Finally, in the SVG vs. SG comparison, DEGs were significantly enriched in 14 KEGG pathways, including Ribosome, JAK–STAT signaling pathway, Parkinson disease, Viral protein interaction with cytokine and cytokine receptor, Neuroactive ligand-receptor interaction, PI3K-Akt signaling pathway, Proteasome, Cytokine-cytokine receptor interaction, Virion-Herpesvirus, Cell adhesion molecules, Histidine metabolism, Hypertrophic cardiomyopathy, MAPK signaling pathway, and Glycine, serine, and threonine metabolism (Figure 5E). The gene discussed is SOAT1; the disease is Parkinson disease.
