HIF1A and human papilloma virus infection: KEGG enrichment analysis revealed that infection-related signaling pathways, inflammation-related signaling pathways, apoptosis signaling pathways, and oxidative stress-related signaling pathways were significantly enriched in diabetes-related complications, like human papillomavirus infection, hepatitis, Kaposi sarcoma-associated herpesvirus infection, TNF-signaling pathway, HIF-1 signaling pathway, and AGE-RAGE signaling pathway (Figure 3(b)).
