Abstract
Introduction: Influenza is an acute respiratory viral infectious disease caused by the influenza viruses. Current preventive and therapeutic approaches are of great anti-epidemic importance, but there are a number of problems, such as the rapid emergence of resistant strains, the lack of cross-immunity and the effectiveness of vaccines. One of the approaches to the development of anti-influenza agents is the use of RNA interference and small interfering RNAs complementary to the mRNA target of viral and cellular genes. Aim ‒ to evaluate the prophylactic anti-influenza effect of siRNAs directed to the cellular genes NXF1, PRPS1 and NAA10 in an in vitro model.
Materials and methods: Antigenic variants of influenza A virus: A/California/7/09 (H1N1), A/WSN/33 (H1N1) and A/Brisbane/59/07 (H1N1); cell cultures A549 and MDCK. The study was performed using molecular genetic (transfection, NC isolation, RT-PCR-RV) and virological (cell culture infection, titration by visual CPE, viral titer assessment using the Ramakrishnan method) methods.
Results: It was shown that siRNAs targeting the cellular genes NXF1, PRPS1 and NAA10, when used prophylactically in cell culture at a concentration of 0.25 μg per well, during infection with influenza virus strains A/California/7/09 (H1N1), A/WSN/33 (H1N1) and A/Brisbane/59/07 (H1N1) at a multiplicity of infection of 0.01, reduced viral replication to a level of 220 TCID50 per 1 ml of cell medium, whereas in control untreated cells the viral yield was ~106 TCID50 per 1 ml of medium.
Conclusions: Reproduction of influenza A viruses directly depends on the protein products of the NXF1, PRPS1, and NAA10 genes. Reduced expression of these genes disrupts the life cycle and activity of influenza viruses. Such an approach can potentially be studied and used for closely and distantly related representatives of other virus families.
