Cytoplasmic beta-actin promoter produces germ cell and preimplantation embryonic transgene expression
Mol Reprod Dev.
1993 Feb.
Abstract
The cytoplasmic beta-actin promoter, commonly used as strong promoter in many gene regulation studies, produces a pattern of male germ cell and preimplantation, embryonic gene expression in transgenic mice. In seven of ten expressing transgenic lines, a chicken beta-actin-lacZ fusion gene was expressed in adult testes. In addition, five of the ten lines demonstrated transgene expression in the preimplantation mouse embryo. This is the first example of transgene expression at the stages of both gamete and early embryo. Overall, the site or transgene integration appeared to influence transgene expression in adult tissues.
