Strain Information

Type Mutant Stock; Targeted Mutation;
Mating SystemHeterozygote x Homozygote         (Female x Male)
Specieslaboratory mouse
GenerationN1+F3 (08-JAN-08)
 
Donating Investigator Jay Horton,   Univ of Texas SW Med Center at Dallas

Description
Homozygous mice are viable and fertile with no behavioral abnormalities. No expression of the endogenous RNA or protein is observed in liver. Homozygotes have reduced plasma cholesterol levels; apolipoprotein B (apoB)-containing low-density liproprotein (LDL) is nearly undetectable and apolipoprotein E (apoE)-containing high density liproprotein (HDL) levels are reduced 30%. Homozygotes show increased hepatic LDL-receptor (LDLR) protein (but not RNA) expression. Homogygous mice also have accelerated clearance of circulating cholesterol. Lovastatin addition to the diet of homozygous mice results in further increased hepatic LDLR and LDL clearance from the blood. Heterozygous mice have intermediate plasma cholesterol and LDL clearance. This mouse may be useful in studies of lipid homeostasis, cholesterol metabolism, apolipoprotein function, and statin treatment for hypercholesterolemia.

Development
A targeting vector was designed to replace the region spanning from the C-terminal region of exon 2 through exon 4 of the endogenous gene with a neomycin resistance cassette. The construct was electroporated into 129S6/SvEvTac-derived SM-1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts. The resulting chimeric males were bred to C57BL/6J females. Heterozygous offspring were crossed to generate homozygous mice.

The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.

Pcsk9tm1Jdh/Pcsk9tm1Jdh

        involves: 129S6/SvEvTac
  • homeostasis/metabolism phenotype
  • decreased circulating cholesterol level (MGI Ref ID J:97836)
    • plasma cholesterol levels were 48% lower than in wildtype, despite similar levels of plasma triglycerides
    • plasma cholesterol levels decreased even more with the addition of lovastatin to the diet
    • decreased circulating HDL cholesterol level (MGI Ref ID J:97836)
      • 30% reduction in plasma HDL cholesterol levels
    • decreased circulating LDL cholesterol level (MGI Ref ID J:97836)
      • nearly undetectable levels of plasma LDL cholesterol levels
      • 5-fold increase in the rate of labeled LDL cholesterol clearance from plasma (12 min to clear 50% of LDL versus more than 60 min in wildtype)
      • additional 2-fold increase in the rate of labeled LDL cholesterol clearance from plasma when lovastatin was added to the diet

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
