Abstract

It has recently been shown that adenoviral-mediated expression of peroxisome proliferator-activated receptor gamma co-activator-1 alpha (PGC-1 alpha) in hepatocytes stimulates glucose-6-phosphatase catalytic subunit (G6Pase) gene expression. A combination of fusion gene, gel retardation and chromatin immunoprecipitation assays revealed that, in H4IIE cells, PGC-1 alpha mediates this stimulation through an evolutionarily conserved region of the G6Pase promoter that binds hepatocyte nuclear factor-4 alpha.

摘要

最近研究表明,腺病毒介导的过氧化物酶体增殖物激活受体γ共激活因子-1α(PGC-1α)在肝细胞中的表达可刺激葡萄糖-6-磷酸酶催化亚基(G6Pase)基因的表达。融合基因、凝胶阻滞和染色质免疫沉淀分析相结合的结果显示,在H4IIE细胞中,PGC-1α通过G6Pase启动子上一个与肝细胞核因子-4α结合的进化保守区域介导这种刺激作用。
