Abstract:
Small interfering RNA (siRNA) mediated gene silencing is a promising approach in antiviral therapy. To investigate the antiviral effects of siRNAs on Bovine herpesvirus 1 (BoHV-1) multiplication, we designed and in vitro synthesized two siRNAs (siRNA-1 and siRNA-2) targeting the UL25 gene that is essential for BHV-1 multiplication. siRNA-1 and siRNA-2 inhibited the BoHV-1 multiplication in MDBK cells to a different extent, namely by 11% and 40%, respectively, as demonstrated by virus titers (TCID(50)/ml) determined in cell culture. This indicates that, in general, siRNAs can inhibit BHV-1 multiplication in vitro and could be used also against a BHV-1 infection in vivo following optimization of their application.

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...
