As diet is one of the major controllable factors in cancer development, potentially chemopreventive foods are of significant interest to public health. One such food is sorghum (Sorghum bicolor), a cereal grain that contains varying concentrations of polyphenols. In a panel of 15 sorghum germplasm, we identified strains with higher polyphenol content than previously reported for this grain. Bran extracts from the germplasm with the highest and lowest polyphenol content were then tested against HepG2 and Caco2 cancer cells to assess effects on cancer cell viability, reactive oxygen species, apoptosis, DNA damage, cell cycle arrest, and protein expression patterns...
