Abstract
Antisense RNA, transcribed intracellularly from constitutive expression cassettes, inhibits the replication of the human immunodeficiency virus type 1 (HIV-1) as demonstrated by a quantitative microinjection assay in human SW480 cells. Infectious proviral HIV-1 DNA was co-microinjected together with a fivefold molar excess of plasmids expressing antisense RNA complementary to a set of ten different HIV-1 target regions. The most inhibitory antisense RNA expression plasmids were targeted against a 1 kb region within the gag open reading frame and against a 562 base region containing the coding sequences for the regulatory viral proteins tat and rev. Experimental evidence is presented that the antisense principle is the inhibitory mechanism in this assay system.
