Figure 4. Promoter methylation status of CBXs in BLCA (UALCAN). The promoter of AKAP8L was hypomethylated in (A) BLCA and (B) CHOL tissues. The promoter of AKAP8L was hypermethylated in (C) KIRP tissues. The promoter of AKAP8L was hypomethylated in (D) KIRC, (E) LIHC and (F) LUSC tissues. * p < 0.05, *** p < 0.001.
