The basic mechanisms underlying thyroid growth and proliferation in thyroid cancer are still incompletely characterized. Lithium inhibits GSK3beta and affects via phosphorylation the degradation of free beta-catenin, a potent transcription factor. Hence, using lithium as a model to modulate the wnt/beta-catenin pathway, we investigated its potential activation in-vitro in neoplastic human thyroid cell lines (FTC133, NPA).Our results show that lithium fun...
