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

Epithelial-mesenchymal transition (EMT), a tightly regulated process that is critical for development, is frequently re-activated during cancer metastasis and recurrence. We reported previously that CD44 isoform switching is critical for EMT and showed that the splicing factor ESRP1 inhibits CD44 isoform switching during EMT. However, the mechanism by which ESRP1 is regulated during EMT has not been fully understood. Here we show that the transcription repressor Snail binds to E-boxes in the ESRP1 promoter, causing repression of the ESRP1 gene. Biochemically, we define the mechanism by which ESRP1 regulates CD44 alternative splicing: ESRP1 binds to the intronic region flanking a CD44 variable exon and causes increased variable exon inclusion. We further show that ectopically expressing ESRP1 inhibits Snail-induced EMT, suggesting that down-regulation of ESRP1 is required for function by Snail in EMT. Together, these data reveal how the transcription factor Snail mediates EMT through regulation of a splicing factor.
