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

While the structure of mature ribosomes is analyzed in atomic detail considerably less is known about their assembly process in living cells. This is mainly due to technical and conceptual hurdles. To analyze ribosome assembly in vivo, we designed and engineered an Escherichiacoli strain--using chromosomal gene knock-in techniques--that harbors large and small ribosomal subunits labeled with the fluorescent proteins EGFP and mCherry, respectively. A thorough characterization of this reporter strain revealed that its growth properties and translation apparatus were wild-type like. Alterations in the ratio of EGFP over mCherry fluorescence are supposed to indicate ribosome assembly defects. To provide proof of principle, subunit specific assembly defects were provoked and could be identified by both manual and fully automated fluorometric in vivo assays. This is to our knowledge the first methodology that directly detects ribosome assembly defects in vivo in a high-throughput compatible format. Screening of knock-out collections and small molecule libraries will allow identification of new ribosome assembly factors and possible inhibitors.
