Colorectal cancer cases continue
to grow among men and women in the US, largely fueled by a diet of processed
convenience foods and a sedentary lifestyle void of regular exercise. Colorectal cancer is the
second most common cause of cancer death in the United States, with more than
100,000 new diagnoses and 52,000 deaths attributed to the disease each year. Natural
compounds including curcumin and resveratrol have proven effective in the
prevention of colon cancer, and now scientists have determined that grape
seed extract (GSE) specifically targets damaged cells in the digestive
tract to provide an effective treatment for colorectal cancer.
Grape Seed Extract Promotes Programmed Cancer Cell Death to Prevent Colon
Cancer Progression
A research team from the University of Colorado Cancer Center have published the results of
a study in the journal, Cancer Letters demonstrating that the more advanced colorectal
cancer cells are, the more GSE inhibits their growth and survival. Conversely,
GSE does not affect healthy cells and is shown to specifically target only
cancerous cells. The authors note that this is an important finding in light of
the increased number of late stage colon cancer cases currently being
diagnosed.
Lead study author and doctoral
candidate Molly Derry commented “We've known for quite a while that the bioactive
compounds in grape seed extract selectively target many types of cancer cells.
This study shows that many of the same mutations that allow colorectal cancer
cells to metastasize and survive traditional therapies make them especially
sensitive to treatment with GSE.” This research could provide a critical
starting point to encourage the use of natural therapies to treat colon cancer,
rather than the traditional slash, burn and poison methods that cause more harm
than good for many who suffer from the disease.
Supplement
with Grape Seed Extract to Reduce Cellular Oxidation Associated with Cancer
Proliferation
Scientists studied the effect of GSE on
various stages of colon cancer cell lines, ranging from Stage 1 to Stage IV.
They found that similar concentrations of GSE exerted a more profound effect in
eradicating more advanced stages of colon cancer, indicating that the natural
compound may provide an effective treatment option for more advanced forms of
the disease. The Ms. Derry noted “It required less than half
the concentration of GSE to suppress cell growth and kill 50 percent of stage
IV cells than it did to achieve similar results in the stage II cells.”
The study team discovered that GSE targets
colorectal cancer through inducing oxidative stress that leads to the
programmed cell death known as apoptosis. Ms. Derry concluded “the many bioactive compounds of GSE are able to target
multiple mutations. The more mutations a cancer presents, the more effective
GSE is in targeting them.” Nutrition experts recommend supplementing with a
standardized whole grape seed extract (150 to 250 mg) daily to provide a
protective shield against colon and digestive cancers.
