abstract：:Transforming growth factor-beta1 (TGF-beta1) is a multifunctional cytokine that is thought to play a major role in the regulation of growth and differentiation of thyroid cells. However, little is known of its detailed mechanisms of action in thyrocytes. We have therefore studied the molecular mechanisms of TGF-beta1 ...
