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

Although picornavirus RNA genomes contain a 3'-terminal poly(A) tract that is critical for their replication, the impact of encephalomyocarditis virus (EMCV) infection on the host poly(A)-binding protein (PABP) remains unknown. Here, we establish that EMCV infection stimulates site-specific PABP proteolysis, resulting in accumulation of a 45-kDa N-terminal PABP fragment in virus-infected cells. Expression of a functional EMCV 3C proteinase was necessary and sufficient to stimulate PABP cleavage in uninfected cells, and bacterially expressed 3C cleaved recombinant PABP in vitro in the absence of any virus-encoded or eukaryotic cellular cofactors. N-terminal sequencing of the resulting C-terminal PABP fragment identified a 3C(pro) cleavage site on PABP between amino acids Q437 and G438, severing the C-terminal protein-interacting domain from the N-terminal RNA binding fragment. Single amino acid substitution mutants with changes at Q437 were resistant to 3C(pro) cleavage in vitro and in vivo, validating that this is the sole detectable PABP cleavage site. Finally, while ongoing protein synthesis was not detectably altered in EMCV-infected cells expressing a cleavage-resistant PABP variant, viral RNA synthesis and infectious virus production were both reduced. Together, these results establish that the EMCV 3C proteinase mediates site-specific PABP cleavage and demonstrate that PABP cleavage by 3C regulates EMCV replication.
