Maximizing male fertility: the role of CRISP proteins. This project aims to investigate the function of cysteine rich secretory protein (CRISP) family members in fertility. It is expected to generate new knowledge on the role CRISP1 and 4 play in sperm competition in vivo, and thus, evolutionary processes; to define the role seminal plasma CRISPs play in fertility; and identify the mechanism underpinning their biological activities. This will be achieved using a range of innovative, state-of-the ....Maximizing male fertility: the role of CRISP proteins.

Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human.

The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less

This project aims to identify biomarkers of stallion fertility and early pregnancy in thoroughbred and Standardbred horses using biochemistry, proteomics and ribonucleic acid analyses. Responding to industry calls for improved methods of detecting and managing infertility in both stallions and mares, this project will connect Australian horse breeders and international clinical experts with the world renowned reproductive Priority Research Centre with the intended outcome of novel reproductive technologies and diagnostic tests. This should both secure international competitiveness and significantly enhance profitability and employment in this culturally significant industry.Read moreRead less
Targeting TGF-beta proteins to control animal reproduction. This project aims to develop a suite of novel biologics to control fertility in female mammals. This project expects to demonstrate that targeting a single class of ovarian proteins will enhance or inhibit egg production. The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide ....Targeting TGF-beta proteins to control animal reproduction.

The expected outcomes of this project are to (1) transform the breeding of livestock animals, which should provide significant benefits to the agricultural industry, through increased herd/flock sizes, and (2) provide a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

This project aims to enhance our understanding of gonadal sex determination (testis versus ovary development), using innovative genetic approaches that exploit the avian embryo as a model system. The project aims to define the key molecular events regulating gonadal sex determination in birds. It intends to enhance knowledge in the area of cell biology, embryology, and sex determination specifically. Importantly, it will have application to the poultry industry. Currently, half of all hatchlings (the undesired sex) are culled. The proposed project intends to illuminate those genetic pathways that can be targeted to produce single-sex lines of birds, a major goal of the multi-billion dollar Australian and global poultry industries.Read moreRead less

Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.

Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This knowledge will reveal how IPO5 controls formation of sperm by revealing what other proteins it binds to and how this affects cell signaling and responses to the environment.
Benefits: This will provide information about potential interventions to control fertility or to repair abnormal cells.

Ancestral, conserved and novel mechanisms in marsupial genomic imprinting. Genomic imprinting is the differential expression pattern of some genes depending on whether the gene copy came from the mother or the father. This differential expression is essential for embryonic development and errors lead to disease. To date, most of our knowledge of the control of genomic imprinting comes from the mouse, but much less is known about this process in marsupials. Our comparative approach, using marsupi ....Ancestral, conserved and novel mechanisms in marsupial genomic imprinting. Genomic imprinting is the differential expression pattern of some genes depending on whether the gene copy came from the mother or the father. This differential expression is essential for embryonic development and errors lead to disease. To date, most of our knowledge of the control of genomic imprinting comes from the mouse, but much less is known about this process in marsupials. Our comparative approach, using marsupial mammals that are distantly related to mice and humans, aims to clarify how genomic imprinting mechanisms have evolved, which patterns are conserved across mammals, and which vary. Our proposed research aims to provide new approaches and understanding of this fundamental process essential for the continuation of life.
