    • A non-human transgenic mammalian animal, as described above, contains an exogenous double stranded DNA sequence stably integrated into the genome of the animal, which comprises cis-acting regulatory units operably linked to a DNA sequence encoding human Factor VIII protein and a signal peptide, where the cis-acting regulatory units are active in mammary gland cells and the signal peptide is active in directing newly expressed Factor VIII into the milk of the animal. The promoter may be a milk protein promoter such as for whey acidic protein, casein, lactalbumin, or beta-lactoglobulin promoter. The transgenic mammals are preferably farm animals, for example, cows, goats, sheep, rabbits and pigs. Concurrent expression of a gene for human von Willebrand's Factor into milk may be used to stabilize newly-secreted Factor VIII.
    • 如上所述的非人转基因哺乳动物包含稳定整合到动物基因组中的外源双链DNA序列,其包含与编码人因子VIII蛋白的DNA序列可操作地连接的顺式作用调节单元和信号肽 其中顺式作用调节单元在乳腺细胞中是活性的,并且信号肽在将新表达的因子VIII引导到动物的乳中是有活性的。 启动子可以是乳蛋白质启动子,例如用于乳清酸性蛋白质,酪蛋白,乳清蛋白或β-乳球蛋白启动子。 转基因哺乳动物优选为农场动物,例如牛,山羊,绵羊,兔和猪。 将人血管性血友病因子的基因同时表达为牛奶可用于稳定新分泌的因子VIII。
