Genetic Alterations
This strain harbors a floxed exon 3 of the Evi1 gene, one of several isoforms of the Mecom locus. In the floxed (undeleted) state, there is no phenotype. With deletion, exon 3 (harboring the initiator methionine) is lost, resulting in complete loss of the Mds1-Evi1 isoform (also known as PRDM3), and generation of a hypomorphic Evi1 allele. The EVI1 protein is still produced in the homozygous deleted state, due to an alternative initiator methionine in exon 4.The neo selection cassette was removed in vitro.

    Phenotype

    The conditional-ready (floxed model) has no phenotype.

    Conditional phenotype: Homozygous deleted mice show perinatal lethality due to a cardiac defect (described in PMID:24586749); fetal livers show a significant reduction in KSL stem/progenitors; newborns show mild leukopenia and thrombocytopenia; and specific deletion in the hematopoietic cells results in bone marrow failure, with complete marrow aplasia and markedly severe peripheral cytopenias and death.
    Strain Development

    LoxP sites were inserted on either side of the first exon coding for the EVI1 protein isoforms (exon containing the initiator methionine). These were inserted via homologous recombination in S1B6A embryonic stem cells derived from
    (129S1/SvImJ x C57BL/6J)F1. The neo cassette was deleted in vitro through transient expression of a Cre vector. Positive clones were identified by Southern blot analysis. One of these was chosen and inserted into blastocyst cavities for the development of mice. Subsequent backcrossing to C57BL/6J (N20+) and sib-mating (F20+).

    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.

    068164-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.
