Fig. 4From: Identification of key regulators responsible for dysregulated networks in osteoarthritis by large-scale expression analysisProtein–protein interaction network of DEGs. a STRING was used to evaluate protein interaction of DEGs between OA and normal. The interaction was visualized by Cytoscape. b Top 10 hub genes ranked by betweenness. cytoHubba was used to extract the hub genes in the networkBack to article page
