Regulation of mitochondrial biogenesis by thyroid hormone - 0 views

  •  
    Study describes the T3 effect on mitochondrial biogenesis.  T3 interacts with receptors involved with mitochondrial biogenesis in 3 ways: thyroid hormone receptors (TR), thyroid hormone receptor elements (TRE), and a combination of the two.

Thyroid Hormone Receptor Agonists Reduce Serum Cholesterol Independent of the LDL Receptor - 0 views

  •  
    New study shows that T3 and thyroid hormone agonists reduce LDL.  This is independent that LDL receptors.  Previously, it was thought that T3 increased LDL receptor expression.  But, this study shows that T3 lowers LDL independent of the LDL receptors.

Thyroid hormone receptors and resistance to thyroid hormone disorders - 0 views

  •  
    Great review on thyroid hormone receptors alpha and beta, which are nuclear receptors.

Thyroid Hormone Action Is Disrupted by Bisphenol A as an Antagonist - 0 views

  •  
    Bisphenol A (BPA) shown to interfere with the T3 and thyroid hormone receptor interaction.  This study even showed that BPA inhibited thyroid receptor transcription.

  •  
    T3, and T4 for that matter, increases SHBG.  This would be a novel method to determine thyroid hormone receptor insensitivity or resistance.

Specific 3,3′,5′-Triiodothyronine (Reverse T3) Binding Sites on Rat Liver Pla... - 0 views

  •  
    rat model finds T4 and rT3 receptors at plasma membrane.  T3 was found to bind with lower affinity than rT3 and T4 at the same receptor binding site.

Estradiol-induced proliferation of papillary and follicular thyroid cancer ce... - 0 views

  •  
    Estradiol increased thyroid papillary and follicular cancer cells via both ER alpha and ER beta in this study.  What is also interesting is that estradiol did not increase PR expression.

  •  
    Study finds T3 effects on ER-alpha is likely a non-genomic pathway.  This study found a down regulation of ER-alpha in tumor cell lines by T3.

PLOS ONE: Overexpression of the Mitochondrial T3 Receptor p43 Induces a Shift in Skelet... - 0 views

  •  
    T3 induces beneficial oxidative changes in muscles through its interaction with mitochondrial receptors.  PGC-1alpha and PPAR-gamma were involved in this process.  The important point here is that T3 is increasing oxidative function of muscle through interaction with mitochondria.
