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

To analyze the relationship between antisense transcription and alternative splicing, we developed a computational approach for the detection of antisense-correlated exon splicing events using Affymetrix exon array data. Our analysis of expression data from 176 lymphoblastoid cell lines revealed that the majority of expressed sense-antisense genes exhibited alternative splicing events that were correlated to the expression of the antisense gene. Most of these events occurred in areas of sense-antisense (SAS) gene overlap, which were significantly enriched in both exons and nucleosome occupancy levels relative to nonoverlapping regions of the same genes. Nucleosome occupancy was highly correlated with Pol II abundance across overlapping regions and with concomitant increases in local alternative exon usage. These results are consistent with an antisense transcription-mediated mechanism of splicing regulation in normal human cells. A comparison of the prevalence of antisense-correlated splicing events between individuals of Mormon versus African descent revealed population-specific events that may indicate the continued evolution of new SAS loci. Furthermore, the presence of antisense transcription was correlated to alternative splicing across multiple metazoan species, suggesting that it may be a conserved mechanism contributing to splicing regulation.
