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

Gene expression in eukaryotes is often enhanced by the presence of introns. Depending on the specific gene, this enhancement can be minor or very large and occurs at both the transcriptional and post-transcriptional levels. The Arabidopsis ERECTA gene contains 27 exons encoding a receptor-like kinase that promotes cell proliferation and inhibits cell differentiation in above-ground plant organs. The expression of ERECTA very strongly depends on the presence of introns. The intronless ERECTA gene does not rescue the phenotype of erecta mutant plants and produces about 500-900 times less protein compared with the identical construct containing introns. This result is somewhat surprising as the region upstream of the ERECTA coding sequence effectively promotes the expression of extraneous genes. Here, we demonstrate that introns are essential for ERECTA mRNA accumulation and, to a lesser extent, for mRNA utilization in translation. Since mRNA produced by intronless ERECTA is degraded at the 3' end, we speculate that introns increase mRNA accumulation through increasing its stability at least in part. No individual intron is absolutely necessary for ERECTA expression, but rather multiple introns in specific locations increase ERECTA expression in an additive manner. The ability of introns to promote ERECTA expression might be linked to the process of splicing and not to a particular intron sequence.
