Fig. 2From: Microarray analysis identification of key pathways and interaction network of differential gene expressions during osteogenic differentiationProtein-protein interaction (PPI) network (STRING). a FRZB. b 14 genes involved in the PI3K/AKT pathway. The red nodes indicated upregulation DEGs, and the green nodes indicated downregulation DEGs. c Presence of β-catenin in the protein-protein interaction (PPI) network.
