Genetic Alterations

Easi-CRISPR-mediated insertion of P2A (self-cleaving peptide) fused to codon-optimized Cre into the Slc26a9 stop codon.

Not applicable
Phenotype
Animals express Cre under the control of the Slc26a9 promoter while maintaining normal expression of Slc26a9. The donor characterized the patterns of CRE activity but did not explicitly test for any of the previously published Slc26a9 null phenotypes (e.g. abnormal secretion of gastric acid). Homozygotes of both sexes have normal fertility and no obvious abnormalities. Females apparently express CRE activity in the germline as their offspring may show ubiquitous expression of CRE-dependent reporters. In the offspring of male carriers, CRE activity is evident in otic placode derivatives (the inner ear epithelium and neurons), but unlike other pan-otic Cre-drivers, there is no CRE activity in auditory or vestibular brain nuclei. This allows the strain to be used to manipulate genes in the inner ear/otic neurons without affecting the brain. The donor furthermore noted CRE activity in many FGFR2b-dependent epithelia (lung, stomach, pancreas, pituitary), so the strain may be useful for gene manipulation in those tissues as well (PMID:32541002).
Note: Transmission of the allele through female carriers gives widespread recombination, whereas transmission from males gives the specific pattern recombination patterns documented in the original publication.
Strain Development

Easi-CRISPR was used to generate founders in the C57BL/6J background. Two correctly targeted female founders (6 and 7) were crossed to C57BL/6J males to transmit the new allele. Subsequent cross to 129S6/SvEvTac.

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 mmrrc@missouri.edu. Older strains may not have this information.

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@missouri.edu 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 Eric Paulsen.

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.

Litter Recovered litter4; additional fees for any special requests.

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.
