Investigating the Mechanisms of Action of Depside Salt from Salvia miltiorrhiza Using Bioinformatic Analysis

Figure 2

The protein-protein interaction (PPI) network constructed for the depside salt from Salvia miltiorrhiza-associated genes. Green squares, purple circles, and brown triangles represent magnesium lithospermate B-associated genes, rosmarinic acid-associated genes, and lithospermic acid-associated genes, respectively. Red diamonds represent genes associated with more than one drug. The larger nodes indicate genes with higher degrees. The degree indicates the number of interactions with other proteins in the PPI network.
