Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infer ....Mechanisms of manchette function. This project aims to define the function of the manchette, a poorly understood microtubule-based structure present in haploid male germ cells. This project aims to define key mechanisms underpinning manchette development and movement, and to generate a detailed picture of the dynamics of germ cell development using imaging technologies and unique animal models. Such knowledge should improve the understanding of how male fertility is achieved, the origin of infertility and how species-specific differences in sperm form are achieved. Such insights may ultimately lead to improved agricultural efficiencies and job creation.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. 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 a non-surgical method of contraception in companion/feral species, which should address the large unmet need for fertility control in these animals.

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.

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-art approaches. Expected outcomes and benefits include an enhanced knowledge of the mechanisms underpinning fertility and infertility, enhanced collaboration and research knowhow, and an evidence base for future applied projects aimed enhancing fertility in agricultural species.Read moreRead less
The impact of environmental toxicants on the fertility of female animals. This study aims to address a problem of national significance; determining the impact of commonly used environmental toxicants (pesticides) on the fertility and health of female animals, both agricultural and native. This project expects to generate new knowledge in the fields of ovarian biology, female fertility and toxicology by using a combination of mouse and marsupial animal models. The expected outcomes include the e ....The impact of environmental toxicants on the fertility of female animals. This study aims to address a problem of national significance; determining the impact of commonly used environmental toxicants (pesticides) on the fertility and health of female animals, both agricultural and native. This project expects to generate new knowledge in the fields of ovarian biology, female fertility and toxicology by using a combination of mouse and marsupial animal models. The expected outcomes include the establishment of interdisciplinary collaborations and provision of world-class training for staff and students in the field of reproductive biology. This project should provide significant benefits, such as improved chemical management in livestock production and the development of marsupial conservation action plans.Read moreRead less
Enhancing fertility for the Thoroughbred and Standardbred industries. Enhancing fertility for the Thoroughbred and Standardbred industries. Responding to industry calls for improved methods of detecting and managing infertility in both stallions and mares, this project aims to provide a platform for competitive collaborations between universities, biotechnology companies and horse breeders: the end-users of technological developments in equine reproduction.

Responding to industry calls for improved methods of detecting and managing infertility in both stallions and mares, this project aims to provide a platform for competitive collaborations between universities, biotechnology companies and horse breeders: the end-users of technological developments in equine reproduction. The Thoroughbred and Standardbred breeding industries contribute over $6.5 billion per annum to the Australian economy and employ thousands of staff across their value chains. However, these industries suffer from breeding program inefficiencies that amount to over $800 million in annual losses. Expected outcomes are novel reproductive technologies and specialised research capabilities that will make the Australian equine industry a global leader.Read moreRead less
Enhancing the efficiency of equine reproduction: relevant to the Thoroughbred and Standardbred breeding industries. The purpose of this project is to link the equine breeding industry with a major centre of reproductive research at the University of Newcastle. By creating this unique nexus, major efficiency gains will be achieved for this industry that will not only secure its international competitiveness but also significantly enhance its profitability.

Summary
Defining single-strand DNA break repair capacity in oocytes. This project aims to investigate fundamental biological mechanisms required for the production of high-quality oocytes, which fortify female fertility and the propagation of all sexually reproducing species. Exploiting unique mouse models, this study will define the importance of single strand DNA break repair capacity in oocytes for the first time, by outlining the role of single strand DNA repair proteins in maintaining genetic integ ....Defining single-strand DNA break repair capacity in oocytes. This project aims to investigate fundamental biological mechanisms required for the production of high-quality oocytes, which fortify female fertility and the propagation of all sexually reproducing species. Exploiting unique mouse models, this study will define the importance of single strand DNA break repair capacity in oocytes for the first time, by outlining the role of single strand DNA repair proteins in maintaining genetic integrity of gametes throughout their lifespan. In doing so, the intended outcome of this project is to dramatically improve our understanding of quality control in the female germ line. This should provide significant benefits to Australia by positioning it as a world leader in the field of Reproductive Science.Read moreRead less
