Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to ....Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to provide novel functions, thereby facilitating the evolution of specific characteristics within species.Read moreRead less
Discovering mechanisms of primary embryonic tissue migration through live cell imaging and novel genetic approaches. The studies proposed here will provide concepts and knowledge about the molecular basis of cell migration that will impact on diverse aspects of human health, such as the causes and nature of tumour metastasis and our understanding of the developmental basis of birth defects. In addition, understanding cell migration mechanisms will allow us to better predict or control the behav ....Discovering mechanisms of primary embryonic tissue migration through live cell imaging and novel genetic approaches.

In addition, understanding cell migration mechanisms will allow us to better predict or control the behaviour of therapeutic stem cells introduced into the body.Read moreRead less
The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster. To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its ....The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster. To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its phenotype. By studying the effects of Cyp genes on fly survival, Cyp gene expression and regulation, and expressing selected Cyp genes in a yeast expression system, we will enhance our understanding of Cyp gene function and evolution.Read moreRead less
Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce ....Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce knowledge of broad relevance to modern life sciences and its applications in medicine and biotechnology. Finally, a better understanding of yeast cellular biology is of benefit to the food and biotechnology sector of industry.Read moreRead less
ARC Centre of Excellence in Biotechnology and Development. The Centre will create a multidisciplinary research team focusing on the molecular mechanisms that drive the specification and differentiation of male germ cells. This research will improve our fundamental understanding of how complex regulatory networks control the expression of a complex phenotype, the spermatozoon. It will also create a platform of knowledge from which we can stimulate the growth of the Australian Biotechnology indust ....ARC Centre of Excellence in Biotechnology and Development. The Centre will create a multidisciplinary research team focusing on the molecular mechanisms that drive the specification and differentiation of male germ cells. This research will improve our fundamental understanding of how complex regulatory networks control the expression of a complex phenotype, the spermatozoon. It will also create a platform of knowledge from which we can stimulate the growth of the Australian Biotechnology industry, the protection of the Australian Environment and the well-being of the Australian people. Key issues for this Centre include testicular cancer, male infertility, contraception, pest animal control, environmental impacts on human health and gene pharming.Read moreRead less
