PPI network construction and key genes screening. A Diagram of protein-protein interaction network. Each dot represented a node. The more line segments connected to the node, the greater the degree of this node. The degree of node was reflected by its size and color. The larger the node, the deeper color from yellow to red, the greater the degree. B Network diagram of the top 10 genes screened according to degree. The darker color from yellow to red represented greater degree. C The network diagram of the top 10 genes screened via MCC algorithm. The darker color from yellow to red represented greater score
