The critical role of kisspeptin/neurokinin/dynorphin (KNDy) neurons in gonadotropin releasing hormone (GnRH) release. The brain controls fertility through the secretion of its primary stimulatory factor, gonadotropin releasing hormone (GnRH). Brain cells producing three key peptide hormones, kisspeptin, neurokin B and dynorphin (termed KNDy cells) are vital for the control of GnRH. This project will detail the role of KNDy cells in puberty and reproduction.
Building child health through maternal wellbeing. Chronic diseases partly originate in the health & social circumstances of previous generations, during pregnancy, and in conditions during infancy and childhood. This project will draw from three community studies the researcher established to investigate how aspects of women's health affect their children's health and identify new opportunities for disease prevention.
Defining the pathways of developmental brain injury, for a healthy start to life. Injury to the developing brain, whether sustained during pregnancy or at birth, is the underlying cause of many cognitive and motor disabilities, including cerebral palsy. This project will identify the cellular pathways that cause developmental brain injury, arising from the three principal complications of pregnancy or birth; intrauterine growth restriction (IUGR), preterm birth with/without intrauterine infectio ....Defining the pathways of developmental brain injury, for a healthy start to life. Injury to the developing brain, whether sustained during pregnancy or at birth, is the underlying cause of many cognitive and motor disabilities, including cerebral palsy. This project will identify the cellular pathways that cause developmental brain injury, arising from the three principal complications of pregnancy or birth; intrauterine growth restriction (IUGR), preterm birth with/without intrauterine infection and birth asphyxia. This project will utilise this knowledge of the causal pathways leading to brain injury to implement targeted therapies to reduce injury or repair the brain. It will progress fundamental biomedical discoveries into clinical practice to decrease the incidence and severity of newborn brain injury and cerebral palsy.Read moreRead less
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

FACSAria III - Fluorescence activated cell sorter. Flow cytometry is a technique for counting and examining microscopic particles, such as cells and chromosomes, by suspending them in a stream of fluid and passing them by an electronic detection apparatus. The FACSAria III cell sorter will be used to establish a core facility for sorting cells. The outcomes from using this technology are a better understanding cellular and genetic understanding of cancer, respiratory diseases, reproduction and ....FACSAria III - Fluorescence activated cell sorter.

Understanding gonadal development and disease using a unique model system, the avian embryo. This project will provide information on normal and abnormal gonadal development during embryonic life. The study will aid in the diagnosis and management of humans born with disorders of sexual development and will be useful for sex ratio manipulation in the poultry industry.
Genetic regulation of testis development in the chicken embryo. This project aims to shed light on the genetic control of testis development during embryonic life, using the chicken embryo as a model. The results will have implications for sex ratio manipulation in poultry and for our understanding of sexual disorders in humans.
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.

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
Heme oxygenase integrates cellular responses to oxygen stress. A deficiency in the protein heme oxygenase-1 causes severe biological consequences including retarded development, chronic inflammation and increased susceptibility to age-associated diseases. By illuminating how heme oxygenase-1 improves cell function the project will eventually assist in preventing or slowing the serious age-associated disorders.
Differential roles of gene family members in development of a cell lineage. This project aims to investigate how a family of genes influence cells in the testis to become mature sperm. Testicular cells regulate gene activity via the Snail family of proteins during sperm development, and interruption of their activities reduces fertility in mice and fruit flies. The project aims to use genetic, cell biological and biochemical studies in Drosophila and mice to compare different Snail family protei ....Differential roles of gene family members in development of a cell lineage. This project aims to investigate how a family of genes influence cells in the testis to become mature sperm. Testicular cells regulate gene activity via the Snail family of proteins during sperm development, and interruption of their activities reduces fertility in mice and fruit flies. The project aims to use genetic, cell biological and biochemical studies in Drosophila and mice to compare different Snail family proteins in spermatogenesis. The outcomes will define the different roles of highly similar proteins from the same family in differentiation of a single cell lineage. This is important in generating functional tissues using in vitro laboratory approaches or understanding how normal development and developmental disorders arise.Read moreRead less
