Decoy DNA Protects Molecular Tension Probes from DNase Degradation.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
DNA-based molecular probes are essential tools for visualizing and quantifying mechanotransduction at the single-molecule level. However, their application in live-cell environments is severely limited by DNase-mediated degradation, which shortens probe lifespan and introduces false-positive signals. Here, we present a decoy DNA strategy where an excess of unmodified double-stranded DNA competitively binds DNases, effectively preserving functional DNA probes. This approach extends probe stability from 1-2 h to beyond 24 h, substantially improving signal integrity in live-cell tension imaging. In contrast to structurally modified nucleic acids, decoy DNA can be readily applied to existing DNA probe systems, enabling seamless integration without the need for additional validation or calibration. This cost-effective and scalable strategy provides a generalizable framework for stabilizing DNA-based molecular tools in DNase-rich environments, enabling high-precision mechanobiology studies across diverse cell types and extended experiment durations.
