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

backgroundUbiquitination, SUMOylation, and neddylation (collectively termed SUN modifications) play crucial roles in cancer pathogenesis and immunotherapy resistance. This study investigated the prognostic significance of these modifications in glioblastoma (GBM).

methodsKey genes associated with SUN modifications and anti-PD-1 resistance were identified using integrated bioinformatic approaches, including differential expression analysis, Weighted Gene Co-expression Network Analysis (WGCNA), and machine learning algorithms. The expression levels of identified genes were subsequently validated in GBM cell lines using RT-qPCR and Western blotting. A prognostic risk model was constructed based on the key genes. Single-cell RNA sequencing (scRNA-seq) and spatial transcriptome analysis were further employed to characterize gene expression patterns.

resultsSix prognostic genes (PLK2, CDC73, PSMC2, SOCS3, ETV4, and LMO7) were identified. CDC73, PSMC2, SOCS3, and ETV4 were upregulated, while PLK2 and LMO7 were downregulated in GBM cells. The six-gene prognostic risk model demonstrated excellent predictive performance, achieving an Area Under the Curve (AUC) exceeding 0.9. The derived risk score exhibited significant correlations with clinical features, immune infiltration levels, and drug sensitivity profiles. Furthermore, scRNA-seq and spatial transcriptome analysis revealed high SOCS3 expression specifically in monocytes and macrophages, suggesting its potential role in mediating the activity of these immune cells to influence tumor progression and drug sensitivity in GBM.

conclusionThis study established a robust six-gene prognostic model related to SUN modifications and anti-PD-1 therapy in GBM. The model demonstrates strong predictive ability and correlates with clinically relevant parameters, highlighting its potential utility for survival prediction and guiding therapeutic management decisions in GBM patients.
