Fig. 1From: iTRAQ-based proteomic profiling reveals different protein expression between normal skin and hypertrophic scar tissueEstablishment of protein-protein interaction networks for scar/skin tissue differential proteins. The protein-protein interaction networks were constructed by cytoscape software according the HPRD. Proteins are represented with grey nodes, and interactions are represented with edges. a Scar significantly up-regulated PPI network was constructed, 20 of 41 scar-up-regulated proteins were included in the network. b Scar significantly down-regulated PPI network was constructed, 27 of 48 scar-up-regulated proteins were included in the networkBack to article page
