Most transcriptome studies involve sequencing and quantification of steady-state mRNA by isolating and sequencing poly (A) RNA. Although this type of sequencing data is informative to determine steady-state mRNA levels, it does not provide information on transcriptional output and thus may not always reflect changes in transcriptional regulation of gene expression . Furthermore, sequencing poly (A) RNA may miss transcribed regions of the genome not usually modified by polyadenylation which includes many long non-coding RNAs including enhancer RNA (eRNA). Here, we describe nuclear RNA sequencing (nucRNA-seq) which investigates the transcriptional landscape through sequencing and quantification of nuclear RNAs which are both unspliced and spliced transcripts for protein-coding genes and nuclear-retained long non-coding RNAs. © 2021.
