Type 3 Iodothyronine Deiodinase Is Highly Expressed in the Human Uteroplacental Unit and in Fetal Epithelium
1 Mar 2003
Abstract excerpt
Type 3 iodothyronine deiodinase (D3) is the major physiologic inactivator of thyroid hormone. This selenoenzyme, previously identified in human placenta and brain, catalyzes the inner-ring deiodination of T(4) to reverse T(3) and T(3) to 3, 3'-diiodothyronine, both of which are biologically inactive. We analyzed D3 expression in several human adult and fetal tissues by immunohistochemistry and correlated the...
