The content of epidermal-growth-factor receptor (EGFr) and its relation to TSH-response were examined in 27 malignant thyroid tumors (5 follicular, 6 papillary, 5 medullary, 11 anaplastic carcinomas) and in 30 tumor-like lesions (21 hyperplastic goiters and 9 toxic adenomatous goiters). Normal 12 thyroid tissues adjacent to benign tumors with no evidence of macroscopic or microscopic abnormalities were used as control. All thyroid plasma membranes tested showed specific EGF binding. In membranes from toxic adenomas (2.18 +/- 0.73 fmoles/mg protein) and papillary carcinomas (2.80 +/- 0.80) the EGF binding was similar to that of normal thyroid membranes (2.32 +/- 0.73). Hyperplastic goiters showed an EGF binding (4.4 +/- 0.82) slightly higher than normal tissue. The highest and the lowest EGF binding values were found in anaplastic (11.8 +/- 2.78) and medullary (0.50 +/- 0.39) carcinomas, respectively. An inverse correlation between EGFr content and TSH-response was found when anaplastic thyroid tumors were compared to tumor-like lesions. However no correlation was observed in medullary carcinomas which also failed to respond to TSH and in papillary carcinomas which partially respond to thyrotropin.

D007457 Iodine Radioisotopes Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes. Radioisotopes, Iodine
D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid

D004815 Epidermal Growth Factor A 6-kDa polypeptide growth factor initially discovered in mouse submaxillary glands. Human epidermal growth factor was originally isolated from urine based on its ability to inhibit gastric secretion and called urogastrone. Epidermal growth factor exerts a wide variety of biological effects including the promotion of proliferation and differentiation of mesenchymal and EPITHELIAL CELLS. It is synthesized as a transmembrane protein which can be cleaved to release a soluble active form.

D000242 Cyclic AMP An adenine nucleotide containing one phosphate group which is esterified to both the 3'- and 5'-positions of the sugar moiety. It is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon, and ACTH.

D013961 Thyroid Gland A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.

D013972 Thyrotropin A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
