Table 3.

The list of central genes with high centrality values. Top 10% of genes based on degree, betweenness and closeness were considered and the genes that were common in the two centrality list were identified as central elements. K; degree, BC; Betweenness centrality, and CC; Closeness centrality. The asterisked genes are common between three groups of central nodes
