Prostate cancer is the most common form of cancer in men, and most cases develop in men aged 65 or older. It is a challenging cancer to treat because, unlike many other cancers, prostate cancer usually progresses very slowly. It can take up to 15 years for the cancer to spread from the prostate to other parts of the body (metastasis), typically the bones. Once it has spread to the bones, it cannot be cured, and treatment is focused on prolonging life and relieving symptoms.
The team hope that the fruit will have a similar effect on other cancers.
Researchers 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).
They 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.
Next, the researchers identified the following active groups of ingredients in pomegranate juice that had a molecular impact on cell adhesion and migration in metastatic prostate cancer cells: phenylpropanoids, hydrobenzoic acids, flavones and conjugated fatty acids.
"Having identified them, we can now modify cancer-inhibiting components in pomegranate juice to improve their functions and make them more effective in preventing prostate cancer metastasis, leading to more effective drug therapies," One of the researchers said.
"Because the genes and proteins involved in the movement of prostate cancer cells are essentially the same as those involved in the movement of other types of cancer cells, the same modified components of the juice could have a much broader impact in cancer treatment."
The research was presented on Dec. 12, 2010 at the 50th annual meeting of the American Society for Cell Biology in Philadelphia.
The pomegranate is a wonderful all-round health protector. The noble scholar Ibn al-Qayyim said in his Prophetic medicine that the pomegranate provides "slight but excellent nourishment," and has benefits for the stomach, throat, chest and lungs. pomegranate juice contains three times the amount of polyphenols than are found in green tea. Pomegranates are also rich in vitamins B and C, and many other antioxidants that make it a powerful superfood.
