A portable poison exon for small-molecule control of mammalian gene expression.
Article in Nature methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The ability to precisely control gene expression using small-molecule drugs is a valuable tool in research and has important therapeutic potential. However, existing systems are often limited by the toxicity of the drugs and the need to alter gene sequences or endogenous regulatory elements. Here, we introduce Cyclone (acyclovir-controlled poison exon), an acyclovir-controlled poison exon cassette that can be used for small-molecule control of both transgene and endogenous gene expression. Cyclone is a portable 'intron-poison exon-intron' element that can be inserted into nearly any gene and is completely removed upon acyclovir treatment, leaving the native transcript intact. Cyclone offers tunable, reversible gene expression with nearly undetectable background and a ~295-fold activation. We also present Pac-Cyclone, a cassette that simplifies the generation of cell lines with acyclovir-controlled endogenous gene expression. Finally, we demonstrate the programmability of Cyclone, underscoring its potential for developing diverse genetic circuits controlled by various ligands.
