摘要 目的:构建抑癌基因PTEN的表达载体并在LOVO细胞中表达。方法:从人外周血中提取总RNA,通过RT-PCR扩增出PTEN基因片段,将PTEN基因连入pLenti6/V5载体。测序鉴定后,经脂质体转染入LOVO细胞,对细胞株进行RT-PCR和Western blot检测。结果:DNA测序证实pLenti6/V5-PTEN表达载体为阳性克隆;该表达载体转染LOVO细胞后上调了PTEN mRNA和蛋白的表达。结论:成功构建了pLen-ti6/V5-PTEN表达载体,为进一步研究PTEN在LOVO细胞中的功能奠定了基础。 Objective:To construct expression vector of PTEN gene and express the gene in LOVO cells.Methods: Extracted total RNA from human peripheral blood and amplified PTEN cDNA by RT-PCR,then the cDNA was inserted into vector pLenti6/V5.The positive clones were verified by sequencing and transfected to LOVO cells by lipofectamine.RT-PCR and Western blot were performed.Results: The pLenti6/V5-PTEN expression vector was constructed successfully after the confirmation by sequencing analysis.The pLenti6/V5-PTEN expression vector was transfected to LOVO cells,the mRNA and protein level of PTEN were upregulated obviously.Conclusion: The pLenti6/V5-PTEN was constructed successfully,and it provides a condition for the further investigation of PTEN function in LOVO cells.
