Abstract
The involvement of ribonuclease H (RNase H) in antisense phenomena in intact cells has, to date, only been adequately demonstrated for microinjected Xenopus systems. The significance of RNase H for the antisense effects of oligodeoxynucleotides observed in human and other mammalian cell cultures has remained obscure, in part because of inadequate analytic methods. In this report we show that the "reverse ligation-mediated PCR" (RL-PCR) procedure permits amplification of RNA fragments produced by oligodeoxynucleotide-directed RNase H activity. We have used this procedure to demonstrate RNase H-dependent antisense effects in irreversibly permeabilized (dead) cells and reversibly permeabilized (live) cells.
