1 · What the graph read from it

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.

2 · The registry

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

mRNA surveillance pathways selectively clear defective mRNAs from the cell. As such, these pathways serve as important modifiers of genetic disorders. Nonsense-mediated decay (NMD), the most intensively studied surveillance pathway, recognizes mRNAs with premature termination codons (PTCs). In mammalian systems the location of a PTC more than 50 nucleotides 5' to the terminal exon-exon junction is a critical determinant of NMD. However, mRNAs with nonsense codons that fulfill this requirement but are located very early in the open reading frame can effectively evade NMD. The unexpected resistance of such mRNAs with AUG-proximal PTCs to accelerated decay suggests that important determinants of NMD remain to be identified. Here, we report that an NMD-sensitive mRNA can be stabilized by artificially tethering the cytoplasmic poly(A) binding protein 1, PABPC1, at a PTC-proximal position. Remarkably, the data further suggest that NMD of an mRNA with an AUG-proximal PTC can also be repressed by PABPC1, which might be brought into proximity with the PTC during cap-dependent translation and 43S scanning. These results reveal a novel parameter of NMD in mammalian cells that can account for the stability of mRNAs with AUG-proximal PTCs. These findings serve to expand current mechanistic models of NMD and mRNA translation.
