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

backgroundThe discovery of glioblastoma (GBM)-initiating cells (GICs) has impacted GBM research. These cells are not only tumorigenic but also exhibit resistance to radiotherapy and chemotherapy. Therefore, it is crucial to characterize GICs thoroughly and identify new therapeutic targets. In a previous study, we successfully identified epithelial-V-like antigen 1 (EVA1) as a novel functional factor specific to GICs.

methodsHybridoma cells were generated by immunizing BALB/c mice with EVA1-Fc fusion protein. The reactivity of the supernatant from these hybridoma cells was examined using EVA1-overexpressing cells and GICs. Candidate antibodies were further selected using Biacore surface plasmon resonance analysis and 2 cytotoxicity assays-antibody-dependent cell cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Among the antibodies, the cytotoxicity of the B2E5-antibody drug conjugate (B2E5-ADC) was evaluated by both adding it to cultured GICs and injecting it into GIC tumor-bearing brains.

resultsB2E5 demonstrated a high affinity for human EVA1 and effectively killed both EVA1-expressing cell lines and GICs in culture through ADCC and CDC. B2E5-ADC also exhibited strong cytotoxicity to GICs in culture and prevented their tumorigenesis in the brain when administered intracranially to the tumor-bearing brain.

conclusionOur data indicate that B2E5-ADC is a new and promising therapeutic strategy for GBM.
