Homozygotes develop normally, have a normal life span, and are poor breeders. Pups often need fostering. Rectal prolapse of a non-infectious origin develops in 9% of homozygotes and/or extensive non-healing ulcerations occur at the eyelids and around the face. Small, focal fibrin deposits are occasionally seen in the intestines and in the sinusoids of the liver, and excessive fibrin deposits are seen in ulcerated skin or prolapsed rectum. Pulmonary clot lysis is comparable to that seen in normal wildtype siblings. Endotoxin induced venous thrombosis is increased over normal wildtype siblings. Fibrin dissolution by PLAU-deficient macrophages is greatly reduced but macrophage invasion into the peritoneal cavity after thioglycollate injection is unaffected. Homozygous knockout mice have increased levels of Abeta42 and Abeta40 in plasma. Brain Abeta levels are not significantly different than controls.
In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
This targeted mutant was made in the laboratories of Dr. Richard Mulligan of the Whitehead Institute for Biomedical Sciences, Cambridge Massachusetts and of Dr. Peter Carmellet at the Center for Molecular and Vascular Biology, University of Leuven, Leuven, Belgium. A targeting vector was used which resulted in the neomycin-resistant gene (neo) replacing all but 23 amino acids of the coding sequence. Targeting was done in 129S2/SvPas-derived D3 ES cells.

Strain of Origin | 129S2/SvPas |
Chromosome | 14 |
Molecular Note | The gene was disrupted using neomycin resistance cassette. The vector replaced genomic sequences encompassing all but 23 amino acids of the coding sequence. Targeting was confirmed by the absence of gene specific mRNA and immunoreactivity. |

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
