PURPOSE OF REVIEW To discuss new insights regarding how sensitive (second-generation) thyroglobulin immunometric assays (TgIMAs), (functional sensitivities ≤0.10 μg/L) necessitate different approaches for postoperative thyroglobulin monitoring of patients with differentiated thyroid cancer (DTC), depending on the presence of thyroglobulin autoantibodies (TgAbs). RECENT FINDINGS Reliable low-r...

Experiments are described in which tanned red cells coated with a globulin fraction of human serum with a high titre of antibody to human thyroglobulin were agglutinated by saline extracts of human thyroid gland and thyroglobulin but not by other tissue extracts. It is suggested that the linkage is due to a specific antigen antibody reaction between cell-bound antithyroid antibody and thyroglob...

BACKGROUND Traditionally, the follow-up of differentiated thyroid carcinoma consists of periodic withdrawal from L-T4-suppressive therapy to allow performance of a highly sensitive serum Tg measurement to detect recurrences. We investigated Lens culinaris agglutinin-reactive thyroglobulin ratios in serum to evaluate in usefulness for detection of thyroid carcinoma. METHODS The study was condu...

Thyroglobulin labeled with L-[U-‘*C]tyrosine was prepared, purified, and iodinated in order to investigate the fate of the 3-carbon fragment which remains when 2 iodotyrosine residues (18 carbon atoms) in thyroglobulin react with each other in the course of thyroid hormonogenesis to form 1 hormone residue (15 carbon atoms). Incubation of hog thyroid slices with L-[U-‘*C]tyrosine led to the form...

Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. We investigated clinical outcomes of remnant thyroid ablation with a low radioiodine activity in Korean patients with low to intermediate-risk thyroid cancer. For remnant thyroid ablation, 176 patients received radioiodine of 1.1 GBq, under a s...

6 Asymptomatic Paget’s Disease — To Treat or Not to Treat Throughout most of the 20th century, thyroid carcinoma was considered a rare cancer with a low death rate. During the last 20 to 25 years, however, incidence rates of thyroid cancer have risen exponentially across the world. In combination with the low cause-specific mortality rate of thyroid cancer, this increase has led to huge numbers...

Pax proteins are transcription factors that control differentiation of several cell types. In adult organisms Pax-8 is expressed in the follicular thyroid cell where it interacts with sequences of thyroglobulin and thyroperoxidase promoters. In this study, we provide evidence indicating that Pax-8 protein levels regulate thyroglobulin gene transcription. The most critical approach consisted in ...
