Aberrant DNA methylation profiling of classic Philadelphia Negative Myeloproliferative Neoplasms

ABSTRACT: Since most DNA methylation studies in Classic Philadelphia-negative myeloproliferative neoplasms (MPNs) M-bM-^@M-^S polycythaemia vera (PV), essential thrombocythaemia (ET), and primary myelofibrosis (PMF) - have been performed on a gene-by-gene basis, a more comprehensive methylation profiling is needed to know the real implication of this alteration. In order to investigate the DNA methylation profile in chronic and transformed phase MPNs, we performed genome-wide DNA methylation arrays in 71 chronic (24 PV, 23 ET and 24 PMF) and 13 transformed MPNs. The three types of chronic MPNs showed the same aberrant DNA methylation pattern when compared to controls. Differentially methylated genes (DMG) were enriched in a gene network centered on the NF-M-NM-:B pathway, indicating that they may be
