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

M14T is a virally transformed immature T-cell line which continues to rearrange its T-cell antigen receptor (TCR) alpha-chain genes in vitro and thus represents a dynamic system for studying TCR assembly. In an effort to investigate whether the TCR alpha locus is accessible for V(D)J rearrangement events, we examined M14T cells for the presence of germ line TCR alpha transcripts. Several unrearranged V alpha segments were found to be transcriptionally active in M14T cells. By comparison, germ line V alpha transcripts are absent in nonlymphoid and pro-T-cell lines and barely detectable in mature T-cell lines, suggesting that this phenomenon is likely stage and tissue specific. We demonstrate a perfect correlation between transcriptionally active V alpha segments and their involvement in ongoing V alpha-to-J alpha rearrangements. In addition, data suggesting that the unrearranged J alpha locus is also transcriptionally active in the M14T line are presented. Furthermore, the recombination-activating genes RAG-1 and RAG-2 are differentially expressed, with RAG-2 detectable only by polymerase chain reaction, implying that very low levels of one of these gene products are sufficient to complement the other to facilitate VJ rearrangements. These findings provide the first direct evidence for an accessibility model of antigen receptor rearrangement in T cells.
