Thyroglobulin (Tg) is a precursor for thyroid hormone, specifically synthesized by follicular cells upon stimulation the stimulating hormone (TSH). Damage to caused benign or malignant diseases cause release of Tg into circulation. Differentiated cancer (DTC) most common endocrine malignancy, which has an excellent prognosis if detected and treated early. This review describes clinical laborato...
A 35-year-old woman was determined to have an ovarian cyst and underwent a right ovarian cystectomy at 10 weeks of gestation. A histopathological examination revealed follicular carcinoma arising in a teratoma. No evidence of metastasis was found after delivery. She underwent a total thyroidectomy, followed by radioactive iodine (RAI) therapy. However, her serum thyroglobulin level increased to...
Recently we have developed an assay method for peroxidase-catalyzed coupling of iodotyronine residues of thyroglobulin, which is applicable to human diseased thyroid tissues. In the present study, the assay method as well as usual peroxidase assay methods were applied to thyroids of three patients (No. 1: familial goiter with impaired thyroglobulin synthesis, No. 2: mild chronic thyroiditis, No...
Thyroglobulin obtained from guinea pigs was examined by Na dodecyl-SO4-polyacrylamide gel electrophoresis after reduction and alkylation. In contrast to thyroglobulin from other mammalian sources, only three groups of polypeptide chains accounted for 95% or more of the protein. Determinations of the molecular weights of these purified proteins by equilibrium centrifugation in 6 M guanidine HCl ...
Gel electrophoresis of reduced thyroglobulin from normal human thyroids showed five major iodinated components, with estimated molecular masses of >300,000 daltons (14% of thyroglobulin’s iodine), 230,000 (30%), 45,000 (4.5%), 26,000 (17%), and 18,000 (4%). The 26,000and 18,000-dalton components had over 50% of their iodine as thyroxine. The 26,000-dalton iodopeptide had a single NHz-terminal,...
