摘要: 目的 构建CD147siRNA表达载体,分析CD147在皮肤肿瘤浸润和转移中的作用机制。方法 根据基因库上的CD147 cDNA序列,设计并合成两端含有酶切位点的64个碱基的寡核苷酸链。寡核苷酸链退火后用T4DNA连接酶连接到线性化的pSUPER质粒中,并对重组质粒(命名为pSUPER/CD147 siRNA)进行酶切、PCR及测序鉴定。结果 PCR扩增片段与预期结果相符,双酶切证实CD147 siRNA表达载体克隆构建成功,插入片段测序结果与合成的siRNA结果一致。结论 成功构建CD147 siRNA表达载体,CD147可为治疗肿瘤开辟新途径。

Abstract: Objective To construct CD147 siRNA expression vector in order to analyze the role of CD147 in the invasion and metastasis of tumors derived from skin. Methods According to CD147 cDNA sequence in the Genebank,apair of 64-nt oligonucleotides,each containing the sites of restriction endonuclease at both ends,were designed and synthesized.Oligonucleotides were annealed and ligated with linearized pSUPER by T4DNA ligase.The recombinants (named pSUPER/CD147 siRNA) were finally sequenced and identified by PCR and restriction end onuclease digestion. Results CD147 siRNA expression vector was successfully co nstructed and identified by double endonuclease digestion.Sequence analysis of inserted fragment revealed the same sequence as synthesized siRNA oligonucleotid es. Conclusions CD147 siRNA expression vector has been successfully constructed,which paves the way for studying the role of CD147 in the invasion and metastasis of tumor cells derived from skin as well as in tumor therapy.
