Moreover, differential expression analysis suggested that the levels of LINC01116, LMO7‐AS1, KDM4A‐AS1, KMT2E‐AS1, KTN1‐AS1, LINC00839, DLX6‐AS1, UBL7‐AS1, and DDX11‐AS1 were notably up‐regulated in 77 ESCC samples (Table S1) or 162 EC tumor tissues (Fig. 2B) than in 11 normal tissues. This evidence concerns the gene DLX6 and esophageal squamous cell carcinoma.
