Differential Regulation of Direct Repeat 3 Vitamin D 3 and Direct Repeat 4 Thyroid Hormone Signaling Pathways by the Human TR4 Orphan Receptor* Yi-Fen Lee , Win-Jing Young , Differential Regulation of Direct Repeat 3 Vitamin D3and Jun 04, 1999 · This contrasting and differential regulation by TR4 could be because of different DNA-protein or protein-protein interactions. When compared, we found the K d values of TR4 to DR3VDRE and TR4 to DR4T 3 RE to be very similar (1.32 versus 2.0 n m). This result eliminates the possibility that a different binding capacity between TR4 and DR3 or DR4 results in the distinctive regulation.

Differential regulation of monocarboxylate transporter 8

Objective:Thyroid hormone (TH) transporters are eed in thyrocytes and most play a role in TH release. We asked whether eion of the monocarboxylate transporter 8 (MCT8) and the L-type amino acid transporters LAT2 and LAT4 is changed with thyrocyte dedifferentiation and in hyperfunctioning thyroid tissues. Differential regulation of three thyroid hormone Differential regulation of MMP genes by thyroid hormone receptors. Although all three MMP genes are thyroid hormone (T 3) response genes, their regulation by T 3 differs.

Differential regulation of thyroid hormone receptor Apr 01, 1991 · Results revealed that there is differential regulation of the individual TRs by TRH at the pretranslational level. The mRNA for the pituitary-specific form of TR, TR beta-2, was down-regulated by 60% by TRH in GH3 cells, while that of its alternative splice product, TR beta-1, was unchanged.

Differential regulation of thyroid hormone receptor

Aroclor 1254 exposure for 48 h enhanced T 3 -mediated PRL production, but BPA down-regulated. These results suggest that the EDs (TCDD, Aroclor 1254 and BPA) could differentially bind to TR and distinctly regulate the action of TR function, even though EDs are structurally similar. Differential regulation of thyroid hormone receptor It is well known that endocrine disruptors (EDs) act as anti-estrogenic agents and affect the function of reproductive organ. EDs are also thought to affect thyroid hormone (TH) system which is important for biological functions such as growth, development and metabolism. However, it is still not clear how EDs are able to regulate TH receptor (TR)-mediated functions.

Differential regulation of thyrotropin-releasing hormone Apr 15, 1992 · GH3 cells have been well-known to possess T3 receptors. Moreover, the down regulation of TRH-R binding by thyroid hormone has been reported in GH3 cells (4). Therefore, it is likely that the decrease of TRH-R binding in GH3 cells after incubation with T3 may be mediated by translational or post-translational mecha nisms.

Fundamentally Distinct Roles of Thyroid Hormone Receptor

The thyroid hormones, T 3 and T 4, profoundly influence human development and metabolic regulation. Thyroid hormone (TH) production is regulated by a feedback system involving TSH secreted by the pituitary thyrotrophs and TRH secreted by discrete nuclei in the hypothalamus. Identical gene regulation patterns of T3 and selective Synthetic selective thyroid hormone (TH) receptor (TR) modulators (STRM) exhibit beneficial effects on dyslipidemias in animals and humans and reduce obesity, fatty liver, and insulin resistance in preclinical animal models. STRM differ from native TH in preferential binding to the TR subtype vs. T
