Statin plus cancer drug deliver combo punch to brain cancer cells

... statin already is being studied in people at high risk for the deadly skin cancer, melanoma. First extracted from corn lilies in the 1950s, cyclopamine is a powerful toxin known to stunt fetal development and cause birth defects in humans and animals. Its connection to anti-cancer efforts grew out of ...
