BACKGROUND: Diabetes has recently been identified as a risk factor for a variety of cancers, possibly due to hyperinsulinemia or exogenous insulin use. Thyroid cancer is the most common endocrine malignancy, and its incidence has been exponentially increasing worldwide at an alarming rate. The aim of this study was to establish whether insulin use affects thyroid cancer development and progression, specifically cell proliferation and migration in vitro. METHODS: In this study, we investigated the effects of the insulin agents most commonly used in the clinic, regular human insulin (HI) and insulin glargine (IG), on the proliferation and migration of thyroid cells...

Purpose/aim of the study: Graves' ophthalmopathy (GO) is closely related to the thyroid autoimmune disorder Graves' disease. Previous studies have suggested roles for thyroidal CD8+  T cells and autoimmunity against calsequestrin-1 (CASQ)-1 in the link between thyroidal and orbital autoimmune reactions in GO. A role for autoimmunity against CollXIII has also been suggested. In this study, we aimed to investigate correlations between some thyroidal and peripheral blood T-cell subsets and thyroidal T-cell reactivity against CASQ1 and CollXIII in patients with GO...

BACKGROUND: Paradoxically, elderly persons with type 2 diabetes mellitus (T2DM) fracture despite having higher bone density than nondiabetics. Systemic factors associated with aging and T2DM may have detrimental, local effects on the skeleton. One such factor could be by altering the microenvironment of the mesenchymal stem cells (MSCs), multipotent progenitors capable of differentiating into adipocytes or osteoblasts. METHODS: Sera were obtained from four participant groups (n = 40 total, 10 per group): (1) young women with normal glucose tolerance (NGTY), (2) postmenopausal women with NGT), (3) postmenopausal women with impaired glucose tolerance (IGT), and (4) postmenopausal women with T2DM...
