These Plaur knock-out mice exhibit no overt phenotypic abnormalities with no compromise in fertility, development, or hemostasis.
Dr. Thomas Bugge, NIH/NIDCR
Homozygous mice are born and survive to adulthood with no overt phenotypic abnormalities. No Plaur gene product (protein) is detected. In addition, activated peritoneal macrophages collected from homozygous mice fail to promote plasminogen activation in vitro. The loss of the receptor also results in a redistribution of uPA in some tissues but has no impact on pro-PLAU activation in the urogenital tract. Thus, in the absence of other challenging factors such as infection, injury, or other functional deficits, PLAUR deficiency does not compromise fertility, development, or hemostasis. These mice provide a means to test the proposed function of PLAU/PLAUR in wound repair, atherogenesis, and tumor cell invasion in vivo.
This mutation was generated by replacing exon 3 with a vector containing Hprt. The 129P2-derived E14TG2a ES cell line was used. Strain records suggest it was backcrossed to C57BL/6 for at least 10 generations prior to freezing at The Jackson Laboratory in 2002. While maintaining this strain (restocking frozen materials) at The Jackson Laboratory, at least one additional backcross to C57BL/6J has been performed.
