Selection of hub genes in protein–protein interaction (PPI) network. A The interaction diagram of PPI network by 7 hub genes from plasma. B The interaction diagram of PPI network by 22 hub genes from placenta. Network nodes and edges represent genes and gene–gene associations. Blue solid lines represent combination. Purple dotted lines represent the biological process terms corresponding to hub genes
