PPI network analysis of differentially expressed mRNAs and identification of hub mRNAs. A The PPI interaction network of DEGs that differed in PCOS. Each edge links two interacting genes. The size and the color depth of each node correlates positively with its degree of connectivity. B The top 4 significant modules were obtained from the PPI network. C Top 10 GO terms enriched by each modules gene
