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

objectiveEpstein-Barr virus (EBV) is a well-recognized oncogenic virus that can induce host cell metabolic reprogramming and tumorigenesis by targeting vital metabolic enzymes or regulators. This study aims to explore the role of wild-type isocitrate dehydrogenase 2 (IDH2) in metabolic reprogramming and tumorigenesis induced by EBV-encoded latent membrane protein 1 (LMP1).

methodsMechanistic dissection of wild-type IDH2 in EBV-LMP1-induced tumorigenesis was investigated using western blotting, real-time polymerase chain reaction (PCR), immunochemistry, chromatin immunoprecipitation (ChIP), and luciferase assay. The role of wild-type IDH2 was examined by cell viability assays/Sytox Green staining in vitro and xenograft assays in vivo.

resultsIDH2 over-expression is a prognostic indicator of poorer disease-free survival for patients with head and neck squamous cell carcinoma (HNSCC). IDH2 expression is also upregulated in nasopharyngeal carcinoma (NPC, a subtype of HNSCC) tissues, which is positively correlated with EBV-LMP1 expression. EBV-LMP1 contributes to NPC cell viability and xenograft tumor growth mediated through wild-type IDH2. IDH2-dependent changes in intracellular α-ketoglutarate (α-KG) and 2-hydroxyglutarate (2-HG) contribute to EBV-LMP1-induced tumorigenesis in vitro and in vivo. Elevated serum 2-HG level is associated with high EBV DNA and viral capsid antigen-immunoglobulin A (VCA-IgA) levels in patients with NPC. A significantly positive correlation exists between serum 2-HG level and regional lymph node metastases of NPC. EBV-LMP1 enhances the binding of c-Myc with the IDH2 promoter and transcriptionally activates wild-type IDH2 through c-Myc. Targeting IDH2 decreased intracellular 2-HG levels and survival of EBV-LMP1-positive tumor cells in vitro and in vivo.

conclusionsOur results demonstrate that the EBV-LMP1/c-Myc/IDH2
