Summary
Male fertility requires production of healthy sperm in the testis. This project builds on our discoveries that testicular cells regulate gene activity via the Snail family of proteins during sperm development, and that interruption of their activities reduces fertility in mice and fruitflies. Snail proteins are also active in cancer cells. We propose to study the precise steps in sperm production affected by Snail proteins and how they affect the progression of testicular cancer.
I seek the knowledge required to improve prevention, diagnosis and therapy for men with testicular pathologies by studying what controls early sperm development. My research will delineate how cellular signalling molecules lay the foundation for adult fertility, using animal studies, cell culture and clinical samples. Testis samples from testicular cancer patients will be used to test interventions that may kill tumour cells or offer a therapeutic option to men with impaired spermatogenesis.
Constructing an embryo. This project investigates the cellular and molecular mechanisms underlying temporal and spatial organisation in the eutherian preimplantation embryo. It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulat ....Constructing an embryo.

It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulations over the first 5 days of mouse pregnancy on embryonic temporal and spatial organisation.Read moreRead less
Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between mar ....Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between marsupials and other mammals. The focus on reproduction and development will also provide invaluable knowledge to underpin efforts to conserve our endangered species and to control those that are overabundant.Read moreRead less
Cellular signals controlling oocyte activation. This research will significantly advance our understanding of the basic biological processes that underpin the fertility rate of all mammals and are key to the immediate and future health and well-being of Australian landscape and society. Understanding the processes that maintain healthy quiescent oocytes over many years before activation and subsequent growth will enable development of methods of increasing productivity in domestic animals and en ....Cellular signals controlling oocyte activation. This research will significantly advance our understanding of the basic biological processes that underpin the fertility rate of all mammals and are key to the immediate and future health and well-being of Australian landscape and society. Understanding the processes that maintain healthy quiescent oocytes over many years before activation and subsequent growth will enable development of methods of increasing productivity in domestic animals and enhancing fertility in endangered species. Knowledge of these cellular mechanisms will underpin biotechnology platforms necessary for novel methods of feral animal population control thus contributing at multiple levels to an economically sustainable Australia.Read moreRead less
The control of meiosis in mammalian oocytes. This study will elucidate how the egg undergoes its final steps in preparation for fertilisation and early development. This will produce greater knowledge about how eggs develop, which may reveal new approaches to modulating reproductive capacity.
Male fertility requires sufficient production of healthy sperm in the testis. This project builds on our discovery that testicular cells communicate via the wnt family of proteins during sperm development, and that interruption of their activities reduces fertility in mice. We propose to use mouse models to study the precise steps in sperm production affected by Wnt signalling and how it works.
One in five Australian couples experience infertility and poor egg quality is a major contributing factor. Developing eggs in the ovary are surrounded by helper cells and we have discovered a new form of communication between these cells and the egg that regulates egg quality. This project will investigate the details of this dialogue and how it improves egg quality. New knowledge gained from this project will improve our understanding and treatment of infertility and reproductive diseases.
Mechanistic basis of a reproductive lesion in transforming growth factor beta-1 (TGFb1) null mutant mice. Null mutation in the gene encoding the cytokine transforming growth factor beta-1 (TGFb1) causes infertility in male and female mice. In recent experiments we have found that TGFb1 deficiency is associated with impaired ovarian and testicular steroidogenesis, arrested development of pre-implantation embryos and disrupted mammary gland morphogenesis. The aims of the current project are to un ....Mechanistic basis of a reproductive lesion in transforming growth factor beta-1 (TGFb1) null mutant mice. Null mutation in the gene encoding the cytokine transforming growth factor beta-1 (TGFb1) causes infertility in male and female mice. In recent experiments we have found that TGFb1 deficiency is associated with impaired ovarian and testicular steroidogenesis, arrested development of pre-implantation embryos and disrupted mammary gland morphogenesis. The aims of the current project are to unravel the mechanistic basis of the reproductive lesion in TGFb1 null mutant mice and to determine the effect of exogenous systemic delivery of TGFb1 in alleviating this lesion. It is expected that the project will provide new insight into key roles for TGFb1 in governing male and female fertility, and shed light on the prospects for exogenous supplementation of TGFb1 for improving reproductive performance in wild-type animals. This knowledge has potentially important applications in the livestock breeding industry, in devising novel contraceptive vaccine strategies, in the human pharmaceutical industry, and in devising novel contraceptive vaccine strategies.Read moreRead less
Extrinsic Control of Mammalian Germ Cell Delineation. Australia is a leader in the recent exciting breakthroughs in reproduction and development, such as cloning and embryonic stem cell propagation, and understanding how germ cells are specified would help us understand the biology underlying specification and developmental potential of all cells.

This research will continue to contribute to maintaining Australia's high reputation in advances in reproductive biology. In addition, a greater understanding of marsupial reproduction is a high priority for Australia in the 21st century, with its current unacceptably high rate of mammalian extinctions, for 'we cannot conserve until we comprehend' (Short, 1985).The results therefore are of great potential benefit to society.
