Knockdown of FLT4, Nup98, and Nup205 cellular genes effectively suppresses the reproduction of influenza virus strain A/WSN/1933 (H1N1) in vitro
CONCLUSION: We identified a number of genes such as FLT4, Nup98, and Nup205, the decrease in the expression of which can effectively suppress viral reproduction. The original siRNA sequences were also obtained. These results are important for the creation of therapeutic and prophylactic agents, whose action is based on the RNA interference mechanism.PMID:35339191 | DOI:10.2174/1871526522666220325121403

Current Development of siRNA Bioconjugates: From Research to the Clinic
In this study, it was shown that the main factor determining the nature of the biodistribution of conjugates is their lipophilicity. Conjugates of siRNA with lower lipophilicity; i.e., derivatives of retinoic acid, lithocholic acid, and docosahexanoic acid with greater efficiency than cholesterol conjugates accumulated in the kidneys, bladder, and lungs of the mouse after subcutaneous injection (Biscans et al., 2018). This fact is consistent with previous data that showed that more lipophilic conjugates bind more efficiently to serum components, and thus are not excreted by the kidneys (Wolfrum et al., 2007; Osborn et al.,...

Mutation Frequencies in HIV-1 Genome in Regions Containing Efficient RNAi Targets As Calculated from Ultra-Deep Sequencing Data.
Abstract 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 develo...
