The influence of IL-7 V(D)J recombination.
Article in Immunology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 influence of interleukin-7 (IL-7) on V(D)J recombination was investigated directly in the V(D)J recombination competent pre-B-cell line 38B9. The addition of IL-7 to the medium reduced the V(D)J recombination rate by 52-64%. This reduction was insensitive to the addition of cyclosporin A, indicating that the repression by IL-7 is not mediated by phosphatase 2B. The repression mechanism of IL-7 did not synergize with those of the protein kinase C activator 12-O-Tetradecanoylphorbol-13-acetate (TPA) and the intracellular Ca2+ mobilizer thapsigargin. The actin of IL-7 blocked by the addition of the protein kinase A stimulator caffeine and the synthetic glucocorticoid dexamethasone. IL-7 did not change the m-RNA levels of the V(D)J recombination activating genes RAG-1 and RAG-2, therefore IL-7 must exert its influence on V(D)J recombination either by post-transcriptional regulation of the RAG genes or by the regulation of other genes that are involved in V(D)J recombination. Although IL-7 may be necessary for the induction of and maintenance of V(D)J recombination during some stages of lymphocyte precursor development, it reduces the V(D)J recombination activity in pre-B cells.
