Whole tomato extract may help prevent and treat gastric cancer
Researchers from the United States and Italy have found that full extracts from two tomato varieties,San Marzano and Corbarino,block the growth of gastric cancer cells and inhibit their malignant features.The study's co-author,professor Antonio Giordano,director of the Sbarro institute of molecular medicine at temple university in Philadelphia,and colleagues published their findings in the journal of cell physiology.
Previous studies have shown that compounds found in tomatoes,such as lycopene,a carotenoid that makes tomatoes red,may help fight cancer.However,the researchers noted that few studies had been done on the overall cancer-fighting effects of tomatoes,and they set about tackling the research gap.
The researchers examined the effects of San Marzano and Corbarino on gastric cancer cell lines.They found that each extract not only blocks the growth of gastric cancer cells,but also interferes with the metastasis of cancer cells.
In addition,the researchers found that the anti-cancer effect of the whole tomato extract was not specific to a specific compound.Their antineoplastic effects do not appear to be linked to specific components(such as lycopene),suggesting that the anti-cancer effects of tomatoes are generally effective.
The results of this study suggest that whole tomato extract may help prevent and treat gastric cancer.
