PGC-1α辅助激活人PEPCK基因转录
【目的】构建人磷酸烯醇式丙酮酸羧激酶(PEPCK)基因启动子荧光素酶报告质粒PGL3-hPCK-luc，并探讨过氧化物酶体增殖物活化受体γ辅助激活因子1α(PGC-1α)在转录因子肝细胞核因子4α(HNF4α)介导下对人PEPCK基因启动子活性的影响【方法】从人全血基因组DNA中克隆PEPCK启动子基因片段，并重组进荧光素酶报告载体PGL3-basic，将pcDNA3.1-PGC-1αpcDNA3.0-HNF4α表达质粒与PGL3-hPCK-luc按不同组合共转染进人肝癌细胞株HepG2细胞或正常人肝细胞株LO2细胞,培养48 h后检测细胞裂解液中荧光素酶活性【结果】通过酶切鉴定及测序证明扩增...
