Abstract excerpt
Expression of mutated versions of the p53 gene deranged the differentiation program of thyroid cells and resulted in deregulated growth. Specifically, p53 mutants in several residues of the DNA-binding region induced thyrotropin (TSH) -independent growth and inhibition of the expression of thyroi...
