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

Malignant B cells rely on B cell receptor (BCR) signals for their survival and growth. Besides the Immunoglobulin M (IgM) BCR, lymphoma cells can also express non-IgM (IgG) BCRs; however, the role of IgG BCRs in malignant B cell is not well understood. Here, we report poorer disease outcomes in diffuse large B cell lymphoma (DLBCL) expressing high IgM versus those expressing IgG1. Using isogenic lymphoma cells expressing distinct BCRs, we found that IgM expressing cells strongly outcompete their IgG1 counterparts. Mechanistically, IgG1 BCR is associated with a dysfunctional mitochondrial state and reduced cell survival. We show that mitochondrial dysfunction is triggered by accentuated calcium responses downstream of IgG1 BCR. Genetic reversal of IgG1 to IgM, pharmacological dampening of calcium signaling, or treatment with interleukin-21 can correct mitochondrial defects and rescue IgG1 survival. Our findings demonstrate that distinct BCR isotypes are inherently unique and can differentially affect B cell lymphoma pathogenesis.
