Cancer-fighting agents in broccoli target diseased cells - Yahoo! News via @yahoosg

Scientists say they've found cancer-fighting agents in broccoli and cauliflower that selectively target and kill diseased cells while leaving normal cells healthy. Researchers from Oregon State University were able to demonstrate that a phytochemical found in cruciferous vegetables, sulforaphane, is able to selectively target cancer cells in prostate patients and leave healthy cells alone, unlike traditional chemotherapies. Though sulforaphane has been shown to fight cancer in other studies, lead author Emily Ho says their study was able to confirm that the agent acts as an inhibitor of histone deacetylase, or HDAC, a family of enzymes that play a role in whether certain genes -- like tumor suppressor genes -- are expressed or not. HDAC inhibitors help turn on these silenced genes and restore normal cellular function. Sulforaphane is found at high levels in broccoli, cauli...
