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

Peroxiredoxin 6 (Prdx6), a bifunctional protein with GSH peroxidase and lysosomal-type phospholipase A(2) activities, has been localized to both cytosolic and acidic compartments (lamellar bodies and lysosomes) in lung alveolar epithelium. We postulate that Prdx6 subcellular localization affects the balance between the two activities. Immunostaining localized Prdx6 to lysosome-related organelles in the MLE12 and A549 alveolar epithelial cell lines. Inhibition of trafficking by brefeldin A indicated processing of the protein through the vesicular pathway. Trafficking of Prdx6 was decreased by inhibitors of PKC, ERK, and p38 MAPK. Immunocytochemistry, immunoprecipitation, and an in situ proximity ligation assay (Duolink) showed that binding of the lysosomal targeting sequence of Prdx6 (amino acids 31-40) to 14-3-3ε was dependent on activity of PKC, ERK, and p38 MAPK. Knockdown of 14-3-3ε with siRNA inhibited the lysosomal targeting of Prdx6. In vitro study with recombinant proteins by pull-down assay and surface plasmon resonance confirmed the interaction of Prdx6 and 14-3-3ε. These findings suggest that ERK and p38 MAPK regulate subcellular localization of Prdx6 by activation of 14-3-3ε as a chaperone protein, resulting in its translocation to acidic organelles.
