While Fuhrer et al. [13] found elevated levels of ETS1 in PTC when compared to benign thyroid nodules and normal thyroid tissues, Nakayama et al. [14] observed strong expression of ETS1 in the majority of malignant thyroid tumors, a minority of benign thyroid tumors, and no expression in normal thyroid follicular cells. Here, ETS1 is linked to benign thyroid gland neoplasm.
