β-Elemene

β-Elemene is a natural product isolated from Curcuma wenyujin, with an antitumor activity and induce cell apoptosis.β-Elemene significantly inhibited the metastatic capacity of MDR gastric cells in vivo and in vitro. Mechanistically, β-Elemene regulated MMP-2/9 expression and reversed epithelial-mesenchymal transition. β-Elemene upregulated Cbl-b expression, resulting in inhibition of the EGFR-ERK/AKT pathways, which regulate MMP-2/9. β-Elemene upregulated Cbl-b by inhibiting miR-1323 expression. Numbers of metastatic tumor nodules were significantly decreased in the lungs of nude mice after β-Elemene treatment. β-Elemene inhibits the metastasis of MDR gastric cancer cells by modulating the miR-1323/Cbl-b/EGFR signaling axis.
