cardiovascular system
• mice treated with tamoxifen at 6-8 weeks of age exhibit ventricular dilation, measured as an increase in end-diastolic and end-systolic volume, within 1-week post-induction
• cardiac chamber enlargement is transitory and recovers to pre-induction levels within 2 months
|
• tamoxifen treated mice show a decrease in left ventricular ejection fraction within 1-week post-induction
• the reduced pump function is transitory and recovers to pre-induction levels within 2 months
|
• echocardiography shows an increase in end-diastolic and end-systolic volume and decreased left ventricular ejection fraction within 1-week post-tamoxifen induction
|
homeostasis/metabolism
• tamoxifen-treated mice show increased fumarate and malate and the glycolytic metabolite glucose-6-phosophate in the myocardium
|
muscle
• tamoxifen treated mice show a decrease in left ventricular ejection fraction within 1-week post-induction
• the reduced pump function is transitory and recovers to pre-induction levels within 2 months
