Strain Information

Hfe
Name: homeostatic iron regulator
Synonyms: MR2
Type: Gene
Species: Mouse
Chromosome: 13
NCBI: 15216
HGNC: HGNC:4886
Homologene: 88330
Ttr
Name: transthyretin

Genetic Alterations
Mouse Hfe is overexpressed as a transgene under the control of the Ttr promoter. The final 15 amino acids of the protein were removed and replaced with a cMyc epitope tag.
Genotype Determination
Phenotype

Homozygous: Not evaluated.

Heterozygous: The mice have a hypochromic and microcytic anemia. They display decreased serum and liver iron and elevated hepcidin expression.

Strain Development
Correctly targeted constructs were microinjected into C57BL/6NCrl oocyte pronuclei. Hemizygous C57BL/6J male transgenic animals were then bred to wild-type C57BL/6J females.
Suggested Control Mice
Wild-type littermates
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@ucdavis.edu. Older strains may not have this information.

Schmidt PJ, Andrews NC, Fleming MD. Hepcidin induction by transgenic overexpression of Hfe does not require the Hfe cytoplasmic tail, but does require hemojuvelin. Blood. 2010 Dec 16;116(25):5679-87. (Medline PMID: 20837779).

Colony and Husbandry Information

Female transgenics are poor breeders.

Colony Surveillance Program and Current Health Reports

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@ucdavis.edu.
Coat Color
Black
Other
Animals carrying the trasngene tend to have alopecia because of their anemia. This tends to be more pronounced in males.
MMRRC Breeding System
Backcross
Breeding Scheme(s)
  • Wild-type (C57BL/6J) female x Hemizygous male
    • Female animals carrying the transgene are anemic and do not reproduce well.
    • Males carrying the transgene reproduce well. Breeding transgenic males to wild-type females for optimal litter number.
Generation
N10+
Overall Breeding Performance
Excellent when bred as listed in Breeding Schemes.
NOTE: "Hemizygote" as used here refers to males carrying a mutation on the X Chromosome or mice of either sex carrying an inserted transgene with no homologous allele on the other chromosome.
Viability and Fertility: Female Male Comments
Homozygotes are viable: Undetermined Undetermined
Homozygotes are fertile: Undetermined Undetermined
Hetero/Hemizygotes are fertile: Reduced Yes
Age Reproductive Decline: Undetermined Undetermined

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.
