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.<...

Objective: Mounting evidence has shown an increased risk of gestational diabetes mellitus (GDM) in association with elevated exposure to air pollution. However, limited evidence is available concerning the effect of specific air pollutant(s) on GDM incidence.Methods: We conducted this case-control study on 6717 mothers with GDM diagnosed in 2006–2013 and 6717 age- and year of delivery-matched controls to further address the risk of GDM in relation t...

IntroductionAdrenocortical Carcinoma (ACC) is a rare aggressive cancer which carries a poor prognosis. Adjuvant mitotane improves survival but is limited by poor response rates and resistance following tumour recurrence. Mitotane’s efficacy has been attributed to intracellular accumulation of toxic free cholesterol (FC) predominantly through inhibition of cholesterol storage through SOAT1. Yet SOAT1 specific inhibitors demonstrate inferior efficacy ...

Decamethylcyclopentasiloxane(D5) is one of the most common chemical ingredient for cosmetic products, cleansing agents, hairdye, dry cleaning solvent and personal hygiene supplies. D5 is also known as estrogenic chemical. It can be absorbed through skin, airosol, and even oraly. People are exposed to D5 in daily environment. However, the risk of prenatal exposure to D5 has not yet been fully understood. Recent research shows that imbalance of dam’s estrogen induces brain ...

BackgroundsThe study aimed to explore the characteristics of glucolipid metabolism in patients with nonfunctional adrenal incidentaloma(NFAI). And investigate the relationship between these factors and insulin resistance, islet beta cell function.MethodsThis study enrolled eight patients with nonfunctional adrenal incidentaloma and five healthy controls(HCs). These data were recorded including body measuremen...

Mitochondria play a key role in hormone biosynthesis and involve in renal cell proliferation by producing about 90% of cellular energy and controlling cell apoptosis. Doxorubicin is commonly used for many tumor treatments. However, its clinical utility is limited by the adverse reactions, which are known to be nephrotoxic. The mechanism by which doxorubicin induced kidney damage is still not completely understood, however nephrotoxicity by doxorubicin might be related to mitoc...

Calcium signaling plays a regulatory role in the events of cellular proliferation. In immunocytes such as T cells, B cells, mast cells and many other cell types, Ca2+ signals show to control the proliferation, differentiation, and function. Furthermore, Ca2+ has been shown to act as a second messenger to regulate innate immune cell function and activation. Here, we found that loss of Nckx3, a potassium-dependent Na+ /Ca2+</...

Background: Graves’ disease (GD) is an autoimmune disease caused by autoantibody targeting the thyrotropin receptor (TSHR) in the thyroid gland, resulting in hyperthyroidism with an annual incidence of 15 to 80/100,000 people worldwide. Current mainstream treatments for GD include aggressive treatment with radioiodine and thyroidectomy or unspecific immune-modulating therapy with glucocorticoids, antithyroid medications or anti-CD20 antibodies like Rituximab. Therefore, o...

Objective: To investigate the prevalence of hyperuricemia in Chinese population, and the association between serum concentrations of uric acid and related metabolic disorders.Methods: This study was based on de-identified hospital information system (HIS) data collected from four tertiary hospitals in three provinces of China. A total of 432,002 patients with at least one medical visit recorded SUA measurement were screened and 374,506 were enrolled. Hyp...

A 52-year man came to Emergency Department with Atrial Fibrillation with rapid ventricular response due to amiodarone induced thyrotoxicosis (AIT). The patient was found tachi-arrhythmic (153 beats per minute), tachypnoic (27 breaths per minute) and with intense hyperidrosis. His first blood test documented thyroid stimulating hormone (TSH) <0.01 mUI/l, free triiodothyronine (fT3) 20.0 pmol/l and free thyroxine (fT4) over 100 pmol/l. Thyroid ultrasonography revealed an enl...
