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

In eukaryotic cells, it is generally accepted that protein synthesis is compartmentalized; soluble proteins are synthesized on free ribosomes, whereas secretory and membrane proteins are synthesized on endoplasmic reticulum (ER)-bound ribosomes. The partitioning of mRNAs that accompanies such compartmentalization arises early in protein synthesis, when ribosomes engaged in the translation of mRNAs encoding signal-sequence-bearing proteins are targeted to the ER. In this report, we use multiple cell fractionation protocols, in combination with cDNA microarray, nuclease protection, and Northern blot analyses, to assess the distribution of mRNAs between free and ER-bound ribosomes. We find a broad representation of mRNAs encoding soluble proteins in the ER fraction, with a subset of such mRNAs displaying substantial ER partitioning. In addition, we present evidence that membrane-bound ribosomes engage in the translation of mRNAs encoding soluble proteins. Single-cell in situ hybridization analysis of the subcellular distribution of mRNAs encoding ER-localized and soluble proteins identify two overall patterns of mRNA distribution in the cell-endoplasmic reticular and cytosolic. However, both partitioning patterns include a distinct perinuclear component. These results identify previously unappreciated roles for membrane-bound ribosomes in the subcellular compartmentalization of protein synthesis and indicate possible functions for the perinuclear membrane domain in mRNA sorting in the cell.
