BACKGROUND It has been reported that overt and mild thyroid dysfunctions are associated with insulin resistance (IR). We performed this retrospective study to evaluate the relationships between thyroid-stimulating hormone (TSH) levels within the reference range and IR. MATERIAL AND METHODS A total of 447 outpatients were enrolled in this study: 298 with type 2 diabetes mellitus and 149 nondiabetic individuals. Based on a cutoff HbA1c value of 7%, diabetic patients were additionally divided into 2 groups: a high-HbA1c group (n=240) and a low-HbA1c group (n=58)...

Anaplastic thyroid cancer (ATC) constitutes less than 2% of total thyroid cancers but accounts for 20-40% of thyroid cancer-related deaths. Cancer stem cell drug resistance represents a primary factor hindering treatment. This study aimed to develop targeted agents against thyroid malignancy, focusing on individual and synergistic effects of HNHA (histone deacetylase), lenvatinib (FGFR), and sorafenib (tyrosine kinase) inhibitors. Patients with biochemically and histologically proven papillary thyroid cancer (PTC) and ATC were included...

BACKGROUND: There is a paucity of treatment options for bipolar depression. The use of triiodothyronine (T3) has been suggested as adjunctive treatment. METHODS: A search on Medline, Limo and ScienceDirect was performed using the search terms bipolar disorder, bipolar depression, treatment resistant, treatment refractory, thyroid hormones, triiodothyronine, T3, acceleration and augmentation. RESULTS: We retrieved three open studies, one comparative study, two double blind and one retrospective chart review...

Follicular thyroid cancer's (FTC) excellent long-term prognosis is mainly dependent on complete surgical removal and postoperative radioactive iodine (RAI) treatment. However, once the tumour becomes RAI refractory the 10-year disease specific survival rate drops below 10 %. The aim of our study was to evaluate the prognostic and biological role of the TRAIL system in FTC and to elucidate the influence of small molecule mediated antagonization of inhibitor of apoptosis proteins (IAPs) on TRAIL-sensitivity in vitro...

Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) induces apoptosis in malignant cells, but not in normal cells. As papillary thyroid carcinoma cells broadly expressed TRAIL receptors (death receptor 4 and death receptor 5) on their surface, TRAIL is considered as a promising drug for treatment of papillary thyroid carcinoma. However, resistance to TRAIL still be a big obstacle to achieve a satisfactory effect for cancer therapy. Here, we found that overexpression of miR-101 was able to sensitize papillary thyroid carcinoma cells to TRAIL treatment in vitro and in vivo...

AKT (also known as protein kinase B, PKB) plays an important role in cell survival or tumor progression. For these reasons, AKT is an emerging target for cancer therapeutics. Previously our studies showed that mitochondrial E3 ubiquitin protein ligase 1 (MUL1, also known as MULAN/GIDE/MAPL) is suppressed in head and neck cancer (HNC) and acts as negative regulator against AKT. However, the MUL1 regulatory mechanisms remain largely unknown. Here we report that cisplatin (CDDP) induces thyroid cancer cell death through MUL1-AKT axis...

After the creation of the Academy of Medical Sciences of Ukraine in 1993 the Research Center for Radiation Medicine was among the first institutions to join the Academy (fig. 1). Estab lishing the Academy was among the first steps of the independent Ukrainian government and aimed to provide a high level health care for population. It was extremely needed for the minimization of Chornobyl medical consequences. This choice was related to a growing recognition of the scientific research in fulfilling the Сenter's mission - study of the effects of low dose radiation on human body and radiation protection of the exposed population...

We have introduced a fabrication method for electrical impedance spectroscopy (EIS)-on-a-needle (EoN: EIS-on-a-needle) to locate target tissues in the body by measuring and analyzing differences in the electrical impedance between dissimilar biotissues. This paper describes the fabrication method of fine interdigitated electrodes (IDEs) at the tip of a hypodermic needle using a photoresist spray coating and flexible film photomask in the photolithography process. A polyethylene terephthalate (PET) heat shrink tube (HST) with a wall thickness of 25 µm is employed as the insulation and passivation layer...

Objective: To analyze the clinical characteristics of children with two types of thyroid hormone resistance (RTH) syndrome, and to detect the variants of thyroid hormone receptor alpha(TRα) and TRβ gene in children. Method: Two children with RTH were reported in regard to clinical manifestation, laboratory examination and genetic variants. Some related reports in literature were reviewed. Result: Case 1 was a girl, 10 years old, with thyroid enlargement for several days and without thyrotoxicosis. Laboratory work-up revealed that free thyroxine (FT(4)) was 65...

Obesity is associated with elevated plasma levels of glucocorticoids and reduced levels of thyroid hormones, both known to effect food intake and energy expenditure. Furthermore, tissue specific glucocorticoid metabolism is altered in obesity, increasing insulin resistance and cardiometabolic risk. The goal of this study was to examine whether these metabolic disturbances can be prevented with the isoflavone genistein in the ob/ob mouse, a model that resembles the phenotype in human obesity. Male ob/ob mice, aged 5 weeks, were fed either a genistein-rich diet (600 mg/kg) or a genistein-free diet for 4 weeks...

BACKGROUND: The objective of this study was to determine the effect of a home-based exercise program on fatigue, anxiety, quality of life, and immune function of thyroid cancer patients taking thyroid hormone replacement after thyroidectomy. METHOD: This quasi-experimental study with a non-equivalent control group included 43 outpatients taking thyroid hormone replacement after thyroidectomy (22 in experimental group and 21 in control group). After education about the home-based exercise program, subjects in the experimental group underwent 12 weeks of aerobic, resistance, and flexibility exercise...

Thyroid cancer is a multifaceted and therapeutically challenging disease and rapidly accumulating experimentally verified findings have considerably improve our understanding of the molecular mechanisms which underlie its development. Substantial fraction of information has been added into existing landscape of molecular oncology and we have started to develop a sharper understanding of the underlying mechanisms of thyroid cancer. Wealth of information demystified different intracellular signaling cascades which are frequently deregulated in thyroid cancer...

Thyroid hormone (TH) and TH receptors (TRs) α and β act by binding to TH response elements (TREs) in regulatory regions of target genes. This nuclear signaling is established as the canonical or type 1 pathway for TH action. Nevertheless, TRs also rapidly activate intracellular second-messenger signaling pathways independently of gene expression (noncanonical or type 3 TR signaling). To test the physiological relevance of noncanonical TR signaling, we generated knockin mice with a mutation in the TR DNA-binding domain that abrogates binding to DNA and leads to complete loss of canonical TH action...

The multi-target kinase inhibitor sorafenib has been approved for the treatment of patients with advanced differentiated thyroid cancer. However, different sensitivities to sorafenib have been observed, and few patients have benefited from sorafenib treatment in the long term. In the event of acquired resistance to sorafenib it is not beneficial to continue treatment in most patients. Autophagy can be induced in a variety of cancer treatments and plays an important role in cancer treatment. The role of autophagy in sorafenib treatment of thyroid cancer has not been fully demonstrated...

Resistance to thyroid hormone due to THRA mutations (RTHα) is a recently discovered genetic disease, displaying important variability in its clinical presentation. The mutations alter the function of TRα1, one of the two nuclear receptors for thyroid hormone. Our aim was to understand the relationship between specific THRA mutations and phenotype. We used CRISPR/Cas9 genome editing to generate 5 new mouse models of RTHα, with frameshift or missense mutations. Like human patients, mutant mice displayed a hypothyroid-like phenotype, with altered development...
