PPARγ基因靶向shRNA真核表达载体的构建及表达
Construction and expression of eukaryotic expression plasmids of shRNA targeting the PPARγ gene
摘要
Abstract
Aim To construct eukaryotic expressing plasmids of short hairpin RNA ( shRNA) targeting the PPAR γ gene and to evaluate their inhibitory effect on PPARγ expression in human umbilical veinendothelial cells ( HUVECs). Methods Three pairs of complementary shRNA oligonucleotides targeting the PPARγ gene were designed , synthesized, annealed and inserted into the pGPU6/GFP/Neo plasmid. The recombinant plasmids were identified by restriction enzyme analysis and sequence anal -ysis. The inhibitory effect of recombinant plasmids on PPAR γ expression in HUVECs was detected by Western blot. ResultsAfter restriction enzyme analysis and sequence analysis , three eukaryotic expression plasmids of shRNA targeting the PPAR γ gene were successfully constructed. Western blot analysis showed that pGPU6/GFP/NeoshRNAPPARγ3 reduced PPARγ expression by 63.2% in HUVECs induced with high glucose. Conclusion Three eukaryotic expression plasmids of shRNA targeting the PPARγ gene are successfully constructed. These recombinant plasmids can efficiently inhibit PPARγ expression in HUVECs.关键词
