Thyroid hormone acts predominantly by combining with high affinity nuc
lear receptors and modifying gene expression. There are two thyroid ho
rmone receptor genes, alpha and beta, with multiple isoforms that are
differentially expressed developmentally and in adult tissues. Thyroid
hormone-regulated genes have been identified in a number of tissues,
and their expression is altered in thyrotoxicosis. Correlations betwee
n the clinical manifestations of thyrotoxicosis and modified gene expr
ession can be made in some tissues.
