A novel microtubule severing protein involved in male germ cell biology. The project aims to better understand the cellular and biochemical mechanisms underlying a key component of male fertility. Microtubules are a fundamental component of all cells. A mechanism that is increasingly recognised as essential for microtubules regulation is severing. It has been discovered that an uncharacterised microtubule severing protein, KATNAL2, has a key role in male germ cell development.

The project aims to better understand the cellular and biochemical mechanisms underlying a key component of male fertility. Microtubules are a fundamental component of all cells. A mechanism that is increasingly recognised as essential for microtubules regulation is severing. It has been discovered that an uncharacterised microtubule severing protein, KATNAL2, has a key role in male germ cell development. This project aims to define the mechanisms underlying KATNAL2 function in the male germ line. It is expected that these data will generate a comprehensive picture of KATNAL2 function and provide foundation data of relevance across multiple species and tissues. In the longer term, it may also reveal a rational strategy for fertility enhancement or suppression.Read moreRead less
Interactions between cells and extracellular matrix in the epithelial-mesenchymal transition of the ovarian follicular stratified epithelium. The lining of many mammalian organs and cavities contain cells that can transform into different cells to bring about organ development or repair but if it goes horribly wrong the cells become metastatic cancers. This project examines the key features of this process especially the roles of matrix that develops around the cells in this process.
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
Is Calcium part of the mechanism used in glucose signalling in embryogenesis. A vital stage in the development of the embryo is formation of the blastocyst about 4 days after conception. For this to happen the embryo must receive glucose from the mother. We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The pr ....Is Calcium part of the mechanism used in glucose signalling in embryogenesis.

We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The project investigates this signal mechanism. The results will advance understanding of the mechanisms regulating development and in particular link the mother's nutritive status to her fertility during very early pregnancy.Read moreRead less
Who determines gestation length - mother or fetus? This project will extend our knowledge of a key biological process - pregnancy. Variation of gestation length by 10% is generally deleterious to the offspring, and smaller babies have been shown to be more susceptible to later life diseases. Therefore, extension of the information gained from this project will likely impact researchers in species conservation, pest control, and the livestock industries, as well as human, obstetric care and pract ....Who determines gestation length - mother or fetus?

Therefore, extension of the information gained from this project will likely impact researchers in species conservation, pest control, and the livestock industries, as well as human, obstetric care and practice. Specifically, knowledge gained from this project may lead to means of limiting (pest control) as well as enhancing (endangered species) species survival.Read moreRead less

This project will benefit the community by informing service provision for infertility treatment, and by identifying the potential for prevention strategies. It will consolidate Australia's position at the forefront of research into assisted reproductive technologies, through the extension of this expertise to our near neighbours. It will contribute to the current gap in knowledge of infertility in Southeast Asia and in developing countries more broadly, and advance research on infertility conducted from human rights and anthropological perspectives. The project will reinforce the relevance of the United Nations definition of reproductive health, for all people regardless of whether they live in highly or lesser developed nations.Read moreRead less
Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can ....Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can better support Australian families with planning and rearing children. A key outcome will be a Parenting Decision-Aid to provide evidence-based reader-friendly information about the positives and negatives of first-time parenthood at different ages.Read moreRead less
