Insights

Activating the Notch pathway in medullary thyroid cancer (MTC) suppresses Achaete-Scute Complex Like 1 (ASCL1) expression and tumor growth. This suggests Notch pathway activation is a promising targeted therapy for MTC.

Area of Science:

  • Endocrinology
  • Molecular Biology
  • Oncology

Background:

  • The Notch pathway is crucial for neuroendocrine cell development, including thyroid C-cells.
  • Achaete-Scute Complex Like 1 (ASCL1), a transcription factor, is linked to poor prognosis in neuroendocrine cancers.
  • Medullary thyroid cancer (MTC) originates from thyroid C-cells and typically exhibits inactive Notch signaling.

Purpose of the Study:

  • To investigate the role of Notch pathway inactivity in MTC pathogenesis.
  • To explore the therapeutic potential of Notch pathway activation in MTC.

Main Methods:

  • In vitro studies involving artificial induction of Notch signaling in MTC cells.
  • In vivo studies using an animal model of MTC treated with pharmacological Notch pathway activators.

Main Results:

  • Artificial Notch signaling induction suppressed ASCL1 expression, cell growth, and hormone secretion in MTC cells.
  • Pharmacological activation of the Notch pathway significantly inhibited tumor growth in an MTC animal model.

Conclusions:

  • Notch pathway inactivation contributes to MTC development by altering ASCL1 expression.
  • Targeted activation of the Notch pathway represents a potential therapeutic strategy for treating MTC.

Notch Signaling Pathway03:14

Notch Signaling Pathway

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 until 1985...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

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...
Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
Synthesis and Regulation of Thyroid Hormones01:20

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...
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...
