<p>A. Cells were transiently transfected with two concentrations of the p<i>NDUFV2</i>-Luc reporter construct (construct) for 24 hrs and analyzed for luciferase activity. B. One hour before the transfection cells were pre-incubated with or without mithramycin (150 nM). The results are means±SD of three experiments normalized for10<sup>6</sup> cells. *p<0.0001.</p
