Understanding the pathogenesis of gestational diabetes
Gestational diabetes mellitus (GDM) affects up to 20% of all pregnancies but have an impact that extends well beyond pregnancy and childbirth, with the potential for lifelong morbidity or mortality for both mother and baby.
Despite the enormous health-impact of GDM, little progress has been made with interventions aimed at prevention. An efficacious medical therapeutic that can prevent the development of GDM would be a major advance. Such treatments do not exist and their development is hampered by the fact the pathophysiology of GDM is incompletely understood. Current therapy for GDM is largely “glucocentric”, with the major therapeutic goal being achievement of glucose levels as close to normal pregnancy values as possible. However, these current therapies do not target inflammation, which is critical to both disease pathogenesis and long-term outcome in GDM.
This project will investigate whether major regulators of inflammation such as sirtuin 1 (SIRT1) are involved in the pathophysiology of GDM.
