In normal thyroid tissue, staining of hNIS protein was heterogeneous and limited to a minority of follicular cells that were in close contact with capillary vessels. In positive cells, immunostaining was limited to the basolateral membrane. In contrast, in Graves\u2019 disease the majority of follicular cells expressed the hNIS protein. In autoimmune thyroiditis, the number of hNIS-positive cells, was similar to that found in normal tissue. These positive cells were found essentially close to lymphocytic infiltrates. This observation supports the concept of hNIS as an autoantigen. In diffuse nodular hyperplasia, hNIS staining was heterogeneous, but the number of hNIS-positive cells exceeded that found in normal tissue. In well differentiated follicular or papillary carcinoma, the number of hNIS-positive cells was significantly lower than in normal tissue. In poorly differentiated follicular carcinoma, the number of hNIS-positive cells was less than that found in well differentiated carcinoma, or there were no positive cells. Interestingly, in all of these thyroid tissues, the number of follicular cells exhibiting TSH receptor (TSHR) immunoreactivity was greater than the number of hNIS-positive cells. As hNIS expression appears to be related to TSHR stimulation, the decreased number of TSHR-positive cells in cancers may contribute to the reduced capacity of neoplastic cells to concentrate iodide. In one patient with a follicular cancer with an absence of hNIS immunostaining, the total body 131I scan showed no uptake in metastatic tissue. In three cancers with positive hNIS cells, the 131I scan showed uptake in lymph node metastases. This suggests that immunodetection of hNIS could predict radioiodine uptake in thyroid cancers.<\/jats:p>","DOI":"10.1210\/jcem.83.11.5262","type":"journal-article","created":{"date-parts":[[2014,1,8]],"date-time":"2014-01-08T17:02:29Z","timestamp":1389200549000},"page":"4102-4106","source":"Crossref","is-referenced-by-count":6,"title":["Na+\/I\u2212 Symporter Distribution in Human Thyroid Tissues: An Immunohistochemical Study1"],"prefix":"10.1210","volume":"83","author":[{"given":"Bernard","family":"Caillou","sequence":"first","affiliation":[{"name":"Departments of Pathology (B.C., M.T), 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fre\u0301de\u0301ric","family":"Troalen","sequence":"additional","affiliation":[{"name":"Clinical Biology (F.T., J.-M.B.), Institut Gustave-Roussy, 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Baudin","sequence":"additional","affiliation":[{"name":"Nuclear Medicine (E.B., M.S.), 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monique","family":"Talbot","sequence":"additional","affiliation":[{"name":"Departments of Pathology (B.C., M.T), 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Se\u0301bastiano","family":"Filetti","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina Sperimentale e Clinica, Policlinico Mater Domini (S.F.), 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Schlumberger","sequence":"additional","affiliation":[{"name":"Nuclear Medicine (E.B., M.S.), 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Michel","family":"Bidart","sequence":"additional","affiliation":[{"name":"Clinical Biology (F.T., J.-M.B.), Institut Gustave-Roussy, 94805 Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","reference":[{"key":"2020071619403658600_R1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1016\/0304-4157(93)90017-I","article-title":"Iodide transport in the thyroid gland.","volume":"1154","year":"1993","journal-title":"Biochim Biophys Acta"},{"key":"2020071619403658600_R2","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1038\/379458a0","article-title":"Cloning and characterization of the thyroid iodide transporter.","volume":"379","author":"Dai","year":"1996","journal-title":"Nature"},{"key":"2020071619403658600_R3","doi-asserted-by":"crossref","first-page":"27230","DOI":"10.1074\/jbc.272.43.27230","article-title":"Thyroid symporter.
