Upp1
Name: uridine phosphorylase 1

Genetic Alterations
The targeting construct contains the Upp1 coding sequence driven by the CAGGS promoter, a hybrid chicken β-actin and cytomegalovirus promoter. The promoter and Upp1 coding sequence were interposed by a neomycin resistance cassette, which was flanked by loxP sites on the targeted ROSA26 locus. Cre-mediated recombination removed the floxed neomycin cassette inserted downstream of the CAGGS promoter.
Genotype Determination
ES Cell Line
Not specified
Phenotype

Homozygous: Not characterized.

Heterozygous: Not characterized.

Cre-excised Phenotype: UPase enzymatic activity in the liver tissue of Upp1-TG mice is 25-fold higher than that of wild-type mice. The liver uridine level of Upp1-TG mice is 13-fold lower than that of wild-type mice. The liver β-alanine level, which was the product of uridine catabolism, is more than 2-fold higher in Upp1-TG mice compared with wild-type mice. Overall, plasma and tissue uridine levels are markedly lower in Upp1-TG mice compared with wild-type mice. Thus, ubiquitous overexpression of Upp1 in Upp1-TG mice causes depletion of endogenous plasma and tissue uridine.

Allelic Composition: Gt(ROSA)26Sortm1.1(CAG-Upp1)Gp/Gt(ROSA)26Sor+ (Genetic Background: involves: FVB/N )

Strain Development
Gene expression “knock-in” was achieved by crossing these transgenic mice with FVB/N-Tg(ACTB-cre)2Mrt/J mice, expressing Cre-recombinase in the desired tissue, which excised the loxP sites and released a neomycin resistance cassette allowing CAGGS-driven expression of Upp1. Cre expression was driven by the ubiquitous β-actin promoter. Mice were then backcrossed on C57BL/6 for more than 8 generations.
Suggested Control Mice
Wild-type littermates or C57BL/6 mice
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.

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.

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.

Litter Recovered litter4; additional fees for any special requests.

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.
