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

Exon 3 of the human apolipoprotein A-II (apoA-II) gene is efficiently included in the mRNA although its acceptor site is significantly weak because of a peculiar (GU)16 tract instead of a canonical polypyrimidine tract within the intron 2/exon 3 junction. Our previous studies demonstrated that the SR proteins ASF/SF2 and SC35 bind specifically an exonic splicing enhancer (ESE) within exon 3 and promote exon 3 splicing. In the present study, we show that the ESE is necessary only in the proper context. In addition, we have characterized two novel sequences in the flanking introns that modulate apoA-II exon 3 splicing. There is a G-rich element in intron 2 that interacts with hnRNPH1 and inhibits exon 3 splicing. The second is a purine rich region in intron 3 that binds SRp40 and SRp55 and promotes exon 3 inclusion in mRNA. We have also found that the (GU) repeats in the apoA-II context bind the splicing factor TDP-43 and interfere with exon 3 definition. Significantly, blocking of TDP-43 expression by small interfering RNA overrides the need for all the other cis-acting elements making exon 3 inclusion constitutive even in the presence of disrupted exonic and intronic enhancers. Altogether, our results suggest that exonic and intronic enhancers have evolved to balance the negative effects of the two silencers located in intron 2 and hence rescue the constitutive exon 3 inclusion in apoA-II mRNA.
