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 mouse c-src gene contains a short neuron-specific exon, N1. To characterize the sequences that regulate N1 splicing, we used a heterologous gene, derived from the human beta-globin gene, containing a short internal exon that is usually skipped by the splicing machinery. Various fragments from the src gene were inserted into the globin substrate to measure their effects on the splicing of the test exon. These clones were transiently expressed in neuronal and nonneuronal cell lines, and the level of exon inclusion was measured by primer extension. Several sequences from the N1 exon region induced the splicing of the heterologous exon. The most powerful effect was seen with a sequence from the intron downstream of the N1 exon. This sequence acted as a strong splicing enhancer, activating splicing of the test exon when placed in the intron downstream. The enhancer was strongest in neuronal LA-N-5 cells but also activated splicing in nonneuronal HEK293 cells. Deletion and linker scanning mutagenesis indicate that the enhancer is made up of multiple smaller elements that must act in combination. One of these elements was identified as the sequence UGCAUG. Three copies of this element can strongly activate splicing of the test exon in LA-N-5 neuroblastoma cells. These component elements of the src splicing enhancer are also apparently involved in the splicing of other short cassette exons.
