Urea transporter knockout mice and their renal phenotypes.
Fenton RA, Yang B. Fenton RA, et al. Subcell Biochem. 2014;73:137-52. doi: 10.1007/978-94-017-9343-8_9. Subcell Biochem. 2014. PMID: 25298343 Review.
The major findings in studies of the renal phenotype of these mice are as follows: (1) Urea accumulation in the inner medullary interstitium is dependent on intrarenal urea recycling mediated by urea transporters; (2) urea transporters are essential fo …
