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

backgroundDiffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma that arises from malignant transformation of B lymphocytes. Outcome of patients with DLBCL has been significantly improved by rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy, which is regarded "gold standard" of DLBCL therapy. It is unfortunate that febrile neutropenia, a decrease of the neutrophil count in the blood accompanying fever, is one of the most common complications that DLBCL patients receiving R-CHOP regimen experience. Given the critical role of neutrophils against bacterial and fungal infections, neutropenia could be deadly. While the association between R-CHOP therapy and neutropenia has been well-established, the negative effect of DLBCL cells on the survival of neutrophils has not been clearly understood. Our previous study have shown that conditioned medium (CM) derived from Ly1 DLBCL cells induces apoptosis in murine neutrophils ex vivo. Additionally, Ly1 CM and doxorubicin synergize to further enhance apoptotic rate in neutrophils, possibly contributing to neutropenia in DLBCL patients.

objectiveWe investigated the mechanism and genes that regulate neutrophil apoptosis induced by secretome of DLBCL cells, which would give insight into the potential role of DLBCL in neutropenia.

methodMurine neutrophils were isolated from bone marrow in C57BL6/J mice using flow cytometry. QuantSeq 3' mRNA-sequencing was conducted on neutrophils following exposure to CM derived from Ly1 DLBCL cells or murine bone marrow cells (control). Quantseq 3'mRNA sequencing data were aligned to identify differentially expressed mRNAs. Next, the expression of genes related to neutrophil apoptosis and proliferation were analyzed and Gene classification and ontology were analyzed.

resultWe identified 1196 (198 upregulated and 998 downregulated) differentially expressed genes (DEGs) in Ly1 DLBCL co-culture group compared to the control group. The functional enrichment analyses of DEGs in co-culture group revealed significant enriched in apoptosis process, and immune system process in gene ontology and the highly enriched pathway of various bacterial infection, leukocyte transendothelial migration, apoptosis, and cell cycle in KEGG pathway. Importantly, Bcl7b, Bnip3, Bmx, Mcl1, and Pim1 were identified as critical regulators of neutrophil apoptosis, which may be potential drug targets for the treatment of neutropenia. We are currently testing the efficacy of the activators/inhibitors of the proteins encoded by these genes to investigate whether they would block DLBCL-induced neutrophil apoptosis.

conclusionIn the present study, bioinformatic analyses of gene expression profiling data revealed the crucial genes involved in neutrophil apoptosis and gave insight into the underlying mechanism. Given our data, it may be likely that novel opportunities for the treatment of neutropenia, and eventually improvement of prognosis of DLBCL patients, might emerge.
