These MMTV-rtTA mice have expression of the reverse tetracycline-controlled transactivator (rtTA) protein directed primarily to the breast epithelia of the mammary ductal system by the mouse mammary tumor virus (MMTV) promoter. The donating investigator also reports some rtTA expression in salivary glands (particularly in males) as well as prostate glands. These mice are a Tet-On tool that allows conditional, dox-inducible expression of genes primarily in mammary gland epithelial cells and may be useful in studying the endocrine function of mammary tissues and/or breast cancer (for example).

Description

The genotypes of the animals provided may not reflect those discussed in the strain description or the mating scheme utilized by The Jackson Laboratory prior to cryopreservation. Please inquire for possible genotypes for this specific strain.

Description
The donating investigator claims homozygous mice are viable and fertile. These MMTV-rtTA mice have expression of the reverse tetracycline-controlled transactivator (rtTA) protein directed primarily to the breast epithelia of the mammary ductal system by the mouse mammary tumor virus (MMTV) promoter. The donating investigator also reports some rtTA expression in salivary glands (particularly in the males) as well as prostate glands. When mated to a mutant strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE, TetRE or tetO), expression of the target gene may be induced with administration of the tetracycline analog doxycycline (dox) in the double mutant offspring. These MMTV-rtTA mice are a Tet-On tool that allows conditional, dox-inducible expression of genes primarily in mammary gland epithelial cells and may be useful in studying the endocrine function of mammary tissues and/or breast cancer (for example).

Development
The MMTV-rtTA-SV40 transgene was designed with the 1.5 kb mouse mammary tumor virus long terminal repeat (MMTV-LTR) promoter, the reverse tetracycline transactivator gene and VP16 activation domain (rtTA-VP16), and SV40 intron/polyA sequence. The rtTA-VP16-polyA sequence is inserted into exon 3 of the rabbit beta-globin gene immediately following the MMTV promoter. This 3.75 kb transgene was injected into one-cell (C57BL/6 x SJL) mouse zygotes. Mice from founder line 4-1 were bred with C57BL/6;SJL wildtype mice to establish the colony. The donating investigator reports that MMTV-rtTA transgenic mice were bred together, to wildtype siblings, and/or to tetO-transgenic mice (on the same mixed C57BL/6;SJL genetic background) for many generations. Mice harboring only the MMTV-rtTA transgene were then sent to The Jackson Laboratory. Upon arrival, transgenic mice were bred with B6SJLF1/J hybrid mice (Stock No. 100012) for at least one generation to establish this colony.

Allele Symbol Tg(MMTV-rtTA)4-1Jek
Allele Name transgene insertion 4-1, Jeffrey E Kudlow
Allele Type Transgenic (Inserted expressed sequence)
Common Name(s) MMTV-rtTA; MMTV-rtTA-SV40;
Mutation Made By Jeffrey Kudlow,   University of Alabama at Birmingham
Strain of Origin(C57BL/6 x SJL)
Site of ExpressionExpression of the reverse tetracycline-controlled transactivator (rtTA) protein is directed primarily to the breast epithelia of the mammary ductal system by the mouse mammary tumor virus (MMTV) promoter. The donating investigator also reports some rtTA expression in salivary glands (particularly in the males) as well as prostate glands
Expressed Gene rtTA, reverse tetracycline-controlled transactivator, E. coli
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).
Promoter MMTV, Mouse Mammary Tumor Virus, MMTV
Molecular Note The MMTV-rtTA-SV40 transgene was designed with the 1.5 kb mouse mammary tumor virus long terminal repeat (MMTV-LTR) promoter, the reverse tetracycline transactivator gene and VP16 activation domain (rtTA-VP16), and SV40 intron/polyA sequence. The rtTA-VP16-polyA sequence is inserted into exon 3 of the rabbit beta-globin gene immediately following the MMTV promoter. This 3.75 kb transgene was injected into one-cell (C57BL/6 x SJL) mouse zygotes. Mice from founder line 4-1 were bred with C57BL/6;SJL wildtype mice to establish the colony.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
