Short hairpin RNA targeting NP mRNA inhibiting Newcastle disease virus production and other viral structural mRNA transcription.
Newcastle disease virus (NDV), formally recognized as avian paramyxovirus 1 (APMV-1), is the etiological agent of Newcastle disease (ND), an affliction which can cause severe losses in the poultry industry. Better understanding of the molecular basis of viral structural genes involved with production should contribute significantly toward the development of improved prophylactic and therapeutic reagents to control the infection. Here we show that a short hairpin RNA (shRNA) eukaryotic expression vector targeting nucleocapsid (NP) gene of NDV can potently inhibit NDV production in both primary cells and embryonated chicken eggs. Moreover, shRNA specific for NP abolished the accumulation of not only the corresponding mRNA but also P, HN, F, M gene mRNA. The findings reveal that newly synthesized NP mRNA is essential for NDV transcription and replication, and provide a basis for the development of shRNAs as a prophylaxis and therapy for NDV infection in poultry.
