The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid cells. Its expression in thyroid tumors allows the use of radioactive iodine (131I) as co-adjuvant therapeutic tool to eliminate remaining tumor cells and metastases after total thyroidectomy. Nevertheless, certain subsets of patients with advanced forms of thyroid cancer lose the ability to respond to radioiodine therapy, which drastically reduces their survival rates. Recent studies ...

Introduction: Identification of molecular markers with a reliable prognostic value may greatly improve the management of patients with papillary thyroid carcinoma (PTC). Rac1b, a hyperactive splice variant of the small GTPase Rac1, was found to be overexpressed in colorectal, breast and lung cancer. It has been shown to sustain tumor cell survival in colorectal cancer and was reported to have a key role in the malignant progression of breast and lung tumors. The Rac1b tumorige...
