Characterization of an up-stream thyroid transcription factor-1-binding site in the thyrotropin receptor promoter.

abstract：:IGF1-a small, single-chain, secreted peptide in mammals-is essential for normal somatic growth and is involved in a variety of other physiological and pathophysiological processes. IGF1 expression appears to be controlled by several different signaling mechanisms in mammals, with GH playing a key role by activating an...

abstract：:Thyroid dysfunction during human pregnancy is closely related to serious pregnancy outcome. However, the regulation and function of thyroid hormones during early pregnancy are largely unknown. We found that type II deiodinase, an enzyme converting T4 to activated T3, is highly expressed in the mouse uterus on days 3 a...
