The UALCAN database showed that promoter methylation levels of EPOR were higher in COAD, ESCA, KIRC, KIRP, LIHC, LUAD, LUSC, and PAAD cancer tissues than in normal tissues, and lower in BLCA, BRCA, uterine corpus endometrial carcinoma (UCEC), and THCA cancer tissues than in normal tissues (Figure 9C). Here, EPOR is linked to pancreatic adenocarcinoma.
