pIt has recently been shown that adenoviral-mediated expression of peroxisome proliferator-activated receptor γ co-activator-1α (PGC-1 α) 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-1α mediates this stimulation through an evolutionarily conserved region of the G6Pase promoter that binds hepatocyte nuclear factor-4α./p
