摘要:

背景:特异性下调白细胞介素1β蛋白的表达可以有效缓解外周神经损伤后病理性疼痛。与siRNA相比,shRNA可以更加稳定、高效地抑制目的基因的表达,但是单纯的shRNA无法高效地进入靶细胞中发挥对目的基因的下调作用,而腺病毒载体具有宿主范围广、感染效率高以及能够在宿主细胞中稳定表达等特点。
目的:构建大鼠白细胞介素1β基因的shRNA腺病毒载体并检测其对目的基因表达的影响。
方法:根据NCBI查询获得的大鼠白细胞介素1β基因序列设计3条siRNA并合成相应的shRNA,分别为shRNA1、shRNA2、shRNA3。采用3’和5’单链退火得到的shRNA片段与经过BamHⅠ和EcoRⅠ双酶切的pHBAd/U6/GFP干扰载体连接,构建白细胞介素1βshRNA腺病毒载体穿梭质粒。测序后将穿梭质粒与骨架质粒共转染HEK293细胞,进行白细胞介素1β基因的shRNA腺病毒载体(rAd/shRNAs)的包装与扩增,分别为rAd/shRNA1、rAd/shRNA2、rAd/shRNA3。将rAd/shRNAs感染大鼠H9C2细胞,使用荧光显微镜观察其感染效率,采用Western Blot 检测rAd/shRNAs对目的基因表达的影响。
结果与结论:测序结果显示白细胞介素1β基因的3条shRNA腺病毒载体穿梭质粒中的序列分别与所设计的3条shRNA序列相同;并成功构建了大鼠白细胞介素1β基因的shRNA腺病毒载体(rAd/shRNA1、rAd/shRNA2、rAd/shRNA3)。rAd/shRNA1、rAd/shRNA2、 rAd/shRNA3均可以下调白细胞介素1β的表达,其中rAd/shRNA2的下调效果最明显。

Abstract:

BACKGROUND: Specific down-regulation of interleukin 1 beta (IL-1β) may alleviate the pain behaviors effectively after peripheral nervous injury. Compared with small interference RNA (siRNA), short hairpin RNA (shRNA) could inhibit the expression of target gene more stably and efficiently. However, simple shRNA could not enter target cells to down-regulate target gene efficiently. Adenovirus vectors have wide host range, high infection efficiency and stable expression in host cells.
OBJECTIVE: To construct recombinant adenovirus vector expressing shRNA targeting IL-1β gene and detect its effect on the expression of target gene.
METHODS: Three siRNAs were designed on the basis of the nucleotide sequence of IL-1β obtained from NCBI 
and then three shRNAs (shRNA1, shRNA2 and shRNA3) were synthesized. The annealed shRNA product and adenovirus vector pHBAd/U6/GFP digested by BamH I and EcoR I were connected to construct the recombinant adenovirus vector shuttle plasmid expressing shRNA targeting IL-1β. After sequencing, HEK 293 cells were co-transfected by the shuttle plasmid and skeleton vector, and three recombinant adenovirus vector expressing shRNA targeting IL-1β (rAd/shRNA1, rAd/shRNA2 and rAd/shRNA3) were packaged and amplified. Rats H9C2 cells were infected by recombinant adenovirus vector expressing shRNA targeting IL-1β and fluorescence microscope was used to observe the infection efficiency. The effect of recombinant adenovirus vector expressing shRNA targeting IL-1β on the expression of target gene was detected by western blot assay.
RESULTS AND CONCLUSION: The sequencing results showed that the sequences of three shRNAs adenovirus vector shuttle plasmid were consistent with the sequences of three designed shRNAs. rAd/shRNA1, rAd/shRNA2 and rAd/shRNA3 were constructed successfully. rAd/shRNA1, rAd/shRNA2 and rAd/shRNA3 could down-regulate the expression of IL-1β in rat H9C2 cells and the down-regulation effect of  rAd/shRNA2 was the most significant.
