Inflammation-sensitive super enhancers form domains of coordinately regulated enhancer RNAs. The reproducibility of enhancers identified by NRSA. Rank of the previously reported three enhancers regulating KIT. NRSA not only quantifies nascent transcription for known genes, but also detects, annotates, and quantifies active enhancers, and predict their targets based on the closest TSS transcriptional start sitewithin a distance default: 50kb strategy and enhancer-TSS associations from FANTOM5 and 4DGenome if available. Output NRSA generates various kinds of results, including nascent RNA abundance in proximal-promoter and gene body regions, pausing index and pausing significance of known genes, pausing index changes across conditions, as well as identified active enhancers and long eRNAs and their quantification. VISTA enhancer browser--a database of tissue-specific human enhancers. Reprogramming transcription by distinct classes of enhancers functionally defined by eRNA. This assumption is violated if a global expression change occurs. Transcriptional changes in gene body regions S2a and promoter-proximal regions S2b for active genes in Hdac3 KO vs. Clarifying the heterogeneity and complexity of transcriptomes from the view of Cause of Transcription instead of expression profiling.

    EMBnet journal. Although transcriptional changes between promoter-proximal and gene body regions were significantly correlated after Hdac3 knockout, transcripts at gene-body regions accumulated much more slowly than those at promoter-proximal regions, suggesting a dominant effect on enhancing transcription initiation, along with a modest increase in pausing.

    Nat Methods. NRSA is a powerful tool to study enhancer-mediated regulation from nascent transcriptome data, which will greatly facilitate the usage of nascent RNA sequencing techniques and accelerate the study of enhancer-mediated regulation.

Here the authors develop RamDA-seq, a method for full-length total RamDA- seq also detects enhancer RNAs and their cell type-specific. Sequencing nascent RNAs at single-molecule resolution with CoPRO identifies regulatory domain architecture at promoters and enhancers.
    There are two main types of analysis: one for known genes left panels and the other for active enhancers right panels.

    1. If each condition has more than one samples, they should be given as a space-separated list. In addition, comparison of mapping positions to defined transcripts provides an annotation of the CAGE tag.

    2. This eRNA data is important for studying enhancer function, given that previous studies have found eRNA is not mere transcriptional noise from spurious engagement of RNA polymerase with the accessible genomic environment of enhancers [ 626364 ]. Multiple studies showed eRNAs transcription and enhancer-promoter looping E:P looping took precedence over the transcriptional activation of target genes 33
