研究人员日前说,他们证明了人体本身存在一种系统,用以抵抗食品和环境中有毒化学物质的致癌作用。长期以来,科学家一直猜想动物体内存在这种系统,但是,美国约翰斯·霍普金斯大学和日本筑波大学的研究人员说,在研究了20年之后,他们终于利用转基因鼠进行实验,证明了这一点。研究
Researchers said a few days ago that they have proved that there is a system in the human body to combat the carcinogenic effects of toxic chemicals in food and the environment. Scientists have long suspected that such systems exist in animals, but researchers at Johns Hopkins University and the University of Tsukuba in Japan said that after 20 years of research, they finally used transgenic mice to perform experiments. at this point. the study
