, and includes a poorly understood component termed ?developmental noise?. The molecular basis of developmental noise remains unknown, but it appears to be established in early development and to be retained for the life of the organism. We propose that the molecular basis of developmental noise is the epigenetic state of the genome. The stochastic nature of th ....Does developmental noise have an epigenetic basis? One's ultimate phenotype is the result of a combination of genotype and environment, and includes a poorly understood component termed ?developmental noise?. The molecular basis of developmental noise remains unknown, but it appears to be established in early development and to be retained for the life of the organism. We propose that the molecular basis of developmental noise is the epigenetic state of the genome. The stochastic nature of the establishment of epigenetic state, combined with its heritability during mitosis, provides all the essential components for developmental noise. If our hypothesis proves correct, our work will have a major impact on the understanding of one of the most basic concepts in genetics.Read moreRead less
Molecular characterization of the role of menin in embryonic development. Menin is a protein that is necessary to prevent development of tumours. Deletion of menin in mice causes embryonic death. We think this is because menin is necessary in the placenta. This project will examine the role of menin in the fetus and the placenta, and provide information about how normal pregnancy and fetal growth is controlled.
ARC Centre of Excellence in Biotechnology and Development. The Centre will create a multidisciplinary research team focusing on the molecular mechanisms that drive the specification and differentiation of male germ cells. This research will improve our fundamental understanding of how complex regulatory networks control the expression of a complex phenotype, the spermatozoon. It will also create a platform of knowledge from which we can stimulate the growth of the Australian Biotechnology indust ....ARC Centre of Excellence in Biotechnology and Development. The Centre will create a multidisciplinary research team focusing on the molecular mechanisms that drive the specification and differentiation of male germ cells. This research will improve our fundamental understanding of how complex regulatory networks control the expression of a complex phenotype, the spermatozoon. It will also create a platform of knowledge from which we can stimulate the growth of the Australian Biotechnology industry, the protection of the Australian Environment and the well-being of the Australian people. Key issues for this Centre include testicular cancer, male infertility, contraception, pest animal control, environmental impacts on human health and gene pharming.Read moreRead less
Actin cytoskeleton regulation by E-cadherin and Src. This project examines a fundamental, novel mechanism of how cells work together in tissues. It will provide important new knowledge about how tissues become organized in health, and how organization might be disturbed in disease. It will build Australia's skill base in cutting-edge scientific research, and promote knowledge directed to the research priority area of Promoting and Maintaining Good Health.
How the Y Chromosome makes a male: Molecular genetic analysis of key sex-determining genes. Sex reversal and intersex syndromes are among the most common and highly stigmatized disorders affecting newborn babies. Our research will reveal how the Y chromosome regulates normal male development, identify the steps that go wrong in many male babies, and suggest ways to diagnose and deal with these conditions. It will also pave the way for biotechnological applications in the areas of stem cell techn ....How the Y Chromosome makes a male: Molecular genetic analysis of key sex-determining genes.

MOLECULAR GENETICS OF MAMMALIAN SEXUAL DEVELOPMENT: Molecular roles of SRY and SOX9. The development of sexual characteristics is critical to the survival of almost all animal species. This project seeks to clarify how male and female embryos develop differently, focusing on the Y-chromosome maleness gene Sry, and a closely related and equally important gene Sox9. We will study how these genes are switched on in developing gonads and how they interact with other genes to bring about testis forma ....MOLECULAR GENETICS OF MAMMALIAN SEXUAL DEVELOPMENT: Molecular roles of SRY and SOX9. The development of sexual characteristics is critical to the survival of almost all animal species. This project seeks to clarify how male and female embryos develop differently, focusing on the Y-chromosome maleness gene Sry, and a closely related and equally important gene Sox9. We will study how these genes are switched on in developing gonads and how they interact with other genes to bring about testis formation in male embryos. In this way we will discover new genes and mechanisms that are important for sexual identity and also other aspects of embryo development.Read moreRead less
