The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less

The neuroethics of cognitive ageing. As the workforce ages, Australian and international governments are prioritising brain health, seeking to increase economic productivity and reduce the costs of age-related cognitive decline. In addition to healthy lifestyle habits, certain neurotechnologies are being promoted as the means to protect cognitive performance. This project aims to explore the ethical issues and social pressures that ageing individuals experience as a result of cognitive ageing. U ....The neuroethics of cognitive ageing. As the workforce ages, Australian and international governments are prioritising brain health, seeking to increase economic productivity and reduce the costs of age-related cognitive decline. In addition to healthy lifestyle habits, certain neurotechnologies are being promoted as the means to protect cognitive performance. This project aims to explore the ethical issues and social pressures that ageing individuals experience as a result of cognitive ageing. Understanding later life from the perspective of ageing individuals may enable society to meet the ethical and policy challenges raised by emphasising cognitive wellbeing above other aspects in the ageing process.Read moreRead less
The impact of Hyaluronic Acid on growth factor signalling and angiogenesis. Blood vessel development is controlled by growth factor signalling. Vessels are attracted by and migrate along growth factor gradients, and this is controlled by the extracellular matrix (ECM). From the zebrafish model, we have identified a novel gene that modulates the ECM, impacting growth factor signalling and vessel development. The project will explore by what mechanism this gene impacts signalling. It will comprehe ....The impact of Hyaluronic Acid on growth factor signalling and angiogenesis. Blood vessel development is controlled by growth factor signalling. Vessels are attracted by and migrate along growth factor gradients, and this is controlled by the extracellular matrix (ECM). From the zebrafish model, we have identified a novel gene that modulates the ECM, impacting growth factor signalling and vessel development. The project will explore by what mechanism this gene impacts signalling. It will comprehensively define where in the embryo it is required and investigate what cofactors it interacts with to perform its function. Using genetic zebrafish and mouse models as well as cell culture models we will investigate the fundamental biology of this gene.Read moreRead less
A new universal mechanism controlling body proportions in animals. This project aims to establish that a recently-discovered mechanism, the inhibitory cascade, determines the basic proportions of appendages and body segments in a diverse range of animal groups, particularly vertebrates and arthropods. The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade.

The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade. The project should benefit bioengineering by establishing control mechanisms for the manipulation and regeneration of teeth and limbs.Read moreRead less
How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understandi ....How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less
Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion o ....Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less
Upholding the right to cultural connection for children in care. A positive sense of cultural identity is critical to wellbeing, yet children in out-of-home care often lose their cultural identities and connections. There is little evidence to guide out-of-home care agencies to support a culturally meaningful foster care placement for non-Indigenous culturally and linguistically diverse children. This project tests promising practices identified by the partner organisations and research literatu ....Upholding the right to cultural connection for children in care. A positive sense of cultural identity is critical to wellbeing, yet children in out-of-home care often lose their cultural identities and connections. There is little evidence to guide out-of-home care agencies to support a culturally meaningful foster care placement for non-Indigenous culturally and linguistically diverse children. This project tests promising practices identified by the partner organisations and research literature to produce an exemplary model of cultural care, with input from children, carers and birth families. Trial implementation in the partner organisations will inform guidelines and recommendations so that the model can inform policy and practice in out-of-home care across Australia.
