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) plays a key role in B cell immunoglobulin (Ig) class switch recombination (CSR) and somatic hypermutation (SHM). We have previously reported that the highly conserved homeodomain HoxC4 transcription factor binds to the Aicda (AID gene) promoter to induce AID expression. Here, we investigated the regulation of HoxC4 transcription by a proliferation-inducing ligand (APRIL) and B cell-activating factor belonging to the TNF family (BAFF) in mouse B cells. APRIL substantially increased both HoxC4 and AID expression, whereas BAFF induced the expression of AID but not HoxC4. To elucidate the underlying mechanisms, we constructed a HoxC4 gene promoter reporter vector and analyzed the promoter induction after APRIL stimulation. APRIL enhanced the HoxC4 promoter activity by 2.3-fold, and this increase disappeared when the second putative NF-κB-binding promoter element (NBE2) was mutated. Based on ChIP assays, we found that NF-κB bound to the HoxC4 promoter NBE2 region. Furthermore, the overexpression of NF-κB augmented the APRIL-induced HoxC4 promoter activity, while the expression of dominant negative-IκBα suppressed it. Taken together, our findings suggest that NF-κB mediates APRIL-induced HoxC4 transcription.
