However, the detailed mechanisms have not been fully investigated. The expression of ZNF139 in both GC tissues and cell lines was tested, then SGC7901\/ADR or SGC7901 cells were transfected with ZNF139-siRNA, miR-185 analog, or pcDNA-ZNF139. Cell activity was determined by MTT assay. Real-time PCR and Western blot were utilized to detect ZNF139, miR-185, and multidrug resistance (MDR) related genes including MDR1\/P-gp, GST-\u03c0, MRP-1, Bcl-2, TS and Bax. ChIP and dual luciferase activity assay were used to investigate regulation between ZNF139 and miR-185. Increased ZNF139 and decreased miR-185 expression were detected in GC tissues and cell lines. Transfection with ZNF139-siRNA into SGC7901\/ADR cells markedly increased expression of miR-185, and treating with chemotherapeutic drugs ADR, 5-FU, L-OHP, the survival rate of SGC7901\/ADR cells obviously decreased after ZNF139-siRNA transfection. On the other hand, transfection with pcDNA-ZNF139 in GC cell line SGC7901 resulted in an increased expression level of ZNF139 and a decline in the expression level of miR-185, meanwhile drug resistance of GC cells was clearly enhanced to ADR, 5-FU, L-OHP. Dual luciferase activity assay demonstrated that ZNF139 inhibited transcriptional activities of miR-185\u2019s promoter in cells transfected with the reporter plasmid encompassing the upstream promoter region of miR-185 along with pcDNA-ZNF139. Our data reveal that ZNF139 might promote MDR gene MDR1\/P-gp, MRP-1 and Bcl-2 by prohibiting miR-185.<\/jats:p>","DOI":"10.1042\/bsr20181023","type":"journal-article","created":{"date-parts":[[2018,8,20]],"date-time":"2018-08-20T19:55:17Z","timestamp":1534794917000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["ZNF139 increases multidrug resistance in gastric cancer cells by inhibiting <i>miR-185<\/i>"],"prefix":"10.1042","volume":"38","author":[{"given":"Bibo","family":"Tan","sequence":"first","affiliation":[{"name":"Department of General Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province 050011, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Li","sequence":"additional","affiliation":[{"name":"Department of General Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province 050011, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qun","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of General Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province 050011, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liqiao","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of General Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province 050011, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of General Surgery, The Fourth Hospital of Hebei Medical University, Shijiazhuang City, Hebei Province 050011, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2018,9,5]]},"reference":[{"key":"2021111619124442900_B1","doi-asserted-by":"publisher","first-page":"87","DOI":"10.3322\/caac.21262","article-title":"Global cancer statistics, 2012","volume":"65","author":"Torre","year":"2015","journal-title":"CA Cancer J.
