摘  要:
研究RNA干扰(RNA interference,RNAi)表达载体对UCP基因的抑制作用。针对鸡解耦联蛋白(avianuncoupling protein,av UCP)基因,构建4种RNAi质粒表达载体(分别称为A、B、C和D号载体)。再经过脂质体法转染成肌纤维细胞,应用荧光定量PCR及流式细胞术检测其对av UCP mRNA及蛋白表达的影响。构建的4种表达载体均抑制了av UCP的mRNA及蛋白的表达,其中转染C号载体的成肌纤维细胞av UCPmRNA表达相当于空白对照组的14.6%,蛋白抑制率达93.7%。RNAi表达载体可以有效的抑制avUCP基因的表达。

摘  要:
To investigate the inhibitory effects of RNAi(RNA interference) expression vector on the expression of avUCP gene.Four siRNA expression vectors(A,B,C and D) were constructed to be aimed directly at avUCP gene.The recombinants were transfected into myofibroblast with liposomes.Expression of avUCP was detected with fluorescence quantitative PCR(FQ-PCR)and flow cytometry.Four kinds of expression vectors could reduce the expression of avUCP mRNA and protein all in myofibroblast.The expression of avUCP mRNA reduced to 14.6% of control group,and the protein inhibition ratio reached 93.7%.The RNAi expression vector can effectively inhibit the expression of avUCP gene.
