KEGG pathway analysis also revealed the top ten relevant pathways, including the FoxO signalling pathway, adipocytokine signalling pathway, AMPK signalling pathway, fluid shear stress and atherosclerosis, longevity regulating pathway, IL-17 signalling pathway, prostate cancer, nonalcoholic fatty liver disease, coronavirus disease-COVID-19, and longevity regulating pathway-multiple species (Fig. 2I). Here, IL17A is linked to COVID-19.
