EXPRESSION OF RECOMBINANT PROTEINS IN THE MILK OF TRANSGENIC ANIMALS 2007-09-02 .txt text/plain 8080 416 48 To date (1997) , probably more than 50 proteins have been expressed in the milk of transgenic mice, rats, rabbits, goats, sheep, pigs, and dairy cows. Transgenes containing sequences of several milk protein genes, reviewed by Maga and Murray (1995) and Echelard (1996) , have been used to direct the expression of exogenous proteins to the lactating mammary gland. Regulatory sequences from several milk-specific genes have been isolated and tested in transgenic animals: ovine ~-lactoglobulin; murine, rat, and rabbit whey acidic protein (WAP); bovine ~-sl casein; rat, rabbit, and goat f~-casein; and guinea pig, ovine, caprine, and bovine ~-lactalbumin. A 17.2 kbp region located upstream of the rabbit WAP gene directs high level expression of a functional human protein variant in transgenic mouse milk High level production of human growth hormone in the milk of transgenic mice: The upstream region of the whey acidic protein (WAP) gene targets transgene expression to the mammary gland ./cache/cord-021393-9loesliv.txt ./txt/cord-021393-9loesliv.txt
