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

Humans have two near identical copies of the survival of motor neuron (SMN) gene, SMN1 and SMN2. In spinal muscular atrophy (SMA), SMN2 is not able to compensate for the loss of SMN1 due to an inhibitory mutation at position 6 (C6U mutation in transcript) of exon 7. We have recently shown that C6U creates an extended inhibitory context (Exinct) that causes skipping of exon 7 in SMN2. Previous studies have shown that an exonic splicing enhancer associated with Tra2 (Tra2-ESE) is required for exon 7 inclusion in both SMN1 and SMN2. Here we describe the method of in vivo selection that determined the position-specific role of wild-type nucleotides within the entire exon 7. Our results confirmed the existence of Exinct and revealed the presence of an additional inhibitory tract (3'-Cluster) near the 3'-end of exon 7. We also demonstrate that a single nucleotide substitution at the last position of exon 7 improves the 5' splice site (ss) such that the presence of inhibitory elements (Exinct as well as the 3'-Cluster) and the absence of Tra2-ESE no longer determined exon 7 usage. Our results suggest that the evolutionary conserved weak 5' ss may serve as a mechanism to regulate exon 7 splicing under different physiological contexts. This is the first report in which a functional selection method has been applied to analyze the entire exon. This method offers unparallel advantage for determining the relative strength of splice sites, as well as for identifying the novel exonic cis-elements.
