Defective pulmonary vascular remodeling in Smad8 mutant mice.

Abstract excerpt

Pulmonary artery hypertension (PAH), a progressive, lethal condition that results in pathologic changes in the pulmonary arterial tree, eventually leads to right heart failure. Work identifying mutations in the Type II Bone morphogenetic protein (Bmp) receptor, BmpRII, in families with PAH has implicated Bmp-signaling in the pathogenesis of PAH. However, the effectors downstream of BmpRII in PAH remain unclear...
