Fig 1: DFNA5 expression in human head and neck squamous cell carcinoma. (A-B) The expression level of DFNA5 in HNSCCs and healthy tissues as calculated from the gene expression data of the Oncomine database (A), and TIMER database (B). (C-F) Analysis of DFNA5 expression in different subtypes of HNSCC using gene expression data from the Oncomine database. (G) In vitro validation of the expression level of DFNA5 in the HNSCC cell lines SCC-15 (ATCC CRL-1623), Cellosaurus HN6 (CVCL_8129), and human oral squamous cell carcinoma (HSC-3); human normal oral keratinocytes (NOKs) were used as control cells. *P < 0.05, **P < 0.01, ***P < 0.001
