A PPI network and three significant modules of DEGs. (A) A PPI network of DEGs created by STRING. Circles represent genes, and lines represent PPIs. (B) The most significant module identified by MCODE (score =4). (C) The second most significant module identified by MCODE (score =3.5). (D) The third most significant module identified by MCODE (score =3.429). PPI, protein-protein interaction; DEGs, differentially expressed genes; STRING, Search Tool for the Retrieval of Interacting Genes/Proteins; MCODE, molecular complex detection.
