The KEGG pathway enrichment results (Figure 2B) indicated that these genes were involved in multiple pathways, including cancer pathways, corticotropin‐releasing hormone signaling pathway, MAPK signaling pathway, COVID‐19, microRNAs in cancer, PI3K‐Akt signaling pathway, lipid and atherosclerosis, IL‐17 signaling pathway, and TNF signaling pathway. The gene discussed is TNF; the disease is COVID-19.
