Specieslaboratory mouse
GenerationF?+2+N1p (07-MAR-04)
 
Donating Investigator Harold Varmus,   Memorial Sloan-Kettering Cancer Center

Description
Mice that are homozygous for the transgene are viable and fertile. These transgenic mice express activated rat Kras (Kras4bG12D) under the regulation of a tetracycline-responsive promoter element (TRE; tetO). When these mice are mated to strains containing transgenes encoding either rtTA (reverse tetracycline trans-activator protein) or tTA (the tetracycline trans-activator), activated Kras expression in the bitransgenic animals can be induced by administration or withdrawl, respectively, of the tetracycline analog, doxycycline. This strain represents an effective tool for generating tissue specific mutants that would be useful models for studying oncogene activation in human carcinogenesis.

Development
A transgenic construct containing the mutant gene (Kras4bG12D) under the regulation of a tetracycline-responsive promoter element (TRE; tetO), the mp-1 intron and polyadenylation site sequence, and a minimal CMV promoter was injected into FVB/N blastocysts.

Genes & Alleles

Gene & Allele Information

Allele Symbol Tg(tetO-Kras2)12Hev
Allele Name transgene insertion 12, Harold E Varmus
Allele Type Transgenic (random, expressed)
Common Name(s) K-Ras4b responder; K-Ras4bG12D responder; K-ras4bG12D; K-rasG12D-5; KE; TOR; Tet-op-K-RasG12D; Tet-op-K-ras; TetO-KrasG12D; tre-Kras;
Mutation Made By Harold Varmus,   Memorial Sloan-Kettering Cancer Center
Strain of OriginFVB/N
Expressed Gene Kras, v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog, rat
Promoter CMV, cytomegalovirus, human
General Note Homozygous transgenic mice are viable and fertile. In conjunction with a second transgene encoding either rtTA (reverse tetracycline trans-activator protein) or tTA (the tetracycline trans-activator), mice carrying Tg(tetO-Kras2)12Hev show tissue-specific expression of the mutated K-ras transgene that may be induced or suppressed by administration of the tetracycline analog, doxycycline. Cessation or initiation of doxycycline treatment in bitransgenic strains containing, respectively, rtTA or tTA, will result in a rapid decrease of expression of the transgene.
Molecular Note The transgene expresses the mutant gene Kras4bG12D, under the control of a tetracycline-responsive promoter element (tTA), mp-1 intron polyadenylation site sequence, and a minimal CMV promoter. [MGI Ref ID J:73468]

Supply Notes
  • Cryorecovery - Standard.
    The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery.

    Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
    One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845.

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.
