The mechanism of its formation is unknown. Possibly, enhanced delivery of calcium out of the proximal tubule, found in many stone formers, increases reabsorption of calcium from the thick ascending limb into the interstitium around descending vasa recta, which convey that calcium into the deep medulla, and raises supersaturations near thin limbs (\u201cvas washdown\u201d). According to this hypothesis, plaque should form preferentially on ascending thin limbs, which do not reabsorb water. We stained serial sections of papillary biopsies from stone-forming patients for aquaporin 1 (which is found in the descending thin limb) and the kidney-specific chloride channel ClC-Ka (which is found in the ascending thin limb). Plaque (which is detected using Yasue stain) colocalized with ClC-Ka, but not with aquaporin 1 (\u03c7<jats:sup>2<\/jats:sup>\u2009=\u2009464, P &lt; 0.001). We conclude that plaque forms preferentially in the basement membranes of ascending thin limbs, fulfilling a critical prediction of the vas washdown theory of plaque pathogenesis. The clinical implication is that treatments such as a low-sodium diet or thiazide diuretics that raise proximal tubule calcium reabsorption may reduce formation of plaque as well as calcium kidney stones.<\/jats:p>","DOI":"10.1152\/ajprenal.00035.2018","type":"journal-article","created":{"date-parts":[[2018,8,1]],"date-time":"2018-08-01T11:35:04Z","timestamp":1533123304000},"page":"F1236-F1242","source":"Crossref","is-referenced-by-count":46,"title":["Randall\u2019s plaque in stone formers originates in ascending thin limbs"],"prefix":"10.1152","volume":"315","author":[{"given":"Andrew P.","family":"Evan","sequence":"first","affiliation":[{"name":"Department of Anatomy and Cell Biology, Indiana University School of Medicine, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fredric L.","family":"Coe","sequence":"additional","affiliation":[{"name":"Nephrology Section, Department of Medicine, University of Chicago, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Lingeman","sequence":"additional","affiliation":[{"name":"Department of Urology, Indiana University School of Medicine, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Bledsoe","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Cell Biology, Indiana University School of Medicine, Indianapolis, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elaine M.","family":"Worcester","sequence":"additional","affiliation":[{"name":"Nephrology Section, Department of Medicine, University of Chicago, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1980.239.1.F24"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1007\/s00240-010-0296-z"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1038\/nrneph.2016.101"},{"key":"B4","first-page":"472","volume":"37","author":"Deganello S","year":"1990","journal-title":"Kidney Int"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1002\/ar.20580"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1172\/JCI17038"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1002\/ar.22881"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1002\/ar.23105"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1136\/jclinpath-2017-204387"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1007\/s00240-014-0705-9"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.00071.2015"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2003.00316.x"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1989.257.5.F738"},{"key":"B14","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1681\/ASN.V811","volume":"8","author":"Maunsbach AB","year":"1997","journal-title":"J Am Soc Nephrol"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1111\/jcmm.12514"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1007\/s00240-014-0718-4"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1172\/JCI117626"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.00236.2015"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(17)47703-2"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.90404.2008"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1369\/0022155411398488"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1267\/ahc.2.83"}],"container-title":["American Journal of Physiology-Renal Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/ajprenal.00035.2018","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,8,28]],"date-time":"2022-08-28T15:35:17Z","timestamp":1661700917000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/ajprenal.00035.2018"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,11,1]]},"references-count":22,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2018,11,1]]}},"alternative-id":["10.1152\/ajprenal.00035.2018"],"URL":"https:\/\/doi.org\/10.1152\/ajprenal.00035.2018","relation":{},"ISSN":["1931-857X","1522-1466"],"issn-type":[{"value":"1931-857X","type":"print"},{"value":"1522-1466","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,11,1]]}}}
