  1. ...involving the coordinated action of transcription factors, chromatin remodelers, and RNA polymerase, which determine where and when transcription begins. Accurately mapping and quantifying transcription start sites (TSSs) from nascently transcribed RNAs remains a key area of interest, as it provides...
  2. .... Whereas much research has focused on the initiation of transcription, regulation of elongation plays an important role not only in transcription dynamics but also in cotranscriptional RNA processing and stability. Despite advances in high-throughput approaches for global quantification of RNA polymerase...
  3. ...structures to impede DNA and RNA polymerase progression in vitro, enabling -wide or transcriptome-wide high-resolution detection of putative DNA and RNA G4s through high-throughput sequencing (Chambers et al. 2015; Kwok et al. 2016; Marsico et al. 2019; Zhao et al. 2022). To detect G4s in vivo...
  4. ...are flash-isolated from cells, depriving them of ribonucleotide substrates for transcription. This stalls RNA polymerases on genes that were in the process of being transcribed. Subsequently, transcription is restarted and allowed to run to completion by adding exogenous-labeled ribonucleotides...

  5. ...also considered that the direction of regulation may not be the same across a regulatory cascade or pathway. For example, although activators typically promote gene expression by facilitating the recruitment of RNA polymerase and transcriptional machinery, their effects on downstream targets can...
  6. ...integrated analyses of single-cell RNA-seq data from multiple human tissues and organs. Single-cell epigenomic data further indicate that the expression is likely driven by an alternative promoter at the end of the first exon, resulting in at least one shorter transcript (referred to as sXIST) that is active...
  7. ...@bcm.eduAbstractThe vast majority of protein-coding genes in the human produce multiple mRNA isoforms through alternative splicing, significantly enhancing the complexity of the transcriptome and proteome. To establish an efficient method for characterizing transcript isoforms within tissue samples, we conducted...
  8. ...sequencing by replacing the standard DNA polymerase with a reverse transcriptase (Vilfan et al. 2013), although this approach has not been widely adopted. Nanopore direct RNA sequencing has made it possible to directly sequence full-length native RNA molecules without reverse transcription and amplification...
  9. ...expression (pre-mRNA), MYC signal at transcription start sites (MYC TSS Share), RNA Pol II signal at transcription start sites (RNAP_TSS), gene body regions (RNAP_GB), transcription end sites (RNAP_TES), mRNA expression (mature), synthesis rates (synthesis), degradation rates (degradation), and processing...
  10. ...expression can be quantified directly from transcript fragments present in sRNA-seq experiments. We analyze studies containing matched total RNA and small RNA from four human tissues and recover transcript fragments from the sRNA-seq data sets. We find that the expression levels of protein-coding gene...
