Genetic Alterations
This knock-out allele of Tbx3 (T-box 3) carries a deletion of most of the DNA binding T box domain, resulting in embryonic lethality. Homozygous mutant embryos exhibit three major abnormalities: yolk sac cell degeneration, a deficiency of mammary gland induction, and limb defects. This strain may be useful for studying ulnar-mammary syndrome.
Genotype Determination
ES Cell Line
R1
Phenotype
The Tbx3 (T-box 3) gene belongs to a family of transcription factors involved in development. Mutations in this gene are associated with ulnar-mammary syndrome and human breast cancer. Exons 2, 2a, and 3, representing most of the DNA binding T-box domain, are deleted in this knock-out allele. Homozygous mutant embryos exhibit three major abnormalities: yolk sac cell death and degeneration at midgestation, a deficiency of mammary gland induction, and forelimb and hindlimb defects. Half of the embryos are dead by E11.5, none survive beyond E16.5(yolk sac apoptosis MP:0001718, failure of mammary gland induction MP:0004135, limb abnormalities MP:0002109, cardiovascular abnormalities MP:0002925, pharyngeal abnormalities MP:0002234.)

Heterozygote mice do not exhibit limb or mammary gland defects, but do exhibit alterations to external genitalia, including a ventral split in the glans clitoris and a distal bifurcation of the prepuce. In a small number of females, the vagina fails to open. These mice may be useful for studying ulnar-mammary syndrome.(deficient mammary gland development MP:0003344 in conjunction with mutations in Tbx2; external genitalia abnormalities in females (bifurcated glans clitoris) MP:0003126).

Strain Development
The targeting vector was designed to use a loxP-flanked selection cassette containing HSV-TK and the neomycin resistance gene to delete exons 2, 2a, and 3. These exons encode 158 amino acids of the DNA binding T-box domain. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were transiently transfected with a pIC-Cre expression plasmid to delete the neo cassette. The resulting ES cells, with excision of exons 2-3 and the neo cassette, were injected into blastocysts. The resulting chimeric animals were crossed to C57BL/6Tac females. Mice were later crossed to ICR (Taconic) and Swiss Webster(Taconic) outbred mice. The strain was then maintained by sibling mating. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.

Colony and Husbandry Information

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email csmmrrc@jax.org.

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 csmmrrc@jax.org 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.

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.
