P1: the use of PT-HI increased sharply 25 years ago. Human proteins are in great demand for the treatment of lots of diseases. Proteins can be produced in human cell and larger quantities can be produced in bacteria但这些方法都不太好
P2:scientists whether transgenic animals can be used to produce TP with high output but low cost. Ad:1&2 disad: take long time and the transgene may affect animal. 但是目前来看前景很好. transgenic animals could provide alternative source of TP to meet demands.
蛋白质治疗法变得越来越多自从第一次人类胰岛素recombinant。转折虽然能从血液获得,但是治疗非常昂贵和risk。具体举例,蛋白质很难大量生产
转折,蛋白可以在经基因改造的动物内produce,优点:use less animals and specify the sex,缺点:long time and disrupt gene .总结,生物医疗发展很好,前景好。
P1 protein are in great demand but hard to produce
P2 advantage and disadvantage of producing protein from transgenic animal
--advantage:use less animal/reduce the breeding time
--disadvantage:take long time/affect animal
*author: transmic still an alternative source of therapeutic proteins

P1 - Potein therapeutics have increased in use since the introduction of the first recombinatnt protein therapeutic. Human proteins are in great demand for the treatment of diseases. Challenges to produce proteins.
P2 - Human proteins that have post-translational modiications can be produced in the milk of transgenic sheep. People are studying whether trangenic animals can be used to produce therapeutic proteins. The advantages of using transgenic animals. The main disadvantages are long LT and the transgene may affect the animal. Nevertheless, the production continues and scientests predict that the demand will soon exceed the capacity and trangenic animals could help meet the demand.
