An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and ....An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and intervention strategies. Our work may suggest intervention strategies - such as supplementation of at-risk mothers with key molecules such as methyl donors - during foetal and early postnatal life, which could be key to preventing premature morbidity and mortality.Read moreRead less
Regulation of principal components of the antioxidant system in table grapes. 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 stres ....Regulation of principal components of the antioxidant system in table grapes. 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
Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to p ....Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to produce the phenotype by defining the critical period and systematically identifying genes that are expressed during this period. The effect of manipulating maternal dietary omega-3 PUFA and the role of angiotensin will then be examined. The project will discover how genetic, hormonal and environmental factors interact during the perinatal period of life to program food intake and body weight in adult life. Read moreRead less

A powerful new genetic view of the recent evolutionary history of humans and their diseases. Bacteria on teeth cause dental disease, but have also recently been associated with broader health issues, including diabetes, stroke and heart issues. In this project ancient DNA will be used to reveal changes in these bacteria as humans moved from a hunter-gatherer to farming lifestyle, providing valuable background information for modern dental/medical practice.
History, transport, or temperature: solving the riddle of Australia's temperate marine biodiversity. Maintaining a healthy and biologically diverse marine environment is essential for sustaining economic development. This project will integrate different research fields to answer fundamental questions about marine biodiversity. This will improve the capacity to identify priorities for conservation planning and sustainable use of Australia's marine assets.
Echoes of the earliest Homo sapiens movement out of Africa. The "Out of Africa" and "Multiregional Evolution" theories have proposed sharply different accounts for the origins of our species Homo sapiens. These have converged on opposite readings of the Australian human fossil record. Recent perspectives resulting from research on Pleistocene Australian mitochondrial DNA, and by osteologists on early Homo sapiens remains in Africa and Israel, hint at a chapter, as yet unwritten, in our species' ....Echoes of the earliest Homo sapiens movement out of Africa. The "Out of Africa" and "Multiregional Evolution" theories have proposed sharply different accounts for the origins of our species Homo sapiens. These have converged on opposite readings of the Australian human fossil record. Recent perspectives resulting from research on Pleistocene Australian mitochondrial DNA, and by osteologists on early Homo sapiens remains in Africa and Israel, hint at a chapter, as yet unwritten, in our species' Late Pleistocene dispersal from Africa. This project's collaborative research on fossils from Sri Lanka and Australasia will explore and test the implications for the colonisation history of the Indian Ocean region.Read moreRead less
