Thyroid cancer constitutes the most frequent endocrine neoplasia. Targeted expression of rearranged during transfection (RET)/papillary thyroid carcinoma (PTC) and V600E V-raf murine sarcoma viral oncogene homolog B1 (BRAF) to the thyroid glands of transgenic mice results in tumours similar to those of human PTC, providing evidence for the involvement of these oncogenes in PTC. Kato et al. developed a mouse model that mimics the full spectrum of the human follicular form of thyroid cancer (FTC). FTC rapidly develops in these mice through introduction of the thyroid hormone receptor β (THRB)PV mutant on the background of the inactivated THRB wt locus. Our aim was to verify if, in the context of human follicular thyroid carcinogenesis, THRB acted as a tumour suppressor gene. We screened for mutations of the THRB gene in the hot-spot region, spanning exons 7–10, in 51 thyroid tumours and six thyroid cancer cell lines by PCR and direct sequencing. We did not find mutations in any of the tumours or cell lines analysed. Our findings suggest that, in contrast to the findings on the THRB-mutant transgenic mice, THRB gene mutations are not a relevant mechanism for human thyroid carcinogenesis.

Thyroid Hormone Receptor Β

Thyroid hormone analogs with selective actions through specific thyroid hormone receptor (TR) subtypes are of great interest. They might offer the possibility of mimicking physiological actions of thyroid hormone with receptor subtype or tissue specificity with therapeutic aims. They are also pharmacological tools to dissect biochemical pathways mediated by specific receptor subtypes, in a complementary way to mouse genetic modifications. In this work, we studied the in vivo activity in developing rats of two thyroid hormone agonists, the TRβ-selective GC-24 and the TRα-selective CO23. Our principal goal was to check whether these compounds were active in the rat brain. Analog activity was assessed by measuring the expression of thyroid hormone target genes in liver, heart, and brain, after administration to hypothyroid rats. GC-24 was very selective for TRβ and lacked activity on the brain. On the other hand, CO23 was active in liver, heart, and brain on genes regulated by either TRα or TRβ. This compound, previously shown to be TRα-selective in tadpoles, displayed no selectivity in the rat in vivo.

Resistance to thyroid hormone (RTH) is a syndrome characterized by impaired sensitivity of tissues to thyroid hormone (TH). The alteration of TH-binding proteins, such as in Familial Dysalbuminemic Hyperthyroxinemia (FDH), can mimic the abnormal serum thyroid tests typical of RTH. We aimed to characterize a population referred to our center with suspected RTH and estimate the proportion of patients with FDH. For 303 different families, we collected clinical and hormonal data and sequenced the thyroid hormone receptor β gene (THRB) and exon 7 of the albumin gene (ALB). We found 56 THRB variants (i.e., 38% of the 303 index cases, called RTHβ group). Among the samples screened for FDH variants, 18% had the variant R218H in ALB (FDH group); in addition, 71% of the cases had neither variant (non-FDH/RTHβ group). Patients with FDH had significantly lower free T3 (fT3) and free T4 (fT4) levels and more often an isolated elevation of fT4 than RTHβ patients. Clinically, patients with FDH had fewer symptoms than patients with RTHβ. Our study suggests that FDH should be systematically considered when examining patients suspected of having RTH. In most cases, they present no clinical symptoms, and their biochemical alterations show an elevation of fT4 levels, while fT3 levels are 1.11 times below the upper limit of the assay.
