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 used the Nanopore long-read sequencing platform to demonstrate how amazingly complex the human adenovirus type 2 (Ad2) transcriptome is with a flexible splicing machinery producing a range of novel mRNAs both from the early and late transcription units. In total we report more than 900 alternatively spliced mRNAs produced from the Ad2 transcriptome whereof more than 850 are novel mRNAs. A surprising finding was that more than 50% of all E1A transcripts extended upstream of the previously defined transcriptional start site. The novel start sites mapped close to the inverted terminal repeat (ITR) and within the E1A enhancer region. We speculate that novel promoters or enhancer driven transcription, so-called eRNA transcription, is responsible for producing these novel mRNAs. Their existence was verified by a peptide in the Ad2 proteome that was unique for the E1A ITR mRNA. Although we show a high complexity of alternative splicing from most early and late regions, the E3 region was by far the most complex when expressed at late times of infection. More than 400 alternatively spliced mRNAs were observed in this region alone. These mRNAs included extended L4 mRNAs containing E3 and L5 sequences and readthrough mRNAs combining E3 and L5 sequences. Our findings demonstrate that the virus has a remarkable capacity to produce novel exon combinations, which will offer the virus an evolutionary advantage to change the gene expression repertoire and protein production in an evolving environment.
