Proteomic and genetic analysis of subfertile bull spermatozoa. This project aims to identify protein changes on spermatozoa that are highly correlated with the fertility status of bulls. Bull fertility has approached an all-time low as breeding practice has focused predominately on milk production and beef tenderness. This project aims to understand the genetic causes that underpin bull and cattle infertility, and investigate better methods to predict the fertility status of bulls. This project ....Proteomic and genetic analysis of subfertile bull spermatozoa. This project aims to identify protein changes on spermatozoa that are highly correlated with the fertility status of bulls. Bull fertility has approached an all-time low as breeding practice has focused predominately on milk production and beef tenderness. This project aims to understand the genetic causes that underpin bull and cattle infertility, and investigate better methods to predict the fertility status of bulls. This project expects to contribute to better clinical management of cattle. This information can then be used for the development of a better diagnostic assay for both the dairy and beef industry.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
Identification of causal variants for complex traits. The aim of this project is to identify causal variants for complex traits in cattle and humans. Although most important traits in agriculture, medicine and evolution are complex traits, very few of the genetic variants affecting these traits are known and this undermines our understanding of how genetic variants affect a trait and practical uses of this knowledge. Huge datasets of individuals with genome sequence and phenotypes and new statis ....Identification of causal variants for complex traits. The aim of this project is to identify causal variants for complex traits in cattle and humans. Although most important traits in agriculture, medicine and evolution are complex traits, very few of the genetic variants affecting these traits are known and this undermines our understanding of how genetic variants affect a trait and practical uses of this knowledge. Huge datasets of individuals with genome sequence and phenotypes and new statistical methods provide the opportunity to close this gap. The outcome will be identification of many genomic variants causing variation in complex traits. This will benefit scientific understanding of complex traits and the ability to predict traits for individuals from their genome sequence.Read moreRead less
Mouse models for the identification of factors involved in muscle adaptation. The ability of muscle to adapt to meet functional demands is essential for mobility in normal daily life, in ageing well, in individuals with muscle diseases and nerve damage and in athletes. The ability of muscle to change its cellular composition is desirable for the livestock industry. Knowledge of how genes in muscle cells are regulated to adapt to demands has significant implications for public health and economic ....Mouse models for the identification of factors involved in muscle adaptation. The ability of muscle to adapt to meet functional demands is essential for mobility in normal daily life, in ageing well, in individuals with muscle diseases and nerve damage and in athletes. The ability of muscle to change its cellular composition is desirable for the livestock industry. Knowledge of how genes in muscle cells are regulated to adapt to demands has significant implications for public health and economic benefits. We have devised model systems that will allow us to identify the regulators of these genes in order to develop therapies to combat these changes in ageing and damaged muscle, to improve the quality of meat and optimise sport performance.Read moreRead less
Evolution, selection and estimation of polygenic epistatic networks in quantitative traits. Traits observed in organisms, such as height, are the result of an individual's genes and how they relate to the environment. But genes do not act alone; they work together in complex interactions. This project aims to understand these interactions and their role in animal production and human disease.
Cracking the code of snails to elucidate parasite disease transmission. In Australia, a disease caused by liver flukes causes major economic losses to livestock production. The role of Australian pond snails as intermediate hosts for this parasite is poorly understood. This project aims to explore the phylogeography, biology and genomics of these snails. It expects to create novel molecular resources for important snail species and verify their roles as key vectors of flatworm parasites. The cur ....Cracking the code of snails to elucidate parasite disease transmission. In Australia, a disease caused by liver flukes causes major economic losses to livestock production. The role of Australian pond snails as intermediate hosts for this parasite is poorly understood. This project aims to explore the phylogeography, biology and genomics of these snails. It expects to create novel molecular resources for important snail species and verify their roles as key vectors of flatworm parasites. The curation of genomic and transcriptomic data sets, and elucidation of snail–parasite interactions will underpin the development of environmental diagnostic tests and deliver a new generation of intervention strategies to reduce the burden of liver fluke disease through the control of their snail intermediate hosts.Read moreRead less
