Extracellular ATP modulates several biological processes via activation of plasma membrane receptors (P2Rs) in normal human thyrocytes (NT). We characterized P2Rs expression and function in two thyroid cancer cell lines: FB1 (anaplastic cancer) and FB2 [papillary cancer (PTC)]. P2Rs expression was evaluated by RT-PCR and WB, intracellular Ca2+changes by fluorimetric technique (Fura2-AM), IL-6 release by ELISA, intracellular [i(ATP)] and extracellular ATP [...
