Fig. 5From: Identification and validation of hub genes of synovial tissue for patients with osteoarthritis and rheumatoid arthritisHub genes of OA-specific and RA-specific PPI networks. A OA relative PPI network. B RA relative PPI network. C PPI network constructed by DEGs between OA and RA. D Three groups of top 20 connections in PPI network. The red and blue rectangles represent the proteins encoded by up or down-regulated DEGs, respectively. The larger rectangles indicate the higher degree in networksBack to article page
