Conservation of mRNA operon formation in control of the heat shock response in mammalian cells.
Article in Science advances, 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
Prokaryotes use polycistronic transcription (operons) to express multiple messenger RNAs (mRNAs) from a single promoter to coexpress functionally related genes. However, how do eukaryotes, which express monocistronic messages, achieve the same regulation? Previously, we demonstrated that yeast uses RNA operons, i.e., mRNAs assembled in trans (transperons), to control multiple cellular pathways such as the heat shock response (HSR). As the HSR is conserved from yeast to mammals, we used single-molecule RNA labeling and pulldown techniques to demonstrate that mammalian heat shock protein (HSP) mRNAs also form operons upon transcription during heat stress. HSP RNA operon formation is dependent on the heat shock factor 1 transcription factor and intra- and interchromosomal interactions between the HSP genes. Work in yeast identified a conserved RNA sequence motif and histone H4 functions that act downstream thereof to regulate transperon assembly. Our work highlights the evolutionarily conserved regulation of the HSR and for RNA operons in eukaryotic gene regulation.
