The current proposal will explore new venues in adult neural stem cell research and contribute to the further development of molecular biology and neuroscience research in Western Australia and Australia. The use of neural stem cells holds therapeutic promise for the treatment of a wide variety of neurological conditions, including neurotrauma and stroke. The proposed research will provide new data on the fundamental cellular and molecular events that are required to trigger the birth, differentiation and conditions for growth of new neurons in the adult nervous system. The generation of such insights will be critical for any translational research.

Dissecting a hematopietic transcription factor complex. The development of mature active cells is a highly complex and coordinated process that is controlled largely by groups of interacting regulatory proteins. We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interaction ....Dissecting a hematopietic transcription factor complex.

We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interactions and be used as lead compounds for treatments for disease.Read moreRead less
The Shape of Plants; Discovering factors that control morphology by organizing the cytoskeleton. Understanding how plants generate the huge diversity of shapes seen in nature is both a scientific challenge and a biotechnological opportunity. Microtubules dominate cell architecture, providing dynamic, yet rigid, frameworks for defining or changing growth polarity. We recently discovered and cloned MOR1, a gene that is essential for organizing microtubules and controlling morphogenesis. This place ....The Shape of Plants; Discovering factors that control morphology by organizing the cytoskeleton. Understanding how plants generate the huge diversity of shapes seen in nature is both a scientific challenge and a biotechnological opportunity. Microtubules dominate cell architecture, providing dynamic, yet rigid, frameworks for defining or changing growth polarity. We recently discovered and cloned MOR1, a gene that is essential for organizing microtubules and controlling morphogenesis. This places us in a strong position to resolve a long-standing mystery: how are microtubules organized? We intend to define MOR1's structural attributes, identify its interacting proteins and innovate an ambitious screen for additional genes that have related functions. This project should stimulate new ideas and applications.Read moreRead less
Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces. Cord blood cells obtained at the time of delivery of a baby are a valuable resource that have the potential to develop into many cell types. This Project entails attaching stem cells derived from cord blood to appropriate 3 dimensional smart surfaces, and examining the ability of such cells to develop into insulin-producing cells. An understanding of how to coax stem cells, seeded on to smart surfaces, to develop into ma ....Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces. Cord blood cells obtained at the time of delivery of a baby are a valuable resource that have the potential to develop into many cell types. This Project entails attaching stem cells derived from cord blood to appropriate 3 dimensional smart surfaces, and examining the ability of such cells to develop into insulin-producing cells. An understanding of how to coax stem cells, seeded on to smart surfaces, to develop into mature cells with different functions will enhance our ability to understand how cells develop. As well, it enhance the potential usefulness of cord blood for research purposes. Read moreRead less
An X-ray crystallographic investigation into co-receptors on T-lymphocytes. T lymphocytes are an indispensable cellular component of the immune system. The normal process of T cell selection in the thymus, and the ability of mature T cells to respond to foreign antigens are governed by receptor recognition and co-receptor mediated events. The co-receptors encompass a wide spectrum of structurally diverse proteins that are involved in adhesion, co-ligation and signal transduction. This proposa ....An X-ray crystallographic investigation into co-receptors on T-lymphocytes. T lymphocytes are an indispensable cellular component of the immune system.

The co-receptors encompass a wide spectrum of structurally diverse proteins that are involved in adhesion, co-ligation and signal transduction. This proposal aims to investigate, using X-ray crystallography as the primary research tool, co- receptors located on T-lymphocytes. This work will gain fundamental insights into co-receptor function.Read moreRead less
Myofibroblast differentiation: from haemopoietic cells to smooth muscle. Until very recently the ability of adult cells with specific differentiated functions to re-differentiate for another function was thought to be extremely limited. However we have shown that cells ultimately derived from the bone marrow can differentiate into fibroblasts, then into myofibroblasts and then into smooth muscle cells. This project will build on these unique findings and determine the molecular mechanisms cont ....Myofibroblast differentiation: from haemopoietic cells to smooth muscle. Until very recently the ability of adult cells with specific differentiated functions to re-differentiate for another function was thought to be extremely limited. However we have shown that cells ultimately derived from the bone marrow can differentiate into fibroblasts, then into myofibroblasts and then into smooth muscle cells. This project will build on these unique findings and determine the molecular mechanisms controlling this process. We hypothesise that the local environment of a cell is critical and will involve a combination of particular extracellular matrix and growth factors as well as mechanical tension and the presence of other cell types.Read moreRead less
CesA (cellulose synthase) genes of Arabidopsis; all doing the same job or specialists cooperating to make the most abundant biopolymer. The biosphere makes more cellulose than any other polymer with fibre industries depending on its physical properties and atmospheric carbon dioxide levels depending on its stability as a carbon sink. Demonstrations that cellulose production needs CesA genes drove recent progress in elucidating the mechanism of synthesis. CesA proteins all look very similar but i ....CesA (cellulose synthase) genes of Arabidopsis; all doing the same job or specialists cooperating to make the most abundant biopolymer. The biosphere makes more cellulose than any other polymer with fibre industries depending on its physical properties and atmospheric carbon dioxide levels depending on its stability as a carbon sink. Demonstrations that cellulose production needs CesA genes drove recent progress in elucidating the mechanism of synthesis. CesA proteins all look very similar but if all do the same job, why do plants need so many and why do none seem redundant? We will make gene interchanges in transgenic plants, build chimeric genes and identify where each CesA protein operates. This will identify their individual and cooperative contributions to cellulose production.Read moreRead less

The outcomes of this project will increase the understanding of how nerve cells develop and regenerate after injury. The research outcomes and the development of new innovative methodologies as part of the project will be of high significance for the neuroscience research community both within Australia and overseas. The findings will also pave the way for the development of novel therapies that promote neuronal regeneration relevant for disorders such as spinal cord injury and Alzheimer's disease, which constitute a large socio-economic burden in Australia. Currently, 400 people contract spinal cord injury every year, corresponding to an annual cost of $1 billion, and more than 500 000 aging people suffer from Alzheimer's disease.Read moreRead less
