Compounds−predicted targets−therapeutic targets interaction networks 1 (a) and 2 (b). Protein targets are represented by their gene names; ▲ represents lupane-type triterpenoids; ♦ represents oleanane-type triterpenoids; represents ursane-type triterpenoids; ● represents the predicted targets of LF triterpenoids; ■ represents the therapeutic targets of breast cancer; represents the targets share by predicted targets and therapeutic targets. The layouts of each type of target nodes are determined by their MCODE score, and the setting is high values to big sizes and dark colors, indicating a more important role in the network
