Figure 8. Functional enrichment analyses of COPS subunit genes and neighboring genes in HCC (from STRING and DAVID). (A) Associations among COPS complex components in HCC revealed by Spearman correlation analysis. (B) Biological interaction network of COPS subunit genes and neighboring genes. (C) GO and KEGG enrichment analysis showing biological processes, cellular components, molecular functions, and molecular pathways of COPS subunits and neighboring network genes.
