Project description:Gains and losses in DNA methylation are prominent genomic features of all mammalian cell types. To gain insight into mechanisms that could promote shifts in DNA 5-hydroxymethylation (5hmc) patterns and thus contribute to cell fate, including malignant transformation, we performed genome-wide mapping of 5hmc in purified wild type and Dnmt3a conditional knockout hematopoietic stem cells (HSCs) using cytosine-5-methylenesulphonate sequencing (CMS-seq). Comparing anti-CMS pulldown to input control, we identified 107,549 and 175,682 peaks of 5hmc enrichment in control and Dnmt3a knockout HSCs, respectively. Whole genome CMS-enriched bisulfite sequencing of secondarily-transplanted wild-type and Dnmt3a conditional knockout hematopoietic stem cells using Illumina HiSeq 2000
