KRT17 expression level is confirmed to be elevate in most OSCC cell lines (BHY, BICR 1, BICR 7, HN, as evidenced in RNAseq (ArrayExpress ID: “E-MTAB-2706”) and array public experiments (E-GEOD-30784, log2FC=4.1 for “oral squamous cell carcinoma vs normal samples”, p-value=2.19E−38). This evidence concerns the gene KRT17 and oral cavity squamous cell carcinoma.
