mortality/aging
• following withdrawal of doxycycline

cardiovascular system
• after doxycycline withdrawal, mice exhibit a trend towards increased inflammation in the atrioventricular node unlike wild-type mice
• however, there is no evidence of fibrosis, calcification, or necrosis
• mild following withdrawal of doxycycline
• at 15 to 30 weeks after doxycycline withdrawal, mice with congestive heart failure exhibit increase chamber sizes compared with wild-type mice
• following withdrawal of doxycycline
• 30 days following the withdrawal of doxycycline, mice exhibit increased left ventricular end-diastolic dimension compared with wild-type mice
• following withdrawal of doxycycline
• following withdrawal of doxycycline
• at 15 to 30 weeks after doxycycline withdrawal in mice with congestive heart failure
• at 15 to 30 weeks after doxycycline withdrawal, mice with congestive heart failure exhibit depressed hemodynamics compared with wild-type mice
• infrequently after doxycycline withdrawal
• after doxycycline withdrawal, mice exhibit sudden cardiac death associated with cardiac asystole preceded by a short burst of 2:1 block unlike wild-type mice
• after doxycycline withdrawal, mice exhibit bifid P waves with elongation of P-wave duration unlike wild-type mice
• progressive after doxycycline withdrawal
• after doxycycline withdrawal, 4 mice exhibit atrioventricular block with Wenckebach periodicity (i.e. progressive elongation of PR interval followed by dropped ventricular beats) unlike wild-type mice
• after doxycycline withdrawal
• after doxycycline withdrawal
• in 6 of 78 mice 15 to 30 weeks after doxycycline withdrawal
• mild following withdrawal of doxycycline

growth/size/body
• at 15 to 30 weeks after doxycycline withdrawal, mice with congestive heart failure exhibit increase chamber sizes compared with wild-type mice
• following withdrawal of doxycycline

homeostasis/metabolism
• at 15 to 30 weeks after doxycycline withdrawal in mice with congestive heart failure
