Summary
Neurodegenerative diseases result from the loss, damage or dysfunction of neural populations. For example, dopaminergic neurons are lost progressively in Parkinson's Disease. A potential method of treatment is 'cell therapy' which envisages transplantation of cells back to the site of cell loss, and restoration of function. Application of the cell therapy approach is limited by the unavailability of cells for transplantation. Embryonic stem (ES) cells provide a potential solution to this problem ....Neurodegenerative diseases result from the loss, damage or dysfunction of neural populations. For example, dopaminergic neurons are lost progressively in Parkinson's Disease. A potential method of treatment is 'cell therapy' which envisages transplantation of cells back to the site of cell loss, and restoration of function. Application of the cell therapy approach is limited by the unavailability of cells for transplantation. Embryonic stem (ES) cells provide a potential solution to this problem because they can be grown in unlimited numbers and differentiated to any kind of cell that is found in the embryo or adult. In this application we propose to continue our work on controlling the differentiation of ES cells to neural lineages. Production of dopaminergic neurons will be a particular focus. We will establish conditions that enable the production of these cells in a manner that is therapeutically relevant and predicted to be acceptable to regulatory authorities. Cells will be tested by transplantation into adult rats to assess their therapeutic potential, in particular persistence, integration and differentiation within the brain environment. Research required to achieve the production of transplantable cells will also provide basic information about the mechanisms by which the mammalian embryo allocates cells, specifically cells of the nervous system, to specific lineages during embryogenesis. This information will be important for the production of other neural cell types, which have therapeutic potential for treatment of diseases like stroke, motor neuron disease and spinal cord injury.Read moreRead less

Summary
Cancer is a complex disease that involves the mis-regulation of genes and aberrant cell-cell communication . To help gain a better understanding of these processes it is possible to examine simpler systems. This proposal uses a unique cancer model in flies to understand how a change in cell fate can endow cells with the ability to continue dividing and invading surrounding tissues, thus driving cancer development.
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. 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 interactions and be used as lead compounds for treatments for disease.Read moreRead less
Investigating the activator function of the Bim protein. Apoptosis is a research area where Australia has had long standing success. The first observations of this important process were made by Prof John Kerr in the 60's and 70's. A molecular renaissance developed in the late 80's and has led to the current explosion in this area of research. Many of these recent studies have been conducted at the Walter and Eliza Hall Institute.

Apoptosis is a research area where Australia has had long standing success. The first observations of this important process were made by Prof John Kerr in the 60's and 70's. A molecular renaissance developed in the late 80's and has led to the current explosion in this area of research. Many of these recent studies have been conducted at the Walter and Eliza Hall Institute. Our scientific endeavour is aimed at broadening the understanding of the mechanisms of cell death using genetically modified mouse models. Insights gained through this project will have far reaching implications for the design of new drugs to combat cancer and degenerative diseases.Read moreRead less
The role of the transcription factor Runx2 during mammary gland development and lactation. This proposal will further our understanding of mammary gland development and lactation and the mechanisms controlling mammary cell fate decisions such as differentiation. Regulation of cell fate lies at the core of most aspects of cell biology from normal development to dysfunction such as cancer. The knowledge gleamed from this project also has the potential to make economic gains for Australia by increa ....The role of the transcription factor Runx2 during mammary gland development and lactation. This proposal will further our understanding of mammary gland development and lactation and the mechanisms controlling mammary cell fate decisions such as differentiation. Regulation of cell fate lies at the core of most aspects of cell biology from normal development to dysfunction such as cancer. The knowledge gleamed from this project also has the potential to make economic gains for Australia by increasing the profitability and ensuring the sustainability of both the dairy and meat industries. Better understanding of the mechanisms controlling mammary epithelial cell differentiation should enable augmentation of lactation such as increasing milk protein content, using marker assisted selection (of targets such as Runx2) in cattle.Read moreRead less
Oxidative Damage and Cell Ageing. This research will benefit Australia by providing a fundamental understanding of how cells age. This will have immediate international impact at the scientific level and will inform strategies to reduce the rate of ageing and alleviation of age-related disorders. In the longer term the research may provide commercial and social outcomes by identifying antioxidant systems that will provide a genuine benefit in reducing ageing.
Cellular Responses to Oxidative Damage: Cell Aging. The aim of this project is to identify the mechanisms by which oxidative stress and free radical damage cause cell aging. This work will make a significant contribution to our understanding of the aging process in cells by identifying the major reactive oxygen species that contribute to cell aging, which defence systems and antioxidants provide the greatest degree of protection, what damage accumulates as cells age and which genetic systems ar ....Cellular Responses to Oxidative Damage: Cell Aging.
