Summary
Many birth defects are due to damage sustained by the eggs before ovulation. Aging allows more damage, hence the advice to have babies earlier in life. However, we believe we have identified a source of damage that happens during late development of the follicle in the weeks before ovulation. Proving this will enable us define when an egg is most at risk of damage and to devise strategies to lower the risk.
Molecular Basis For Female Age-associated Decline In Oocyte Quality And Fertility

Summary
Many women cannot have children because of suboptimal egg quality, often due to ageing. In order for novel strategies to be developed for improving egg quality, it will first be important to understand how key factors in eggs are regulated. This project will use state-of-the-art techniques to interrogate a pivotal pathway we have discovered in eggs that could be responsible for age-related decline and could hold the key to new approaches for rejuvenating eggs.
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.
