Thyroid hormones (TH) synthesis requires iodine, a scarce element whose recycling is mediated by the iodotyrosine dehalogenase (encoded by the DEHAL1 gene) through deiodination of mono- and di-iodotyrosines. In humans, biallelic mutations in DEHAL1 lead to a severe form of congenital hypothyroidism (CH) non detectable by neonatal screening programs, which involves the risk of mental retardation. The timing and triggering factors of this particular type of hyp...

Background: Metformin plays anti-tumoral roles in human cancers including breast and thyroid. However, its effects on metastatic lesions are undetermined. We studied the effects of metformin on bone metastasis of thyroid cancer.Method: Luciferase-tagged anaplastic FRO and follicular FTC 133 thyroid cancer cells were used. In vivo effects of metformin were evaluated in both ectopic tumor model and bone metastasis model generated by intratibial injection.<...

Introduction: Worldwide constantly rising incidence of thyroid cancer promotes research activities. Nowadays the most speculated issue is the clinical significance of BRAF mutation. For sure BRAF mutation is a cancer-specific somatic mutation consistent with papillary thyroid cancer phenotype, otherwise, its role in tumor aggressiveness, progression, and the overall poor outcome is controversial. As far as several clinical studies claim opposing opinions, the learning aspect o...

Background: Differentiated thyroid cancer (DTC) is usually associated with an excellent prognosis. The main cause of death is due to distant metastases, but distant metastatic DTC (dmDTC) presents an interpatient heterogeneity. Some patients with distant metastases live with stable disease for many years, while others die very early. Still no effective biomarkers are available to predict either which patients will eventually develop distant metastases or what will be the final...

Introduction: Surgical management of clinically N0 (cN0) patients with thyroid carcinomas remains debatable due to various reported frequencies of lymph node (LN) metastases. Preoperative ultrasound identifies only half of LN metastases found at surgery. The aim of this report was to present our experience with sentinel lymph node biopsy (SLNB) of jugulo-carotid regions, after methylene blue dye (MBD) mapping and frozen section analysis (FSA), in detection of LN metastases in ...
