Clonal Origin of Toxic Thyroid Nodules with Constitutively Activating Thyrotropin Receptor Mutations
1 Jan 1998
Abstract excerpt
Constitutively activating TSH receptor mutations have recently been detected in toxic nodules. In vitro studies suggest that mutated receptor signaling constitutively elevates cAMP, which causes hyperfunction and proliferation of thyrocytes. Therefore, toxic nodules with constitutively activating somatic TSH receptor mutations should result from clonal expansion of a single mutated cell. To test this hypothesis,...
