Despite identification of the genes responsible for ADPKD, few effective drugs are currently available for the disease. Thus finding additional effective drug targets is necessary. The functions of multidrug- resistance-associated protein 3 (MRP3) have been reported only in the field of drug resistance, and the renal functions of MRP3 are mostly unknown. In this study, we found that MRP3 was significantly downregulated in kidneys of human patients with ADPKD and polycystic kidney disease (PKD) mouse models. Our results suggest that downregulated MRP3 stimulated renal epithelial cell proliferation through the B-Raf\/MEK\/ERK signaling pathway. In contrast, we found that restoring MRP3 reduced cell proliferation and cystogenesis in vitro. These results suggest that the renal function of MRP3 is related to renal cell proliferation and cyst formation and that restoring MRP3 may be an effective therapeutic approach for PKD. <\/jats:p>","DOI":"10.1152\/ajprenal.00159.2014","type":"journal-article","created":{"date-parts":[[2014,8,21]],"date-time":"2014-08-21T06:52:48Z","timestamp":1408603968000},"page":"F1004-F1011","source":"Crossref","is-referenced-by-count":4,"title":["Restoring multidrug resistance-associated protein 3 attenuates cell proliferation in the polycystic kidney"],"prefix":"10.1152","volume":"308","author":[{"given":"EunSun","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Biological Science, Sookmyung Women's University, Seoul, Republic of Korea;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun Young","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Biological Science, Sookmyung Women's University, Seoul, Republic of Korea;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu mi","family":"Woo","sequence":"additional","affiliation":[{"name":"Department of Biological Science, Sookmyung Women's University, Seoul, Republic of Korea;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duk-Hee","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Nephrology in Ewha Woman's University, Seoul, Republic of Korea;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-Hwan","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Eulji General Hospital, Seoul, Republic of Korea;
