CircRNAwrap - a flexible pipeline for circRNA identification, transcript prediction, and abundance estimation

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• Circular RNAs (circRNAs) are a class of RNA molecules formed by a unique backsplicing mechanism.
• The study of circRNAs using RNA-Seq data offers a genome-wide perspective on endogenous circular transcripts.
• Current algorithms for circRNA analysis have limitations, and methods for predicting and validating exon composition are still evolving.

Purpose of the Study:

• To evaluate the effectiveness of existing circRNA analysis tools using both collected and simulated data.
• To develop and present a comprehensive circRNA workflow named circRNAwrap.
• To provide a novel protocol that aids researchers in studying circRNA biology.

Main Methods:

• Performance assessment of current circRNA analysis algorithms.
• Utilization of both real-world and simulated RNA-Seq datasets for testing.
• Development and application of the circRNAwrap workflow.

Main Results:

• Existing circRNA analysis tools showed limited effectiveness on the tested datasets.
• The circRNAwrap protocol was applied to various datasets, demonstrating its utility.
• The study provides a benchmark for evaluating circRNA analysis tools.

Conclusions:

• The circRNAwrap protocol offers a valuable resource for researchers investigating circRNA biology.
• This workflow enhances the analysis of circRNAs from RNA-Seq data.
• Further development of circRNA analysis methods is warranted.
