We conclude that ( 1 ) TRalpha is the major TR regulating Hr expression in the cerebellum of young mouse pups ; ( 2 ) TH upregulates Hr and SMRT and downregulates SRC 1 ; ( 3 ) NcoR and SRC 3 may not be regulated by TH in the cerebellum at the transcriptional level ; and ( 4 ) autoregulation of TH action may be mediated through TH dependent expression of the cofactors necessary for TH action in the cerebellum and may be developmentally specific . . ^^^

To determine whether coactivators and corepressors have the capacity to modulate the relative agonist / antagonist activity of 4HT , ER dependent gene expression was measured in the absence or presence of expression vectors for SRC 1 ( steroid receptor coactivator 1 ) or SMRT ( silencing mediator of retinoic acid and thyroid hormone receptors ) . ^^^ In Hep G 2 cells in which 4HT is an agonist , exogenous SRC 1 enhanced estradiol ( E 2 ) and 4HT stimulated transcription in a dose dependent manner , while SMRT overexpression strongly reduced basal and 4HT stimulated gene expression with no effect on E 2 activity . ^^^ To assess whether relative coactivator and corepressor expression within a given cell could modulate the balance of 4HT agonist / antagonist activity , SRC 1 and SMRT were coexpressed . ^^^ SMRT overexpression blocked SRC 1 coactivation of 4HT stimulated gene expression and preferentially inhibited 4HT agonist activity whether or not exogenous SRC 1 was present . ^^^
