The regulatory network of Chinese medicine-active ingredient-disease-targets showed that cortex mori acted on 163 disease targets of lung cancer mainly by cyclomolorusin, kuwanon D and Moracin A, etc. The core genes involving cortex mori treating lung cancer might consist of JUN, AKT1, etc. The core targets involved 162 biological processes, mainly including nuclear receptor activity, ligand-actived transcription factor activity, etc. The core study targeted 160 pathways, including AGE-RAGE signaling pathways associated with diabetes complications, fluid stress and atherosclerosis. This evidence concerns the gene JUN and lung carcinoma.
