DNA methylation level of adhesion molecules in NP and HP group. Comparison of DNA methylation level of (A–B) MUC1, (C–D) CDH1, and (E–F) CTNNB1 on endometrium from HP and NP group. 5 samples in each group were used for testing methylation level of MUC1 by bisulfite sequencing methods, and 20 samples in each group were used for testing methylation level of CDH1 and CTNNB1 by Sequenom MassARRAY. There was no significant difference in the methylation level of MUC1 between endometria from HP and NP group. CDH1 and CTNNB1 were significantly hypermethylated in endometrium from HP group than that from NP group. Profiling of DNA methylation level of CpG sites in (A) MUC1, (C) CDH1, and (E) CTNNB1 promoter region was presented as an epigram
