美国多个科研机构的科学家说,他们通过对实验鼠的研究证明,在细胞内增加抗氧化酶的生成会显著延长动物寿命、减少与衰老相关的疾病。这一成果也进一步支持了自由基引起衰老的理论。由美国华盛顿大学医学院、加利福尼亚大学欧文分校、得克萨斯大学某专家说,他们通过转基因方法,在实验鼠体内植入人类的过氧化氢酶基因,分别使细胞内的细胞质、细胞核以及线粒体中的过氧化氢酶含量显著提高。 Scientists from a number of scientific institutions in the United States say that their studies on laboratory mice have shown that increasing the production of antioxidant enzymes in cells can significantly prolong animal life and reduce aging-related diseases. This result further supports the theory that free radicals cause aging. According to an expert from the University of Washington School of Medicine, the University of California, Irvine, and the University of Texas, they implanted the human catalase gene in laboratory mice through genetic modification methods, respectively, in the cytoplasm, nucleus and mitochondria of cells. Oxygenase content increased significantly.
