METTL3 and esophageal squamous cell carcinoma: To further identify METTL3‐regulated lncRNAs, a Venn diagram was employed to intersect the molecules confirmed to be METTL3‐mediated m6A‐modified in the RM2Target database with differentially expressed lncRNAs in the TCGA‐ESCC and GSE53625 datasets (Table S6).
