This study explored the. From the RNA-seq data, a comparison of lncRNA expression profile between the 7 pairs of iCCA and adjacent normal tissues identified 230 lncRNAs that were differentially expressed (fold change ≥ 4, P < 0. Single cell RNA sequencing (scRNA-seq) is one of the widely used techniques, which can reveal the transcriptome (including mRNAs and lncRNAs) heterogeneity of different cells (Fig. In the past 10 years,. Eukaryotic genomes are pervasively transcribed. R.
