Networks analysis of the targeted IPF related genes regulated by DLP and DHP were performed as described in our previous study (Lyu et al., 2017 (link), 2018 (link)). The main source of disease targets for IPF was obtained from IPA1 database. According to our previous study (Dong J. et al., 2013), 15 compounds used as marker substances of DLP were uploaded into the IPA system to enable the discovery visualization, including gallic acid, puerarin, daidzin, peoniflorin, naringin, rosmarinic acid, salvianolic acid A, formononetin, calycosin, ethyl gallate, lipoteichoic acid, chlorogenic acid, ferulic acid, cryptotanshinone and tanshinone IIA. Similarly, 14 compound were chosen as major ingredients of DHP for IPA analysis, such as L-proline, L-phenylalanine, caffeic acid, danshensu, rutin, hydroxysafflor yellow A, safflor yellow A, salvianolic acid B, uridine, syringin, chlorogenic acid, ferulic acid, rosmarinic acid, salvianolic acid A (Liu et al., 2013 (link)). “Build-Path Explorer” module was applied to discover IPF-related targets, and the relationship between the targets and DLP or DHP ingredients, respectively.
