(Submitter supplied) Cellular differentiation is orchestrated by lineage-specific transcription factors and associates with cell type-specific epigenetic signatures. Here, we utilized stage-specific, epigenetic "fingerprints" to deduce key transcriptional regulators of a cellular differentiation process. In the model of human macrophage differentiation, we globally mapped the distribution of epigenetic enhancer marks (histone H3 lysine 4 monomethylation, histone H3 lysine 27 acetylation, and the histone variant H2AZ) and show that cell type-specific epigenetic "fingerprints" correlate with specific, de novo derived motif signatures at all differentiation stages studied (hematopoietic progenitor cell, monocyte, macrophage). more...

(Submitter supplied) Myeloid cells of the granulocytic-monocytic (GM) lineage develop in a process orchestrated mainly by the transcription factors PU.1 and CEBPA, but how these factors collaborate on a global scale during GM-lineage differentiation remains uncharacterized. To address this question we have combined epigenetic profiling, transcription factor binding and gene expression analyses of successive stages of murine GM-lineage differentiation and show that PU.1 and CEBPA binds to GM enhancers with distinct kinetics. more...

(Submitter supplied) The nuclear receptor Peroxisome Proliferator Activator Receptor (PPAR ) is the target of antidiabetic thiazolidinedione drugs, which improve insulin resistance but have side-effects that limit widespread use. PPAR is required for adipocyte differentiation, but is also expressed in other cell types, notably macrophages, where it influences atherosclerosis, insulin resistance, and inflammation. A central question is whether PPAR binding in macrophages occurs at the same or different genomic locations compared to adipocytes. more...

(Submitter supplied) Conversion of monocytes to osteoclasts is a unique terminal differentiation process within the hematopoietic system involving differentiation and massive cell fusion. Here we focused on DNA methylation changes during osteoclastogenesis. Hypermethylation and hypomethylation changes took place in several thousand genes, including all relevant functional categories in osteoclast differentiation and function.

(Submitter supplied) We conducted chromatin immunoprecipitation followed by sequencing (ChIP-seq) and proximity ligation-assisted ChIP-seq (PLAC-seq) for enhancers and promoters (E-P) using left ventricular tissues from dilated cardiomyopathy (DCM) patients and non-heart failure (NF) donors. Differential active enhancer H3K27ac and promoter H3K4me3 regions were identified between NF and DCM. While the average read density (ARD) for H3K27ac is similar between NF and DCM, the ARD of H3K4me3 is significantly lower in DCM samples than in NF.Super-enhancer (SE) analysis revealed that 929 and 129 genes linked to NF- and DCM-specific SE, respectively, and three unique SE-associated genes between NF and DCM were identified.Moreover, the differential E-P interactions were observed in the known heart failure gene loci and are correlated with the gene expression levels. more...

(Submitter supplied) Recent studies suggest a hierarchical model in which lineage-determining factors act in a collaborative manner to select and prime cell-specific enhancers, thereby enabling signal-dependent transcription factors to bind and function in a cell type-specific manner. Consistent with this model, TLR4 signaling primarily regulates macrophage gene expression through a pre-existing enhancer landscape. However, TLR4 signaling also induces priming of ~3000 enhancer-like regions de novo, enabling visualization of intermediates in enhancer selection and activation. more...

(Submitter supplied) Unraveling the complexity of transcriptional programs coded by different cell types has been one of the central goals of cell biology. Using genome-wide location analysis, we examined how two different cell types generate different responses to the NF-kappaB signaling pathway. We showed that, after tumor necrosis factor-alpha (TNF-alpha) treatment, NF-kappaB p65 subunit binds to distinct genome locations and subsequently induces different subsets of genes in human monocytic THP-1 cells versus HeLa cells . more...

(Submitter supplied) While cell-type-restricted enhancers are initially detected following cooperative binding of positionally-determined DNA binding transcription factors during determination/differentiation, it remains unknown whether there are preceding events in embryonic stem cells (ESCs) that are functionally important to activate cell-type-restricted enhancer networks. Here, using murine macrophages as a model, we report that, while largely devoid of characteristic enhancer marks (H3K4me1, H3K4me2, H3K27Ac, H3K27me3 and p300) in ESCs, macrophage enhancers are activated as transcription units mainly by the binding of a single, at most two, ESC transcription factors. more...
