An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus. Antioxidants are also involved in the plant's defences against abiotic and biotic stress. Here, the WA Table Grape industry has committed funds for an APAI to study regulation of antioxidants in relation to nutritional and postharvest qualities. Effects of preconditioning with mild oxidative stresses will be assayed, postharvest, using molecular and biochemical techniques.Read moreRead less
EPIGENETIC REPROGRAMMING OF MALIGNANT BREAST CANCER

Summary
Poorly differentiated breast cancers are aggressive tumors, frequently resistant to chemotherapy and associated with high morbidity. Herein we propose the engineering of more selective therapeutic agents able to target the genes involved in cancer initiation and resistance to treatment. We aim to correct and reprogram the cancer cell genome in state that is similar to normal, not tumorigenic cells. This work will generate novel forms of treatment for cancers that are presently not curable.
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand.

Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less

Summary
Blood vessels play an essential role in maintaining the supply of nutrients to every organ and tissue in the body. Improper development of blood vessels in the embryo can compromise survival of the embryo, and defects in the ability of blood vessels to grow, regenerate and adapt to change during adult life can be life-threatening. The growth of new blood vessels (angiogenesis) is also an important factor in the ability of solid tumours to grow during the progression of cancer. It is therefore of ....Blood vessels play an essential role in maintaining the supply of nutrients to every organ and tissue in the body. Improper development of blood vessels in the embryo can compromise survival of the embryo, and defects in the ability of blood vessels to grow, regenerate and adapt to change during adult life can be life-threatening. The growth of new blood vessels (angiogenesis) is also an important factor in the ability of solid tumours to grow during the progression of cancer. It is therefore of fundamental importance in the health sciences to gain an understanding of how blood vessels form and regenerate. As a result of our collaborative research efforts, we have discovered a gene, Sox18, that appears to regulate blood vessel development by controlling the formation and-or behaviour of endothelial cells, which line the blood vessels and make them impermeable. Our research so far indicates that MICE WITH DEFECTS IN SOX18 DIE FROM VASCULAR DEFECTS, underlining the importance of this gene. THIS PROJECT IS CONCERNED WITH FINDING OUT HOW SOX18 WORKS - exactly what goes wrong in mice lacking this gene, whether Sox18 can influence endothelial cell behaviour in cell culture, how Sox18 comes to be active in endothelial cells, what genes are switched on by Sox18, and what genes Sox18 co-operates with in its role in endothelial cells. The answers to these questions will not only provide fundamental basic information about how blood vessels development is controlled, but also sow the seeds for possible future therapies in which blood vessel development could be stimulated (eg in wound healing) or suppressed (eg in tumour progression) through pharmaceutical intervention.Read moreRead less

Faba beans are an important pulse crop in Australia. They are exported to the Middle East and Europe for human consumption where buff coloured beans are desired. A third of beans become discoloured in storage. These are downgraded to stock feed with a loss of $50 per ton to the grower. Currently little is known about the causes. Environmental factors and selected genotypes will be assessed to determine the potential causes of discoluration. Analytical techniques will ascertain the discolouration process and the compounds produced. The aim is to provide growers with information on management strategies and breeders of strain resistant genotypes.Read moreRead less

The production of red blood cells is primarily controlled by the hormone erythropoietin (Epo). The availability of this hormone in a recombinant form has aided in the treatment of numerous forms of anaemia resulting from kidney failure, malignancies, and AIDS. Previously we had identified that the protein Lyn must be present inside primitive red blood cells for Epo to stimulate them to become mature functional cells. Recently, we have demonstrated that mice lacking the Lyn gene develope major problems with their red blood cells. We have identified several molecules which interact with Lyn in red blood cells. We have shown that a molecule called Cbp is important for Epo function in individual red blood cells and now we plan to investigate its function in whole animals. We have shown that a new molecule called Arp is important for red blood cell development. This protein moves in and out of the nucleus (where DNA is stored) and may be important in the regulation of genes needed for red blood cells. The third gene (AFAPbeta) is also novel and is closely related to another called AFAP-110, which can exert effects on the structure of a cell. Since red blood cells have to shrink considerably during their development, the role of AFAPbeta on red blood cell structure will also be investigated. From these experiments we should develop a much better understanding of how the production of red blood cells is controlled and how diseases of red blood cells (such as anaemia) occur.Read moreRead less
