Chapter One Local Regulation of Thyroid Hormone Signaling

Thyroid hormone (TH) plays important signaling roles in mammalian growth, development, and thermogenesis. Traditionally its actions were thought to be regulated predominately through modulation of free plasma concentrations, intracellular breakdown by deiodinase enzymes and nuclear processing by thyroid receptors. In the past decade, however, there has been some departure from this classical model, whereby regulatory changes at different levels …
