摘要: 目的 构建AMFR基因的表达载体和AMFRsiRNA表达载体,观察AMFRsiRNA对AMFR基因表达的影响。方法 采用PCR技术,扩增AMFR基因,并将其插入到带FLAG标签的真核表达载体上;利用RNAi技术,设计并合成了两条针对AMFR基因的siRNA,将其克隆到pSliencer 2.1-U6 neo表达载体上。将构建的AMFR基因表达载体和AMFRsiRNA表达载体共转染人胚肾细胞293T,通过Western blot实验了解AMFRsiRNA对AMFR基因表达的影响。结果 通过双酶切和测序鉴定表明,构建的AMFR基因表达载体和AMFRsiRNA表达载体序列正确;通过Western blot实验证明,构建的AMFRsiRNA能有效抑制AMFR基因的表达。结论 成功构建了AMFR基因表达载体和AMFRsiRNA表达载体,且表达的AMFRsiRNA能有效地抑制AMFR基因的表达。

Abstract: Objective To construct the expression vector of AMFR gene and AMFRsiRNA, and investigate the effect of AMFRsiRNA on the expression of AMFR gene. Methods AMFR gene was amplified by PCR technique and the product of PCR was inserted into the pcDNA3-FLAGC eukaryotic expression vector. Two AMFRsiRNAs were designed by RNAi technique and the AMFRsiRNAs were inserted into the pSliencer 2.1-U6 neo expression vector. Then human embryo kidney 293T cells were co-transfected with the AMFRsiRNA expression vectors and FLAG-tagged AMFR expression vector. The effect of AMFRsiRNAs on the expression of AMFR gene was identified by Western blot. Results The expression vectors of AMFR gene and AMFRsiRNAs were constructed and confirmed by restriction enzyme digestion and DNA sequence analysis. Western blot showed that AMFRsiRNAs could effectively inhibit the expression of AMFR gene. Conclusions The expression vectors of AMFR gene and AMFRsiRNAs were constructed successfully, and the AMFRsiRNAs could effectively inhibit the expression of AMFR gene.
