Veggies Stopping Cancer
An anti-cancer compound found in broccoli and cabbage works by blocking a key enzyme associated with rapidly advancing cancer.
The compound found in the veggies, indole-3-carbinol, is already in human clinical trials because of its ability to stop breast and prostate cancer growth in mice. The new findings are the first to explain how indole-3-carbinol stops cell growth.
These new findings could lead to the development of an improved version of the chemical that could be used as a drug to work against breast and prostate cancer tumors.
"Humans have co-evolved with cruciferous vegetables like broccoli and Brussels sprouts, so this natural source had a lot fewer side effects," study coauthor Gary Firestone, UC Berkley professor of molecular and cell biology, was quoted as saying.
Indole-3-carbinol is only one of many plant-derived chemicals that Firestone is investigating in his laboratory as potential anti-cancer agents.
