TranscriptomicsLudwig Institute/UCSD ENCODE project June 2007 Release
The readout of genome information is controlled by transcriptional regulatory elements, but a comprehensive view of the combinatorial control by these DNA sequences, which bind regulatory protein and/or the modified histones in regulating gene transcription, is clearly preliminary. We have developed...

GenomicsNatural genetic variation perturbs collaborative transcription factor binding required for enhancer selection and function
Natural genetic variation between two mouse strains was used as a natural mutagenesis screen to test various aspects of the proposed model for enhancer selection and function. Chromatin marks H3K4me2, H3K27Ac, and transcription factors PU.1, C/EBPa, and p65 were assessed by ChIP-Seq and GRO-Seq and ...

TranscriptomicsEnvironment Drives Selection and Function of Enhancers Controlling Tissue-Specific Macrophage Identities
Macrophages reside in essentially all tissues of the body and play key roles in innate and adaptive immune responses. Distinct populations of tissue macrophages also acquire context-specific functions that are important for normal tissue homeostasis. To investigate mechanisms responsible for tissue-...

GenomicsMutant Huntingtin promotes neuronal death through cell autonomous microglial activation via myeloid lineage- determining factors
Huntington's Disease (HD) is a fatal neurodegenerative disorder caused by an extended polyglutamine repeat in the N-terminus of the huntingtin (Htt) protein. Reactive microglia and elevated cytokine levels are observed in the brains of HD patients, but the extent to which neuroinflammation results f...

TranscriptomicsGlobal changes in the nuclear positioning of chromatin domains and genomic interactions that orchestrate B cell fate
The genome is folded into domains that are located in either transcriptionally inert or permissive compartments. Here we used genome-wide strategies to characterize domains during B cell development. Structured Interaction Matrix Analysis revealed that CTCF occupancy was primarily associated with i...

TranscriptomicsSimple combinations of lineage-determining transcription factors prime cis-regulatory elements required for macrophage and B cell identities
Genome-scale studies have revealed extensive co-localization of transcription factors in a given cell type as well as substantial differences in the binding patterns of specific transcription factors between cell types. Several mechanisms have been proposed to explain these observations, including t...

TranscriptomicsA protective strategy against hyperinflammatory responses requiring the non-transcriptional actions of GPS2
The association between hyper-inflammatory states and numerous diseases is widely recognized, but our understanding of the molecular strategies that have evolved to prevent uncontrolled activation of inflammatory responses remains incomplete. Here, we report a critical, non-transcriptional role of G...

TranscriptomicsA global network of transcription factors, involving E2A, EBF1 and FOXO1, that orchestrates the B cell fate
It is now established that the transcription factors E2A, EBF1 and FoxoM-BM- 1 play critical roles in B cell development. Here we show that E2A and EBF1 bound regulatory elements present in the Foxo1 locus. E2A and EBF1 as well as E2A and Foxo1, in turn, were wired together by a vast spectrum of cis...

TranscriptomicsRev-Erbs repress macrophage gene expression by inhibiting enhancer-directed transcription
Rev-Erba and Rev-Erbb are nuclear receptors that regulate the expression of genes involved in the control of circadian rhythm, metabolism, and inflammatory responses. Rev-Erbs function as transcriptional repressors by recruiting NCoR/HDAC3 co-repressor complexes to Rev-Erb response elements in enha...
