Kinetic control of mammalian transcription elongation.
Article in Nature structural & molecular biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Transcription elongation by RNA polymerase II (Pol II) is an integral step in eukaryotic gene expression. The speed of Pol II is controlled by a multitude of elongation factors, but the exact regulatory mechanisms remain incompletely understood, especially for higher eukaryotes. Here we develop a single-molecule platform to visualize the dynamics of individual mammalian transcription elongation complexes (ECs) reconstituted from purified proteins. This platform allows us to follow the elongation and pausing behavior of EC in real time and unambiguously determine the role of each elongation factor in the kinetic control of Pol II. We find that the mammalian EC harbors multiple speed gears dictated by its associated factors and phosphorylation status. Moreover, the elongation factors are not functionally redundant but act hierarchically and synergistically to achieve optimal elongation activity. We propose that such elaborate kinetic regulation underlies the major speed-changing events during the transcription cycle and enables cells to adapt to a changing environment.
