GenomicsAcetylated histone H3K56 interacts with Oct4 to promote mouse embryonic stem cell pluripotency
The presence of acetylated histone H3K56 in human embryonic stem cells (ESCs) correlates positively with the binding of Nanog, Sox2 and Oct4 (NSO) transcription factors at their target gene promoters. However, the function of H3K56ac there has been unclear. We now report that Oct4 interacts with K56...

TranscriptomicsLigand-Dependent Enhancer Activation Regulated by Topoisomerase-I Activity
The discovery that enhancers are regulated transcription units, encoding eRNAs, has raised new questions about the mechanisms of their activation. Here, we report an unexpected molecular mechanism that underlies ligand-dependent enhancer activation, based on DNA nicking to relieve torsional stress f...

GenomicsEnhancer-bound LDB1 Regulates a Corticotrope Promoter Pausing Repression Program [ChIP-seq]
Substantial evidence supports the hypothesis that enhancers are critical regulators of cell type determination, orchestrating both positive and negative transcriptional programs; however, the basic mechanisms by which enhancers orchestrate interactions with cognate promoters during activation and re...
