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 ...

GenomicsControl of VEGF-A trancriptional programs by pausing and genomic compartmentalization
Vascular endothelial growth factor A (VEGF-A) is a master regulator of vascular development and function. Consequently, VEGF-A regulated gene expression programs have been under heavy research. In this study we study the transcriptional regulation of VEGF-A-responsive genes in primary aortic endothe...

GenomicsRemodeling of the enhancer landscape during macrophage activation is coupled to enhancer transcription
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 si...
