The cut-off of miR-188-5p was 6.74. miRDB and mirNET predicted BUB3 and SUMO2 as a potential target gene of miR-188-5p. Additionally, increased expression of BUB3 and SUMO2 was observed in the K-562 cell. Bub3 is implicated in apoptosis and the cell cycle, whereas Sumo2 protein sumoylation and DNA binding are believed to contribute to catabolic processes.</p><p><strong>Conclusions: </strong>Our results suggest that miR-188-5p acts as an oncomiRNA in CML pathogenesis and may be a promising therapeutic target for CML.</p>","PeriodicalId":18755,"journal":{"name":"Molecular Biology Reports","volume":"52 1","pages":"269"},"PeriodicalIF":2.6,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143523780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
