cardiovascular system
• after a 5-wk hypoxic exposure (10% O2), hypoxia-induced increases in RV mass are significantly higher in heterozygous than in wild-type (294% vs. 265%, respectively)
• after a 5-wk hypoxic exposure (10% O2), hypoxia-induced increases in right ventricular (RV) pressure are significantly higher in heterozygous than in wild-type mice (637% vs. 4510%, respectively)
• when fed on standard chow (0.8% NaCl) for 2 weeks, heterozygotes display normal blood pressures and normal heart rates relative to wild-type
• when fed on high salt chow (8% NaCl) for 2 weeks, heterozygotes become hypertensive, with blood pressures elevated by 27 mm Hg relative to wild-type; heart rates remain unaffected relative to wild-type

muscle
• after a 5-wk hypoxic exposure (10% O2), hypoxia-induced increases in RV mass are significantly higher in heterozygous than in wild-type (294% vs. 265%, respectively)

growth/size/body
• after a 5-wk hypoxic exposure (10% O2), hypoxia-induced increases in RV mass are significantly higher in heterozygous than in wild-type (294% vs. 265%, respectively)
