Mating System Homozygote x Homozygote (Female x Male) 05-FEB-09 Species laboratory mouse Generation F?+F1 (02-JAN-09) Donating Investigator Douglas Melton, Harvard University Description
These tet-DTA transgenic mice express diphtheria toxin A (DTA) under the control of a tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) and a cytomegalovirus minimal promoter. When bred with another mouse expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), tissue diphtheria toxin A expression can be regulated with the tetracycline analog doxycycline (dox) in the resulting double mutant offspring. These tet-DTA mice may be useful in generating bi-transgenic mutant mice for the reversible, inducible deletion of specific groups of cells.For example, when bred to a strain expressing tTA in cardiac myocytes (see Stock No. 003170 for example), this mutant mouse strain may be useful in studies of human cardiomyopathies.
Development
The tet-DTA transgene was designed with a diphtheria toxin A (DTA) sequence under the control of heptamerized tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) sequences and a cytomegalovirus minimal promoter. This transgene was injected into fertilized B6CBAF2 mouse eggs. Founder animals were bred to outbred ICR mice and then made homozygous prior to arrival at The Jackson Laboratory.

involves: C57BL/6 * CBA
- lethality-prenatal/perinatal
- embryonic lethality during organogenesis (MGI Ref ID J:128617)
- in absence of maternal supplementation with tetracycline (Tc) during gestation, no binary (or double) transgenic offspring are born, whereas gestational or perinatal suppressive Tc treatment results in Mendelian numbers of binary offspring (22%)
- genotypic analysis at times throughout gestation show that death of double transgenic embryos occurs between 10.5 days post conception (dpc) and fetal day 19
- life span-post-weaning/aging
- premature death (MGI Ref ID J:128617)
- when Tc treatment is withdrawn after birth, mortality results with median survival time of 37 days (earliest time of death is 12 days after withdrawal of Tc, latest death is 77 days); death occurs suddenly with no indication of illness
- cardiovascular system phenotype

- abnormal impulse conducting system conduction (MGI Ref ID J:128617)
- at 1 month after tetracycline withdrawal, a subset of isolated-perfused hearts display markedly disturbed activation profiles, with either disorganized conduction or evidence of block during pacing
- majority of even mildly diseased hearts are arrhythmogenic
- cardiac fibrosis (MGI Ref ID J:128617)
- ventricles show mild patchy fibrosis to severe fibrosis following Tc withdrawal
- decreased myocardial fiber number (MGI Ref ID J:128617)

- increased cardiomyocyte apoptosis (MGI Ref ID J:128617)
- some hearts display severe cell loss following tetracycline withdrawal
- irregular heartbeat (MGI Ref ID J:128617)
- following Tc withdrawal, a variety of arrhythmias are detected in double transgenic mice which show increased propensity to develop reentrant tachycardia, including atrial fibrillation, pauses, and complex ventricular ectopy such as runs of ventricular tachycardia
- majority of even mildly diseased hearts are arrhythmogenic
- atrial fibrillation (MGI Ref ID J:128617)
- following tetracycline withdrawal, atrial fibrillation occurs in some mice
- ventricular tachycardia (MGI Ref ID J:128617)
- at 1 month after Tc withdrawal, most isolated-perfused hearts display either spontaneous or inducible ventricular tachycardia, including both sustained and nonsustained runs of ventricular tachycardia with some episodes lasting
- muscle phenotype
- decreased myocardial fiber number (MGI Ref ID J:128617)
- hearts show evidence of mild to severe myocyte loss
- increased cardiomyocyte apoptosis (MGI Ref ID J:128617)
- some hearts display severe cell loss following tetracycline withdrawal
- homeostasis/metabolism phenotype
- atrial thrombosis (MGI Ref ID J:128617)
- mural thrombus formation is prominent in atrial tissue in some animals following Tc withdrawal
