Many factors, impaired by polycystin complex loss of function, may promote these biological processes, including cAMP, mTOR, and EGFR signaling pathways. In addition, microRNAs (miRs) may also regulate the ADPKD related signaling network and their dysregulation contributes to disease progression. However, the role of miRs in ADPKD pathogenesis has not been fully understood, but also the function of p53 is quite obscure, especially its regulatory contribution on cell proliferation and apoptosis. Here, we describe for the first time that miR501\u20105p, upregulated in ADPKD cells and tissues, induces the activation of mTOR kinase by PTEN and TSC1 gene repression. The increased activity of mTOR kinase enhances the expression of E3 ubiquitin ligase MDM2 that in turn promotes p53 ubiquitination, leading to its degradation by proteasome machinery in a network involving p70S6K. Moreover, the overexpression of miR501\u20105p stimulates cell proliferation in kidney cells by the inhibition of p53 function in a mechanism driven by mTOR signaling. In fact, the downregulation of this miR as well as the pharmacological treatment with proteasome and mTOR inhibitors in ADPKD cells reduces cell growth by the activation of apoptosis. Consequently, the stimulation of cell death in ADPKD cells may occur through the inhibition of mTOR\/MDM2 signaling and the restoring of p53 function. The data presented here confirm that the impaired mTOR signaling plays an important role in ADPKD.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jcp.26473","type":"journal-article","created":{"date-parts":[[2018,1,11]],"date-time":"2018-01-11T10:21:10Z","timestamp":1515666070000},"page":"6911-6924","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["MicroRNA501\u20105p induces p53 proteasome degradation through the activation of the mTOR\/MDM2 pathway in ADPKD cells"],"prefix":"10.1002","volume":"233","author":[{"given":"Lucia","family":"de Stephanis","sequence":"first","affiliation":[{"name":"Department of Biomedical and Surgical Specialty Sciences University of Ferrara Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Mangolini","sequence":"additional","affiliation":[{"name":"Unit of Urology St. Anna Hospital Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miriam","family":"Servello","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Surgical Specialty Sciences University of Ferrara Ferrara Italy"},{"name":"Unit of Urology St. Anna Hospital Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter C.","family":"Harris","sequence":"additional","affiliation":[{"name":"Division of Nephrology and Hypertension Mayo Clinic College of Medicine Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucio","family":"Dell'Atti","sequence":"additional","affiliation":[{"name":"Unit of Urology St. Anna Hospital Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Pinton","sequence":"additional","affiliation":[{"name":"Department of Morphology Surgery and Experimental Medicine University of Ferrara Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0007-0805","authenticated-orcid":false,"given":"Gianluca","family":"Aguiari","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Surgical Specialty Sciences University of Ferrara Ferrara Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,3,25]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.15586\/jkcvhl.2015.40"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1096\/fj.03-0687fje"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2184.2008.00529.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbadis.2009.03.001"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00109-012-0902-3"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(02)00716-X"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/1755-8417-2-6"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbrc.2013.10.076"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1248\/bpb.31.1496"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2010070728"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI80467"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-07-1585"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep09956"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10157-016-1289-1"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0083510"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrneph.2011.109"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.00606.2007"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms14395"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddg068"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1159\/000108643"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.freeradbiomed.2016.12.007"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5201136"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2015060634"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.krcp.2014.05.002"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncb1326"},{"key":"e_1_2_7_27_1","first-page":"745","article-title":"Synergistic roles of p53 and HIF1\u03b1 in human renal cell carcinoma\u2010cell apoptosis responding to the inhibition of mTOR and MDM2 signaling pathways","volume":"10","author":"Liu Q.
