The results demonstrated that the IL18RAP expression levels and DNA methylation were negatively correlated in 15 cancers, including UVM, THCA, TGCT, BRCA, PRAD, KICH, cholangiocarcinoma (CHOL), KIRP, PAAD, THYM, LGG, GBM, LUAD, LAML, and DLBC (Figure 3E). The gene discussed is IL18RAP; the disease is cholangiocarcinoma.
