Abstract
The present invention provides novel compositions and methods for suppressing the function or activity of a targeted gene through a novel intracellular piRNA-mediated RNAi mechanism, using RNA-DNA duplex constructs. The invention further provides novel methods and compositions for generating or producing RNA-DNA duplex agents, whose quantity is high enough to be used for the invention's gene silencing transfection and possibly in therapeutics applications. This improved RNA-polymerase chain reaction (RNA-PCR) method utilizes thermocycling steps of promoter-linked DNA or RNA template synthesis, in vitro transcription and then reverse transcription to bring up the amount of RNA-DNA duplexes up to two thousand folds within one round of the above procedure for using in D-RNAi-directed gene silencing.
