You get cystic fibrosis because one protein that's made by your lung epithelium is not expressed properly.

得囊胞性纤维症的病因是,肺上皮细胞产生的一种蛋白,表达不正常

Then, you could get the Hepatitis B protein expressed in your cells.

那样的话,就可以令,乙肝病毒蛋白质在细胞中进行表达

When a gene gets expressed, that means its protein is produced.

一段基因得到表达,就意味着合成它所编码的蛋白

耶鲁公开课 - 生物医学工程探索课程节选

Taking foreign genes, genes that aren't naturally expressed or might not even exist inside a cell and putting them there and putting them there in a way where they work, and by work meaning the gene gets expressed or translated into a protein.

将异源基因,即那些在细胞中原本不表达或者,根本不存在的基因转入细胞并让它们工作,工作就是指让基因持续表达并合成蛋白质

耶鲁公开课 - 生物医学工程探索课程节选

And you could interfere with a translation by degrading messenger RNA, for example. If you had a way to specifically chew up all the RNA molecules that are responsible for making a particular protein, you could stop it from being expressed even though your cell is trying to make it.

而你就可以通过,降解其mRNA来进行干扰,再举个例子,如果你能把表达特定蛋白的RNA,统统揪出来捣毁的话,你也能阻止这段基因表达,哪怕是你的细胞在努力表达这段基因
