โœฆ Synopsis


An expression vector was constructed containing the entire bovine papilloma virus (BPV-1) genome and part of the ~-actin gene of Xenopus laevis cloned in the antisense orientation into the neomycin resistance gene under the control of the herpes simplex virus (HSV) thymidine kinase (TK) promoter. When this vector is microinjected into X. laevis embryos it replicates extrachromosomally, at least up to the tadpole stage, and a fusion RNA is synthesized after the mid blastula transition (MBT). The expression of the antisense gene results in a morphological abnormality of somites demonstrating that antisense RNA generated by an episomal replicating expression vector can inhibit the expression of a selected gene during early embryogenesis of X. laevis.

We studied the effects in Xenopus embryos of overexpression of antisense RNA complementary to the messenger RNA of eFGF. We show that the expression of sense RNA can be severely depressed in the presence of an excess of antisense RNA. This occurs by both partial destruction of the message and by a d
