Relationship between DEGs. a Protein-protein interaction (PPI) network, the more the number of connections, the larger of the protein. The orange was defined as dark color to map parameters, which represented the high value of protein. The yellow was defined as middle color to map parameters, which presented the middle value of protein. The blue was defined as bright color to map parameters, which represented the low value of protein. The small sizes showed the low values, and the large sizes represented the high values. b The common hub genes identified from different algorithm. c The common hub genes of protein-protein interaction network. d Heat maps of the common hub genes
