Abstract EN
Goniothalamin (GTN), a styryl-lactone, exhibits inhibitory effects on many kinds of cancer cells in vitro.
The objectives of this study were to investigate the anticancer activities of GTN and molecular signaling pathways associated with cell death in human breast cancer MDA-MB-231 cell line.
GTN inhibited the growth of MDA-MB-231 cells.
Apoptosis was confirmed by annexin V-FITC and PI staining, and apoptotic morphology was observed by microscopy.
Reduction of mitochondrial transmembrane potential and enhanced caspases activities were found in GTN-treated MDA-MB-231 cells.
GTN significantly altered apoptosis-related protein expressions, including Noxa, PUMA, Bax, Bim, Bad, Bcl-2, Bcl-xL, and DIABLO, which was related to the gene expression levels.
Mitochondrial calcium released to the cytosol and ER stress related proteins increased, which correlated with increases in ER stress gene expression levels.
GTN induced hydrogen peroxide and superoxide anion radicals in MDA-MB-231 cells associated with cell cycle arrest in G2/M phase, which was induced by phosphorylation and ATM gene expression.
Moreover, GTN had synergistic effects when combined with cyclophosphamide, 5-fluorouracil, paclitaxel, and vinblastine, and additive effect with methotrexate through caspases enzyme-acceleration.
In conclusion, goniothalamin-induced MDA-MB-231 cell apoptosis occurred via intrinsic and extrinsic pathways, along with ER stress.
These pathways provide new targeted drug strategies for advancements in anticancer medicine.
