Reversible in vivo DN-CBRb transgene regulation. P10 DN-CBRb+/ROSA-CAG-rtTA+ mice were fed with Dox in drinking water for 10 consecutive days. Untreated animals of the same genotype were used as control group (Group 1; -Dox). At the end of Dox treatment animals were euthanized either immediately (Group 2; +Dox) or 5 days after Dox withdraw (Group 3; ±Dox). Supporting the reversibility of the system, RB1 levels were visibly decreased on group 2. Nevertheless, cochleae collected 5 days after Dox withdraw showed RB1 levels, which were comparable to those of the control group.
