中文摘要: |
VP15是南美白对虾WSSV病毒的一个核衣壳蛋白基因。采用体外干扰实验筛选对VP15具有针对性的siRNA。实验构建了真核表达载体pEGFP-VP15,并将设计的siRNA以及pEGFP-VP15共转染BHK细胞。采用Westernblot方法检测GFP-VP15融合蛋白的表达,半定量RT-PCR方法检验siRNA抑制VP15基因转录的效果。实验结果表明,pEGFP-VP15在PK细胞正常表达,设计的3对siRNA对GFP-VP15的mRNA转录均有不同程度的干扰效果;其中,siRNA1的干扰效果最为显著。实验结果为下一步对虾体内干扰WSSV病毒复制研究以及筛选更多的特异siRNA建立基础。 |
英文摘要: |
VP15,a structure gene for virion nucleocapsid. In order to screen out specific siRNA for VP15,an vitrovector named pEGFP-VP15 was constructed,and then siRNA targeting VP15 and pEGFP-VP15 were cotransfected into PK cell. The expression of pEGFP-VP15 was verified by Western blot,and the interference effect toVP15 in transcription was detected by semi-quantitative reverse transcription and polymerase Chain reaction. Our study here demonstrates that pEGFP-VP15 can be expressed in PK cell correctelly,the mRNA transcription for GFP-VP15 was suppressed by three pairs siRNA specifically,and the siRNAl made the most remarkable effect.Our study results would provide a system for choosing specifical siRNA for VP15 and also provide a foundation for further research such as suppressing the wssv reproduce in shrimp. |
