This established team of investigators will research into the molecular control of white blood cell formation and function, using a multidisciplinary, team approach to fundamental biological questions with a focus on potential clinical and commercial outcomes. The team will also attempt to identify new validated targets for therapeutic intervention by using both forward and reverse genetic approaches in mice coupled with complete phenotypic analyses of the blood cell system.
Examination of the Calcium Signalling Dynamics Linked to Integrin Adhesion Utilising a Novel Micro-imaging System. This study aims at increasing our understanding of the fundamental cell processes that allow cells to adhere to surfaces. The proposed study will lead to a greater understanding of the calcium signalling mechanisms that are fundamental to diverse biological phenomena such as, tissue regeneration and repair, blood clotting, cancer metastasis, and neuronal cell function. From a preven ....Examination of the Calcium Signalling Dynamics Linked to Integrin Adhesion Utilising a Novel Micro-imaging System. This study aims at increasing our understanding of the fundamental cell processes that allow cells to adhere to surfaces. The proposed study will lead to a greater understanding of the calcium signalling mechanisms that are fundamental to diverse biological phenomena such as, tissue regeneration and repair, blood clotting, cancer metastasis, and neuronal cell function. From a preventative health perspective, the investigation of platelet calcium signalling will greatly accelerate the development of new pharmaceuticals to tackle acute and chronic cardiovascular diseases, such as stroke, heart attack and artherosclerosis.

Function and regulation of the Schlafen gene family: novel regulators of blood cell proliferation and function. The immediate outcomes of the proposed research will be in fundamental knowledge and understanding of important cellular and biological processes in which the Schlafen genes are involved. In particular, Schlafen genes are likely to play a role in inflammatory responses and in blood cell growth. These process clearly have relevance to a range of major human (and animal) diseases includ ....Function and regulation of the Schlafen gene family: novel regulators of blood cell proliferation and function. The immediate outcomes of the proposed research will be in fundamental knowledge and understanding of important cellular and biological processes in which the Schlafen genes are involved. In particular, Schlafen genes are likely to play a role in inflammatory responses and in blood cell growth. These process clearly have relevance to a range of major human (and animal) diseases including infectious disease, auto-immune disease and leukaemia, and thus a long-term outcome may be improved treatments for such disease.

Summary
The development and maintenance of tissues in mammals are tightly controlled and complex processes involving the growth, maturation and survival of vast numbers of cells of various types. In cancer, the cell's capacity to faithfully regulate these processes is diminished or lost. Many of the proteins that are essential for growth control are produced by an important class of genes called proto-oncogenes; literally, the prototypes of cancer-causing genes. Naturally occurring mutations in these ge ....The development and maintenance of tissues in mammals are tightly controlled and complex processes involving the growth, maturation and survival of vast numbers of cells of various types. In cancer, the cell's capacity to faithfully regulate these processes is diminished or lost. Many of the proteins that are essential for growth control are produced by an important class of genes called proto-oncogenes; literally, the prototypes of cancer-causing genes. Naturally occurring mutations in these genes have been identified in man and are likely to play a major role in the initiation and progression of distinct human malignancies. A significant number of proto-oncogenes are enzymes called protein tyrosine kinases (PTKs). Research has shown that the function of PTKs is to relay growth signals or other regulatory signals from the outer surface of the cell to specific target proteins inside the cell. These target proteins are needed to relay the signal to other target molecules and so on. This highly ordered process, involving a specific sequence of proteins, ensures that cells respond appropriately to a given signal. Our research focuses on identifying and studying the immediate targets of PTKs with the broad aim of understanding how PTKs control growth in normal and cancerous cells. We have recently developed a method that has enabled us to identify a new protein that may regulate the growth of blood cells. The research proposed here aims to extend our preliminary observations showing that the growth of specific types of blood cells is inhibited by this protein. We also plan to search for new targets of a PTK that is involved in leukemia. The findings of this research will provide important insight into how blood cells are regulated in health and disease.Read moreRead less
Socs proteins in development and disease. Socs proteins are a component of a pathway that is central to a range of developmental processes, including embryonic development. In addition, there is evidence that these proteins are perturbed in several disorders. This Project will enhance our understanding of the Socs proteins and their role in disease, and ultimately provide an opportunity to identify new therapeutic strategies.
