To explore the anti-HSV-1 effect of silencing gD gene expression by RNA interference, five 21-nucleotide duplex small interfering RNAs(siRNAs) targeting the HSV1 gD sequence were designed and the gD-EGFP fusion gene expression vector was constructed, then co-transfected into Vero cell, and screened the effective siRNA through analyzing the intensity of the EGFP fluorescence. Finally, the anti-HSV1 effect was confirmed by plaque reduction assay, real-time PCR and daughter virus titration of HSV1 infected Vero cells transfected with siRNAs. The study demonstrated that siRNAs could effectively and specifically inhibit gD gene expression in HSV1-infected cells, but only had a little effect on HSV1 infection, so taking gD as the target of siRNA against HSV1 needs further study.
