Metabolic And Molecular Basis Of Embryo Signalling

Summary
Cells in the body are powered by mitochondria that essentially generate the energy required for development. This grant will determine how the environment affects the mitochondria in the developing embryo and determine the impacts to the embryo and pregnancy if a mitochondria is partially shut down.
Improving Oocyte Mitochondrial DNA Copy Number To Enhance Female Reproductive Capacity.

Summary
Eggs with too few copies of mitochondrial DNA either fail to fertilise or arrest during early development. By supplementing eggs with mitochondrial DNA, we have been able to enhance embryo quality and gene expression profiles. By breeding the offspring derived from eggs given mitochondrial supplementation, we will determine if they and their progeny meet normal developmental milestones, regulate the transmission of mitochondrial DNA appropriately, and are healthy and fertile.
Health And Fertility Of Young Men Conceived Using Intra-cytoplasmic Sperm Injection

Summary
The injection of a single sperm into the egg (ICSI) has been the main IVF treatment for men with poor sperm quality since 1993 but is now often used for other types of infertility. Concern has been raised about the health of the children. We will approach >800 parents and their adult sons conceived using ICSI and will assess his general health and development, and fertility. This work will improve patient counselling and practice guidelines, and direct research into the safety of ICSI.
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
Clinical Review Of A Cohort Aged 22-33 Years Conceived Using Assisted Reproductive Technologies

Funding Amount
$946,454.00
Summary
In a recent study, using telephone-interviews, we compared the health and wellbeing of 547 singleton young adults born following assisted reproductive technologies (ART), with 549 matched controls. Reviewing their health when they are 22-33 years is possible because of their ongoing interest. We have a protocol in place to measure their cardiac and respiratory function and other aspects of growth and development. Our findings will fill a major knowledge gap about the longer term safety of ART.
Dissecting the impact of stress on reproduction: Novel peptide mediates inhibitory effects of stress on female reproduction. This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining go ....Dissecting the impact of stress on reproduction: Novel peptide mediates inhibitory effects of stress on female reproduction. This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining good health. Given that suppression of reproduction by stress occurs in all mammalian species including humans, domestic animals and wildlife, being able to prevent or overcome stress-induced reproductive dysfunction will generate significant health, social, economic and ecological benefits.

Targeting The Anti-angiogenic Factors Of Preeclampsia: Soluble Endoglin And SFlt1
Funder

Funding Amount
$447,024.00
Summary
Preeclampsia is a severe disease of pregnancy - the placenta releases toxins in to mum's bloodstream that circulate her body and damage her organs. As there are no efficacious treatments, clinicians are forced to deliver babies irrespective of gestation. Although the two toxins of preeclampsia have been identified, little is known about their regulation. This project aims to elucidate the regulation of these toxins and design therapeutics that can prevent their release in the clinic.
Combination Methotrexate And Gefitinib To Cure Ectopic Pregnancies: Phase I-II Clinical Trials

Funding Amount

Summary
Ectopic pregnancies are dangerous emergencies that can cause fatal bleeding. Most require surgery. We plan to test a novel medication-based treatment that could be used to cure most ectopics. If successful, it could revolutionise current management.
Soluble Endoglin In The Pathogenesis Of Preeclampsia: Investigation Of Mechanisms And The Development Of Therapeutics
Funder

Funding Amount
$572,733.00
Summary
Preeclampsia is a severe disease of pregnancy. As the pathogenesis is poorly understood, the only treatment is for clinicians to deliver babies irrespective of gestation. We have identified MMP-14 as the molecular scissors that release soluble endoglin from placenta, a toxin centrally responsible for severe preeclampsia. In this project we aim to further investigate the mechanisms governing soluble endoglin release and to begin developing a potential therapeutic for use in the clinic.
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
