纪录片《长生不老》 20停止衰老

Ten years ago Bill was part of the team that identified

10年前一个小组找到了对付端粒变短的物质

a natural antidote¹ to telomere shortening that's in our bodies.

比尔也是那个研究小组的一员

It's an enzyme² called telomerase.

它是一种酶 叫端粒酶

It looked like he'd found

看起来他已经找到了

the cause and a potential solution to ageing.

衰老的原因以及可能的抵抗方法

It had been believed for a long time

我曾经深信不疑地认为

that we aged³ because of telomere-shortening

衰老是由于端粒变短造成的

but there was no way to prove

但除非我们能

that unless we could stop the telomere-shortening,

阻止端粒变短 不然就无法求证

and we did this by discovering the enzyme telomores

发现端粒酶能阻止端粒变短

and putting it inside of cells and showing that in that

把端粒酶放入细胞 在此情况下

case the telomeres quit shortening and they stopped ageing.

端粒停止变短 衰老也因此停止

The cells that naturally produce

产生端粒酶的细胞

telomerase are our reproductive cells, and they never age.

是我们的生殖细胞 它们从不变老

But the body needs more of this enzyme.

不过身体需要更多这种酶

We want to find a drug that will get

我们想要找到一种药

inside of our cells and turn that telomores gene⁴ on

能进入细胞内 开启制造端粒酶的基因

so all the rest of our cells in our body don't age,

让其余所有细胞都如生殖细胞一样

just like our reproductive cells don't age.

不会衰老
