EZH2 and cholangiocarcinoma: The results suggested that compared with corresponding normal tissues, the methylation state of EZH2 was lower in BLCA, UCEC, LUAD, LUSC, prostate adenocarcinoma (PRAD), READ, testicular germ cell tumors (TGCT), and thyroid carcinoma (THCA), and higher in cholangiocarcinoma (CHOL) (Figure 7A).
