Summary
One in four pregnancies in Australia will end in miscarriage. Infertility affects about 15% of Australian couples and is highly correlated with increasing maternal age. In this study, we will use cutting edge single-cell genomic approaches to investigate the activity of mobile DNA elements or “jumping genes” as a previously unexplored cause of reproductive failure, including spontaneous miscarriage and age-related female infertility.
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.
Sperm Methylation Status Predicts Embryo And Pregnancy Outcomes In Male Obesity

Summary
The incidence of male obesity in reproductively age men is epidemic and continually rising with close to 70% of men of reproductive age classified as overweight or obese. Male obesity is not only associated with sub fertility but also changes to pregnancy outcomes and influencing child health. This project will try to uncover the molecular changes in sperm, providing potential mechanisms for the abnormal foetal and pregnancy health seen as a result of male obesity.
The Role Of The Actin Remodelling Protein, Flightless I, In Tissue Regeneration

Summary
Human embryos possess the remarkable capability to repair wounds perfectly with no scarring, unlike adults for whom major trauma can result in life-long disfigurement and immobility. We have identified a method that may be able to reinitiate the ability to repair wounds perfectly and we will test whether this is the case using animal models of fetal repair.
