    • A method of producing foreign gene products which comprises (1) transforming animal cells either (a) by using two plasmids, namely a plasmid containing the MMTV LTR and a foreign gene encoding a physiologically active substance inserted therein downstream from the LTR and a plasmid containing the LTR and a glucocorticoid receptor protein gene inserted therein downstream from the LTR, or (b) by using one plasmid comprising the LTR, a glucocorticoid receptor protein gene located downstream from the LTR, another LTR and a foreign gene encoding a physiologically active substance located downstream from the latter LTR, and (2) cultivating the transformed animal cells in a medium containing glucocorticoid in an amount effective for inducing mRNA transcription.
    • 一种生产外源基因产物的方法,其包括:(1)通过使用两种质粒(即含有MMTV LTR的质粒和编码在LTR下游插入的生理活性物质的外源基因)的质粒转化动物细胞,以及含有 LTR和在LTR下游插入的糖皮质激素受体蛋白基因,或(b)通过使用包含LTR的一种质粒,位于LTR下游的糖皮质激素受体蛋白质基因,另一LTR和编码生理活性物质的外源基因 在后一种LTR的下游,和(2)在含有有效诱导mRNA转录的量的含有糖皮质激素的培养基中培养转化的动物细胞。
