    Strain Description

    Phenotype
    RGS12 loss significantly decreases hyperlocomotion to low doses of both amphetamine and cocaine; however, other outcomes of administration (sensitization and conditioned place preference) are unaffected. Phenotypes are only elaborated when Cre-recombinase is cross-bred and expressed (or induced).
    Strain Development
    Conditional knockout of the Rgs12 gene was produced directly in the C57BL/6 background by genOway (Lyon, France). It involved insertion of loxP sites on either side of Rgs12 exons 5 and 6, as well as a neomycin-resistance gene (neo) flanked by “flippase recognition target” (FRT) sites, by homologous recombination in C57BL/6 embryonic stem cells. Drug-selected embryonic stem cells, with PCR and Southern blot evidence of homologous recombination, were subsequently injected into C57BL/6 blastocysts. Resulting chimeric male mice were crossed with females from the genOway proprietary ubiquitous Flp recombinase expressing mice for in vivo removal of the FRT-flanked neo selection cassette. F1 heterozygous Rgs12fl/+ mice devoid of the neo selection cassette were delivered by genOway to the Siderovski lab at WVU. This conditional ‘floxed’ Rgs12 knockout strain was maintained at WVU by backcrossing to the C57BL/6J strain.
    Suggested Control Mice
    C57BL/6J or Wild-type littermate

    MMRRC Genetic QC

    MMRRC Genetic QC Summary
    Genetic QC analysis (GQC) was performed on representative samples from the donor submission and provides a baseline reference. Regardless of the material ordered (live mice, sperm, embryos, resuscitated animals), the provided material is guaranteed to contain the primary genetic alteration of interest; however, the composition of the genetic background may vary (See Reproducibility sections of the report for details). The impact of genetic background on previously reported phenotypes has not been evaluated.

    GQC analysis was done on two samples MA1094 (XY), WU0180 (XX) at the time of importation and the conclusions are consistent in all samples. The results of the analysis are congruent with the SDS and MA1094 is the representative sample selected for the report. The primary (host) background is C57BL/6 and there is positive evidence of the, C57BL/6J and C57BL/6N substrains. The mitochondrial genome is consistent with the C57BL/6 background and the Y chromosome is consistent with at least one backcross to C57BL/6J. Both samples are homozygous for the C57BL/6N background at the locus. The following construct(s) is/are detected in all samples: bpA, Flp, hCMV_a, hCMV_b, IRES.

    The genome of MMRRC:046281 mice is 83.9% inbred at the substrain level 16.1% of the genome is segregating for the two substrains,C57BL/6J and C57BL/6N. The contribution of C57BL/6J is 69.8%. The contribution of C57BL/6N is 30.2%.

    The estimated inbreeding, congenicity, and the relative strain/substrain contribution depend on the number of samples genotyped. The genomes of strains that are not fully inbred are not completely reproducible.

    Order Request Information

    Availability Level

    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.

    Conditions of Distribution

    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.

    Fees

    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.
