Synthetic cocoa chemical slows growth of tumors in human cell lines

d similar to what a person might eat or use," he says.

They found sensitivity to GECGC in both colon cancer cell lines they tested, in cervical cancer cells and in one line of leukemia, tumor cells. Other cell lines were resistant, including ovarian and prostate cancer cells.

Overall, GECGC showed the most effect in treating cancer cells that are normally fast growing, Kim says. And the fact that it demonstrated the most killing power in colon cancer suggests the chemical "could serve as a promising therapeutic for colon cancer," he says. "So far, these data are very convincing."

The researchers do not yet clearly understand the mechanism by which GECGC disrupts tumor growth, but they think it inhibits the physical connections between cancer cells and blocks internal cell signaling pathways.

Kim says that animal studies testing the anticancer power of GECGC are currently underway. "While this work is indeed promising, we have much more study to do before we can say with authority that GECGC has anticancer properties."
