cardiovascular system
• stroke volume is reduced by ~10% in transgenic mice
|
• systemic vascular resistance is reduced by ~10% compared to controls
|
• transgenic mice display ~10% increase in heart rate
|
• mean arterial pressure is reduced by ~10% compared to controls
|
• pressure is lower (105.9 mm Hg) than in age- and weight-matched conscious controls (112.7 mm Hg)
• systolic pressure difference is greater (13 mm Hg) in anesthetized transgenics (76 mm Hg) compared to controls (89 mm Hg)
|
homeostasis/metabolism
• nitric oxide synthase (NOS) activity is significantly increased in transgenic skeletal muscle; cardiac tissue homogenates have higher NOS activity
|
• transgenic skeletal muscle homogenates have greater NOS activity
