Gene expression changes with unliganded TRs.

<p><b>A</b>. Numbers of genes that meet fold cutoffs for activation/repression and statistical significance in response to unliganded TR expression in HepG2 cells, TRα and TRβ expressing cells were compared to parental. <b>B</b>. HeLa cells, TRα and TRβ expressing cells after doxycycline withdrawal to induce TRs versus doxycyclin treated cells. Similar results were obtained in comparisons with parental HeLa cells (not shown). <b>C</b>. Plots of fold induction/repression by TRβ (y-axis) versus TRα (x-axis) in HepG2 cells. <b>D</b>. Plots of fold induction/repression by TRβ (y-axis) versus TRα (x-axis) in HeLa cells.
