Research Interests

Pulmonary arterial hypertension (PAH) is characterized by structural remodeling and narrowing of pulmonary arteries. Such vascular remodeling increases the pulmonary vascular resistance and ultimately leads to right ventricular failure. The 5-year survival is currently only 66%, highlighting the importance of better understanding the underlying disease mechanisms to pave the way for targeted therapies. I’m currently focusing on the following two related projects:

1. Recently a novel frameshift mutation in Caveolin-1 (Cav1) was identified in a family with heritable PAH. This frameshift mutation leads to caveolin-1 protein that contains all known functional domains but has a change only in the final 20 amino acids of the C terminus. By using patient-derived fibroblasts, we hope to understand how this mutation leads to PAH.

2. While it has been known for a while that mutations in BMPR2 are responsible for most cases of familial PAH, there are no specific treatments available for these patients. We want to use CRISPR-mediated gene correction in vivo to specifically make changes in the genetic material of pulmonary arterial endothelial cells as a novel treatment for PAH.
