Hyperthyroidism increased the mRNA expression of core clock genes and thyrotrophic embryonic factor (Tef), as well as the mesor and amplitude of brain and muscle Arnt-like protein-1 (Bmal1) and the mesor of nuclear receptor subfamily 1 (Nr1d1) group D member 1, when compared to euthyroid animals.
These results suggest that even mild chronic myocardial thyrotoxicosis, such as may occur in human hyperthyroidism, can cause tachycardia and associated changes in high energy phosphate compounds independent of an increase in SERCA II and alpha-MHC.
All these data indicated an association between low nutrient condition due to hyperthyroidism and increased (pro)renin receptor expression in these patients, suggesting that (pro)renin receptor expression could be increased in the process of stimulating intracellular energy production via activating autophagy function to compensate energy loss.
Adjust for age, gender and BMI, serum ZAG levels were positively related with serum free T3 (FT3), free T4 (FT4) levels and negatively correlated with serum total cholesterol (TC), low density lipoprotein cholesterol (LDLC) levels in hyperthyroidism subjects (all P < 0.01).
The MAGI3 and BACH2 variants were associated with an increased risk of hyperthyroidism, which was replicated in an independent cohort of patients with Graves' disease (OR: 1.37, 95% CI 1.22-1.54, P = 1.2×10(-7) and OR: 1.25, 95% CI 1.12-1.39, P = 6.2×10(-5)).
The aim of this study was evaluation of expression of Bcl-2 protein in peripheral blood T lymphocytes in hyperthyroid children due to Graves' disease (GD) before and after therapy with methimazole (MMI), in comparison with healthy controls.
Following treatment with iodine‑131, 30 of the 59 (50.8%) patients with hyperthyroidism were diagnosed with early‑stage hypothyroidism, and in the early‑stage hypothyroidism group, the mRNA expression levels of Bcl‑2 were significantly decreased (P<0.05), whereas those of Egr‑1 (P<0.05) were significantly increased, compared with the non‑early‑stage hypothyroidism group.
Determination of the kinetic parameters of the membrane-bound D-3-hydroxybutyrate dehydrogenase in liver of hyperthyroid rats reveals a decreased in maximal velocity (Vmax).
Serum levels of osteocalcin, alkaline phosphatase, terminal telopeptides of type β collagen, and tartrate-resistant acid phosphatase were higher in the hyperthyroid rats than in the control rats (all p < 0.05).
The serum osteocalcin levels and 24-hour urinary phosphorus excretion were found to be higher in the hyperthyroid group than in the control group (p<0.001, p=0.009).
The most significant predictors for pathogenic or unclassified variant changes in BRCA1 in ovarian cancer patients were a younger age of onset and a history of hyperthyroidism and infertility.
Individuals with hyperthyroidism exhibit concentrations of carbonic anhydrase I (CAI) in red blood cells that reflect the integrated serum thyroid hormone concentration over the preceding few months.
