Short Repeat Ribonucleic Acid Reduces Cytotoxicity by Preventing the Aggregation of TDP-43 and Its 25 KDa Carboxy-Terminal Fragment.
Article in JACS Au, 2024. 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
TAR DNA/RNA-binding protein 43 kDa (TDP-43) proteinopathy is a hallmark of neurodegenerative disorders, such as amyotrophic lateral sclerosis, in which cytoplasmic aggregates containing TDP-43 and its C-terminal fragments, such as TDP-25, are observed in degenerative neuronal cells. However, few reports have focused on small molecules that can reduce their aggregation and cytotoxicity. Here, we show that short RNA repeats of GGGGCC and AAAAUU are aggregation suppressors of TDP-43 and TDP-25. TDP-25 interacts with these RNAs, as well as TDP-43, despite the lack of major RNA-recognition motifs using fluorescence cross-correlation spectroscopy. Expression of these RNAs significantly decreases the number of cells harboring cytoplasmic aggregates of TDP-43 and TDP-25 and ameliorates cell death by TDP-25 and mislocalized TDP-43 without altering the cellular transcriptome of molecular chaperones. Consequently, short RNA repeats of GGGGCC and AAAAUU can maintain proteostasis by preventing the aggregation of TDP-43 and TDP-25.
