Summary
Zebrafish thyroid development involves conserved genes and Notch signaling. This pathway, including jag1a/jag1b ligands, is crucial for organogenesis and may link JAG1 variants to congenital hypothyroidism.
Area of Science:
- Developmental Biology
- Endocrinology
- Genetics
Background:
- Zebrafish thyroid development is unique but shares conserved genes with mammals.
- Congenital hypothyroidism research seeks novel genetic and environmental factors.
- Notch signaling is increasingly recognized for its role in thyroid development.
Purpose of the Study:
- To review the role of Notch signaling in zebrafish thyroid organogenesis.
- To examine the specific functions of jag1a and jag1b ligands.
- To discuss the implications of JAG1 variants in congenital thyroid defects.
Main Methods:
- Literature review of zebrafish thyroid development.
- Analysis of gene conservation between zebrafish and mammals.
- Focus on Notch signaling pathway components and ligands.
Main Results:
- Notch signaling is essential throughout zebrafish thyroid organogenesis.
- Jag1a and jag1b ligands have distinct roles in thyroid development.
- Evidence suggests a link between JAG1 variants and congenital thyroid disorders.
Conclusions:
- Notch signaling is a key regulator of zebrafish thyroid development.
- Understanding these pathways can inform research into congenital hypothyroidism.
- Further investigation into JAG1 variants is warranted for human thyroid defect studies.

03:14Notch Signaling Pathway
6.7K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

01:20Synthesis and Regulation of Thyroid Hormones
8.4K
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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.5K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

01:23The Thyroid Gland
8.1K
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...

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...

01:16TGF - β Signaling Pathway
10.7K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
