Abstract

We reported previously that composite DNA constructed from a mammalian plasmid (L factor) and foreign gene can be reestablished as a plasmid in mouse embryonal carcinoma (F9) cells after transfection and the plasmid-bearing F9 cells undergo normal in vitro differentiation in response to retinoic acid, an inducer for F9 cell differentiation. We constructed F9 cells bearing plasmidal L factor DNA in which a reporter (chloramphenicol acetyltransferase; CAT) gene was placed under the control of a differentiation-responsive viral (Moloney murine leukemia virus or simian virus 40) enhancer-promoter. When such plasmid-bearing cells were treated with retinoic acid, the CAT gene was inducibly expressed. These results indicate that mammalian gene expression can be studied with the plasmidal expression vector which is structurally dissociated from complex chromosomes.
