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

We have examined how splicing affects the expression of a range of human and nonhuman genes in vertebrate cells. Although our data demonstrate that splicing invariably enhances the level of gene expression, this positive effect is generally moderate. However, in the case of the human beta-globin gene, splicing is essential for significant protein expression. In the absence of introns, 3' end processing is inefficient, and this appears to be causally linked to a significant decrease in the level of both nuclear and cytoplasmic 3' end-processed RNA. In contrast, splicing appears to only modestly enhance nuclear mRNA export. Consistent with this observation, intronless beta-globin gene expression was only partially rescued by the insertion of retroviral nuclear mRNA export elements. Surprisingly, in the case of the highly intron dependent beta-globin gene, the mRNA that did reach the cytoplasm was also only inefficiently translated if it derived from an intronless expression plasmid. Together, these data argue that splicing can increase gene expression by enhancing mRNA 3' end processing, and hence, mRNA production. Moreover, in the case of the highly intron-dependent beta-globin gene, splicing also significantly enhanced the translational utilization of cytoplasmic beta-globin mRNAs.
