From genes to diagnosis: The impact of UNC5B and DOK5 in intracranial aneurysm detection and pathogenesis.
Article in PloS one, 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
objectiveIntracranial aneurysms exhibit a notable prevalence within the general population, characterized by an incidence rate ranging from 1% to 2% and an annual rupture rate of approximately 16.4 per 100,000 individuals.Genes that are diagnostic and therapeutic are being investigated in this study linked to intracranial aneurysms by integrating machine learning, immune infiltration analysis, and single-gene sequencing.
methodsDifferentially expressed genes (DEGs) were identified based on microarray data from the Gene Expression Omnibus (GEO) database between individuals with intracranial aneurysms and healthy controls.The DEGs were functionally analyzed using Gene Ontology (GO),Disease Ontology (DO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways.Diagnostic biomarkers were identified and validated using machine learning algorithms and confirmed with external validation datasets.Subsequently, circulating biomarkers were assessed, and immune cell infiltration analysis along with single-cell sequencing were employed to elucidate the functional roles of the selected diagnostic biomarkers.
resultsIt was found that intracranial aneurysm patients and healthy controls shared 13,101 DEGs, with 1,108 genes upregulated and 969 downregulated.Aneurysms containing intracranial aneurysms showed significant immunoresponse-related enrichment in GO,DO,and KEGG pathway analyses.Technologies based on machine learning, such as LASSO, Random Forest, and SVM-RFE(Support Vector Machine-Recursive Feature Elimination), identified UNC5B and DOK5 as potential diagnostic biomarkers with high efficacy. Immune cell infiltration analysis indicated an elevated presence of various immune cells in intracranial aneurysms, particularly M1 macrophages.The UNC5B gene expression in fibroblasts is linked to intracranial aneurysm pathogenesis.
conclusionIn conclusion, the UNC5B and DOK5 genes emerge as potential diagnostic biomarkers for intracranial aneurysms.There is a positive correlation between UNC5B expression and M1 macrophages and it is primarily found in fibroblasts, suggesting that increased M1 macrophages and UNC5B expression in fibroblasts may contribute to intracranial aneurysm pathogenesis.
