A plant chemical isolated from fresh blackberries may inhibit tumor growth.
Fresh blackberries contain a compound that may interfere with genes associated with cancer-promoting agents. The purified compound, cyanidin-3-glucoside (C3G), inhibited growth and spread of skin and lung tumors in tests with laboratory mice (Journal of Biological Chemistry, volume 281, pages 17359 to 17368).
The number and size of skin tumors were significantly reduced among mice that had been supplemented with C3G, when compared to those that had not, the scientists found. In another study, the growth of lung tumors and spread of the cancer to other organs were significantly reduced in immune-system-suppressed mice fed the C3G compound.
Scientists with ARS at Beltsville, Md., and the National Institute for Occupational Safety and Health, Morgantown, W.Va., collaborated in the research.
