Redox-regulated mechanism may account for zerumbone's ability to suppress cancer-cell proliferation.
A recent report shows that zerumbone (ZER) inhibits the proliferation of, and induces apoptosis in, colon cancer cells. We suggest a mechanism for these phenomena, based on our recently proposed redox model of cell proliferation which stresses the importance of intracellular redox potential E in the control of proliferation of normal and cancer cells.
