ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE: Zanthoxylum bungeanum Maxim. (ZBM), a Chinese herb medicine and food additive, has been shown to have broad-spectrum beneficial effects. However, the anticancer activities of its seed have not been reported. AIM OF THE STUDY: for the first time investigated the anti-proliferation activity of seed oil of ZBM (ZBSO) on melanoma A375 cells as well as the underlying mechanisms. MATERIALS AND METHODS: The chemical composition of ZBSO was analyzed by Ultra Performance Liquid Chromatography. A375 cells exposure at different concentrations of ZBSO to examine the selectivity versus normal skin cells, invasion, apoptosis and cell cycle arrest. Furthermore, transcriptome analysis was employed to investigate potential anticancer mechanisms of ZBSO. RESULTS: Major compounds of ZBSO were identified and unsaturated fatty acid made up the major compound. ZBSO-treated A375 cells showed more typical apoptotic morphologic features than normal cells. ZBSO can significantly inhibit invasion and proliferation of A375 cells by G1 phase arrest and induction of apoptosis. Transcriptome analysis showed that ZBSO may affect cell cycle and MAPK signaling pathway of A375 cells. CONCLUSION: ZBSO possessed anticancer activities that were selectively effective to A375 cells. This study support the hypothesis that ZBSO is a capable candidate for anti-melanoma agent, and provide new insights for future work on investigating the utilization of ZBSO in malignant melanoma treatment.
