Integrated analysis of the prognostic values of RNA-binding proteins in head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma is a malignant tumor of the upper aerodigestive tract. These RNA-binding proteins (RBPs) influence post-transcriptional in cells and regulate cell physiology, participate in regulating RNA stability, alternative splicing, translation, modification, localization, and apoptosis. We used RNA sequencing data from The Cancer Genome Atlas to display dysfunctional RBPs microenvironments and provide potential useful biomarkers for head and neck squamous cell carcinoma (HNSCC) diagnosis and prognosis. Six RBPs (DNMT1, PCF11, EIF5A2, RNASE10, PSMA6, and IGF2BP2) were selected as independent prognosis factors of HNSCC patients. The Kyoto Encyclopedia of Genes and Genomes were mainly enriched in RNA transport, Spliceosome, RNA degradation, mRNA surveillance pathway, and Epstein-Barr virus infection. cBioPortal results demonstrated that these six genes were altered in 150 samples out of 504 HNSCC patients (30%) and the amplification of IGF2BP2 was the largest frequent copy-number alteration. Based on the online database, we identified novel RBPs markers for the prognosis of HNSCC.
