Abstract
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.
