Summary
Cancer treatment can be severely toxic to women’s eggs. Increasing numbers of women who survive cancer therefore become infertile and prematurely deprived of hormonal support whilst still in their reproductive years. This project will use state-of-the-art techniques to interrogate newly uncovered pathways that can protect eggs from treatment-induced injury thereby greatly improving the quality of life for female cancer survivors.
Nicotinamide Adenine Dinucleotide (NAD+)-raising Agents For Improving Oocyte Quality

Summary
Many women cannot have children because of suboptimal egg quality, often due to aging. Currently, the only option is to use better quality eggs donated from another woman. This project will use pharmacological agents to promote recently discovered pathways in eggs central to determining quality. Importantly, we will investigate a simple and practical approach that can be used in clinics for augmenting these pathways to improve oocyte quality for the first time.
Life-saving chemo/radio-therapy commonly renders women and girls who survivor cancer infertile or sterile. We have discovered a new means of preserving the fertility of female mice exposed to chemo/radio therapy. In this project we will apply these advances to human ovarian tissue/eggs for the first time. We have access to these rare tissues for research purposes. This project will develop new approaches to fertility preservation for cancer survivors.
Role Of The Anaphase-Promoting Complex Activator Cdh1 In Oocyte Maturation And Meiotic Aneuploidy

Summary
Eggs containing an incorrect number of chromosomes are described as aneuploid. This project sets out to examine the molecular causes of aneuploidy and why it increases with female age. We focus on the protective role of the protein Cdh1 in this process. The outcome would be to better understand the origins of aneuploidy so as to find methods of decreasing it as women age. This is highly significant given aneuploidy is the leading cause of early embryo loss and produces Down Syndrome babies.
Targeting PI3K-regulated Small Non-coding RNAs To Restore Cardiac Function

Summary
Heart failure affects approximately 2.4% of the adult population and over 11% of people over 80 years old. The majority of existing therapies slow, rather than reverse heart failure progression. The primary goal of this study is to determine whether regulating novel regulatory genes can enhance cardiac function in a setting of heart failure. Ultimately, technologies that target these genes may lead to innovative pharmacotherapies in the clinical management of heart failure.
Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead ....Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead to an additional uptake of atmospheric carbon dioxide into the global ocean, maybe some additional buffering against ocean acidification, but unfortunately, maybe also a loss of carbonate ecosystems. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle.

Can eco-evolutionary theories explain outcomes of microbiome coalescence . Environmental microbial communities are among the most abundant and diverse natural communities, responsible for many ecologically and economically important ecosystem functions, including primary productivity and climate regulation. This project aims to identify the biotic and abiotic factors that regulate community and functional outcomes of microbiome coalescence (the mixing of two different communities) caused by natu ....Can eco-evolutionary theories explain outcomes of microbiome coalescence . Environmental microbial communities are among the most abundant and diverse natural communities, responsible for many ecologically and economically important ecosystem functions, including primary productivity and climate regulation. This project aims to identify the biotic and abiotic factors that regulate community and functional outcomes of microbiome coalescence (the mixing of two different communities) caused by natural and anthropogenic activities. The outcomes will provide a unifying ecological framework to predict variation in microbiomes across different scales, ecosystem types and disturbances, and will generate critical knowledge for the development of effective microbiome products, a rapidly growing industryRead moreRead less
The Structural Basis For Glutamate Transporter Function

Funding Amount
$373,144.00
Summary
Glutamate transporters are vacuum cleaners in the brain that suck the neurotransmitter glutamate into cells. When the glutamate vacuum breaks down or becomes blocked, glutamate levels outside cells increase, leading to cell death in the brain. This process underlies the damage in many brain diseases including Alzheimer’s disease and stroke. The aim of this project is to understand the mechanism of the glutamate vacuum cleaner so we can develop therapeutics to fix it when it breaks down.
Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport). The pr ....Placental nutrient transport shows how complex traits evolve.

Lively reproduction: do common molecules underlie all vertebrate live birth? Most animals lay eggs, but some (most mammals, including humans and some reptiles) give birth to live young. This project will reveal the molecules underlying the evolution of live birth and fundamental processes of early pregnancy, which potentially will lead to future developments in reproductive science.
