Determining The Impacts Of Epigenetic Modifying Drugs On Germline Programming And Offspring Health

Funding Amount
$863,918.00
Summary
New drugs have been developed that inhibit specific enzymes that regulate epigenetic pathways in cells. These pathways significantly affect growth and development in offspring and may represent a risk to future children of patients taking the drug. This project will determine these risks and provide data for developing clinical guidelines for safe use of the drugs.
Female Reproductive Health Preservation By Nicotinamide Adenine Dinucleotide (NAD+) And Sirtuin2 (SIRT2)

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.

Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks. Using laboratory animals, we have developed significant new insights into mechanisms regulating egg quality.

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.
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.
Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks. Using laboratory animals, we have made significant advances towards developing new technologies that can mature eggs and produce embryos in vitro, but without women receiving hormone injections. This project will seek means to combine the benefits of two of our existing technologies into one integrated system, to provide hormone-free infertility treatment.
Understanding Mitochondrial DNA Segregation And Transmission.

Funding Amount

Summary
We inherit our mitochondrial DNA from our mothers. Mutations to mitochondrial DNA can give rise to severely debilitating diseases that can be passed from one generation to the next. The aims of this application are to understand how mutant mitochondrial DNA is selected for; when it affects energy production during development; and to ensure that certain reproductive strategies do not result in the adverse transmission of mitochondrial DNA that will affect subsequent generations.
As women age, the quality of their eggs decline and their chance of having a healthy baby plummets. The accumulation of DNA damage within the egg, and the reduced ability to repair this damage, may be one cause of compromised reproductive success in older women. This project will investigate the ability of eggs to repair DNA damage during maternal aging and will explore the importance of DNA repair to fertility and the transmission of high quality genetic material to their offspring.
Understanding Epigenetic Modification During Oogenesis For Novel Treatments Of Female Infertility

Summary
Infertility affects about 10% of Australian women and the success rates of current infertility treatments are low due to our poor knowledge of eggs development. The numbers of obese and older women trying to conceive are increasing; fertility treatments are even less effective for them. I have generated mouse models to elucidate the pathways regulating egg development. I will study for alterations in these pathways in the mouse models which perfectly mimic the obesity and aging in women.
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.
