Researchers studying a group of people with an average age of 97 found they had all inherited a gene that appears to prevent cells ageing.
通过对一组平均年龄为97岁的人的研究，研究人员发现这些长寿者均遗传了一种看似能防止细胞老龄化的基因。
If we can use her DNA to find that mutant gene then we can test it in laboratory animals to see if we can switch if off and slow down the ageing process at will.
如果我们能够在她的DNA当中发现变异的基因，我们可以在其他动物身上试验这些基因，看我们能否任意减缓老化的过程。
The process of ageing is a complex matter in which many different genes appear to be involved, but in time it may become possible to use gene therapy to slow down ageing, if not eliminate it.
衰老过程是一个复杂的事情，涉及到许多不同的基因。但是，人们即使不能消除衰老，最终也能够用基因疗法减缓衰老。
