Genetic Alterations
The Tshb-cre transgene was generated by recombineering a mouse Tshb BAC from a male C57BL/6 library (RP24-230F23, Roswell Park Institute) The Tshb-containing BAC included: 144 kb of 5'-flanking region, all five exons, with intervening introns, and 40 kb of 3'-flanking region. In the murine Tshb gene, the first three exons are noncoding and contain an alternate splice site, whereas exons 4 and 5 encode the complete protein. In the recombineered BAC, the coding region of Tshb was substituted for nuclear localization signal (NLS)-cre-actin, using an NLS-cre-actin cassette, flanked by approximately 50 nucleotides 5'- and 3'-homology arms of Tshb immediately upstream and downstream of the initiation and termination codons, respectively.
Genotype Determination
ES Cell Line
Not applicable
Phenotype

None/Normal/Wild-type

Conditional phenotype: Mild hypothyroidism when crossed with pituitary-specific cre transgenic line.

Strain Development
The transgenic founders carrying the Tshb-cre BAC were generated by microinjecting (C57BL/6 x SJL)F1 x F1 fertilized eggs and transferring them to surrogate mothers. Four transgenic founders were identified and bred to C57BL/6J mice for further characterization. Line #4 was identified with the highest level of specific expression and expanded by breeding to C57BL/6J mice. The colony was then backcrossed to C57BL/6J mice (RRID:IMSR_JAX:000664) for at least 10 generations (N10).

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact csmmrrc@jax.org. Older strains may not have this information.

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.

A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact John Corthell.

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.

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.
