Effect of the ligands of thyroid hormone receptor on non-alcoholic fatty liver disease
… we examined the effect of the thyroid hormone triiodothyronine (T3) and the agonist of the thyroid hormone receptor β isoform (TRβ), GC-1, on fatty liver and steatohepatitis induced in rodents by a choline-deficient, methionine-restricted (CMD) diet. Male Fischer rats fed the CMD diet for 1 …

Preneoplastic hepatocyte hypothyroidism underlies hepatocellular carcinoma progression
… are mediated by the thyroid hormone 3,5,3’-L-triiodothyronine (T3) nuclear receptors (THRs), which act as transcription factors. THRs have also been implicated in tumorigenesis, although it is unclear whether they act as oncogenes or tumor suppressors. Here, experiments were performed to …

The Alteration of Thyroid Hormone Level during Liver Transplantation
"배경: 비갑상선질환 증후군은 triiodothyronine (T3)치가 단독으로 저하되어 있거나 T3 와 tyroxine (T4)치가 같이 저하되어있는 것이 특징이다. 이는 기아, 패혈증, 심근경색, 심장 혹은 비 심장수술 환자에서 관찰 되며, 어떤 심한 질병과도 동반될 수 있다. 원인은 명확히 알려져 있지 않으나, interleukine-6 (IL-6), tumor necrosis factor-a (TNF-a)와 같은 cytokines가 요소 중 하나로 제시되고 있다. 간이식수술은 cytokines의 급격한 변화를 겪는 …

Effect of Levothyroxine Administration on Hemostatic Analytes in Doberman Pinschers with von Willebrand's Disease
… thyroxine (T4), free thyroxine (fT4), 3,5,3â -triiodothyronine (T3), and thyroid stimulating hormone were measured on days 0, 2, and 30 of each treatment period. The dogs had markedly low plasma vWf:Ag concentrations (mean 8.9%; reference range 70-180%) and vWf:CBA (mean 11.1%; reference range …

Effects of Levothyroxine Adminstration and Withdrawal on the Hypothalamic-Pituitary-Thyroid Axis in Euthyroid Dogs
… dialysis, thyrotropin (TSH), and 3,5,3'-triiodothyronine (T3) were measured every 4 weeks during supplementation and for 16 weeks after levothyroxine was discontinued. Results: Mean serum T4 and fT4 were significantly higher and TSH was lower in all dogs during levothyroxine …

The Effects of Anesthesia and Surgery on Thyroid Function Tests in Dogs
… (T4), free T4 (fT4) by equilibrium dialysis, triiodothyronine (T3), reverse T3 (rT3) and thyroid-stimulating hormone (TSH) concentrations were measured in all samples. Results: Results of all thyroid function tests were not significantly different between control and anesthesia groups. Serum …

Thyroid hormones and breast cancer-prospective studies on incidence, mortality and prognostic factors
… factors. The association between total triiodothyronine (T3) levels and breast cancer risk was studied in 2185 women with146 incident breast cancer cases. The association of free T3 and free thyroxin (T4) levels in relation to breast cancer risk was studied in 676 breastcancer cases and …

Extrathyroidal thyroid hormone activation in ring doves
… in the presence of abundant substrate, reverse triiodothyronine (rT3), cofactor (dithiothreitol) and trace amounts of I¹²⁵-rT3. 5’D activity was measured as I¹²⁵ released from the labelled rT3 during the assay incubation time. The 5’D assay was validated for all ages studied to assure that the …

The role of Thyroid hormone Transporters Monocarboxylate Transporter 10 (MCT10) and Monocarboxylate Transporter 8 (MCT8) in extravillous trophoblasts.
… as a model of 1st trimester EVTs, we assessed 1) Triiodothyronine (T3) effects on gene expression and cell proliferation; 2) the effect of altered MCT8 or MCT10 expression on proliferation and apoptosis; and whether effects were T3-mediated. Methods: 1) Cell proliferation was assessed by the MTT …
