Genome-wide maps of chromatin state in pluripotent and lineage-committed cells
We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four billion bases of sequence… Expand
Genomewide Analysis of PRC1 and PRC2 Occupancy Identifies Two Classes of Bivalent Domains
In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the… Expand
ASXL1 mutations promote myeloid transformation through loss of PRC2-mediated gene repression.
Recurrent somatic ASXL1 mutations occur in patients with myelodysplastic syndrome, myeloproliferative neoplasms, and acute myeloid leukemia, and are associated with adverse outcome. Despite the… Expand
GC-Rich Sequence Elements Recruit PRC2 in Mammalian ES Cells
Polycomb proteins are epigenetic regulators that localize to developmental loci in the early embryo where they mediate lineage-specific gene repression. In Drosophila, these repressors are recruited… Expand
Reprogramming factor expression initiates widespread targeted chromatin remodeling.
Despite rapid progress in characterizing transcription factor-driven reprogramming of somatic cells to an induced pluripotent stem cell (iPSC) state, many mechanistic questions still remain. To gain… Expand
Loss of BAP1 function leads to EZH2-dependent transformation
The tumor suppressors BAP1 and ASXL1 interact to form a polycomb deubiquitinase complex that removes monoubiquitin from histone H2A lysine 119 (H2AK119Ub). However, BAP1 and ASXL1 are mutated in… Expand
H2A.Z landscapes and dual modifications in pluripotent and multipotent stem cells underlie complex genome regulatory functions
BackgroundThe histone variant H2A.Z has been implicated in nucleosome exchange, transcriptional activation and Polycomb repression. However, the relationships among these seemingly disparate… Expand
The MicrobesOnline Web site for comparative genomics.
At present, hundreds of microbial genomes have been sequenced, and hundreds more are currently in the pipeline. The Virtual Institute for Microbial Stress and Survival has developed a publicly… Expand

Loss of Asxl1 results in myelodysplastic syndrome, whereas concomitant deletion of Tet2 restores HSC self-renewal and triggers a more severe disease phenotype distinct from that seen in single-gene… Expand
AF10 regulates progressive H3K79 methylation and HOX gene expression in diverse AML subtypes.
Homeotic (HOX) genes are dysregulated in multiple malignancies, including several AML subtypes. We demonstrate that H3K79 dimethylation (H3K79me2) is converted to monomethylation (H3K79me1) at HOX… Expand
