Fig. 4From: iTRAQ-Based Proteomic Analysis reveals possible target-related proteins and signal networks in human osteoblasts overexpressing FGFR2Protein-protein interaction (PPI) network based on DEPs. The round nodes indicate individual proteins. Regulations of protein abundance are shown as red (up-regulation) or green (down-regulation) circles. DEPs involved in specific pathways are organized in big shadowed circlesBack to article page
