Role of the cAMP and MAPK pathways in the transformation of mouse 3T3 fibroblasts by a TSHR gene constitutively activated by point mutation.

Abstract excerpt

Constitutive activating mutations of the TSHR gene, have been detected in about 30 per cent of hyperfunctioning human thyroid adenomas and in a minority of differentiated thyroid carcinomas. The mutations activating the TSHR gene(s) in the thyroid carcinomas, were located at the codon 623 changing an Ala to a Ser (GCC-->TCC) or in codon 632 changing a Thr to Ala or Ile (ACC-->GCC or ACC-->ATC). In order to study...
