These mice carry a knockout of the Rnls (renalase, FAD-dependent amine oxidase) gene. Homozygotes exhibit increased plasma catecholamine levels, hypertension, and mild ventricular hypertrophy in the absence of any measurable change in renal function.

Targeted (Null/Knockout) | Rnls | renalase, FAD-dependent amine oxidase |
The Rnls (renalase, FAD-dependent amine oxidase) gene encodes an oxidase that metabolizes catecholamines. It is expressed in kidney, heart, and skeletal muscle and secreted into the blood by the kidney. Levels of the protein are decreased in patients with chronic kidney disease (CKD) and end-stage renal disease.
These mice carry a knockout allele of the gene. Homozygotes demonstrate increased plasma catecholamine levels, hypertension, and mild ventricular hypertrophy in the absence of any measurable change in renal function. They tolerate cardiac ischemia poorly and develop myocardial necrosis threefold more severe than wildtype controls. This gene plays and important role in cardiovascular pathology.
Interestingly, in xenograft mouse models it has been shown that using a renalase monoclonal antibody shRNA knockdown of renalase inhibits pancreatic ductal adenocarcinoma growth.
Exons 1-4 were replaced by a neomycin resistance cassette, deleting the promoter and a large part of the coding region. The mutation was created in 129S1/Sv-Oca2+Tyr+Kitl+-derived W9.5 embryonic stem (ES) cells. Resultant chimeric males were bred to C57BL/6 females. This strain was maintained on a mixed C57BL/6 and 129S1 genetic background by the donating lab. Gene disruption was confirmed by genomic Southern blot, PCR, and western blot.

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.
