The pathway over-representation analysis for DEGs, TFs, DC, and DCE was done using ClueGO v2.5.4 (Cytoscape plug-in)105 (https://cytoscape.org/). The annotation of the Ensembl IDs for the respective genes was done using BiomaRt (R package)106,107 from the human Ensembl database, GRCh38.p13. The pathways over-represented in the selected modules were identified by grouping the redundant terms with kappa-score = 0.4. Pathways with a p-value < 0.05 were considered significant. The identified DEGs and TFs were compared with FerrDb—a manually curated resource for regulators and markers of ferroptosis—to identify the common regulators between asthma and ferroptosis.
