Smyd1干扰真核表达质粒及其稳定转染H9c2细胞系的构建
Construction of RNAi Recombinant Eukaryotic Expression Vectors of Smyd1 and Establishment of Its Stably Transfected H9c2 Cell Lines
摘要
运用RNA干扰技术(RNA interference RNAi)构建pSUPER.retro-Smyd1真核表达质粒, 经鉴定后用脂质体法转染H9c2细胞, 通过G418筛选出稳定表达pSUPER.retro-Smyd1的细胞系, 最后经Western blot及RT-PCR实验鉴定其干扰效果。经鉴定, 通过H9c2细胞系构建的pSUPER.retro-Smyd1干扰细胞系的干扰效果显著。因此, 本实验成功构建了Smyd1干扰真核表达质粒及其稳定转染的H9c2细胞系, 为进一步研究Smyd1基因在心脏发育中的作用奠定了良好的实验基础。
Abstract
The eukaryotic expression vector of pSUPER-Smyd1 was constructed for RNA interference. After verification, we transfected the plasmids into H9c2 cells by Lipofectamine 2000. After screening by G418,stable transfected cell lines were established to express pSUPER-Smyd1. Finally, the interferential effect was demonstrated by Western blot and RT-PCR. In a word, RNAi recombinant eukaryotic expression vector of Smyd1 was successfully Constructed and the establishment of its stably transfected H9c2 cell lines laid a solid experimental foundation for the further studies on the function of Smyd1 gene of the heart development.
