The T cell receptor beta enhancer promotes access and pairing of Dbeta and Jbeta gene segments during V(D)J recombination.

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.
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 precise function of cis elements in regulating V(D)J recombination is still controversial. Here, we determined the effect of inactivation of the TCRbeta enhancer (Ebeta) on cleavage and rearrangement of Dbeta1, Dbeta2, Jbeta1, and Jbeta2 gene segments in CD4-CD8- [double-negative (DN)] and CD4+CD8+ [double-positive (DP)] thymocytes. In Ebeta-deficient mice, (i) Dbeta1 rearrangements were more severely impaired than Dbeta2 rearrangements; (ii) most of the Dbeta and Jbeta cleavages and rearrangements occurred in DP, rather than in DN, thymocytes; and (iii) most of the 3' Dbeta1 cleavages were coupled to 5' Dbeta2 cleavages instead of to Jbeta cleavages, resulting in nonstandard Dbeta1-Dbeta2-Jbeta2 joints. These findings suggest that the Ebeta regulates TCRbeta rearrangement by promoting accessibility of Dbeta and Jbeta gene segments in DN thymocytes and proper pairing between Dbeta1 and Jbeta gene segments for cleavage and joining in DP thymocytes.
