Moreover, gender, age groups, and tumor locations did not significantly correlate with the expression levels of these genes (<i>p</i>> 0.05). Nevertheless, significant differences occurred between histopathological grades and the gene expression levels of <i>JAK2</i> (<i>p</i>< 0.001), <i>STAT3</i> (<i>p</i>= 0.001), and <i>CTLA4</i> (<i>p</i>< 0.001).</p><p><strong>Conclusion: </strong>The overexpression of <i>JAK2</i>, <i>STAT3</i>, and <i>CTLA4</i> can be considered triggers for OSCC development. It may be beneficial to conduct future research on OSCC by considering downstream genes involved in the <i>JAK2</i>/<i>STAT3</i>/<i>CTLA4</i> axis.</p>","PeriodicalId":73702,"journal":{"name":"Journal of dentistry (Shiraz, Iran)","volume":"26 1","pages":"25-32"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11909409/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
