Abstract:
We report here a new method for inhibition of RNA viruses induced by dsDNA. We demonstrated that both long dsDNA molecules and short interfering DNA with a sequence complementary to that of viral RNA inhibited tobacco mosaic virus expression and prevented virus spread. Also, the expression of the HIV-1 gp41 gene in HeLa cells was inhibited by complementary short interfering DNA. We showed that Dicer processed dsDNA, which suggests activation of the cellular machinery involved in silencing of RNA. For the silencing of viral RNA effected with dsDNA, we coined the term DNA interference technology.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
