Abstract

<p>(<b>A</b>) HepG2 cells were transfected with nonspecific siRNA (NS) or si-HIF-1α, and isolated total protein was analyzed by Western blot. α-tubulin was used as a control. (<b>B</b>) HepG2 cells were transfected with pcDNA3-HIF-1α, pcDNA3-ARNT and hERRγ-Luc, respectively. Experiments were conducted in duplicate and data are expressed as the fold activation relative to the control. (<b>C</b>) HepG2 cells were transfected with pcDNA3-HIF-1α and pcDNA3-ARNT and Q-PCR was performed using isolated total RNA. (<b>D–E</b>) HepG2 cells were transfected with nonspecific siRNA (NS) or si-HIF-1α. After transfection, lysates were utilized for luciferase and β-galactosidase assay (D). Q-PCR was performed using isolated total RNA from HepG2 cells (E). All data are representative of at least three independent experiments. Error bars show ± S.E.M. <sup>*</sup><i>P</i><0.05, <sup>***</sup><i>P</i><0.001 by two-tailed Student <i>t</i>-test.</p
