Genetic Alterations

This mouse line was modified by homologous recombination at the Ace2 locus. The regulatory region and coding region of the mouse Ace2 gene was removed and replaced by the regulatory and coding regions of the human ACE2 gene.

Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    129Sv derived from 129S2/SvPas
    Phenotype
    This mouse expresses the human ACE2 gene and protein/transmembrane enzyme under the control of the human ACE2 promoter. The expression pattern of the human ACE2 gene/protein has been extensively detailed and compared to the expression pattern of the mouse Ace2 gene/protein. As much as possible, the expression of the humanized locus has been compared to that reported for human tissue/cell lines. Sex specific differences in expression have also been detailed, as well as expression of human ACE2 splice variants. Tissues evaluated for expression of the humanized locus include airways, heart, kidney and gastrointestinal system .

    This mouse line carries an Ace2 allele identical to that described in MMRRC:69710 (129S6/SvEvTac-Ace2tm2(ACE2)Bhk/Mmnc) and MMRRC:69714 (CBy.129S6/SvEvTac-Ace2tm2(ACE2)Bhk/Mmnc). The primary difference is that this strain is on a mostly C57BL/6N genetic background.
    Strain Development
    The Ace2 displacer constructs were assembled using a standard recombineering approach. The mouse arms of homology were derived from the 129S7/AB2.2 bMQ BAC library clone bMQ306a09 (Source BioScience). The segment of human genomic DNA containing the ACE2 gene was derived from the human tile path BAC RP11-478H11 (BACPAC Resources). The resistance marker gene used for selection of embryonic stem (ES) cells in which the Displacer construct underwent genomic integration consisted of a PGK-neo cassette flanked by mutant loxP sites. Excision of the marker gene with transient expression of Cre leaves a nonfunctional lox site in its place. The recombination events for generation of both lines were carried out in the 129S6 ES cell line, Phnx43. ES cells carrying the correctly modified locus were used to generate chimeric mice, which were bred to C57BL/6NCrl (Charles River Laboratories) mice.

    Order Request Information

    Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at mmrrc@med.unc.edu for more details.

    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.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 Carmen Melvin.

    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.
