1 7709602 TTF-1 is implicated as a critical autoregulatory component in both positive and negative regulation of the TSHR and appears to be the link between TSH, the TSHR, TSHR-mediated signals, TG and TPO biosynthesis, and thyroid hormone formation.
2 7709602 Differentially regulated expression of the TSHR and TG by cAMP and insulin depend on differences in the specificity of the TTF-1 site, that is, the lack of Pax-8 interactions with the TSHR, and the IRE sites.
3 7565801 An element, -186 to -176 base pairs (bp), in the minimal TSH receptor (TSHR) promoter binds thyroid transcription factor-1 (TTF-1) and is important for both constitutive expression and TSH/cAMP-induced negative autoregulation of the TSHR in thyroid cells.
4 7565801 Transfection experiments indicate that full, constitutive TSHR gene expression in FRTL-5 thyroid cells requires the binding of both SSBPs and TTF-1, since mutation of either element halves thyroid-specific promoter activity, whereas mutation of both decreases promoter activity to values near those of a control vector.
5 7565801 In sum, full, constitutive expression of the TSHR in thyroid cells requires TTF-1 and the SSBPs to bind separate, contiguous elements on the TSHR promoter.
6 7565801 The role of the SSBP and TTF-1 sites in constitutive TSHR expression and in TSH/cAMP-induced negative regulation of the TSHR is, therefore, additive and independent.
7 8923467 Mutation analyses indicate that it is functionally distinct from the TTF-1 element and is important for the constitutive expression and TSH/cAMP-induced negative autoregulation of the TSHR in thyroid cells but only constitutive expression in nonthyroid cells.
