This study focuses on miR-876, a microRNA significantly associated with OSCC recurrence and clinical outcomes. Analysis of miRNA expression profiles from recurrent OSCC patients revealed that miR-876-5p is markedly upregulated in recurrent tumor tissues and the high expression of miR-876-5p correlates with reduced disease-free and overall survival. Functional assays demonstrated that miR-876 enhances OSCC cell growth, migration, and stemness, contributing to chemoresistance. Mechanistically, miR-876-5p directly targets SOCS4, leading to increased STAT3 activation and subsequent upregulation of PD-L1, which facilitates immune evasion. Additionally, exposure to the tobacco-specific carcinogen NNK was found to induce miR-876 expression and STAT3 activation, implicating environmental factors in miR-876 regulation and promote cancer recurrent. These findings identify the miR-876-5p-SOCS4-STAT3 axis as a critical pathway in OSCC progression, highlighting miR-876-5p as a potential biomarker and therapeutic target to improve treatment outcomes in OSCC patients.</p>","PeriodicalId":9385,"journal":{"name":"Cancer Cell International","volume":"25 1","pages":"114"},"PeriodicalIF":5.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11938556/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143718094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
