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

The mammalian thyroid hormone receptor gene c-erbAalpha gives rise to two mRNAs that code for distinct isoforms, TRalpha1 and TRalpha2, with antagonistic functions. Alternative processing of these mRNAs involves the mutually exclusive use of a TRalpha1-specific polyadenylation site or TRalpha2-specific 5' splice site. A previous investigation of TRalpha minigene expression defined a critical role for the TRalpha2 5' splice site in directing alternative processing. Mutational analysis reported here shows that purine residues within a highly conserved intronic element, SEa2, enhance splicing of TRalpha2 in vitro as well as in vivo. Although SEalpha2 is located within the intron of TRalpha2 mRNA, it activates splicing of a heterologous dsx pre-mRNA when located in the downstream exon. Competition with wild-type and mutant RNAs indicates that SEalpha2 functions by binding trans-acting factors in HeLa nuclear extract. Protein-RNA crosslinking identifies several proteins, including SF2/ASF and hnRNP H, that bind specifically to SEalpha2. SEalpha2 also includes an element resembling a 5' splice site consensus sequence that is critical for splicing enhancer activity. Mutations within this pseudo-5' splice site sequence have a dramatic effect on splicing and protein binding. Thus SEa2 and its associated factors are required for splicing of TRalpha2 pre-mRNA.
