HISTONE DEACETYLASE INHIBITORS IN DIAGNOSIS AND TREATMENT OFTHYROID NEOPLASMS

摘要

Disclosed herein are novel approaches to thyroid cancer therapy. These approaches include methods to enhance thyroid specific gene expression, for example methods to enhance expression of thyroglobulin and/or the Na+/I- symporter in thyroid cancer cells. Enhanced expression of thyroid-specific genes promotes cellular differentiation and reduces biologically aggressive behavior such as invasion and metastasis. In addition, enhanced expression o f thyroglobulin and/or the Na+/I- symporter increases the ability of thyroid cancer cells to concentrate iodine or iodide, thereby making the cells more susceptible to radioactive iodine therapy. Also disclosed herein are methods for detecting thyroid neoplasms in a subject, by administering a therapeutically effective amount of a histone deacetylase inhibitor, administering a detectable agent whose uptake or concentration in thyroid cells is increased by administration of the histone deacetylase inhibitor, a nd detecting the detectable agent.
