| 摘 要： | 目的:构建人N-α-乙酰基转移酶10(N-α-acetyltransferase 10, Naa10)基因有效的慢病毒RNAi载体并转染人口腔鳞癌细胞SCC-15,研究其对口腔鳞癌细胞生长的影响。方法:根据人Naa10基因mRNA序列设计合成3个siRNA片段,转染人口腔鳞癌SCC-15细胞株并进行验证,将最有效的干扰序列克隆至pLV-shRNA载体上,测序正确后进行包装,测定病毒颗粒滴度后,将慢病毒感染SCC-15细胞以测定Naa10的表达情况,并通过生长曲线研究干扰Naa10对SCC-15细胞生长的影响。结果:3个靶点的siNaa10 均能有效抑制Naa10基因的表达,其中2号靶点最为有效(P<0.005);重组RNAi质粒pLV-shNaa10经测序证实构建成功, pLV-shNaa10可在293T细胞中成功包装;测定病毒颗粒LV-shNaa10、LV-NC滴度分别为1.2×109 TU/mL和1.0×109 TU/mL;SCC-15细胞感染LV-shNaa10后,Naa10蛋白表达明显降低(P<0.005);干扰Naa10可促进人口腔鳞癌细胞SCC-15的生长。结论:成功构建了Naa10 shRNA慢病毒表达载体,感染人口腔鳞癌细胞SCC-15后,有效抑制了内源性Naa10基因的表达,干扰Naa10可促进SCC-15细胞的生长。

| Abstract: | Objective: To construct the effective lentiviral vector of Naa10 small-interfering RNA, and transfect it into oral squamous cell carcinoma SCC-15 cells so as to investigate its effect on the growth of SCC-15 cells. Methods: Three pairs of siRNA sequences against different parts of Naa10 mRNA were separately transfected into SCC-15 cells. The transfection efficiency was verified, and then the most effective shNaa10 sequence was cloned into pLV-shRNA. pLV-shNaa10 was verified by sequencing and co-transfected into 293T cells to obtain packaged lentivirus particles LV-shNaa10. After viral titer determination, SCC-15 cells were infected with LV-shNaa10 and the expression of Naa10p was detected by Western Blot. Growth curves were used to study the effect of Naa10 knockdown on the growth of SCC-15 cells. Results: Naa10 siRNAs could suppress Naa10 expression and the second siRNA was the most effective (P<0.005). LV-shNaa10 and LV-NC harvested from 293T cells had a titer of 1.2×109 TU/mL and 1.0×109 TU/mL, respectively. After infection with LV-shNaa10, the expression of Naa10 protein in SCC-15 cells was down-regulated (P<0.005), which could in turn markedly facilitate the growth of SCC-15 cells. Conclusion: The lentivirus-mediated Naa10 shRNA was successfully constructed, and knocking down of Naa10 could promote the growth of SCC-15 cells. |
