The technology allows for the creation of multicellular microenvironments, the incorporation of diverse extracellular matrix substrates, and the deployment of additional components like growth factors, nanoparticles, and genetic modulators. This versatility facilitates the study of complex tumor behaviors, such as perineural invasion, and enables high-throughput drug screening for personalized therapies.

The top 10 drugs were validated through molecular docking.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>A total of 47 DEGs were identified, primarily involved in mitotic sister chromatid separation according to GO enrichment analysis. CIBERSORT analysis revealed significant changes in B cell naive and dendriform cells (DCs) resting content in the OM group. PRKAA2, encoding the AMP-activated protein kinase (AMPK) catalytic subunit, showed a negative correlation with DC resting content. Molecular docking from CMAP identified aloisine and teniposide as potential agents for OM induced by radiotherapy and chemotherapy.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>AMPK emerges as a crucial regulator in OM post radiotherapy and chemotherapy, implicating sister chromatid separation, where DCs may play a pivotal role. Aloisine and Teniposide appear promising for OM prevention or treatment associated with these treatments.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16588,"journal":{"name":"Journal of Oral Pathology & Medicine","volume":"54 5","pages":"325-333"},"PeriodicalIF":2.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
