Mutation allele burden remains unchanged in chronic myelomonocytic leukaemia responding to hypomethylating agents

Chronic myelomonocytic leukaemia is treated with agents that modify DNA methylation but whether they have direct cytotoxic effects is unclear. Here, the authors show that cells from treated patients show marked methylation changes without altered somatic mutation burden, suggesting that cytotoxicity...

Sumario:Chronic myelomonocytic leukaemia is treated with agents that modify DNA methylation but whether they have direct cytotoxic effects is unclear. Here, the authors show that cells from treated patients show marked methylation changes without altered somatic mutation burden, suggesting that cytotoxicity is not a major factor in therapeutic efficacy.
