Identification of a hypoxia-related gene signature associated with childhood asthma.
Article in Genes & genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundHypoxia is a significant manifestation of severe asthma in children. An early and accurate diagnosis is crucial for enhancing treatment outcomes and mitigating long-term complications. This study aims to utilize bioinformatics analysis to investigate hypoxia-related genes (HRGs) in childhood asthma.
objectiveThis study aims to develop a diagnostic model and identify key hypoxia-related biomarkers in childhood asthma based on transcriptomic data analysis.
methodsHypoxia-related differentially expressed genes (HRDEGs) were identified from bronchial epithelial transcriptomes (GSE27011/GSE40732 datasets) using limma analysis. A diagnostic model was developed using LASSO regression, and hub genes were identified via protein-protein interaction (PPI) networks. Asthma subtyping and immune microenvironment characterization were conducted using ConsensusClusterPlus and CIBERSORTx, respectively. Experimental validation in house dust mite (HDM)-induced asthmatic mice confirmed transcriptional changes in candidate genes.
resultsWe obtained 19 HRDEGs and 11 model genes (AHR, AKR1C3, ELP3, GNAL, GZMB, LPP, MAFG, PDGFD, PPP1R12B, SYNE2, and TAF15). Regression analyses demonstrated the model's robust diagnostic performance. PPI analysis identified 10 hub genes associated with asthma, with AKR1C3 showing high diagnostic accuracy for different molecular subtypes. Immune infiltration analysis indicated significant correlations between hub genes and eight immune cell types, including B cells, effector T cells, cytotoxic T cells, regulatory T cells (Tregs), monocytes, mast cells, eosinophils, and neutrophils.
conclusionsIn this study, a hypoxia-related gene signature associated with childhood asthma was identified. These findings not only highlight potential therapeutic targets for asthma but also offer new insights into its pathogenesis.
