<p>A. T3-induced <i>Hr</i> expression is detected earlier and stronger in transfected C17.2/TRα1 cells (black bars) than in non-transfected cells (white bars), *p<0.05, Student’s t-test difference between non-transfected cells and C17.2/TRα1 cells. B. The level of change in expression induced by T3 and measured by Q-RT-PCR in C17.2/TRα1 cells is indicated for each target gene, using non-treated cultures as reference (represented as log2 of the fold change). White bars indicate T3 treatment in proliferative medium (containing serum), black bars indicated T3 treatment in serum-deprived medium allowing for differentiation. Most genes show a response only in serum-deprived medium, *p<0.05, Student’s t-test, difference between serum containing and serum deprived cultures.</p
