B3 vitamin component fights carcinogen action in human cells, says research

(Fundação de Amparo Pesquisa do Estado de São Paulo) Brazilian scientists investigate tumoral development caused by benzo[a]pyrene, a hydrocarbon present in cigarette smoke, automotive exhaust, burnt wood fumes and barbecued meat. Culture of human lung cells was exposed to the agent for a week; the preventive role of nicotinamide riboside halted the damaging effects derived from alterations in genetic expression and cell metabolism.
