This research, which was published in the journal Clinical Epigenetics, primarily studied the effect on prostate cancer cells. But the same processes are probably relevant to many other cancers as well, researchers said, including colon and breast cancer. Sulforaphane was identified years ago as one of the most critical compounds that provide much of the health benefits in cruciferous vegetables, and scientists also knew that a mechanism involved was histone deacetylases, or HDACs. This family of enzymes can interfere with the normal function of genes that suppress tumors.
