GSE98664: Single-cell full-length total RNA sequencing uncovers dynamics of recursive splicing and enhancer RNAs
Bulk RNA sequencing
We report a novel single-cell total RNA-seq method, RamDA-seq, by combining a novel reverse transcription (RT) technology, RT with random displacement amplification (RT-RamDA), and not-so-random (NSR) primers. RT-RamDA provides global cDNA amplification directly from RNA during RT without any universal adopters, which benefits RT efficiency, simplification of the procedure, avoiding the step of PCR amplification, and decontamination of genomic DNA. NSR enables random priming while preventing cDNA synthesis from rRNAs. RamDA-seq showed high sensitivity to non-poly(A) RNAs and full-length coverage even for extremely long transcripts (>10 kb). Moreover, RamDA-seq revealed recursive splicing, a multi-step, splicing, within > 300 kbp-long introns. Finally, RamDA-seq enabled the first genome-wide analysis of enhancer RNAs (eRNAs) in single cells. SOURCE: Haruka Ozaki (haruka.ozaki@riken.jp) - Bioinformatics Research Unit RIKEN
