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 role of T cell receptor alpha enhancer (E alpha) cis-acting elements in the developmental regulation of VDJ recombination at the TCR alpha/delta locus was examined in transgenic mice containing variants of a minilocus VDJ recombination substrate. We demonstrate that the 116-bp T alpha 1,2 core enhancer fragment of the 1.4-kb E alpha is sufficient to activate the enhancer-dependent step of minilocus rearrangement, and that within T alpha 1,2, intact binding sites for TCF/LEF and Ets family transcription factors are essential. Although minilocus rearrangement under the control of the 1.4-kb E alpha initiates at fetal day 16.5 and is strictly limited to alpha beta T cells, we find that rearrangement under the control of T alpha 1,2 initiates slightly earlier during ontogeny and occurs in both gamma delta and alpha beta T cells. We conclude that the core fragment of E alpha can establish accessibility to the recombinase in developing thymocytes in vivo in a fashion that is dependent on the binding of TCF/LEF and Ets family transcription factors, but that these and other factors that bind to the E alpha core cannot account for the precise developmental onset of accessibility that is provided by the intact E alpha. Rather, our data suggests a critical role for factors that bind E alpha outside of the core T alpha 1,2 region in establishing the precise developmental onset of TCR alpha rearrangement in vivo.
