Mammalian Queuosine tRNA Modification Impacts Translation to Enhance Cell Proliferation and MHC-II Expression.
Article in Journal of molecular biology, 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
Queuosine (Q) is a conserved tRNA modification in the wobble anticodon position of tRNAs that read codons of Tyr/His/Asn/Asp. Eukaryotic tRNA Q-modification requires the metabolite queuine - derived from diet or catabolism of the gut microbiome - and a host-genome encoded enzyme complex, QTRT1/QTRT2. tRNA Q-modification has been shown to regulate translational efficiency, but the response of the mammalian transcriptome and tRNAome to tRNA Q-modification in the context of cell proliferation has not been thoroughly investigated. Using cells that differ only in their tRNA Q-modification levels, we found that both human HEK293T cultures and the primary, murine bone marrow-derived dendritic cells (BMDCs) proliferate faster when tRNA Q-modification level is high. We carried out tRNA-seq and mRNA-seq to elucidate the molecular mechanisms underlying this phenotype, revealing distinct tRNA modification and transcriptome changes associated with altered proliferation. In both cell types, the m
