This upregulated NAT10 stability mediates the enhancement of specific tRNA ac4C modifications, subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling, IL-8 signaling, and PTEN signaling that play roles in regulating HNSCC malignant progression, ultimately influencing the survival and prognosis of HNSCC patients. This evidence concerns the gene IL6 and head and neck squamous cell carcinoma.
