Proposal of Chemical Inhibitors That Compete with the Binding of RNA Polymerase II Subunits to Essential GTPases GPN Npa3 and Gpn1.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 Gpn1, Gpn2, and Gpn3 proteins are members of the GTPase GPN family; yeast Npa3 is an orthologue of the human Gpn1 protein. These proteins play a crucial role in the nuclear accumulation of RNA polymerase II, functioning as molecular chaperones. The crystallographic structures of Npa3 reveal open and closed conformations, which are dependent on the bound guanine nucleotide (GMPPCP or GDP, respectively). The open conformation of Npa3 exhibits a hydrophobic pocket proposed to be essential for the recognition and binding of specific peptides of RNA polymerase II, contributing to its biogenesis; however, structural data on these complexes remain unavailable. In this work, we present
