(Submitter supplied) Familial pulmonary arterial hypertension (fPAH) is associated with mutations in BMPR2. Many of these mutations occur in the BMPR2 tail domain, leaving the SMAD functions intact. In order to determine the in vivo consequences of BMPR2 tail domain mutation, we created a smooth-muscle specific doxycycline inducible BMPR2 mutation with an arginine to termination mutation at amino acid 899. When these SM22-rtTA x TetO7-BMPR2R899X mice had transgene induced for 9 weeks, starting at 4 weeks of age, they universally developed pulmonary vascular pruning as assessed by fluorescent microangiography. more...

Analysis of lung from transgenics expressing a BMPR2 tail domain mutation (BMPR2R899X) in smooth muscle. Nine weeks of BMPR2R899X expression can result in elevated right ventricular systolic pressures (RVSP), producing a mutant phenotype relevant to human pulmonary arterial hypertension (PAH).

(Submitter supplied) Pulmonary arterial hypertension (PAH) is thought to be driven by dysfunction of pulmonary vascular microendothelial cells (PMVEC). Most hereditary PAH is associated with BMPR2 mutations. However, the physiologic and molecular consequences of expression of BMPR2 mutations in PMVEC are unknown.

Analysis of PMVECs cultured from triple transgenics carrying immortomouse gene, a transactivator, and either control, Bmpr2delx4+ or Bmpr2R899X mutation. Hereditary pulmonary arterial hypertension is often associated with BMPR2 mutations. Results provide insight into role of Bmpr2 in endothelium.

(Submitter supplied) Background: Right ventricular (RV) and left ventricular (LV) myocardium differ in their response to pressure-overload hypertrophy (POH). In this report we use microarray and proteomic analyses to identify pathways modulated by LV-, and RV-POH in the immature heart. Methods: Newborn New Zealand White rabbits underwent banding of the descending thoracic aorta (LV-POH; n=6). RV-POH was achieved by banding the pulmonary artery (n=6). more...
