Fig. 6From: Inhibitory effect of sodium butyrate on colorectal cancer cells and construction of the related molecular networkProtein-protein interactions network. The interaction between 666 differentially expressed mRNA coding proteins was predicted by using STRING database. The PPI network was constructed based on the protein-protein interactions (PPI) pairs. Red color represents up-regulated proteins, green color represents down-regulated proteins, and gray line represents protein interactionBack to article page
