Iodide symporter gene expression in human thyroid tumors.


Expression of the Na+/I- symporter (NIS) gene was investigated by RT-PCR in a selected series of 26 primary thyroid carcinomas (19 papillary, 5 follicular, and 2 anaplastic). Fifteen follicular adenomas (11 "cold" and 4 "hot" adenomas) were also studied. Five of 19 papillary thyroid cancer did not express NIS messenger ribonucleic acid (mRNA). In all but 1… (More)
