CDK2 was significantly enriched in multiple immune- and virus-related pathways, including the Rap1 signaling pathway, regulation of actin cytoskeleton, RIG-I-like receptor signaling, NOD-like receptor signaling, influenza A, and hepatitis C. To visualize the distribution of significantly enriched pathways, the top five upregulated and downregulated gene sets were selected based on their enrichment scores. This evidence concerns the gene CDK2 and hepatitis C virus infection.
