[Epigenetic dysregulation and emerging treatment strategies in myelodysplastic syndromes].

The epigenome regulates transcription of target genes through DNA methylation- or histone methylation/acetylation/phosphorylation/ubiquitination-mediated alteration of genomic function or chromatin conformation. Recent genomic studies have shown that multiple genes encoding epigenetic regulators are frequently and recurrently mutated in MDS, suggesting that epigenetic dysregulation is significantly associated with the molecular pathogenesis and clinical features of MDS. In this review, we will present our recent findings together with others, focusing on physiological molecular functions of epigenetic regulators recurrently mutated in MDS and on functional correlation between dysregulated epigenomic regulators and molecular pathogenesis/clinical features of MDS.
