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
Elucidation of the signalling pathways during fertilization in mammals. This grant sets out to understand how the union of the sperm and egg at fertilization generates a viable embryo: this is a fundamental event in biology. We aim to understand the basic signalling pathways from the sperm which allow the egg to become an embryo and are known to influence embryo quality. They are therefore important in our understanding of what constitutes a healthy early start to life. Australia also has econom ....Elucidation of the signalling pathways during fertilization in mammals.

We aim to understand the basic signalling pathways from the sperm which allow the egg to become an embryo and are known to influence embryo quality. They are therefore important in our understanding of what constitutes a healthy early start to life. Australia also has economic interests in understanding the reproductive process in aiding breeding programs for commercially important livestock and endangered species and contraception programs for pest populations.

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

Summary
Confocal Laser Scanning Microscopy for Live Cell Imaging. The University of Newcastle has invested heavily in its biological and life sciences to create a research nexus focusing on national research priorities in biotechnology and environmental protection. The Live Cell Imaging platform will be utilized by scientists researching such strategically important areas including developmental biology, intracellular signalling cascades, cell cycle dynamics, plant development and microbiology. Moreover ....Confocal Laser Scanning Microscopy for Live Cell Imaging. The University of Newcastle has invested heavily in its biological and life sciences to create a research nexus focusing on national research priorities in biotechnology and environmental protection. The Live Cell Imaging platform will be utilized by scientists researching such strategically important areas including developmental biology, intracellular signalling cascades, cell cycle dynamics, plant development and microbiology. Moreover, this component of the University's research portfolio plays a major role in the postgraduate training of young Australian scientists who will, in turn, fuel future developments in both the life sciences and biotechnology industries.Read moreRead less
Steroidal control of male meiosis. This innovative project will study a complex cellular process (meiosis) essential for sperm development and sexual reproduction. Collaborations and novel experimental design provide cutting edge techniques and opportunity for Australian researchers to contribute important discoveries to this field. We aim to provide new knowledge of steroid-dependent molecular factors that may activate (or inhibit) meiosis. Such novel information may significantly impact divers ....Steroidal control of male meiosis. This innovative project will study a complex cellular process (meiosis) essential for sperm development and sexual reproduction. Collaborations and novel experimental design provide cutting edge techniques and opportunity for Australian researchers to contribute important discoveries to this field. We aim to provide new knowledge of steroid-dependent molecular factors that may activate (or inhibit) meiosis. Such novel information may significantly impact diverse areas related to controlling mammalian reproductive development, such as health and well-being (a healthy start to life, fertility control), farming and agriculture (livestock production, pest management) and the Australian environment (conservation, pest management).Read moreRead less
