Homozygotes develop normally, are fertile and have a normal life span. 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.

These Plau knock-out mice exhibit occasional fibrin deposition and excessive fibrin deposition when combined with the Plat knock-out. They are suitable for use in applications related to the study of the fibrinolytic system.

Typically mice are recovered in 12-16 weeks. Contact Customer Service to place an order or for more information.
