这篇讲什么
研究人员首次对世界最长寿陆地动物、约194岁的阿尔达布拉巨龟乔纳森进行基因组测序,发现其线粒体功能相关基因的效率与5岁同类相当。高效线粒体或为DNA修复系统提供更多能量,从而延缓衰老。研究还发现,他的一些基因变化与超级百岁老人相似。
原文开头
THE world’s oldest known land animal, Jonathan the giant tortoise, has had his genome probed for the first time. This has revealed that parts of his genome to do with mitochondrial function are as efficient as those of a 5-year-old member of his species. Efficient mitochondria may give his DNA repair systems more energy to fight off the effects of ageing, enabling him to live to an estimated age of 194. What’s more, some of his genetic changes seem similar to those of supercentenarians. …
