MetabolomicsPathogenic NLRP3 mutants form constitutively active inflammasomes resulting in immune-metabolic limitation of IL-1β production

BACKGROUND: Cryopyrin-Associated Periodic Syndrome (CAPS) is an autoinflammatory condition consequence of monoallelic variants in the NLRP3 gene that exacerbate IL-1β production. These variants are gain-of-function, but the exact regulatory mechanism of the NLRP3 CAPS-inflammasom...

GenomicsThe long noncoding RNAs NEAT1 and MALAT1 bind active chromatin sites
Long noncoding RNAs (lncRNAs) are important regulators of chromatin; however, the mechanistic roles for many lncRNAs are poorly understood in part because their direct interactions with genomic loci and proteins are difficult to assess. We used CHART-seq to map the genomic binding sites for two high...

GenomicsCharacterization of genome-wide enhancer-promoter interactions reveals co-expression of interacting genes and modes of higher order chromatin organization
Recent epigenomic studies have predicted thousands of potential enhancers in the human genome. However, there has not been systematic characterization of target promoters for these potential enhancers. Using H3K4me2 as a mark for active enhancers, we identified genome-wide enhancer-promoter interact...

GenomicsEpigenetic Repogramming by an Environmental Carcinogen Through Chromatin Domain Disruption
Histone modifications associated with gene silencing typically mark large contiguous regions of the genome forming repressive chromatin domain structures. Since the repressive domains exist in close proximity to active regions, maintenance of domain structure is critically important. This study show...

TranscriptomicsExtensive promoter-centered chromatin interactions provide a topological basis for transcription regulation
Higher-order chromosomal organization for transcription regulation is poorly understood in eukaryotes. Using genome-wide Chromatin Interaction Analysis with Paired-End-Tag sequencing (ChIA-PET), we mapped long-range chromatin interactions associated with RNA polymerase II in human cells and uncovere...

TranscriptomicsGenome-wide localization of exosome components to active promoters and chromatin insulators in Drosophila
Chromatin insulators are functionally conserved DNA-protein complexes that are situated throughout the genome and organize independent transcriptional domains.  Previous work implicated RNA as an important cofactor in chromatin insulator activity, although the mechanisms by which RNA affects insulat...

TranscriptomicsGenome-wide profiling of salt fractions maps physical properties of chromatin
We applied genome-wide profiling to successive salt-extracted fractions of micrococcal nuclease-treated Drosophila chromatin. Chromatin fractions extracted with 80mM or 150mM NaCl after digestion contain predominantly mononucleosomes and represent calssical 'active' chromatin. Profiles of these low-...

GenomicsCTCF demarcates chromatin domains
Insulators are DNA elements, which prevent inappropriate interactions between the neighboring regions of the genome. They can be functionally classified as either enhancer blockers or domain barriers. CTCF (CCCTC binding factor) is the only known major insulator binding protein in the vertebrates a...

GenomicsTE-associated chromatin variation in mice livers
Chromatin accessibility is a hallmark of active regulatory function in the genome and variation of chromatin accessibility across individuals has been shown to contribute to complex traits and disease susceptibility. However, the mechanisms responsible for chromatin variation among different individ...

GenomicsH2A.Z Facilitates Access of Active and Repressive Complexes to Chromatin in Embryonic Stem Cell Self-renewal and Differentiation
Chromatin modifications have been implicated in the self-renewal and differentiation of embryonic stem cells (ESCs). However, the function of histone variant H2A.Z in ESCs remains unclear. We show that H2A.Z is highly enriched at promoters and enhancers and is required for both efficient self-renewa...
