TranscriptomicsTwo functionally distinct subsets of mast cells generated through IL-2 independent CD25 activities
CD25 (IL-2R) can be expressed on the surface of immune cells in the absence of other chains of the interleukin-2 receptor (IL-2R), which are indispensable for IL-2 signaling. We identified two novel mast cell subsets, characterized by the differential expression of surface CD25, and by the ability t...

GenomicsCo-regulation of transcription factor binding and nucleosome occupancy through DNA features of mammalian enhancers
In mammalian cells transcription factors (TFs) preferentially bind sites contained in regions of high nucleosomal occupancy, as determined by nucleotide-dependent computational analysis. This observation suggests that nucleosomes may act as gatekeepers of TF binding sites. We hypothesized that in ma...

GenomicsThe Histone Methyltransferase Wbp7 Controls Macrophage Function through GPI Glycolipid Anchor Synthesis. [ChIP_seq]
Histone methyltransferases catalyze site-specific deposition of methyl groups, enabling recruitment of transcriptional regulators. In mammals, trimethylation of lysine 4 in histone H3, a modification localized at the transcription start sites of active genes, is catalyzed by six enzymes (SET1a and S...

TranscriptomicsA large fraction of extragenic RNA Pol II transcription sites overlap enhancers
Mammalian genomes are pervasively transcribed outside mapped protein-coding genes. One class of extragenic transcription products is represented by long non-coding RNAs (lncRNAs), some of which result from Pol_II transcription of bona-fide RNA genes. Whether all lncRNAs described insofar are product...

GenomicsHDAC-regulated myomiRs control BAF60 variant exchange and direct the functional phenotype of fibroadipogenic progenitors in dystrophic muscles
Fibro-adipogenic progenitors (FAPs) are emerging cellular components of the skeletal muscle regenerative environment. The alternative functional phenotype of FAPs - either supportive of muscle regeneration or promoting fibro-adipogenic degeneration M-bM-^@M-^S is a key determinant in the pathogenesi...

GenomicsIdentification and Characterization of Enhancers Controlling the Inflammatory Gene Expression Program in Macrophages
Enhancers determine tissue-specific gene expression programs. Enhancers are marked by high histone H3 lysine 4 mono-methylation (H3K4me1) and by the acetyl-transferase p300, which has allowed genome-wide enhancer identification. However, the regulatory principles by which subsets of enhancers become...

GenomicsPAT-ChIP-Seq: a novel tool for the epigenetic profiling of formaldehyde-fixed and paraffin-embedded (FFPE) pathology samples
Epigenetic alterations in the pattern of DNA and histone modifications play a crucial role in cancer development. Analysis of patient samples, however, is hampered by technical limitations in the study of chromatin structure from pathology archives that typically consist of heavily fixed, paraffin-e...

GenomicsLatent enhancers unveiled by stimulation expand and adapt the available cis-regulatory repertoire (FAIRE-seq)
According to current models, transcription factors (TFs) activated by extracellular stimuli operate in the context of a pre-established enhancer repertoire induced and maintained by lineage-specific TFs. Here, we uncovered the existence of latent enhancers, defined as regions of the genome that in t...
