Gene 'knockout' floors tobacco carcinogen

Researchers at NC State University have developed a method to silence a gene that turns nicotine into a carcinogen, resulting in a six-fold decrease in N-nitrosonornicotine and a 50% overall reduction in TSNAs. This breakthrough could lead to tobacco products with reduced amounts of cancer-causing agents.
