Improved determination of variant erythrocytes at the glycophorin A (GPA) locus and variant frequency in patients treated with radioiodine for thyroid cancer.
Intrachromosomal rearrangements involving the RET and the adjacent H4 or ELE1 gene are very frequent events in thyroid cancer of children from Belarus after the Chernobyl reactor accident (Klugbauer et al., 1995).

As a first step towards investigating its possible role as a tumour suppressor gene in thyroid tumorigenesis, we have carried out a Southern blot analysis of the p16 gene locus in a series of cell lines derived from differentiated human thyroid cancers.

Structural studies of the thyrotropin receptor and Gs alpha in human thyroid cancers: low prevalence of mutations predicts infrequent involvement in malignant transformation.
Thyroglobulin transcripts were detected in nine of nine patients with metastatic thyroid cancer, seven of 78 patients with thyroid cancer and no current metastases (although of these seven patients, five had a history of metastatic disease that had been previously treated by surgery, one had a coexisting parathyroid cancer, and one had both papillary and follicular thyroid cancers), zero of six patients with benign thyroid disease, and zero of seven normal volunteers.
Structural genetic changes of tumor suppressor genes MTS-1/INK4A and MTS-2/INK4B were demonstrated in a variety of human cancers but not in thyroid cancer until now.
Because MTS-2 encodes the tumor suppressor p15, a protein related to the transforming growth factor-beta inhibition of many epithelial cells such as thyrocytes, we investigated MTS-1 and MTS-2 genes in 87 thyroid cancers (29 papillary, 26 follicular, 31 medullary, and 1 anaplastic), 8 goiters, and 38 control DNAs by using a semiquantitative polymerase chain reaction technique.
The present study was performed to evaluate the hitherto unknown prevalence of INT-2 gene amplification and its potential usefulness as prognostic marker in patients with human thyroid cancer.

This distinctive feature of RET mutations associated with Hirschsprung's disease and of the RET mutations associated with thyroid cancer indicates a basic biological difference between the mutational events leading to the different phenotypes.
A novel multicolor hybridization scheme applied to localization of a transcribed sequence (D10S170/H4) and deletion mapping in the thyroid cancer cell line TPC-1.
We, therefore, investigated the expression of VEGF messenger RNA (mRNA) and production of VEGF protein in cell lines from human primary and metastatic follicular (FTC-133, FTC-236, and FTC-238), papillary (TPC-1), Hürthle cell (XTC-1), and medullary thyroid cancers (MTC-1.1 and MTC-2.2), and in human thyroid tissues (papillary, follicular, medullary, and Hürthle cell cancers, follicular adenomas, and Graves' thyroid tissue) by Northern blot, immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA) studies.
The ZnF20 cDNA hybridized to multiple transcripts in a thyroid cancer cell line (8.0, 4.5 and 2 kb) that increased after cycloheximide treatment and decayed <2 h after addition of actinomycin D. The ZnF20 mRNA was overexpressed in three of six thyroid papillary carcinomas as compared with paired normal thyroid tissue controls.
Retinoic acid increases sodium/iodide symporter mRNA levels in human thyroid cancer cell lines and suppresses expression of functional symporter in nontransformed FRTL-5 rat thyroid cells.
We have shown that germline mutations of PTEN are present in individuals with two hamartoma syndromes: Cowden Syndrome, associated with a predisposition to breast and thyroid cancers, and Bannayan-Zonana syndrome.
For defined tumor types, expression of at least one of the SSX family members was most frequently observed in head and neck cancer (75%), followed by ovarian cancer (50%), malignant melanoma (43%), lymphoma (36%), colorectal cancer (27%) and breast cancer (23%), while leukemias and the few cases of leiomyosarcomas, seminomas and thyroid cancers were found not to express any SSX gene.
