Abstract excerpt
Urea transporter UT-A2, the major urea transporter of the thin descending limb of the loop of Henle in short loop nephrons, has been implicated in urea recycling in the medulla, thereby producing concentrated urine. To investigate the physiological role of UT-A2 in vivo, we generated UT-A2-selective knockout mice by deleting the UT-A2 promoter. Western analysis, immunohistochemistry, and quantitative reverse...
