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

Rapid analysis of mechanisms that regulate V(D)J recombination has been hampered by the lack of appropriate cell systems that reproduce aspects of normal prelymphocyte physiology in which the recombinase is activated, accessible antigen receptor loci are rearranged, and rearrangement status is fixed by termination of recombinase expression. To generate such a system, we introduced heat shock-inducible V(D)J recombination-activating genes (RAG) 1 and 2 into a recombinationally inert B-cell line. Heat shock treatment of these cells rapidly induced high levels of RAG transcripts and RAG proteins that were accompanied by a parallel induction of V(D)J recombinase activity, strongly suggesting that RAG proteins have a primary role in V(D)J recombination. Within hours after induction, these cells began to rearrange chromosomally integrated V(D)J recombination substrates but only if the substrates contained an active transcriptional enhancer; substrates lacking an enhancer were not efficiently rearranged. Activities necessary to target integrated substrates for rearrangement were provided by two separate lymphoid-specific transcriptional enhancers, as well as an active nonlymphoid enhancer, unequivocally demonstrating that such elements enhance both transcription and V(D)J recombinational accessibility.
