Abstract excerpt
Previous studies of pulmonary arterial hypertension (PAH) have implicated excessive transforming growth factor (TGF)-β1 signaling and reduced bone morphogenetic protein (BMP) signaling in the disease pathogenesis. Reduced BMP signaling in pulmonary artery smooth muscle cells (PASMCs) from patients with heritable PAH is a consequence of germline mutations in the BMP type II receptor (BMPR-II). We sought to...
