Fig. 2From: Integrating transcriptome-wide association study and mRNA expression profile identified candidate genes related to hand osteoarthritisImage showing protein-association networks of identified genes (a IRS2, b SKP2, c CRIM1, d DHRS3) for osteoarthritis. The image was generated using the STRING online tool (https://www.string-db.org/). The enriched function which is associated with the mechanism of osteoarthritis has been selected during the analysis, and the corresponding proteins nodes in the network are automatically highlighted in colorBack to article page
