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

The nonsense-mediated mRNA decay (NMD) pathway degrades mRNAs undergoing premature termination of translation. It has been argued that in human cells, NMD is restricted to a pioneer round of translation initiated on mRNAs associated with the cap-binding complex (CBC) and that the exchange of the CBC for the eIF4F translation initiation complex renders mRNAs immune to NMD. Here, we demonstrate that human mRNAs undergoing eIF4F-dependent translation are not immune to NMD. First, prolonged translation inhibition does not render an NMD substrate resistant to NMD, despite allowing exchange of CBC for eIF4F. Second, eIF4F inhibitors stabilize NMD substrates undergoing cap-dependent translation. Third, the eIF4E-associated pool of an NMD substrate degrades as rapidly as the overall pool of the mRNA. Thus, eIF4F-dependent translation supports NMD in human cells, allowing for the possibility that NMD could be activated upon cellular cues on already translating mRNAs.
