In total, 21 signaling pathways were enriched in differentially expressed genes, and the top five enriched pathways were the PI3K-Akt signaling pathway (p = 0.03), coronavirus disease (COVID-19) (p = 0.006), MAPK signaling pathway (p = 0.026), human papillomavirus infection (p = 0.049), and IL-17 signaling pathway (p = 3.93 × 10−4). Here, IL17A is linked to human papilloma virus infection.
