Pan-cancer multi-omics analysis identifies SYNGR4 as a novel clinical prognostic biomarker and therapeutic target in lung adenocarcinoma.
Article in Discover oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundWhile the synaptic vesicle protein SYNGR4 has established roles in the pathobiology of motor neuron disease, its comprehensive oncogenic significance across diverse cancers, and its specific value as a clinical biomarker and therapeutic target in lung adenocarcinoma (LUAD), are entirely unexplored.
methodsOur pan-cancer multi-omics analysis systematically assessed the expression, prognostic value, prognostic nomogram models, and clinical correlates of SYNGR4, investigated its DNA methylation, genetic alterations, and functional pathways (GO/KEGG/GSEA), and evaluated its associations with immune infiltration, immunotherapy response, and drug sensitivity across various cancer types. In addition, we performed qPCR, CCK-8, colony formation, EdU staining, and wound-healing analyses to elucidate the role of SYNGR4 in LUAD proliferation and migration.
resultsOur pan-cancer multi-omics results indicate that SYNGR4 is upregulated in multiple cancers and correlates with prognosis. Its expression was linked to DNA methylation, immune cell infiltration and improved responses to PD-1 blockade (nivolumab) and anti-PD-L1 therapy. SYNGR4 expression also showed positive correlations with sensitivity to MEK inhibitors (PD-0325901, Trametinib) and Docetaxel. Pathway analysis linked SYNGR4 to cell cycle progression and synthesis of DNA. In addition, knockdown of SYNGR4 via siRNA suppressed the proliferative and migratory capacities of LUAD cells in vitro.
conclusionThis study establishes SYNGR4 as a novel prognostic biomarker in LUAD, thereby positioning it as a potential therapeutic target with clinical utility.
