Expression of core genes and subnetwork of core genes. a Heatmap of core genes in EGFR-TKI resistance and sensitive groups. b boxplot of each core gene between two groups. c Subnetwork of compounds and targets. The triangles represent different compounds and different color represent herbs that include the compounds. d The compound-pathway interaction network is constructed by compound and the pathway that consisted of core targets. Red lines represent compounds directly related to drug resistance
