- 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.
