So in that case, you still get some normal expression of the gene from the endogenous genome, but now you have a transgene that's inserted there.

在这种情况下， 你从内源基组中获得该基的一些正常表达，但现在你有了一个插入到那里的转基。

Researchers learned to control the expression of transgenes, and were soon racing—in both academic and industrial contexts—to create organisms capable of expressing human genes for the production of human hormones.

研究人员学会了控转基的表达，并且很快在学术和工业领域竞相创造出够表达人类基的生物体的激素。

So we're talking about it when Peter says transgenic mouse, he's talking about a mouse that has this transgene that causes it to express more sirtuin-6 than it ordinarily would.

此， 当彼得提到转基时，他指的是携带这种转基的， 这种转基使其表达的Sirtuin-6比通常情况下更多。

For instance, where the transgene is inserted, if it's downstream of an enhancer that's muscle specific, then you can get a, Mao said it overexpresses sirtuins just in muscle.

例如， 转基插入的位置，如果它位于一个肌肉特异性增强子的下游，那么你可以得到，毛教授说它只在肌肉中超量表达sirtuins。
