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 random nature of T-cell receptor-β (TCR-β) recombination needed to generate immunological diversity dictates that two-thirds of alleles will be out-of-frame. Transcripts derived from nonproductive rearrangements are cleared by the nonsense-mediated mRNA decay (NMD) pathway, the process by which cells selectively degrade transcripts harboring premature termination codons. Here, we demonstrate that the fetal thymus in transgenic mice that ubiquitously express a dominant-negative form of Rent1/hUpf1, an essential trans-effector of NMD, shows decreased cell number, reduced CD4CD8 double-positive thymocytes, diminished expression of TCR-β, and increased expression of CD25, suggesting a defect in pre-TCR signaling. Transgenic fetal thymocytes also demonstrated diminished endogenous Vβ-to-DβJβ rearrangements, whereas Dβ-to-Jβ rearrangements were unperturbed, suggesting that inhibition of NMD induces premature shut-off of TCR-β rearrangement. Developmental arrest of thymocytes is prevented by the introduction of a fully rearranged TCR-β transgene that precludes generation of out-of-frame transcripts, suggesting direct mRNA-mediated trans-dominant effects. These data document that NMD has been functionally incorporated into developmental programs during eukaryotic evolution.
