HIV-1 is one of the most variable viruses. The development of gene therapy technology using RNAi for AIDS/HIV-1 treatment is a potential alternative for traditional anti-retroviral therapy. Anti-HIV-1 siRNA should aim to exploit the most conserved viral targets. Using the deep sequencing of potential RNAi targets in 100-nt HIV-1 genome fragments from the clinical HIV-1 subtype A isolates in Russia, we found that the frequencies of all possible transversions and transitions in certain RNAi targets are 3-38 times lower than in adjacent sequences. Therefore, these targets are conserved. We propose the development of these RNAi targets for AIDS/HIV-1 treatment. Deep sequencing also enables the detection of the characteristic mutational bias of RT during the replication of viral RNA.
