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
Breeding for the future - Alpaca genetics. The Australian alpaca industry is recognised as an international leader. Alpaca fleece provides an annual national economic benefit of $1 million and has enormous potential for growth. This project will use a novel molecular mapping approach to generate a genetic test for desirable Suri fleece - the single biggest factor in developing a purebreeding suri line whilst retaining variation in other traits and avoiding inbreeding. This will quickly increase ....Breeding for the future - Alpaca genetics. The Australian alpaca industry is recognised as an international leader. Alpaca fleece provides an annual national economic benefit of $1 million and has enormous potential for growth. This project will use a novel molecular mapping approach to generate a genetic test for desirable Suri fleece - the single biggest factor in developing a purebreeding suri line whilst retaining variation in other traits and avoiding inbreeding. This will quickly increase the industry value, providing opportunity for rural communities to diversify farming enterprises and maximise income, and offering further employment in regional areas. This project will ensure Australian breeders retain a competitive edge in the face of alpaca research beginning in the USA. Read moreRead less
Investigating a new way in which diet impacts animal biology. This project aims to investigate the importance of a new way in which diet can alter animal biology. High fat or high sugar diets increase the binding of products of metabolism to chromosomes, which can completely alter the way that DNA is packaged and read. This project will use cell culture, rodent and fly models to identify the regions of the genome that are most affected by the new process. The project will also determine whether ....Investigating a new way in which diet impacts animal biology. This project aims to investigate the importance of a new way in which diet can alter animal biology. High fat or high sugar diets increase the binding of products of metabolism to chromosomes, which can completely alter the way that DNA is packaged and read. This project will use cell culture, rodent and fly models to identify the regions of the genome that are most affected by the new process. The project will also determine whether the cell is harmed, or in fact harnesses the process to control development or metabolism. This project has implications for our understanding of the ways in which genes interact with the environment especially in times of change.Read moreRead less
