Abstract

Both epigenetic and genetic alternations are involved in cancer formation. In this study, we have identified the methylation frequency of p16 and endothelin receptor type B (EDNRB) of 26 leukemia patients and 8 randomly selected normal blood donors in Taiwan. Promoter methylation of p16 was detected in 85% of acute lymphocytic leukemia (ALL), 83% in acute myeloid leukemia (AML) whereas no methylation was detected in chronic myeloid leukemia (CML) in blast crisis. Hypermethylation of EDNRB was observed in 92% of ALL, 75% AML and 100% in CML in blast crisis. No aberrant methylation of p16 and EDNRB was found in 8 normal blood donors. Taken together, aberrant methylation of p16 and EDNRB was highly prevalent in leukemia patients in Taiwan.
