Researchers at the University of California, Riverside have identified components in pomegranate juice that both inhibit the movement of cancer cells and weaken their attraction to a chemical signal that promotes the metastasis of prostate cancer to the bone. The research could lead to new therapies for preventing cancer metastasis.
The Martins-Green lab applied pomegranate juice on laboratory-cultured prostate cancer cells that were resistant to testosterone (the more resistant a cancer cell is to testosterone, the more prone it is to metastasizing). The researchers – Martins-Green, graduate student Lei Wang and undergraduate students Andre Alcon and Jeffrey Ho – found that the pomegranate juice-treated tumor cells that had not died with the treatment showed increased cell adhesion (meaning fewer cells breaking away) and decreased cell migration.
"We show that pomegranate juice markedly inhibits the function of this protein, and thus this juice has the potential of preventing metastasis of the prostate cancer cells to the bone," Martins-Green said.
A substance found in breast milk can kill cancer cells, reveal studies carried out by researchers at Lund University and the University of Gothenburg, Sweden.. which has given rise to hopes that it can be developed into medication for cancer care in the future. www.sciencedaily.com...
