Summary

In this study we report a comparative, transcriptome-wide analysis of CRISPR/Cas-based RNA-editing technologies in HEK293T cells. Targeted RNA editing technologies hold great process in the area of post-transcriptional genomic engineering and impermanent therapeutic correction of disease-causing variants, though off-target editing events still remain a concern. Here, we perform paired-end poly(A)+ purified RNA-seq to characterize transcriptome-wide in HEK293T cells transfected with catalytically-dead Cas9-, Cas13b, or Cas13d fused to human ADAR2 deaminase domain containing a hyperactive editing mutation (E488Q) along with either CYFIP2¬-targeting or non-targeting gRNA, in duplicate. We find that all technologies tested introduced widespread but distinct off-target mutations in the transcriptome, with the majority of edits occurring in 3’UTR and CDS regions of genes. Many of these edits, however, were in transcripts with low coverage, with the majority of editing rates being below 20%. This study is the first to characterize Cas-based RNA editing technologies in a direct manner, and reveals the relative similarity of currently available methods both in terms of on-target and off-target efficacy.

Overall Design

Examination of mRNA profiles of HEK293T cells 48 hours after transfection with dCas9-, dCas13b, or dCas13d-ADAR2(E488Q) fusions with either CYFIP2¬-targeting or NT gRNA

View Data Processing
Processing steps for GSE152684
  1. Raw reads were adapter-trimmed using Cutadapt (version 1.14)
  2. Sequenced reads were aligned to hg19 genome using STAR (version 2.5.2b) and sorted using samtools (version 1.5)
  3. Gene counts were quantified from sorted BAM files using featureCounts (version 1.5.0) of the Subread (Liao et al., Nucleic Acids Research 2013) package using "gene" as a metafeature.
  4. Annotated gene length and gene counts were subsequently used to calculate transcript per-million (TPM) for each gene in each library.
  5. For downsampling prior to downstream editing analysis, samtools view -bs INT.FRAC was used for proportional downsampling of read pairs to achieve sampling depth between 15-35 million aligned reads
  6. Aligned BAM files were run through SAILOR (v1.0.4) using the following parameters-- min_variant_coverage: 5, alpha: 0, beta: 0, edit_fraction: 0.01
  7. BED files that are output corresponding to positive and negative strands of the genome from SAILOR are combined into one BED file and filtered based upon confidence score (Washburn et al., Cell Reports 2014)
  8. Recurrent sites between replicates were determined using pybedtools (version 0.8.0) intersect with the following options: wo=True, s=True
