The enriched KEGG pathways of quercetin, kaempferol, rhamnocitrin, tetramethoxyluteolin, and norartocarpetin were similar and they were all related to ABC transporters, bile secretion, prostate cancer, and antifolate resistance; quercetin, kaempferol, rhamnocitrin, and tetramethoxyluteolin were all related to the HIF-1 signaling pathway and renal cell carcinoma; quercetin, rhamnocitrin, tetramethoxyluteolin, and norartocarpetin were all related to the serotonergic synapse. The gene discussed is ABCG2; the disease is prostate cancer.
