|Figure 2: Model fit (curve) to data (open points) on hCAR activation in luciferase-reporter
human HepG2 cells cultured for 24 hours at the indicated 4-aminoazobenzene concentration,
which were reported normalized to a scale of 0% for DMSO control wells (plotted at
0 µM) and 100% (the maximum CITCO-induced activity). Error bars = ±1 standard deviation
of the mean (SDM), involving 37 replicates/concentration. Dotted line = background
in DMSO-exposed cells.
