摘要 目的:构建真核表达载体pRK5-A53T-SNCA-NLS、pRK5-A53T-SNCA-NES,瞬时转染SH-SY5Y细胞。方法:PCR扩增法获得含有SalI和NotI的目的片段A53T-SNCA-NLS、A53T-SNCA-NES,SalI、NotI双酶切载体pRK5,线性pRK5与目的片段经ligation high连接,酶切、PCR鉴定重组质粒pRK5-A53T-SNCA-NLS、pRK5-A53T-SNCA-NES。重组质粒通过Lipofactamine2000转染SH-SY5H细胞,免疫荧光法鉴定瞬转细胞。结果:真核表达载体pRK5-A53T-SNCA-NLS、pRK5-A53T-SNCA-NES构建成功,NLS、NES能介导突变基因A53T-SNCA翻译的α-synuclein蛋白在核内表达或胞质表达。结论:基因A53T-SNCA翻译的突变α-synuclein蛋白核内高表达或胞质高表达可能是家族性帕金森氏病发病机制中关键因素之一。
