An enrichment analysis of 146 DEGs was conducted to gain insight into the biological function of STEAP4. The KEGG analysis revealed that the DEGs primarily regulated the interleukin (IL)-17 signaling pathway, steroid hormone biosynthesis, cytokine-cytokine receptor interaction, Fc epsilon RI signaling pathway and ferroptosis, all of which are closely related to asthma (Figure 6D). This evidence concerns the gene STEAP4 and asthma.
