RNA19(2),141–157(2013), DOI10.1261/rna.035667.112. First-author full byline William R Jeck verified. Abstract and Figures1–4: RNA sequencing with/without RNaseR, enrichment of backsplice junctions and complementary validation. Study-level support for many endogenous circular RNAs, not a universal claim that every resistant transcript is circular or that all circular RNAs are noncoding.
