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

AlaXp is a widely distributed (from bacteria to humans) genome-encoded homolog of the editing domain of alanyl-tRNA synthetases. Editing repairs the confusion of serine and glycine for alanine through clearance of mischarged (with Ser or Gly) tRNA(Ala). Because genome-encoded fragments of editing domains of other synthetases are scarce, the AlaXp redundancy of the editing domain of alanyl-tRNA synthetase is thought to reflect an unusual sensitivity of cells to mistranslation at codons for Ala. Indeed, a small defect in the editing activity of alanyl-tRNA synthetase is causally linked to neurodegeneration in the mouse. Although limited earlier studies demonstrated that AlaXp deacylated mischarged tRNA(Ala) in vitro, the significance of this activity in vivo has not been clear. Here we describe a bacterial system specifically designed to investigate activity of AlaXp in vivo. Serine toxicity, experienced by a strain harboring an editing-defective alanyl-tRNA synthetase, was rescued by an AlaXp-encoding transgene. Rescue was dependent on amino acid residues in AlaXp that are needed for its in vitro catalytic activity. Thus, the editing activity per se of AlaXp was essential for suppressing mistranslation. The results support the idea that the unique widespread distribution of AlaXp arises from the singular difficulties, for translation, poised by alanine.
