Centrality analysis of the HCC-related PPI network. (a) Density distribution of centrality parameters (degree centrality, betweenness centrality, and closeness centrality) as calculated by the Cytoscape plugin Network Analyzer and R language. (b) Correlations among centrality parameters, as analyzed by R. (c) 10 core molecules with high degree, betweenness, and closeness centralities were selected by Venny 2.1 (top 20% of each set of centrality parameters). The first-ranked module contained 10 core molecules discovered by centrality analysis.
