The reverse transcriptase domain of prime editors contributes to DNA repair in mammalian cells.
Article in Nature biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Reverse transcriptase (RT) has been shown to play a role in double-strand break repair in bacteria, yet the impact of the RT component of prime editors (PEs) on normal mammalian cellular functions is unclear. Here we show that overexpressed RT or PE increases short insertions and diminishes homology-directed repair following Cas9 cleavage at multiple loci in multiple cell lines. Live-cell imaging shows that RT and PEs are rapidly recruited to laser-induced DNA damage sites and promote endogenous repair, independent of known DNA damage sensors. Interestingly, RT-mCherry partially impairs green fluorescent protein-PARP1 recruitment. A compact PE without an RNase H domain shows reduced DNA repair activity and may therefore be more suitable for clinical application. These data reveal a role for untethered RT or the RT domain of PEs in the repair of chromosomal breaks, calling for evaluation of the long-term effect of PEs and retroviral RT in mammalian cells.
