Genetic Alterations
Mice carrying a knockout-first conditional-ready allele for Hira (Hiratm1a(EUCOMM)Wtsi) were obtained from the European Conditional Mouse Mutagenesis Program (EUCOMM) at the Wellcome Trust Sanger Institute (White et al., 2013). These mice were crossed to ROSA26-Flpe mice (Gt(ROSA)26Sor-tm1(FLP1)Dym) (Farley et al., 2000) that express Flp recombinase ubiquitously to delete the promoterless LacZ cassette, while leaving behind exon 4 flanked by two loxP sites.
Genotype Determination
ES Cell Line
JM8N4
Phenotype

Homozygous: Viable, fertile, no abnormal defects.

Heterozygous: Viable, fertile, no abnormal defects.

Cre-excised Phenotype: Deletion of the gene with Zp3-Cre mice (Tg(Zp3-cre)93Knw) (de Vries et al., 2000) that express Cre recombinase in the female germline will result in a failure of male pronucleus formation in the zygote, and zygotes fail to progress to the 2-cell stage. (Lin et al, 2014)

Maternal Hira is essential for mouse zygote development to the two-cell stage.

Strain Development
Mice carrying a knockout-first conditional-ready allele for Hira (Hira-tm1a(EUCOMM)Wtsi) were obtained from the European Conditional Mouse Mutagenesis Program (EUCOMM) at the Wellcome Trust Sanger Institute (White et al., 2013). The genetic background as declared by Sanger is C57BL/6NTac;C57BL/6NTac;C57BL/6N. http://www.sanger.ac.uk/mouseportal/search?query=MGI:99430 We crossed these mice to ROSA26-Flpe mice (Gt(ROSA)26Sor-tm1(FLP1)Dym) (Farley et al., 2000) that express Flp recombinase ubiquitously to delete the promoterless LacZ cassette, while leaving behind exon 4 flanked by two loxP sites. The ROSA26-Flpe mice have a C57BL/6J background. The resulting Hira-tm1c(EUCOMM)Wtsi (Hira-flox) mice were bred to homozygosity and maintained via sibling breedings for the last 2 years.

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@ucdavis.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.

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.
