Developmental programming and reprogramming of conduction tissue
The cardiac conduction system arises from lineage specification of cardiomyocyte progenitors and functions to generate and propagate electrical impulses within the heart. Our laboratory is seeking to identify the signaling pathways that instruct cardiomyocytes to become conduction cells during normal development. In addition, we have demonstrated that activation of the Notch signaling pathways at later stages of maturation can reprogram differentiated cardiomyocytes into conduction-like cells. Deciphering the signals that instruct cells to adopt a conduction phenotype may ultimately provide insight into regenerative approaches, such as the development of a biologic pacemaker.
Molecular basis of congenital heart defects
Congenital heart defects, including those that give rise to conduction disorders, are a significant cause of morbidity and mortality. Wolff-Parkinson-White (WPW) syndrome affects 1 in 500 people and is characterized by accessory atrioventricular pathways in the heart which bypass the normal conduction system and can result in ventricular preexcitation, palpitations and sudden cardiac death. Our laboratory uses novel genetically modified mouse models to study the developmental processes that go awry and produce functional ectopic myocardial tissue.
