To confirm the above findings in larger samples, we used HNSCC TCGA datasets (Tumor N = 520, Normal N = 44), derived from TSVdb16, TANRIC17 and OMCD18 to obtain the expression levels of EGFR A and D isoforms, EGFR-AS1 and miR-891b respectively. Here, EGFR is linked to head and neck squamous cell carcinoma.
