摘要: Cell BiologyHealth-conscious consumers may now have another reason for thinking that antioxidants might help protect against cancer. On page [1649][1], researchers report new results suggesting superoxide-—a free radical consisting of an oxygen molecule with extra electron—helps a protein called Ras transmit its growth-stimulating signals to the nucleus. Because overactivity this pathway is thought contribute development wide variety cancers, work provides further support idea reactive species such as superoxide are good targets anticancer drugs.
