Figure 2From: RETRACTED ARTICLE: Microarray analysis for differentially expressed genes of patients undergoing total knee arthroplasty with ischemia preconditioningProtein-protein interaction network for differentially expressed genes at T1 (a-b). The network includes two small nets a and b. Orange circle means upregulated DEG, and blue circle means downregulated DEG. The line indicates one pair interaction between different proteins.Back to article page
