Can Pomegranate Juice Prevent Metastasis?

University of California researchers reported that prostate cancer cells subjected to pomegranate juice did not metastasize as readily as untreated prostate cancer cells. Manuela Martins-Green led the in vivo study, which was presented at the 50th annual meeting of the American Society for Cell Biology. Martins-Green said the fruit contains chemicals that appear to inhibit a protein in bone marrow that helps facilitate cancer metastasis. She speculated that this might open the door to new drugs based on these chemicals, which could have applications for other solid tumors.
