Project description:We investigated an intergenic haplotype on chr21q22, linked to five different inflammatory diseases. We used a functional approach (massively-parallel reporter assay; MPRA) to first identify active enhancers at the locus in primary human macrophages, and then determine if candidate variants within these regulatory regions might alter enhancer activity. In doing so, we discovered a mechanism that orchestrates macrophage responses during chronic inflammation and delineated how the risk haplotype increases expression of the causal gene, ETS2.
Project description:We combined Self-Transcribing Active Regulatory Region Sequencing (STARR-seq) with an enrichment step using chromatin immunoprecipitation in a massively parallel reporter assay. We applied this assay, termed ChIP-STARR-seq, to normal (primed) and naive human embryonic stem cells, building up a comprehensive catalogue of functional enhancers. This database record describes the STARR-RNA-seq component.

Project description:The activity of enhancers with dynamic P300 binding or mutagenized nuclear receptor motifs was assessed by massively parallel reporter assay during CM maturation.
Project description:We performed a Massively Parallel Reporter Assay (MPRA) to screen >30,000 human-specific substitutions in ChIP-seq-identified Human Gain Enhancers (HGEs) and Human Accelerated Regions (HARs), highly conserved non-coding regions that show accelerated sequence evolution in humans. After comparing human and chimpanzee reference alleles, we used a second MPRA to deconvolute individual substitutions within differentially active enhancers from substitutions in the same fragment and from other variants (human segregating variants or chimpanzee-specific variants) to isolate their specific effects on enhancer activity.
