Summary
Our previous work has led to the identification of mutations underlying human birth defects. Similarly, our proposed work will identify a new gene as potentially mutated in human heart defects. We will determine its overlapping functions with a related gene and elucidate their roles in embryonic development and cancer.
I am a developmental biologist studying how transcription factors regulate developmental processes. I have a particular interest in the MYST family of co-activators, their role in regulating self-renewal and lineage determination in stem cells, their role in oncogenesis and targeting these proteins to develop new cancer therapeutics.
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.

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 technology, pest management, wildlife conservation and animal breeding.Read moreRead less
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.

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
Insect development : the role of cytochrome P450s. Pest insects vector human diseases such as malaria and impose a massive burden in agriculture due to control costs and production losses. The intelligent control of insect pests requires an understanding of their development that is controlled by hormones. This project will provide an in depth understanding of insect hormone synthesis/degradation that is controlled by a class of enzymes, the cytochrome P450s. This will increase the potential ....Insect development : the role of cytochrome P450s.

The intelligent control of insect pests requires an understanding of their development that is controlled by hormones. This project will provide an in depth understanding of insect hormone synthesis/degradation that is controlled by a class of enzymes, the cytochrome P450s. This will increase the potential for new insect-specific control strategies with a decreased environmental impact.Read moreRead less

Summary
Adaptation to air breathing at birth is dependent on the generation of normal lung structure. Failure of lung formation and surfactant function results in respiratory failure at birth. Although progress has been made in identifying genes and pathways critical for lung function, the factors that control their expression, so called epigenetic factors, are not known. In this proposal, we will seek to identify these factors controlling lung formation.
This proposal uses the zebra fish system, which it is uniquely suited to investigate the regulation of disease genes. In all of these diseases preliminary work has already been performed and screening assays have been developed in a previous project (ZF-MODELS). In addition, the project will investigate genetic abnormalities of the eye and visual processing, genetic pathways underlying tissue regeneration and repair, and homologs of human genes related to diabetes and obesity, as well as infecti ....This proposal uses the zebra fish system, which it is uniquely suited to investigate the regulation of disease genes. In all of these diseases preliminary work has already been performed and screening assays have been developed in a previous project (ZF-MODELS). In addition, the project will investigate genetic abnormalities of the eye and visual processing, genetic pathways underlying tissue regeneration and repair, and homologs of human genes related to diabetes and obesity, as well as infectious disease and cancer. The Australian component will perform a systematic characterisation of enhancer elements of potential disease genes. This characterisation will build on the concept of genomic regulatory blocks (GRBs) which contain highly conserved non-coding elements (HCNEs) acting as long-range enhancers of developmental genes (recently discovered by T. Becker in the ZF-MODELS project).Read moreRead less
