Genetic analysis of cohesin function and regulation in Drosophila. In yeast, a multiprotein complex, called cohesin, holds newly replicated chromatids together until the cell is ready to partition each chromatid into its daughter cells. We and others have shown that cohesins are regulated differently in animal cells. We propose to combine classical genetic analyses with two new and innovative techniques, time-lapse confocal microscopy of fluorescent proteins in living cells and gene-specific kno ....Genetic analysis of cohesin function and regulation in Drosophila. In yeast, a multiprotein complex, called cohesin, holds newly replicated chromatids together until the cell is ready to partition each chromatid into its daughter cells. We and others have shown that cohesins are regulated differently in animal cells. We propose to combine classical genetic analyses with two new and innovative techniques, time-lapse confocal microscopy of fluorescent proteins in living cells and gene-specific knockout techniques to study key cohesin regulators in Drosophila. These studies will provide us with novel insights into how multicellular organisms regulate the structure and stability of their chromosomes.Read moreRead less

The proposed facility will represent world-leading technology in functional genomics and provide Australian scientists with unique opportunities to identify genes involved in a broad range of biological processes. This will contribute to fundamental knowledge in mammalian biology, and equally importantly, is likely to identify genes involved in important health problems such as cancer, inflammatory disease, brain damage and diabetes. Such genes may in turn constitute targets against which new therapies may be developed. This endeavour will contribute to national research priorities in both the health and scientific/technological development arenas.Read moreRead less
ARC/NHMRC Research Network in Genes and Environment in Development.

Interactions between the early environment and the genetic regulatory program of the developing organism have major consequences for the lifetime health of individuals. The primary objective of the Network in Genes and Environment in Development is to harness the resources of leading researchers from the currently distinct disciplines of developmental biology and developmental physiology to define key developmental regulatory networks and to address how environmental factors impinge on these regulatory networks. The formation of this National Research Network is unique, timely and strategic. It will generate new insights into the mechanisms by which events in early life determine the risk of adverse outcomes in perinatal and adult life.Read moreRead less
Understanding self-organising tissues. This project will discover how an organ can form from a mixture of component cells by 'self-organisation'. Understanding of how this can occur, could potentially be applied to the bioengineering of organs from component cells.
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

The project aims to investigate a mechanism of communication used by immune cells to guide each other towards sites of damage. The project will characterise newly revealed cell signalling membrane trails left behind by migrating cells, utilising biochemistry, innovative imaging and microscopy and a transparent zebrafish model to view cell migration through living tissues. Expected outcomes include new fundamental knowledge in the area of immune cell migration with relevance to the basic biology of inflammation, repair and regeneration and new innovations for cell imaging. Significant benefits are expected to arise from this new knowledge and from advanced skills training and improved national capabilities in bio-imaging and analysis.Read moreRead less
