The frequencies of TSG methylation status in adenomas according to expression of DNMT1, DNMT3A, and DNMT3B. (A) The groups with overexpression of DNMT1 and DNMT3A had more high-methylation tumors than the groups with low-expression of DNMT1 and DNMT3A (72% vs. 40% and 69% vs. 40%, respectively). (B) The DNMTs 2 group had more high-methylation tumors than DNMTs 1 and DNMTs 0 groups (76%, 35%, and 40%, respectively).
