Metascape enrichment analysis showed that overlapping genes are involved in essential functions of the immune system (cytokine signaling, antigen processing and presentation, positive regulation of reactive oxygen species, metabolic processes, platelet degranulation, and response to bacterial and viral infections), respiratory diseases (pertussis, neutrophil degranulation), VEGFA-VEGFR2 signaling pathway, cell regulation, and death (apoptotic signaling pathway, I-kappaB kinase/NF-kappaB signaling) (Table 3, Supplemental File 3). Here, KDR is linked to viral infectious disease.
