Effect of BMPR2 mutation on vascular smooth muscle gene expression

BMPR2 mutation is the cause of most hereditary pulmonary arterial hypertension, but the common molecular consequence of different types of BMPR2 mutation is still not known. The goal of this study was to determine the common molecular consequences of three different classes of patient-derived BMPR2 mutation in vascular smooth muscle gene expression. Three different classes of BMPR2 mutation, wild-type BMPR2, or empty vector were stably transfected into A7R5 vascular smooth muscle cells, and expression compared.
