(Submitter supplied) Many researchers have reported the prognostic significance of various DNA methylation changes in patients with acute myeloid leukemia (AML). We aimed for a comprehensive evaluation of these epigenetic aberrations that would refine the AML prognostication. We designed a sequencing panel targeting 239 regions described in literature as having a prognostic impact or being commonly associated with AML pathogenesis and analyzed 178 diagnostic samples of AML patients divided into test (n=128) and validation cohort (n=50).

(Submitter supplied) Cytogenetically normal acute myeloid leukemia (CN-AML) comprise between forty and fifty percent of all adult acute myeloid leukemia (AML) cases. In this clinically diverse group molecular aberrations such as FLT3ITD, NPM1 and CEBPA mutations recently have added to the prognostic accuracy. Aberrant DNA methylation is a hallmark of cancer including AML. We investigated in total 89 CN-AML samples in a test and a validation cohort for genome-wide promoter DNA methylation with Illumina Methylation Bead arrays and compared them to normal myeloid precursors and global gene expression. more...

(Submitter supplied) Aberrant changes in 5-hydroxymethylcytosine (5hmC) are a unique epigenetic feature in many cancers including acute myeloid leukemia (AML). However, genome-wide analysis of 5hmC in plasma cell-free DNA (cfDNA) remains unexploited in AML patients. We used a highly sensitive and robust nano-5hmC-Seal technology and profiled genome-wide 5hmC distribution in 239 plasma cfDNA samples from 103 AML patients and 81 non-cancer controls. more...

(Submitter supplied) Acute myeloid leukemia (AML) causes the most leukemia-related deaths in the United States. Although genetic changes are assessed in the clinic for risk stratification, current classifications are imperfect and epigenetic determinants of AML curability remain poorly understood. To address this gap in knowledge we performed genome-wide DNA methylation analysis using the next-generation sequencing-based Digital Restriction Enzyme Analysis of Methylation (DREAM) assay on 96 clinical AML samples, and 35 normal peripheral blood controls. more...

(Submitter supplied) Epigenetic therapy, using hypomethylating agents (HMA), is known to be effective in the treatment of high-risk myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients who are not suitable for intensive chemotherapy or allogeneic stem cell transplantation. However, response rates to HMA are low and there is an unmet need in finding prognostic and predictive biomarkers of treatment response. more...
