原癌基因USP22启动子的克隆及转录活性分析
Cloning of the USP22 Oncogene Promoter and Analysis of Its Transcription Activity
摘要
Abstract
Abstract Objective To clone a part of the promoter region of human USP22 oncogene.and to investigate its transcription activity. Methods We identified the USP22 transcription start site (TSS) by 5' RACE (5' rapid amplification of cDNA ends) analysis,and then amplified its 5' UTR fragment (-2 828-+52) containing TSS. The PCR products were inserted into luciferase reporter vector pGL3-Basic. The recombinant plasmids were co-transfected into HepG2 cells and Hela cells with plasmid pRL-TK. The activities of luciferase were measured by dual luciferase reporter system. Results The USP22 gene's TSS was determinated. The electrophoresis analysis of restriction enzyme digestion and DNA sequencing verified that the fragment (-2 828-+52) was successfully amplified and inserted into pGL3-Basic. After the recombinant plasmids transfected, luciferase was highly expressed in HepG2 cells and Hela cells. Conclusion The recombinant vector containing LJSP22 promoter is constructed successfully,which provides a basis for further exploring the regulation mechanism of USP22 expression.关键词
