cardiovascular system
• 6 month old mice exhibit enhanced muscularization of peripheral pulmonary arteries in the lung
• mice exhibit normal right ventricular systolic pressure at 3 months of age but develop elevated right ventricular systolic pressure by 6 months of age
• however, mice do not exhibit right ventricular hypertrophy and show no differences in left ventricular end diastolic pressure or cardiac output at 6 months
• mice exhibit pulmonary arterial hypertension by 6 months of age
• treatment of 6 month old mice with daily intraperitoneal injection of BMP9 for 4 weeks reverses all indices of pulmonary arterial hypertension, returning right ventricular systolic pressure to normal and reversing the enhanced pulmonary arterial muscularization
• monolayers of pulmonary endothelial cells in vitro show increased permeability at baseline and following LPS stimulation
• mice injected with LPS develop increased pulmonary vascular leak compared to wild-type mice
• treatment with BMP9 prevents vascular leak to a similar degree as in wild-type mice

cardiovascular system
• heterozygotes exhibit an increase in wall thickness of muscularized pulmonary arteries
• heterozygotes exposed to hypoxia exhibit impaired muscularization of small pulmonary arteries in both the distal intra-acinar vessels and in proximal preacinar vessels, with 25% less increase in wall thickness compared to controls
• the number of alveoli (and associated capillaries called alveolar-capillary units) per millimeter squared is 40% greater in heterozygotes
• heterozygotes exposed to prolonged hypoxia exhibit impaired pulmonary vascular remodeling, with a smaller increase in pulmonary artery pressure, greater right ventricular hypertrophy, decrease in the number of alveolar-capillary units per millimeter squared, and decreased wall thickness (muscularization) of small pulmonary arteries compared to controls
• increase in mean total pulmonary vascular resistance and in incremental pulmonary resistance
• however total systemic vascular resistance is not different
• increase in mean pulmonary arterial pressure
• however, mean systemic arterial pressure is not different from controls
• heterozygotes exposed to prolonged hypoxia show a smaller increase in pulmonary artery pressure than control mice
• mutants develop mild pulmonary hypertension

respiratory system
• the number of alveoli (and associated capillaries called alveolar-capillary units) per millimeter squared is 40% greater in heterozygotes
• heterozygotes exposed to prolonged hypoxia exhibit impaired pulmonary vascular remodeling, with a smaller increase in pulmonary artery pressure, greater right ventricular hypertrophy, decrease in the number of alveolar-capillary units per millimeter squared, and decreased wall thickness (muscularization) of small pulmonary arteries compared to controls
• the number of alveoli (and associated capillaries called alveolar-capillary units) per millimeter squared is 40% greater in heterozygotes, decreasing the vessels-to-alveoli ratio

cardiovascular system
• mutants with adenovirus-mediated pulmonary overexpression of 5-lipoxygenase to induce inflammation in the lungs exhibit a greater number of muscularized vessels than in the lungs from wild-type mice
• mutants with adenovirus-mediated pulmonary overexpression of 5-lipoxygenase to induce inflammation in the lungs exhibit increased right ventricular systolic pressure compared to wild-type mice with the same treatment, indicating increased sensitivity to stress-induced pulmonary hypertension
• however, mutants exhibit normal right ventricular systolic pressure and do not develop pulmonary hypertension spontaneously under unstressed conditions

immune system
• minor increase in adhesion of leukocytes to the vessel wall in the lungs

mortality/aging
