Synonyms: CAG-NAG-1, NAGTg+
Type: Transgene
Species: Mus musculus (mouse)
Chromosome: unknown
Alteration at locus: Transgenic
Genetic Alterations
The human NAG-1 cDNA34 was cloned into the plasmid pCAG-LoxP/CAT/LoxP35 to generate a transgene vector pCAG-LoxP/CAT/LoxP-NAG-1. Transgenic mice were generated that ubiquitously overexpress human NAG-1 under the control of a chicken Beta-actin promoter (CAG).
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • Phenotype

    Homozygous: Not evaluated

    Hemizygous: NAG-(Tg+) mice showed no apparent phenotype other than a reduction in body weight, particularly in males. When treated with the colorectal carcinogen azoxymethane, NAG-(Tg+) mice developed 50% fewer aberrant crypt foci and no tumors, in comparison with nontransgenic littermates.

    Strain Development
    Transgenic mice on the C57BL/6 background were created using standard microinjection procedures. Transgenic founder lines (founder line numbers 1377 and 1398) were identified and characterized for CAG-directed CAT expression. Mice were bred to protamine-Cre transgenic mice (C57BL/6 background). Male Protamine Cre:CAG-LoxP-CAT/LoxP-NAG-1 compound transgenic mice were bred to female C57BL/6 mice to generate offspring that had deleted the floxed CAT reporter, which turned on expression of the NAG-1 gene. Mice were backcrossed to C57BL/6 for many generations.

    Order Request Information

    Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

    The donor or their institution limits the distribution to non-profit institutions only.

    Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

    041468-UNC-RESUS Litter recovered from cryo-archive $2,914.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

    2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

    3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

    4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
