GLP-1 receptors are ideal targets for preoperative imaging of benign insulinoma and for quantifying the beta cell mass. The existing clinical tracers targeting GLP-1R are all agonists with low specific activity and very high kidney uptake. In order to solve those issues we evaluated GLP-1R agonist Ex-4 and antagonist Ex(9-39) radioiodinated at Tyr40 side by side with [Nle14,Lys40(Ahx-DOTA-68Ga)NH2]Ex-4 (68Ga-Ex-4) used in the clinic. The Kd, Bmax, internalization and binding kinetics of [Nle14,125I-Tyr40-NH2]Ex-4 and [Nle14,125I-Tyr40-NH2]Ex(9-39) were studied in vitro using Ins-1E cells...

The effects of different doses of potassium iodate (KIO3) on the malignancy of thyroid cancer were investigated. Results showed that the proliferation, migration, and invasion of SW579 thyroid cancer cells were improved by 10(-6) M KIO3, which was associated with microRNA(miR)-146a deficit; 10(-2) M KIO3 significantly enhanced miR-146a level and suppressed SW579 cell proliferation, migration, and invasion. The diverse effects of KIO3 on SW579 cells were associated with the expression changes in miR-146a targets, Bcl-2, Bax, and caspase-3...

Thyroid hormones are crucial for the growth and maturation of many target tissues, especially the brain and skeleton. During critical periods in the first trimester of pregnancy, maternal thyroxine is essential for fetal development as it supplies thyroid hormone-dependent tissues. The ontogeny of mature thyroid function involves organogenesis, and maturation of the hypothalamus, pituitary and the thyroid gland; and it is almost complete by the 12th-14th gestational week. In case of maternal hypothyroidism, substitution with levothyroxine must be started in early pregnancy...

Contrasting results have been reported about the prevalence of thyroid autoimmunity (AT) and dysfunction (TD) in patients with psoriatic arthritis (PsA). In this study, we pointed to evaluate the incidence of new cases of clinical and subclinical TD in a broad group of patients with PsA versus a control group, matched by age and gender belonging to the same geographic area. PsA patients with TD were excluded firstly, and new cases of thyroid disorders were evaluated in 97 PsA patients and 97 matched controls, who had comparable iodine intake (median follow-up of 74 months in PsA versus 92 in controls)...

BACKGROUND/AIM: Beginning in 2011, the Food and Drug Administration (FDA) approved the use of multikinase inhibitors (MKIs) for medullary thyroid cancers (MTCs), and in 2013 MKIs were approved for metastatic differentiated thyroid cancers (DTCs). However, little is known about the use of chemotherapy in thyroid cancer patients. Thus, the goal of our study was to describe patterns of chemotherapy use, including MKIs, among DTC and MTC patients in the National Cancer Database (NCDB). METHODS: Chemotherapy use, along with other treatment types (surgery and radiation), was assessed between 2004 and 2013...

REVIEW
Dulani Kottahachchi, Duncan J Topliss
Immunoglobulin G4-related disease (IgG4-RD) is a new disease category involving many organ systems, including the endocrine system in general and the thyroid in particular. Since an initial association was made between hypothyroidism and autoimmune (IgG4-related) pancreatitis, more forms of IgG4-related thyroid disease (IgG4-RTD) have been recognized. Four subcategories of IgG4-RTD have so far been identified: Riedel thyroiditis (RT), fibrosing variant of Hashimoto thyroiditis (FVHT), IgG4-related Hashimoto thyroiditis, and Graves disease with elevated IgG4 levels...

BACKGROUND: Papillary thyroid cancer (PTC) prevalence is nearly 3 times higher in females than in males. This gender difference suggests that growth and progression of PTC might be influenced by female sex hormones. OBJECTIVES: To analyze the expression of both estrogen receptor (ER)-α and progesterone receptor (PR) by immunohistochemistry in 203 PTC patients. METHODS: ER-α and PR expression was evaluated in paraffin-embedded tumor tissue samples of 45 males and 158 females followed up for 7...

RESULTS OF THE SCREENING OF THYROIDS: Because of the March 2011 nuclear accident in Fukushima, Japan, the Fukushima Prefecture initiated a thyroid ultrasound examination program. The first cycle of examinations on all children (more than 300,000) of the Fukushima Prefecture identified 116 patients as having malignant or suspected malignant thyroid nodules, and in the second cycle 59 new cases were identified. According to the available data, the thyroid cancers found by the screening are unlikely to be due to radiation, but the possibility cannot be excluded...

Pupose: Although there are reports of vitamin D (VitD) insufficiency in immune-mediated hypothyroidism, an association between VitD and thyroid-stimulating hormone (TSH) levels has yet to be shown. We aim to examine VitD and TSH levels among postmenopausal women, as both conditions are more prevalent in elderly women. Methods: The clinic records of postmenopausal women during their routine maintenance visits were reviewed. All patients were examined for the symptoms related to thyroid function and osteoporosis...

In this study, we present a case of a 52-year-old male with a chondrosarcoma of the left lamina of the thyroid cartilage. Pre-operative evaluations detected typical calcifications and delineated the extent of the tumor. The patient underwent a total laryngectomy to ensure the complete resection of the tumor. The tumor was histopathologically found to consist of chondrocytes in a hyaline cartilage matrix. The patient's post-operative course has been successful apart from the permanent tracheostomy. Herien, we discuss the methods and rationales for the diagnosis and management of and recovery from this rare tumor, and also provide a review of the literature...

Hashimoto's thyroiditis (HT) is the most common organ-specific autoimmune disease and is believed to be a predominately T cell-mediated autoimmunity. Signal transducer and activator of transcription (STAT)3 is a crucial transcription factor of T cell-mediated immunity, with key roles in the proliferation and migration of T helper (Th) cells, differentiation of Th cells into Th17 cells, and the balance between Treg cells and Th17 cells. Flavonoid luteolin has been shown to markedly inhibit Tyr705 activation/phosphorylation of STAT3 and exert anti-inflammatory effects in multiple sclerosis...
