Article Abstract
Objective: To investigate the relationship between thyroid functions and asymmetric dimethylarginine (ADMA), ischemia-modified albumin (IMA), and other metabolic laboratory markers in euthyroid adults and whether narrower thyroidal targets are required for lower metabolic risk.
Materials And Methods: Thyroid functions, antithyroid autoantibodies, and metabolic parameters were measured for 115 patients. Forty-seven had autoimmune thyroiditis (AIT). Analyses were performed according to cutoff values of 1, 2, 2.5, and 3 mIU/L for thyrotropin, 0.84 ng/dL for free thyroxine (fT4), and 3.59 ng/dL for free tri-iodothyronine (fT3).
Results: There was no relationship between thyrotropin and fT3 cutoff values and metabolic parameters. Only C-reactive protein was lower in the group with thyrotropin ≤2.5 μIU/L. A weak positive correlation was found between fT4 with IMA and IMA corrected for albumin (r = 0.187, P = .05; r = 0.204, P = .034, respectively). There was no difference between AIT and the metabolic laboratory parameters examined in the study.
Conclusion: This study is the first to evaluate ADMA in AIT. Narrower thyroid function targets are not required for better metabolic control in euthyroid adults.
Thyrotropin receptor (TSHR) and insulin-like growth factor 1 receptor (IGF-1R) have been shown to crosstalk in primary cultures of human thyrocytes (hThyros) and Graves' orbital fibroblasts. The phenomenon of TSHR/IGF-1R crosstalk has been largely studied in the pathogenesis of thyroid eye disease (TED) in human orbital fibroblasts. Here, we investigated the effects of inhibiting the IGF-1R-mediated contribution to crosstalk by linsitinib (Lins), a small-molecule IGF-1R kinase inhibitor, on TSH-induced regulation of thyroperoxidase (TPO) and thyroglobulin (TG) mRNAs and proteins in hThyros and on TPO and TG mRNAs and free thyroxine (fT4) levels in mice.
Chlorpyrifos (CPF) is a widely used organophosphate insecticide with serious toxicological effects on aquatic animals. Although extensively studied for neurotoxicity and endocrine disruption, its stage-specific effects on amphibian metamorphosis and receptor-level interactions remain unclear. This study investigated the effects of CPF on metamorphosis at environmentally relevant concentrations (1.
Objective: To identify key genes and potential molecular mechanisms associated with Hashimoto's thyroiditis (HT) to provide new insights for the development of diagnostic and therapeutic targets for this disease.
Methods: Differential expression analysis and weighted gene co-expression network analysis (WGCNA) were conducted to identify the differentially expressed genes (DEGs) associated with HT. A protein-protein interaction (PPI) network was used to obtain hub genes, with CD27 emerging as the key gene in HT.
Background: Thyroid hormones (THs) are essential for brain development. Numerous studies have identified significant links between thyroid dysfunction and cognitive function. However, research on the significance and necessity of thyroid function tests in diagnosis of neurological disorders is limited and subject to controversy.
Introduction: BRAFV600E mutation (BRAF) is common in papillary thyroid cancer (PTC), and most patients have an excellent outcome. However, a TERT-promoter mutation (pTERT) in the presence of BRAF (BRAFpTERT) has been demonstrated to confer a more aggressive behavior to PTC. Lymphocytic infiltration is often present in PTC.
