摘要: 本试验通过实时荧光定量PCR方法来验证SPRN0/0型小鼠和C57BL/6野生型小鼠小脑中小分子RNA(micro-RNA)差异性表达,探讨SPRN基因敲除后小鼠小脑中microRNA相对表达变化。结果表明,与正常标本比,SPRN0/0型小鼠小脑中miR-135a、miR-24-2*、miR-146a、miR-7a、miR-380、miR-448、miR-128和miR-152的表达量均显著下调,其中miR-24-2*下调10倍以上,miR-448、miR-146a、miR-128、miR-380、miR-152均下调2倍以上,miR-135a和miR-7a均下调1倍。由此推断,microRNA的这些变化可能与Shadoo蛋白的生理功能有关,且microRNA靶基因的确立也可以为进一步研究Shadoo蛋白的生理功能提供新的思路。

Abstract: The purpose of this study was to identify different expression of microRNAs between cerebellum of SPRN0/0 mice and C57BL/6 wild mice, and investigate relative expression results of microRNA in cerebrum of SPRN0/0 mice by Real-time PCR technology. The results showed that compared with cerebellum of C57BL/6 wild mice, eight microRNAs were decreased significantly:miR-135a, miR-24-2*, miR-146a, miR-7a, miR-380, miR-448, miR-128 and miR-152. miR-24-2* fold change to more than 10, five microRNAs including miR-448,miR-146a,miR-128,miR-380 and miR-152 fold change to more than 2, miR-135a and miR-7a fold change to more than 1. Thus, we concluded that these changes of microRNAs expression might be involved in Shadoo protein function and the establishment of target genes of microRNAs might provide new ideas for researching Shadoo protein function.
