A circularly permuted CasRx platform for efficient, site-specific RNA editing.
Article in Nature biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Inactive Cas13 orthologs have been fused to a mutant human ADAR2 deaminase domain at the C terminus to enable programmable adenosine-to-inosine (A-to-I) RNA editing in selected transcripts. Although promising, existing RNA-editing tools generally suffer from a trade-off between efficacy and specificity, and off-target editing remains an unsolved problem. Here we describe the development of an optimized RNA-editing platform by rational protein engineering, CasRx-based Programmable Editing of RNA Technology (xPERT). We demonstrate that the topological rearrangement of a CasRx K940L mutant by circular permutation results in a robust scaffold for the tethering of a deaminase domain. We benchmark our tool against the REPAIR system and show that xPERT exhibits strong on-target activity like REPAIRv1 but low off-target editing like REPAIRv2. Our xPERT platform can be used to alter RNA sequence information without risking genome damage, effect temporary cellular changes and customize protein function.
