Insights

Thyroid hormone receptors (TRs) play complex roles in cancer. Aberrant TR expression impacts hepatocellular carcinoma (HCC) development and metastasis, highlighting potential therapeutic targets.

Area of Science:

  • Endocrinology
  • Molecular Biology
  • Oncology

Background:

  • Thyroid hormone 3,3',5-triiodo-L-thyronine (T3) regulates vital physiological processes via Thyroid Hormone Receptors (TRs).
  • TRs, often heterodimerizing with Retinoid X Receptors (RXRs), influence gene expression.
  • TRs exhibit dual roles in tumorigenesis, acting as tumor suppressors but also linked to metastasis when overexpressed.

Purpose of the Study:

  • To review recent findings on the role of TRs in hepatocellular carcinoma (HCC).
  • To explore the complex and context-specific functions of TR isoforms in cancer development.

Main Methods:

  • Literature review of studies investigating TRs in hepatocellular carcinoma.
  • Analysis of signaling pathways and coregulator interactions involving T3/TR.

Main Results:

  • Aberrant expression of TR isoforms has differential effects on HCC development and progression.
  • TRs' tumor suppressor roles contrast with associations between wild-type TR overexpression and metastasis.
  • Cross-talk between T3/TR signaling and other pathways influences tumor behavior.

Conclusions:

  • Understanding T3/TR signaling complexity in HCC is crucial for identifying novel therapeutic strategies.
  • TRs represent potential therapeutic targets for hepatocellular carcinoma treatment.

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
Hyperthyroidism I: Introduction01:25

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
Hypothyroidism II: Pathophysiology01:23

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
The Thyroid Gland01:23

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
