Thyroid hormone (T3) responsiveness of the PEPCK promoter in vivo was examined in both PEPCK/bGH(460) and PEPCK/bGH(335) mouse lines. Transgenic and non-transgenic littermates were treated with methimazole or PTU for 6 or 4 weeks, respectively, then treated +/- T3 for 10 days. In PEPCK/bGH(460) and PEPCK/bGH(355) transgenic mice, the bGH mRNA was decreased by 65% and 46%, respectively, in hyperthyroid mice when compared to euthyroid controls. Endogenous PEPCK mRNA was decreased by 33% in hyperthyroid non-transgenic mice. The conclusion of this study is that chronic hyperthyroidism in mice inhibits PEPCK-directed expression of the transgene when either the -460/+73 or the -355/+73 promoter/regulatory elements are used.
