Profiling of circular RNAs in gastric cancer tissues and adjacent normal tissues
Purpose: To investigate the role and mechanism of circRNAs in gastric cancer. Methods: RNA-seq of ribosomal RNA-depleted total RNA and qRT-PCR were performed to screen differential expressed circRNAs between paired gastric cancer tissues and adjacent normal tissues. Results: A total of 57623 distinct circRNAs were identified in these samples, and 35120 of these circRNAs contained at least two independent back-spliced reads in at least two samples. Compared with circBase, we found that there were 29007 matched circRNAs and 28616 novel circRNAs in our study. Overall design: Gastric circRNA profiles of paired gastric cancer tissues and adjacent normal tissues were generated by deep sequencing, using Illumina HiSeq Xten.
