Some vegetables contain chemicals that appear to enhance DNA repair in
cells, which could lead to protection against cancer development, say
Georgetown University Medical Center researchers. In a new study
published in the "British Journal of Cancer" and by the journal
"Nature" the researchers show that in laboratory tests, a compound
called indole-3-carinol (I3C), found in broccoli, cauliflower and
cabbage, and a chemical called genistein, found in soy beans, can
increase the levels of two specific proteins that repair damaged DNA.
This study is one of the first to provide a molecular explanation as to
how eating vegetables could cut the risk of developing cancer, an
association that some population studies have found, says the study's
senior author, Eliot M. Rosen, MD, PhD, professor of oncology, cell
biology, and radiation medicine at Georgetown 's Lombardi Comprehensive
Cancer Center . "It is now clear that the function of crucial cancer
genes can be influenced by compounds in the things we eat," Rosen says.
"Our findings suggest a clear molecular process that would explain the
connection between diet and cancer prevention." In this study, Rosen
exposed breast and prostate cancer cells to increasing doses of I3C and
genistein, and found that these chemicals boosted production of the
repair proteins BRCA1 and BRCA2.
Since decreased amounts of the BRCA proteins are seen in cancer cells,
higher levels might prevent cancer from developing, Rosen speculates,
adding that the ability of I3C and genistein to increase production of
BRCA proteins could explain their protective effects.
The study was funded by the Susan G. Komen Breast Cancer Foundation and
the National Cancer Institute and co-authors include Drs. Saijun Fan,
MD, PhD, Qinghui Meng , MS , Karen Auborn, PhD, and Timothy Carter, PhD.
