Further research reported that after treating seven different esophageal cancer cell lines (KYSE-30, 170, 200, 510, 790, 960, and 1170) with 5-AzaCd, it was found that in one cell line (KYSE-170), the expression level of MYEOV was high, but there was no accompanying DNA amplification. Here, MYEOV is linked to esophageal cancer.
