- Although most patients with papillary thyroid cancer (PTC) have favorable outcomes, some have advanced PTC that is refractory to external beam radiation and systemic chemotherapy. Galectin-3 (Gal-3) is a beta-galactoside-binding protein with antiapoptotic activity that is consistently overexpressed in PTC. The purpose of this study is to determine if Gal-3 inhibition promotes apoptosis, chemosensitivity, and radiosensitivity in PTC. PTC cell lines (8505-C and TPC-1) and human ex vivo PTC were treated with a highly specific small molecule inhibitor of Gal-3 (Td131_1). Apoptotic activity was determined by flow cytometric analysis as well as caspase-3 and PARP cleavage. The minimum inhibitory concentrations of Td131_1 and doxorubicin were determined, and their combined effects were measured to test for synergistic activity. The effects of Td131_1 on radiosensitivity were determined by a clonogenic assay. Td131_1 promoted apoptosis, improved radiosensitivity, and synergistically enhanced chemosensitivity to doxorubicin in PTC cell lines. In PTC ex vivo, Td131_1 treatment alone induced the cleavage of caspase-3 and PARP. Td131_1 and doxorubicin together activated apoptosis in PTC ex vivo to a greater degree than their combined individual effects. Td131_1 activated apoptosis and had synergistic activity with doxorubicin in PTC. We conclude that Gal-3 targeted therapy is a promising therapeutic strategy for advanced PTC that is refractory to surgery and radioactive iodine therapy. (Mol Cancer Res 2009;7(10):1655-62)
