In vitro programmable DNA cleavage by a eukaryotic Argonaute.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
Eukaryotic Argonautes (eAgos) have traditionally been characterized by their ability to utilize RNA guides to identify RNA targets, thereby engaging in post-transcriptional gene silencing pathways. While some eAgos have been demonstrated to use DNA guides for RNA cleavage, the ability of eAgos to cleave DNA targets remains unclear. In this study, we characterized CsAgo, an eAgo protein derived from thermophilic eukaryote Chaetomiumsp. MPI-CAGE-AT-0009, demonstrating a novel ability to cleave both DNA and RNA targets in vitro. Guided by short single-stranded DNA (ssDNA) or RNA, CsAgo exhibits robust RNA cleavage activity at 20-90°C in vitro. CsAgo can effectively cleave ssDNA guided by RNA guides at 20-50°C in vitro. Notably, CsAgo can utilize DNA guides to effectively cleave ssDNA, plasmid double-stranded DNA (dsDNA), and linear dsDNA at ≥80°C in vitro. Based on its ability to cleave dsDNA at high temperatures, CsAgo demonstrates versatility and efficacy in simplifying routine cloning workflows. Additionally, we have developed a CsAgo-based nucleic acid detection method based on a Pyrococcus furiosus Ago-mediated nucleic acid detection method, which exhibits a high sensitivity of six copies/reaction. These results suggest that eAgos include that, in theory, can be utilized for potential DNA-targeting applications. This not only enhances our understanding of eAgos but also expands the toolkit for DNA manipulation.
