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

Activation-induced (cytidine) deaminase (AID) efficiently introduces multiple and diversified deaminations in immunoglobulin (Ig) variable and switch regions. Here, we review studies of AID, and the APOBEC family member, APOBEC3G, demonstrating that both enzymes introduce multiple deaminations by processive action on single-stranded DNA and that deaminations occur stochastically at hot- and cold-spot targets. In a more detailed analysis of AID, we examine phosphorylation-null mutants, particularly, S38A and S43P. S43P mutant AID has been identified in a patient with hyper-IgM immunodeficiency syndrome. The phosphorylation-null mutants have essentially the same specific activity, processivity and ability to undergo transcription-dependent deamination compared with wild-type (WT) AID. Although the phosphorylation-null mutants still deaminate 5'-WRC hot spots, the mutant deamination spectra differ from WT AID. The mutants strongly prefer two motifs, 5'AGC and 5'GGC, which are disfavoured by WT AID. Differences in deamination specificities can be attributed primarily to the replacement of Ser rather than to the absence of phosphorylation. The 5'GGC motif occurs with exceptionally high frequency on the non-transcribed strand of human switch regions, IgG4 and IgE. The potential for S43P to catalyse large numbers of aberrant deaminations in switch region sequences suggests a possible relationship between non-canonical AID deamination specificity and a loss of antibody diversification.
