cardiovascular system
• hypertrophy of cardiomyocytes occurs after 6 weeks of aortic banding to mice that have had cre expression induced
• left ventricular end systolic volume is increased after cre induction from 0.017 cm3/g to 0.021 cm3/g
• after cre induction, the left ventricular ejection fraction is depressed from 0.65 cm3/g to 0.60 cm3/g
• heart rate is depressed after cre induction from 443 bpm to 441 bpm
• male mice with cre induction and intracardiac electrical stimulation have more ventricular tachycardia episodes than controls (17 vs. 3)
• duration of these episodes are also about 3-fold longer than controls

growth/size/body
• mice in which cre expression is induced have more weight loss than controls in response to exercise

homeostasis/metabolism
• mice with cre expression have a reduced exercise capacity

muscle
• hypertrophy of cardiomyocytes occurs after 6 weeks of aortic banding to mice that have had cre expression induced
• after cre induction, the left ventricular ejection fraction is depressed from 0.65 cm3/g to 0.60 cm3/g

behavior/neurological
• mice with cre expression have a reduced exercise capacity
