abstract：:Receptor tyrosine kinases (RTKs) are cell-surface molecules that transduce signals for cell growth and differentiation. The RTK encoded by the c-ret proto-oncogene is rearranged and constitutively activated in a large proportion of thyroid papillary carcinomas, and germ-line point mutations in c-ret seem to be respons...
