Over-expression of LINC00936 contributed to decreasing miR- 221-3p expression and increasing LAMA3 expression. LINC00936 overexpression or miR-221- 3p silencing downregulated the levels of PCNA, MMP-2, MMP-9, and VEGF and decreased cell proliferation, migration, invasion, angiogenesis, and ovarian cancer tumorigenesis.</p><p><strong>Conclusion: </strong>Collectively, overexpression of LINC00936 suppressed the development of ovarian cancer by competitively binding to miR-221-3p and controlling LAMA3 expression. These results could serve as a novel theoretical base for the treatment of ovarian cancer.</p>","PeriodicalId":20774,"journal":{"name":"Recent patents on anti-cancer drug discovery","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10332426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
