According to a new University of Illinois at Chicago study’s news release, published November 2, 2010, “Black raspberries may prevent colon cancer, study finds,” Black raspberries are highly effective in preventing colorectal tumors in two mouse models of the disease. UIC’s department of pathology and the National Cancer Institute funded the study.
Other berries, such as blueberries and strawberries, are also known to have cancer-preventing effects, but their effects are not as great as those of black raspberries. Also see the November 2, 2010 Live Science article on black raspberries and possible colon cancer prevention.
If you want to grow blackberries in Sacramento, check out the website, How to farm blueberries, blackberries in Central Valley for future events. Also see the UC Davis article, Growing Cane Berries in the Sacramento Region. But you’ll have to wait for the season because black raspberries bear fruit in June, after which the fruited canes are cut. You could buy frozen black raspberries at most any supermarket in Sacramento.
The findings are published in the November issue of Cancer Prevention Research. Check out the study, “Black Raspberries Inhibit Intestinal Tumorigenesis,” in Apc1638 /− and Muc2−/− Mouse Models of Colorectal Cancer. Cancer Prev Res, 1940-6207-CAPR-10-0124 DOI: 10.1158/1940-6207.CAPR-10-0124. Authors are Xiuli Bi, Wenfeng Fang, Li-Shu Wang, Gary D. Stoner and Wancai Yang.

How black raspberries may help prevent colorectal cancer, according to research from the National Cancer Institute
Colorectal cancer is the third most common cancer and the second leading cause of cancer-related death in both men and women in the U.S., according to the National Cancer Institute. Building on previous research that found black raspberries have antioxidant, anti-cancer, anti-neurodegenerative and anti-inflammatory properties, the researchers looked at the fruit’s ability to prevent colon cancer.
“We saw the black raspberry as a natural product, very powerful, and easy to access,” Dr. Wancai Yang, explained, according to the news release, “Black raspberries may prevent colon cancer, study finds.” Dr. Yang is an assistant professor of pathology at the UIC College of Medicine and senior author of the study, whose research focuses on the interactions of genetic and nutritional factors in the development of intestinal cancer and tumor prevention.
The researchers used two strains of mice, Apc1638 and Muc2, which each have a specific gene knocked out, causing the mice to develop either intestinal tumors (in the case of Apc1638) or colitis in the case of Muc2. Colitis is an inflammation of the large intestine that can contribute to the development of colorectal cancer.
Both mouse strains were randomized to be fed either a Western-style, high-risk diet (high in fat and low in calcium and vitamin D) or the same diet supplemented with 10 percent freeze-dried black raspberry powder for 12 weeks. The researchers found that in both mouse strains the black raspberry-supplemented diet produced a broad range of protective effects in the intestine, colon and rectum and inhibited tumor formation.
In the Apc1638 mice, tumor incidence was reduced by 45 percent and the number of tumors by 60 percent. The researchers found that black raspberries inhibited tumor development by suppressing a protein, known as beta-catenin, which binds to the APC gene.
In the Muc2 mice, tumor incidence and the number of tumors were both reduced by 50 percent, and black raspberries inhibited tumor development by reducing chronic inflammation associated with colitis. The researchers now hope to obtain funding to begin clinical trials in humans, said Yang. Because black raspberries not only prevent cancer but also inflammation, they may also protect against other diseases, such as heart disease.
Yang is a member of the UIC Cancer Center. Co-authors are Xiuli Bi of UIC, Wenfeng Fang of UIC and Wuhan University in China, and Li-Shu Wang and Gary Stoner of the Ohio State University. UIC ranks among the nation’s leading research universities and is Chicago’s largest university with 27,000 students, 12,000 faculty and staff, 15 colleges and the state’s major public medical center.
A hallmark of the campus is the Great Cities Commitment, through which UIC faculty, students and staff engage with community, corporate, foundation and government partners in hundreds of programs to improve the quality of life in metropolitan areas around the world.
