The gene regulatory network in HCC. Different colors represent nodes in different network modules. Size of nodes is proportional to the out-degree of nodes. Black edges represent regulations in the core GRN, and the width of the edges in the core GRN are proportional to the edge-betweenness values calculated from the global GRN.
