| Ins-rtTA (or RIP7-rtTA) transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat insulin 2 (Ins2) promoter. When mated to a second transgenic strain carrying a gene under the regulatory control of a tetracycline-responsive promoter element (TRE or tetO), expression of the gene in pancreatic beta cells is induced with administration of the tetracycline analog, doxycycline (dox). This strain provides a Tet-On tool that allows the inducible expression of genes in pancreatic beta cells. | ||||||||||||||||||

Mating System Homozygote x Homozygote (Female x Male) 24-FEB-09 Species laboratory mouse Generation N4+F1 (08-JAN-09) Donating Investigator Douglas Melton, Harvard University Description
These mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat insulin 2 (Ins2) promoter. When mated to a second transgenic strain carrying a gene under the regulatory control of a tetracycline-responsive promoter element (tetO), expression of the gene may be regulated by the tetracycline analog, doxycycline (dox); in the presence of dox, transcription of the target gene is induced in pancreatic beta cells where rtTA is expressed. Induction of rtTA activity was not detected in other tissues. This strain provides a Tet-On tool that allows the inducible expression of genes in pancreatic beta cells. The Donating Investigator reports that homozygotes are viable and fertile.Development
A transgenic construct containing the reverse tetracycline-controlled transactivator (rtTA) gene, 9.5kb 5' regulatory sequence and first intron of the rat insulin 2 gene (RIP7) and polyadenylation site sequence was injected into fertilized (C57BL/6 X CBA)F2 mouse eggs. Founder line 2 with 10 copies of the transgene was established and backcrossed to C57BL/6 for at least 3 generations. The mice were then maintained on the outbred ICR background. The mice were then crosssed to C57BL/6J once at The Jackson Laboratory.

| The tetracycline repressor gene (Tetr), arose from chemically mutated Escherichia coli genome which was screened for tetracycline dependence (Gossen and Bujard, 1992). One mutant with a four amino acid residue change (rTetR) exhibited dependence on tetracycline for induction of the targeted gene and was used in the rtTA construct (Gossen et al, 1995). rTetr was fused at the C-terminus with the viral co-activator, virion protein 16 of the herpes simplex virus (VP-16). | |||

| Molecular Note | A transgenic construct containing 9.5kb 5' regulatory sequence and first intron of the rat insulin 2 gene (RIP7) controlling the reverse tetracycline transactivator (rtTA), as well as the polyadenylation site sequence of the RIP7 gene was injected into fertilized (C57BL/6 X CBA)F2 mouse eggs. Founder line 2 with 10 copies of the transgene was established. When mice are crossed to transgenic mice carrying reporter genes, transgene expression is detected only in pancreatic islet beta cells.
