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

Transforming growth factor-β (TGF-β) exhibits growth inhibitory effects on various types of tumor cells, including B-cell lymphoma cells. In the present study, the role of TGF-β in the survival of Epstein-Barr virus-negative B-cell lymphoma Ramos cells was investigated. As TGF-β-induced apoptosis of Ramos cells in vitro and in vivo, we attempted to identify novel target gene(s) responsible for their survival. Oligonucleotide microarray analysis and chromatin immunoprecipitation revealed that Smad proteins directly regulated the transcription of membrane-spanning 4-domains, subfamily A, member 1 (MS4A1), also known as CD20, in Ramos cells upon TGF-β stimulation. In addition, immunohistochemical analysis using clinical samples from B-cell lymphoma patients showed an inverse correlation between the expression of MS4A1/CD20 and phosphorylation of Smad3. Although knockdown of MS4A1/CD20 in Ramos cells resulted in an increase of apoptotic cells, Ramos cells stably expressing MS4A1/CD20 were resistant to TGF-β-induced apoptosis. This suggests that MS4A1/CD20 is responsible for TGF-β-induced apoptosis of B-cell lymphoma cells. Moreover, downregulation of MS4A1/CD20 by TGF-β attenuated the effects of the monoclonal anti-MS4A1/CD20 antibody, rituximab, on Ramos cells. Our findings suggest that the sensitivity of B-cell lymphoma cells to rituximab may be affected by TGF-β signaling.
