Pomegranate juice components block cancer cell migration

 (NaturalNews) One of the most dreaded consequences of cancer is when the disease metastasizes -- meaning it spreads from the primary site where it started to other parts of the body. But University of California, Riverside (UCR) scientists have announced what could be a major breakthrough in halting metastasis. They've discovered components in pomegranate juice that inhibit the movement of cancer cells and weaken the attraction of malignant cells to a chemical signal that has been shown to promote metastasis.

The UCR findings were just presented at the American Society for Cell Biology's 50th Annual Meeting, which is being held in Philadelphia. Specifically, the research team from the UCR laboratory of Manuela Martins-Green, Ph.D., found that pomegranate juice seems to block the spread of prostate cancer cells to the bone. The group is planning additional tests to determine the effects of various doses of the natural pomegranate compounds and whether there are any side effects.  
In earlier studies, Dr. Martins-Green and her colleagues used a standardized concentration of pomegranate juice on two types of laboratory-cultured prostate cancer cells that were resistant to the male hormone testosterone. Scientists have long known that when cancerous cells are resistant to testosterone, that's an indicator those cells have a strong potential to metastasize. Not only did the research team find pomegranate juice killed many cancer tumor cells -- the pomegranate juice treatment also increased cell adhesion and decreased cell migration in those cancer cells that had not died.
