Congenital heart diseases are the most common class of birth defect. However, their cause is often unknown.

Our laboratory is interested in the underlying molecular mechanisms of congenital heart disease (CHD). To achieve our goals we are using various approaches including experimental embryology, genetics, and transcriptomic experiments.

Our goals are to better understand the biological processes controlling the development of mouse and human hearts in order to identify and treat the causes of cardiac diseases. We are specifically interested in the arterial and venous poles as well as in valve development, as they are affected in the majority of CHD.

Our research focuses on the molecular programs controlling cell fate decisions between distinct embryonic cell lineages, derivatives of the neural crest and mesoderm, in the early heart. Our work over the past few years has established a novel role for a number of genes during cardiovascular development and identified several candidate genes for less-studied CHD such as bicuspid aortic valve or syndromic heart anomalies in rare malformation syndromes.

Our work over the past few years has established the role of retinoic acid in defining the boundary of the heart fields during early development. Inhibition of retinoic acid signaling leads to expansion of cardiac progenitors. We have also shown that anterior Hox genes, as downstream targets of retinoic acid, are expressed in distinct domains of the second heart field contributing to the outflow tract and atria. Using mutant mouse embryos, we have recently demonstrated that Hoxb1 regulates proliferation and differentiation of second heart field progenitors and genetically interacts with Hoxa1 during cardiac outflow tract development. The role of retinoic acid signal and Hox genes in the patterning of the second heart field is being investigated.

Finally, elucidating the mechanisms involved in the restriction of cardiac progenitors will lead to a better understanding of CHDs and will ultimately lead to the development of novel therapies aimed at healing impaired human hearts.

Anomalies of heart valves, including bicuspid aortic valve (BAV), are some of the commonest CHDs. Extracellular matrix changes occur in many valvular diseases. However, the molecular mechanisms leading to these pathologies are poorly understood. We have recently discovered the role of the zinc finger transcription factor Krox20 (Egr2) during heart valve development in mice. Loss of Krox20 function leads to defective aortic valve structure associated with aortic dysfunction. Functional promoter analysis demonstrated that Krox20 regulates the fibrilar collagens Col1a1 and Col3a1 genes during the remodeling of aortic valves. We continue our studies to uncover the contribution of different lineages in valve development and disease. We are now using state-of-the-art genetic technologies including next generation whole exome sequencing with the goal of discovering new genes in aortic valve disease such as BAV.
