Bethesda, MD—The next cancer drug might come straight from
the grocery store, according to new research published in the November
2007 issue of
The FASEB
Journal. In the study, French scientists describe how high
and low doses of polyphenols have different effects. Most notably, they
found that very high doses of antioxidant polyphenols shut down and
prevent cancerous tumors by cutting off the formation of new blood
vessels needed for tumor growth. Polyphenols are commonly found in red
wine, fruits, vegetables, and green tea.
At relatively low doses, the French researchers found that the same
polyphenols play a beneficial role for those with diseased hearts and
circulatory systems by facilitating blood vessel growth. The amount of
polyphenols necessary for this effect was found to be the equivalent of
only one glass of red wine per day or simply sticking to a healthy diet
of fruits and vegetables containing polyphenols. This diet is known as
the “Mediterranean Diet.” This study also adds to a
growing body of research showing dose-dependent relationships for many
types of commonly used compounds. For instance, research published in
the October 2006 issue of
The
FASEB Journal shows that aspirin, through different
mechanisms, also has a dose-dependent relationship for heart disease
and cancer.
"When it comes to finding treatments for complex diseases, the answers
are sometimes right there waiting to be discovered in unexpected places
like the produce aisles and wine racks of the nearest store,”
said Gerald Weissmann, M.D., Editor-in-Chief of
The FASEB Journal.
“But it takes modern science to isolate the pure compound,
test it in the lab, and to go on from there to find new agents to fight
disease.”
According to the authors, the amount of polyphenols necessary to obtain
an anti-cancer effect is the equivalent of drinking about a bottle of
red wine each day. This amount of daily alcohol consumption obviously
is unhealthy, but the research suggests that polyphenols extracted from
plants or red wine could be converted into a pill that is highly likely
to be safe. Such a pill also would be relatively easy and inexpensive
to create and deliver.
“The use of plant polyphenols as therapeutic tools presents
important advantages,” said Daniel Henrion, senior author of
the study, “because they have a good safety profile, a low
cost and they can be obtained everywhere on the planet.”
The FASEB Journal
(

is published by the Federation of American Societies for Experimental
Biology (FASEB) and is consistently ranked among the top three biology
journals worldwide by the Institute for Scientific Information. FASEB
comprises 21 nonprofit societies with more than 80,000 members, making
it the largest coalition of biomedical research associations in the
United States. FASEB advances biological science through collaborative
advocacy for research policies that promote scientific progress and
education and lead to improvements inhuman health.
