You wish to study how the size of the heart is regulated during development. You decide to use a genetic system where the gene BEAT1 (specifically expressed in heart progenitors) drives rtTA. When doxycycline (dox) is added, rtTA binds to the tetracycline operator (tetO) to activate transcription. Your transgenic mice also carry a responder element with tetO driving the expression of diphtheria toxin (DTA). What effect will the addition of dox have on BEAT1-expressing cells?
