We figured out that BAX methylation showed a strong link with BAX mRNA expression in most cancer types, such as UCEC, LGG (FDR < 0.0001), UVM, HNSC, PRAD, LUAD (FDR ≤ 0.001), OV, TGCT, MESO, GBM, KICH, BLCA, BRCA, READ, PCPG, USC, CESC, COAD, PAAD, ESCA, SARC and SKCM (FDR < 0.05) (Figure 11A). The gene discussed is BAX; the disease is cancer.
