纽卡斯尔病病毒(Newcastle disease virus,NDV)是纽卡斯尔病(Newcastle disease,ND)的病原体,其正式名称为禽副粘病毒1型(Avian Paramyxovirus 1,APMV-1)。更好地了解与生产有关的病毒结构基因的分子基础,将大大有助于开发更好的预防和治疗试剂来控制感染。在这里,我们表明针对NDV核壳(NP)基因的短发夹RNA(shRNA)真核表达载体可以有效抑制NDV在原代细胞和鸡胚中的产生。此外,针对NP的特异性shRNA不仅消除了相应mRNA的积累,而且还消除了P、HN、F、M基因mRNA的积累。结果表明,新合成的NP mRNA对NDV的转录和复制至关重要,为开发shRNA作为NDV感染的预防和治疗药物提供了基础。
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.
