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 characterized transcripts synthesized in vivo by bacteriophage T7 RNA polymerase to investigate yeast mRNA processing. T7 transcripts are not capped, consistent with capping being tightly coupled to RNA polymerase II (pol II) transcription. In contrast to higher eukaryotic non-pol II transcripts, yeast T7 transcripts are spliced as well as cleaved and polyadenylated. However, T7 and pol II transcripts are affected differently in cleavage and polyadenylation mutant strains, indicating that pol II may have a role in yeast 3' end formation. T7 transcripts with 3' ends directed by a polyadenylation signal are exported from the nucleus, and this export is dependent on the canonical cleavage and polyadenylation machinery. Importantly, transcripts with T7 terminator-directed 3' ends are unadenylated and predominantly nuclear in wild-type cells. Our results suggest that transcription by pol II is required for neither the nuclear export of an in vivo-transcribed mRNA nor for the retention of transcripts with aberrant 3' ends. Moreover, proper 3' end formation may be necessary and sufficient to promote mRNA export in yeast.
