A genome-wide circular RNA transcriptome in Rat (original) (raw)

Biology Methods and Protocols

Abstract

Circular RNAs are a novel class of non-coding RNAs that backsplice from 5' donor site and 3' acceptor sites to form a circular structure. A number of circRNAs have been discovered in model organisms including human, mouse, Drosophila, among other organisms. There are a few candidate-based studies on circular RNAs in rat, a well-studied model organism as well. A number of pipelines have been published to identify the back splice junctions for the discovery of circRNAs but studies comparing these tools have suggested that a combination of tools would be a better approach to identify high-confidence circular RNAs. The availability of a recent dataset of transcriptomes encompassing 11 tissues, 4 developmental stages and 2 genders motivated us to explore the landscape of circular RNAs in the organism in this context. In order to understand the difference among different pipelines, we employed 5 different combinations of tools to identify circular RNAs from the dataset. We compare...
