Genetic Alterations

ENU-induced T to C transition at position 863 of the Atp4a transcript (NM_018731) in exon 7 of 22 total exons.  The mutation results in a serine to proline change at position 282 of the encoded gastric H,K-ATPase subunit.

Phenotype
Sublytic homozygotes are severely anemic, with low hemoglobin due to a reduced hematocrit and to reduced hemoglobin content per red blood cell (RBC); there is no reduction in mean corpuscular volume of RBCs. Development of anemia is independent of the hematopoietic compartment. This phenotype has not been described for Atp4a-/- mice.
Erythrocytes from sublytic homozygotes are more resistant to lysis in saline than those of wild-type mice, requiring a salt concentration about 30% more dilute to lyse half the cells relative to wild type. Sublytic homozygotes display increased hematopoiesis, and increased numbers of reticulocytes compared to wild-type mice. Blood from sublytic homozygotes contains a lower frequency of leukocytes, but normal frequencies of NK cells, T cells, and B cells.
Homozygous sublytic mice develop hard, enlarged stomachs with cysts in gastric glands as seen in histological sections.

Heterozygous mice are normal.

Strain Development

Original mutant was a C57BL/6J G3 ENU-induced mutant; all subsequent crosses to maintain strain were on C57BL/6J background only.

Suggested Control Mice
Wild-type littermates, C57BL/6J

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.
