We found that the expression levels of TFAP2C, RAP2A, NCOR2, MDGA2, GTF2H1, and DOCK11 were down-regulated in one of the two ESCC cell lines, while the expression of DAZAP1 was inhibited by the ectopic miR-10b in both KYSE450 and KYSE510 cell lines (Figure 2B). This evidence concerns the gene RAP2A and esophageal squamous cell carcinoma.
