On the basis of evidence that within the adult kidney, the aldo-keto reductase AKR1B7 (aldo-keto reductase family 1, member 7, also known as mouse vas deferens protein, MVDP) is selectively expressed in renin-producing cells, we aimed to define a possible role of AKR1B7 for the regulation and function of renin cells in the kidney. We could confirm colocalization and corecruitment of renin and of AKR1B7 in wild-type kidneys. Renin cells in AKR1B7-deficient kidneys showed normal morphology, numbers, and intrarenal distribution. Plasma renin concentration (PRC) and renin mRNA levels of AKR1B7-deficient mice were normal at standard chow and were lowered by a high-salt diet directly comparable to wild-type mice. Treatment with a low-salt diet in combination with an angiotensin-converting enzyme inhibitor strongly increased PRC and renin mRNA in a similar fashion both in AKR1B7-deficient and wild-type mice. Under this condition, we also observed a strong retrograde recruitment of renin-expressing cell along the preglomerular vessels, however, without a difference between AKR1B7-deficient and wild-type mice. The isolated perfused mouse kidney model was used to study the acute regulation of renin secretion by ANG II and by perfusion pressure. Regarding these parameters, no differences were observed between AKR1B7-deficient and wild-type kidneys. In summary, our data suggest that AKR1B7 is not of major relevance for the regulation of renin production and secretion in spite of its striking coregulation with renin expression.
